 # 2024 Changelog
 
+### <a id="242"></a> ClickHouse release 24.2, 2024-02-29
+
+#### Backward Incompatible Change
+* Validate suspicious/experimental types in nested types. Previously we didn't validate such types (except JSON) in nested types like Array/Tuple/Map. [#59385](https://github.com/ClickHouse/ClickHouse/pull/59385) ([Kruglov Pavel](https://github.com/Avogar)).
+* Add sanity check for number of threads and block sizes. [#60138](https://github.com/ClickHouse/ClickHouse/pull/60138) ([Raúl Marín](https://github.com/Algunenano)).
+* Don't infer floats in exponential notation by default. Add a setting `input_format_try_infer_exponent_floats` that will restore previous behaviour (disabled by default). Closes [#59476](https://github.com/ClickHouse/ClickHouse/issues/59476). [#59500](https://github.com/ClickHouse/ClickHouse/pull/59500) ([Kruglov Pavel](https://github.com/Avogar)).
+* Allow alter operations to be surrounded by parenthesis. The emission of parentheses can be controlled by the `format_alter_operations_with_parentheses` config. By default, in formatted queries the parentheses are emitted as we store the formatted alter operations in some places as metadata (e.g.: mutations). The new syntax clarifies some of the queries where alter operations end in a list. E.g.: `ALTER TABLE x MODIFY TTL date GROUP BY a, b, DROP COLUMN c` cannot be parsed properly with the old syntax. In the new syntax the query `ALTER TABLE x (MODIFY TTL date GROUP BY a, b), (DROP COLUMN c)` is obvious. Older versions are not able to read the new syntax, therefore using the new syntax might cause issues if newer and older version of ClickHouse are mixed in a single cluster. [#59532](https://github.com/ClickHouse/ClickHouse/pull/59532) ([János Benjamin Antal](https://github.com/antaljanosbenjamin)).
+
+#### New Feature
+* Added new syntax which allows to specify definer user in View/Materialized View. This allows to execute selects/inserts from views without explicit grants for underlying tables. So, a View will encapsulate the grants. [#54901](https://github.com/ClickHouse/ClickHouse/pull/54901) [#60439](https://github.com/ClickHouse/ClickHouse/pull/60439) ([pufit](https://github.com/pufit)).
+* Try to detect file format automatically during schema inference if it's unknown in `file/s3/hdfs/url/azureBlobStorage` engines. Closes [#50576](https://github.com/ClickHouse/ClickHouse/issues/50576). [#59092](https://github.com/ClickHouse/ClickHouse/pull/59092) ([Kruglov Pavel](https://github.com/Avogar)).
+* Implement auto-adjustment for asynchronous insert timeouts. The following settings are introduced: async_insert_poll_timeout_ms, async_insert_use_adaptive_busy_timeout, async_insert_busy_timeout_min_ms, async_insert_busy_timeout_max_ms, async_insert_busy_timeout_increase_rate, async_insert_busy_timeout_decrease_rate. [#58486](https://github.com/ClickHouse/ClickHouse/pull/58486) ([Julia Kartseva](https://github.com/jkartseva)).
+* Allow to set up a quota for maximum sequential login failures. [#54737](https://github.com/ClickHouse/ClickHouse/pull/54737) ([Alexey Gerasimchuck](https://github.com/Demilivor)).
+* A new aggregate function `groupArrayIntersect`. Follows up: [#49862](https://github.com/ClickHouse/ClickHouse/issues/49862). [#59598](https://github.com/ClickHouse/ClickHouse/pull/59598) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
+* Backup & Restore support for `AzureBlobStorage`. Resolves [#50747](https://github.com/ClickHouse/ClickHouse/issues/50747). [#56988](https://github.com/ClickHouse/ClickHouse/pull/56988) ([SmitaRKulkarni](https://github.com/SmitaRKulkarni)).
+* The user can now specify the template string directly in the query using `format_schema_rows_template` as an alternative to `format_template_row`. Closes [#31363](https://github.com/ClickHouse/ClickHouse/issues/31363). [#59088](https://github.com/ClickHouse/ClickHouse/pull/59088) ([Shaun Struwig](https://github.com/Blargian)).
+* Implemented automatic conversion of merge tree tables of different kinds to replicated engine. Create empty `convert_to_replicated` file in table's data directory (`/clickhouse/store/xxx/xxxyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy/`) and that table will be converted automatically on next server start. [#57798](https://github.com/ClickHouse/ClickHouse/pull/57798) ([Kirill](https://github.com/kirillgarbar)).
+* Added query `ALTER TABLE table FORGET PARTITION partition` that removes ZooKeeper nodes, related to an empty partition. [#59507](https://github.com/ClickHouse/ClickHouse/pull/59507) ([Sergei Trifonov](https://github.com/serxa)). This is an expert-level feature.
+* Support JWT credentials file for the NATS table engine. [#59543](https://github.com/ClickHouse/ClickHouse/pull/59543) ([Nickolaj Jepsen](https://github.com/nickolaj-jepsen)).
+* Implemented `system.dns_cache` table, which can be useful for debugging DNS issues. [#59856](https://github.com/ClickHouse/ClickHouse/pull/59856) ([Kirill Nikiforov](https://github.com/allmazz)).
+* The codec `LZ4HC` will accept a new level 2, which is faster than the previous minimum level 3, at the expense of less compression. In previous versions, `LZ4HC(2)` and less was the same as `LZ4HC(3)`. Author: [Cyan4973](https://github.com/Cyan4973). [#60090](https://github.com/ClickHouse/ClickHouse/pull/60090) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Implemented `system.dns_cache` table, which can be useful for debugging DNS issues. New server setting dns_cache_max_size. [#60257](https://github.com/ClickHouse/ClickHouse/pull/60257) ([Kirill Nikiforov](https://github.com/allmazz)).
+* Support single-argument version for the `merge` table function, as `merge(['db_name', ] 'tables_regexp')`. [#60372](https://github.com/ClickHouse/ClickHouse/pull/60372) ([豪肥肥](https://github.com/HowePa)).
+* Support negative positional arguments. Closes [#57736](https://github.com/ClickHouse/ClickHouse/issues/57736). [#58292](https://github.com/ClickHouse/ClickHouse/pull/58292) ([flynn](https://github.com/ucasfl)).
+* Support specifying a set of permitted users for specific S3 settings in config using `user` key. [#60144](https://github.com/ClickHouse/ClickHouse/pull/60144) ([Antonio Andelic](https://github.com/antonio2368)).
+* Added table function `mergeTreeIndex`. It represents the contents of index and marks files of `MergeTree` tables. It can be used for introspection. Syntax: `mergeTreeIndex(database, table, [with_marks = true])` where `database.table` is an existing table with `MergeTree` engine. [#58140](https://github.com/ClickHouse/ClickHouse/pull/58140) ([Anton Popov](https://github.com/CurtizJ)).
+
+#### Experimental Feature
+* Added function `seriesOutliersDetectTukey` to detect outliers in series data using Tukey's fences algorithm. [#58632](https://github.com/ClickHouse/ClickHouse/pull/58632) ([Bhavna Jindal](https://github.com/bhavnajindal)). Keep in mind that the behavior will be changed in the next patch release.
+* Add function `variantType` that returns Enum with variant type name for each row. [#59398](https://github.com/ClickHouse/ClickHouse/pull/59398) ([Kruglov Pavel](https://github.com/Avogar)).
+* Support `LEFT JOIN`, `ALL INNER JOIN`, and simple subqueries for parallel replicas (only with analyzer). New setting `parallel_replicas_prefer_local_join` chooses local `JOIN` execution (by default) vs `GLOBAL JOIN`. All tables should exist on every replica from `cluster_for_parallel_replicas`. New settings `min_external_table_block_size_rows` and `min_external_table_block_size_bytes` are used to squash small blocks that are sent for temporary tables (only with analyzer). [#58916](https://github.com/ClickHouse/ClickHouse/pull/58916) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
+* Allow concurrent table creation in the `Replicated` database during adding or recovering a new replica. [#59277](https://github.com/ClickHouse/ClickHouse/pull/59277) ([Konstantin Bogdanov](https://github.com/thevar1able)).
+* Implement comparison operator for `Variant` values and proper Field inserting into `Variant` column. Don't allow creating `Variant` type with similar variant types by default (allow uder a setting `allow_suspicious_variant_types`) Closes [#59996](https://github.com/ClickHouse/ClickHouse/issues/59996). Closes [#59850](https://github.com/ClickHouse/ClickHouse/issues/59850). [#60198](https://github.com/ClickHouse/ClickHouse/pull/60198) ([Kruglov Pavel](https://github.com/Avogar)).
+* Disable parallel replicas JOIN with CTE (not analyzer) [#59239](https://github.com/ClickHouse/ClickHouse/pull/59239) ([Raúl Marín](https://github.com/Algunenano)).
+
+#### Performance Improvement
+* Primary key will use less amount of memory. [#60049](https://github.com/ClickHouse/ClickHouse/pull/60049) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Improve memory usage for primary key and some other operations. [#60050](https://github.com/ClickHouse/ClickHouse/pull/60050) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* The tables' primary keys will be loaded in memory lazily on first access. This is controlled by the new MergeTree setting `primary_key_lazy_load`, which is on by default. This provides several advantages: - it will not be loaded for tables that are not used; - if there is not enough memory, an exception will be thrown on first use instead of at server startup. This provides several disadvantages: - the latency of loading the primary key will be paid on the first query rather than before accepting connections; this theoretically may introduce a thundering-herd problem. This closes [#11188](https://github.com/ClickHouse/ClickHouse/issues/11188). [#60093](https://github.com/ClickHouse/ClickHouse/pull/60093) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Vectorized distance functions used in vector search. [#58866](https://github.com/ClickHouse/ClickHouse/pull/58866) ([Robert Schulze](https://github.com/rschu1ze)).
+* Vectorized function `dotProduct` which is useful for vector search. [#60202](https://github.com/ClickHouse/ClickHouse/pull/60202) ([Robert Schulze](https://github.com/rschu1ze)).
+* Add short-circuit ability for `dictGetOrDefault` function. Closes [#52098](https://github.com/ClickHouse/ClickHouse/issues/52098). [#57767](https://github.com/ClickHouse/ClickHouse/pull/57767) ([jsc0218](https://github.com/jsc0218)).
+* Keeper improvement: cache only a certain amount of logs in-memory controlled by `latest_logs_cache_size_threshold` and `commit_logs_cache_size_threshold`. [#59460](https://github.com/ClickHouse/ClickHouse/pull/59460) ([Antonio Andelic](https://github.com/antonio2368)).
+* Keeper improvement: reduce size of data node even more. [#59592](https://github.com/ClickHouse/ClickHouse/pull/59592) ([Antonio Andelic](https://github.com/antonio2368)).
+* Continue optimizing branch miss of `if` function when result type is `Float*/Decimal*/*Int*`, follow up of https://github.com/ClickHouse/ClickHouse/pull/57885. [#59148](https://github.com/ClickHouse/ClickHouse/pull/59148) ([李扬](https://github.com/taiyang-li)).
+* Optimize `if` function when the input type is `Map`, the speed-up is up to ~10x. [#59413](https://github.com/ClickHouse/ClickHouse/pull/59413) ([李扬](https://github.com/taiyang-li)).
+* Improve performance of the `Int8` type by implementing strict aliasing (we already have it for `UInt8` and all other integer types). [#59485](https://github.com/ClickHouse/ClickHouse/pull/59485) ([Raúl Marín](https://github.com/Algunenano)).
+* Optimize performance of sum/avg conditionally for bigint and big decimal types by reducing branch miss. [#59504](https://github.com/ClickHouse/ClickHouse/pull/59504) ([李扬](https://github.com/taiyang-li)).
+* Improve performance of SELECTs with active mutations. [#59531](https://github.com/ClickHouse/ClickHouse/pull/59531) ([Azat Khuzhin](https://github.com/azat)).
+* Optimized function `isNotNull` with AVX2. [#59621](https://github.com/ClickHouse/ClickHouse/pull/59621) ([李扬](https://github.com/taiyang-li)).
+* Improve ASOF JOIN performance for sorted or almost sorted data. [#59731](https://github.com/ClickHouse/ClickHouse/pull/59731) ([Maksim Kita](https://github.com/kitaisreal)).
+* The previous default value equals to 1 MB for `async_insert_max_data_size` appeared to be too small. The new one would be 10 MiB. [#59536](https://github.com/ClickHouse/ClickHouse/pull/59536) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Use multiple threads while reading the metadata of tables from a backup while executing the RESTORE command. [#60040](https://github.com/ClickHouse/ClickHouse/pull/60040) ([Vitaly Baranov](https://github.com/vitlibar)).
+* Now if `StorageBuffer` has more than 1 shard (`num_layers` > 1) background flush will happen simultaneously for all shards in multiple threads. [#60111](https://github.com/ClickHouse/ClickHouse/pull/60111) ([alesapin](https://github.com/alesapin)).
+
+#### Improvement
+* When output format is `Pretty` format and a block consists of a single numeric value which exceeds one million, A readable number will be printed on table right. [#60379](https://github.com/ClickHouse/ClickHouse/pull/60379) ([rogeryk](https://github.com/rogeryk)).
+* Added settings `split_parts_ranges_into_intersecting_and_non_intersecting_final` and `split_intersecting_parts_ranges_into_layers_final`. These settings are needed to disable optimizations for queries with `FINAL` and needed for debug only. [#59705](https://github.com/ClickHouse/ClickHouse/pull/59705) ([Maksim Kita](https://github.com/kitaisreal)). Actually not only for that - they can also lower memory usage at the expense of performance.
+* Rename the setting `extract_kvp_max_pairs_per_row` to `extract_key_value_pairs_max_pairs_per_row`. The issue (unnecessary abbreviation in the setting name) was introduced in https://github.com/ClickHouse/ClickHouse/pull/43606. Fix the documentation of this setting. [#59683](https://github.com/ClickHouse/ClickHouse/pull/59683) ([Alexey Milovidov](https://github.com/alexey-milovidov)). [#59960](https://github.com/ClickHouse/ClickHouse/pull/59960) ([jsc0218](https://github.com/jsc0218)).
+* Running `ALTER COLUMN MATERIALIZE` on a column with `DEFAULT` or `MATERIALIZED` expression now precisely follows the semantics. [#58023](https://github.com/ClickHouse/ClickHouse/pull/58023) ([Duc Canh Le](https://github.com/canhld94)).
+* Enabled an exponential backoff logic for errors during mutations. It will reduce the CPU usage, memory usage and log file sizes. [#58036](https://github.com/ClickHouse/ClickHouse/pull/58036) ([MikhailBurdukov](https://github.com/MikhailBurdukov)).
+* Add improvement to count the `InitialQuery` Profile Event. [#58195](https://github.com/ClickHouse/ClickHouse/pull/58195) ([Unalian](https://github.com/Unalian)).
+* Allow to define `volume_priority` in `storage_configuration`. [#58533](https://github.com/ClickHouse/ClickHouse/pull/58533) ([Andrey Zvonov](https://github.com/zvonand)).
+* Add support for the `Date32` type in the `T64` codec. [#58738](https://github.com/ClickHouse/ClickHouse/pull/58738) ([Hongbin Ma](https://github.com/binmahone)).
+* Allow trailing commas in types with several items. [#59119](https://github.com/ClickHouse/ClickHouse/pull/59119) ([Aleksandr Musorin](https://github.com/AVMusorin)).
+* Settings for the Distributed table engine can now be specified in the server configuration file (similar to MergeTree settings), e.g. `<distributed> <flush_on_detach>false</flush_on_detach> </distributed>`. [#59291](https://github.com/ClickHouse/ClickHouse/pull/59291) ([Azat Khuzhin](https://github.com/azat)).
+* Retry disconnects and expired sessions when reading `system.zookeeper`. This is helpful when reading many rows from `system.zookeeper` table especially in the presence of fault-injected disconnects. [#59388](https://github.com/ClickHouse/ClickHouse/pull/59388) ([Alexander Gololobov](https://github.com/davenger)).
+* Do not interpret numbers with leading zeroes as octals when `input_format_values_interpret_expressions=0`. [#59403](https://github.com/ClickHouse/ClickHouse/pull/59403) ([Joanna Hulboj](https://github.com/jh0x)).
+* At startup and whenever config files are changed, ClickHouse updates the hard memory limits of its total memory tracker. These limits are computed based on various server settings and cgroups limits (on Linux). Previously, setting `/sys/fs/cgroup/memory.max` (for cgroups v2) was hard-coded. As a result, cgroup v2 memory limits configured for nested groups (hierarchies), e.g. `/sys/fs/cgroup/my/nested/group/memory.max` were ignored. This is now fixed. The behavior of v1 memory limits remains unchanged. [#59435](https://github.com/ClickHouse/ClickHouse/pull/59435) ([Robert Schulze](https://github.com/rschu1ze)).
+* New profile events added to observe the time spent on calculating PK/projections/secondary indices during `INSERT`-s. [#59436](https://github.com/ClickHouse/ClickHouse/pull/59436) ([Nikita Taranov](https://github.com/nickitat)).
+* Allow to define a starting point for S3Queue with Ordered mode at the creation using a setting `s3queue_last_processed_path`. [#59446](https://github.com/ClickHouse/ClickHouse/pull/59446) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Made comments for system tables also available in `system.tables` in `clickhouse-local`. [#59493](https://github.com/ClickHouse/ClickHouse/pull/59493) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* `system.zookeeper` table: previously the whole result was accumulated in memory and returned as one big chunk. This change should help to reduce memory consumption when reading many rows from `system.zookeeper`, allow showing intermediate progress (how many rows have been read so far) and avoid hitting connection timeout when result set is big. [#59545](https://github.com/ClickHouse/ClickHouse/pull/59545) ([Alexander Gololobov](https://github.com/davenger)).
+* Now dashboard understands both compressed and uncompressed state of URL's #hash (backward compatibility). Continuation of [#59124](https://github.com/ClickHouse/ClickHouse/issues/59124) . [#59548](https://github.com/ClickHouse/ClickHouse/pull/59548) ([Amos Bird](https://github.com/amosbird)).
+* Bumped Intel QPL (used by codec `DEFLATE_QPL`) from v1.3.1 to v1.4.0 . Also fixed a bug for polling timeout mechanism, as we observed in same cases timeout won't work properly, if timeout happen, IAA and CPU may process buffer concurrently. So far, we'd better make sure IAA codec status is not QPL_STS_BEING_PROCESSED, then fallback to SW codec. [#59551](https://github.com/ClickHouse/ClickHouse/pull/59551) ([jasperzhu](https://github.com/jinjunzh)).
+* Do not show a warning about the server version in ClickHouse Cloud because ClickHouse Cloud handles seamless upgrades automatically. [#59657](https://github.com/ClickHouse/ClickHouse/pull/59657) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* After self-extraction temporary binary is moved instead copying. [#59661](https://github.com/ClickHouse/ClickHouse/pull/59661) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
+* Fix stack unwinding on Apple macOS. This closes [#53653](https://github.com/ClickHouse/ClickHouse/issues/53653). [#59690](https://github.com/ClickHouse/ClickHouse/pull/59690) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Check for stack overflow in parsers even if the user misconfigured the `max_parser_depth` setting to a very high value. This closes [#59622](https://github.com/ClickHouse/ClickHouse/issues/59622). [#59697](https://github.com/ClickHouse/ClickHouse/pull/59697) ([Alexey Milovidov](https://github.com/alexey-milovidov)). [#60434](https://github.com/ClickHouse/ClickHouse/pull/60434)
+* Unify XML and SQL created named collection behaviour in Kafka storage. [#59710](https://github.com/ClickHouse/ClickHouse/pull/59710) ([Pervakov Grigorii](https://github.com/GrigoryPervakov)).
+* In case when `merge_max_block_size_bytes` is small enough and tables contain wide rows (strings or tuples) background merges may stuck in an endless loop. This behaviour is fixed. Follow-up for https://github.com/ClickHouse/ClickHouse/pull/59340. [#59812](https://github.com/ClickHouse/ClickHouse/pull/59812) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Allow uuid in replica_path if CREATE TABLE explicitly has it. [#59908](https://github.com/ClickHouse/ClickHouse/pull/59908) ([Azat Khuzhin](https://github.com/azat)).
+* Add column `metadata_version` of ReplicatedMergeTree table in `system.tables` system table. [#59942](https://github.com/ClickHouse/ClickHouse/pull/59942) ([Maksim Kita](https://github.com/kitaisreal)).
+* Keeper improvement: send only Keeper related metrics/events for Prometheus. [#59945](https://github.com/ClickHouse/ClickHouse/pull/59945) ([Antonio Andelic](https://github.com/antonio2368)).
+* The dashboard will display metrics across different ClickHouse versions even if the structure of system tables has changed after the upgrade. [#59967](https://github.com/ClickHouse/ClickHouse/pull/59967) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Allow loading AZ info from a file. [#59976](https://github.com/ClickHouse/ClickHouse/pull/59976) ([Konstantin Bogdanov](https://github.com/thevar1able)).
+* Keeper improvement: add retries on failures for Disk related operations. [#59980](https://github.com/ClickHouse/ClickHouse/pull/59980) ([Antonio Andelic](https://github.com/antonio2368)).
+* Add new config setting `backups.remove_backup_files_after_failure`: `<clickhouse> <backups> <remove_backup_files_after_failure>true</remove_backup_files_after_failure> </backups> </clickhouse>`. [#60002](https://github.com/ClickHouse/ClickHouse/pull/60002) ([Vitaly Baranov](https://github.com/vitlibar)).
+* Copy S3 file GCP fallback to buffer copy in case GCP returned `Internal Error` with `GATEWAY_TIMEOUT` HTTP error code. [#60164](https://github.com/ClickHouse/ClickHouse/pull/60164) ([Maksim Kita](https://github.com/kitaisreal)).
+* Short circuit execution for `ULIDStringToDateTime`. [#60211](https://github.com/ClickHouse/ClickHouse/pull/60211) ([Juan Madurga](https://github.com/jlmadurga)).
+* Added `query_id` column for tables `system.backups` and `system.backup_log`. Added error stacktrace to `error` column. [#60220](https://github.com/ClickHouse/ClickHouse/pull/60220) ([Maksim Kita](https://github.com/kitaisreal)).
+* Connections through the MySQL port now automatically run with setting `prefer_column_name_to_alias = 1` to support QuickSight out-of-the-box. Also, settings `mysql_map_string_to_text_in_show_columns` and `mysql_map_fixed_string_to_text_in_show_columns` are now enabled by default, affecting also only MySQL connections. This increases compatibility with more BI tools. [#60365](https://github.com/ClickHouse/ClickHouse/pull/60365) ([Robert Schulze](https://github.com/rschu1ze)).
+* Fix a race condition in JavaScript code leading to duplicate charts on top of each other. [#60392](https://github.com/ClickHouse/ClickHouse/pull/60392) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+
+#### Build/Testing/Packaging Improvement
+* Added builds and tests with coverage collection with introspection. Continuation of [#56102](https://github.com/ClickHouse/ClickHouse/issues/56102). [#58792](https://github.com/ClickHouse/ClickHouse/pull/58792) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Update the Rust toolchain in `corrosion-cmake` when the CMake cross-compilation toolchain variable is set. [#59309](https://github.com/ClickHouse/ClickHouse/pull/59309) ([Aris Tritas](https://github.com/aris-aiven)).
+* Add some fuzzing to ASTLiterals. [#59383](https://github.com/ClickHouse/ClickHouse/pull/59383) ([Raúl Marín](https://github.com/Algunenano)).
+* If you want to run initdb scripts every time when ClickHouse container is starting you shoud initialize environment varible CLICKHOUSE_ALWAYS_RUN_INITDB_SCRIPTS. [#59808](https://github.com/ClickHouse/ClickHouse/pull/59808) ([Alexander Nikolaev](https://github.com/AlexNik)).
+* Remove ability to disable generic clickhouse components (like server/client/...), but keep some that requires extra libraries (like ODBC or keeper). [#59857](https://github.com/ClickHouse/ClickHouse/pull/59857) ([Azat Khuzhin](https://github.com/azat)).
+* Query fuzzer will fuzz SETTINGS inside queries. [#60087](https://github.com/ClickHouse/ClickHouse/pull/60087) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Add support for building ClickHouse with clang-19 (master). [#60448](https://github.com/ClickHouse/ClickHouse/pull/60448) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+
+#### Bug Fix (user-visible misbehavior in an official stable release)

+### ClickHouse release v24.2.1.2248-stable (891689a4150) FIXME as compared to v24.1.1.2048-stable (5a024dfc093)
+
+#### Backward Incompatible Change
+* Validate suspicious/experimental types in nested types. Previously we didn't validate such types (except JSON) in nested types like Array/Tuple/Map. [#59385](https://github.com/ClickHouse/ClickHouse/pull/59385) ([Kruglov Pavel](https://github.com/Avogar)).
+* The sort clause `ORDER BY ALL` (introduced with v23.12) is replaced by `ORDER BY *`. The previous syntax was too error-prone for tables with a column `all`. [#59450](https://github.com/ClickHouse/ClickHouse/pull/59450) ([Robert Schulze](https://github.com/rschu1ze)).
+* Rename the setting `extract_kvp_max_pairs_per_row` to `extract_key_value_pairs_max_pairs_per_row`. The bug (unnecessary abbreviation in the setting name) was introduced in https://github.com/ClickHouse/ClickHouse/pull/43606. Fix the documentation of this setting. [#59683](https://github.com/ClickHouse/ClickHouse/pull/59683) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Rename the setting extract_kvp_max_pairs_per_row to extract_key_value_pairs_max_pairs_per_row. The bug (unnecessary abbreviation in the setting name) was introduced in https://github.com/ClickHouse/ClickHouse/pull/43606. Fix the documentation of this setting. [#59960](https://github.com/ClickHouse/ClickHouse/pull/59960) ([jsc0218](https://github.com/jsc0218)).
+* Add sanity check for number of threads and block sizes. [#60138](https://github.com/ClickHouse/ClickHouse/pull/60138) ([Raúl Marín](https://github.com/Algunenano)).
+
+#### New Feature
+* Added maximum sequential login failures to the quota. [#54737](https://github.com/ClickHouse/ClickHouse/pull/54737) ([Alexey Gerasimchuck](https://github.com/Demilivor)).
+* Added new syntax which allows to specify definer user in View/Materialized View. This allows to execute selects/inserts from views without explicit grants for underlying tables. [#54901](https://github.com/ClickHouse/ClickHouse/pull/54901) ([pufit](https://github.com/pufit)).
+* Backup & Restore support for AzureBlobStorage resolves [#50747](https://github.com/ClickHouse/ClickHouse/issues/50747). [#56988](https://github.com/ClickHouse/ClickHouse/pull/56988) ([SmitaRKulkarni](https://github.com/SmitaRKulkarni)).
+* Implemented automatic conversion of merge tree tables of different kinds to replicated engine. Create empty `convert_to_replicated` file in table's data directory (`/clickhouse/store/xxx/xxxyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy/`) and that table will be converted automatically on next server start. [#57798](https://github.com/ClickHouse/ClickHouse/pull/57798) ([Kirill](https://github.com/kirillgarbar)).
+* Added table function `mergeTreeIndex`. It represents the contents of index and marks files of `MergeTree` tables. It can be used for introspection. Syntax: `mergeTreeIndex(database, table, [with_marks = true])` where `database.table` is an existing table with `MergeTree` engine. [#58140](https://github.com/ClickHouse/ClickHouse/pull/58140) ([Anton Popov](https://github.com/CurtizJ)).
+* Added function `seriesOutliersTukey` to detect outliers in series data using Tukey's fences algorithm. [#58632](https://github.com/ClickHouse/ClickHouse/pull/58632) ([Bhavna Jindal](https://github.com/bhavnajindal)).
+* The user can now specify the template string directly in the query using `format_schema_rows_template` as an alternative to `format_template_row`. Closes [#31363](https://github.com/ClickHouse/ClickHouse/issues/31363). [#59088](https://github.com/ClickHouse/ClickHouse/pull/59088) ([Shaun Struwig](https://github.com/Blargian)).
+* Try to detect file format automatically during schema inference if it's unknown in `file/s3/hdfs/url/azureBlobStorage` engines. Closes [#50576](https://github.com/ClickHouse/ClickHouse/issues/50576). [#59092](https://github.com/ClickHouse/ClickHouse/pull/59092) ([Kruglov Pavel](https://github.com/Avogar)).
+* Add function variantType that returns Enum with variant type name for each row. [#59398](https://github.com/ClickHouse/ClickHouse/pull/59398) ([Kruglov Pavel](https://github.com/Avogar)).
+* Added query `ALTER TABLE table FORGET PARTITION partition` that removes ZooKeeper nodes, related to an empty partition. [#59507](https://github.com/ClickHouse/ClickHouse/pull/59507) ([Sergei Trifonov](https://github.com/serxa)).
+* Support JWT credentials file for the NATS table engine. [#59543](https://github.com/ClickHouse/ClickHouse/pull/59543) ([Nickolaj Jepsen](https://github.com/nickolaj-jepsen)).
+* Provides new aggregate function ‘groupArrayIntersect’. Follows up: [#49862](https://github.com/ClickHouse/ClickHouse/issues/49862). [#59598](https://github.com/ClickHouse/ClickHouse/pull/59598) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
+* Implemented system.dns_cache table, which can be useful for debugging DNS issues. [#59856](https://github.com/ClickHouse/ClickHouse/pull/59856) ([Kirill Nikiforov](https://github.com/allmazz)).
+* The codec `LZ4HC` will accept a new level 2, which is faster than the previous minimum level 3, at the expense of less compression. In previous versions, `LZ4HC(2)` and less was the same as `LZ4HC(3)`. Author: [Cyan4973](https://github.com/Cyan4973). [#60090](https://github.com/ClickHouse/ClickHouse/pull/60090) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Implemented system.dns_cache table, which can be useful for debugging DNS issues. New server setting dns_cache_max_size. [#60257](https://github.com/ClickHouse/ClickHouse/pull/60257) ([Kirill Nikiforov](https://github.com/allmazz)).
+* Support single-argument version for the merge table function, as `merge(['db_name', ] 'tables_regexp')`. [#60372](https://github.com/ClickHouse/ClickHouse/pull/60372) ([豪肥肥](https://github.com/HowePa)).
+* Added new syntax which allows to specify definer user in View/Materialized View. This allows to execute selects/inserts from views without explicit grants for underlying tables. [#60439](https://github.com/ClickHouse/ClickHouse/pull/60439) ([pufit](https://github.com/pufit)).
+
+#### Performance Improvement
+* Eliminates min/max/any/anyLast aggregators of GROUP BY keys in SELECT section. [#52230](https://github.com/ClickHouse/ClickHouse/pull/52230) ([JackyWoo](https://github.com/JackyWoo)).
+* Vectorized distance functions used in vector search. [#58866](https://github.com/ClickHouse/ClickHouse/pull/58866) ([Robert Schulze](https://github.com/rschu1ze)).
+* Continue optimizing branch miss of if function when result type is float*/decimal*/int* , follow up of https://github.com/ClickHouse/ClickHouse/pull/57885. [#59148](https://github.com/ClickHouse/ClickHouse/pull/59148) ([李扬](https://github.com/taiyang-li)).
+* Optimize if function when input type is map, speed up by ~10x. [#59413](https://github.com/ClickHouse/ClickHouse/pull/59413) ([李扬](https://github.com/taiyang-li)).
+* Improve performance of Int8 type by implementing strict aliasing. [#59485](https://github.com/ClickHouse/ClickHouse/pull/59485) ([Raúl Marín](https://github.com/Algunenano)).
+* Optimize performance of sum/avg conditionally for bigint and big decimal types by reducing branch miss. [#59504](https://github.com/ClickHouse/ClickHouse/pull/59504) ([李扬](https://github.com/taiyang-li)).
+* Improve performance of SELECTs with active mutations. [#59531](https://github.com/ClickHouse/ClickHouse/pull/59531) ([Azat Khuzhin](https://github.com/azat)).
+* Optimized function `isNotNull` with AVX2. [#59621](https://github.com/ClickHouse/ClickHouse/pull/59621) ([李扬](https://github.com/taiyang-li)).
+* Reuse the result of `FunctionFactory::instance().get("isNotNull", context)` and `FunctionFactory::instance().get("assumeNotNull", context)`. Make sure it is called once during the lifetime of `FunctionCoalesce`. [#59627](https://github.com/ClickHouse/ClickHouse/pull/59627) ([李扬](https://github.com/taiyang-li)).
+* Improve ASOF JOIN performance for sorted or almost sorted data. [#59731](https://github.com/ClickHouse/ClickHouse/pull/59731) ([Maksim Kita](https://github.com/kitaisreal)).
+* Primary key will use less amount of memory. [#60049](https://github.com/ClickHouse/ClickHouse/pull/60049) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Improve memory usage for primary key and some other operations. [#60050](https://github.com/ClickHouse/ClickHouse/pull/60050) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* The tables' primary keys will be loaded in memory lazily on first access. This is controlled by the new MergeTree setting `primary_key_lazy_load`, which is on by default. This provides several advantages: - it will not be loaded for tables that are not used; - if there is not enough memory, an exception will be thrown on first use instead of at server startup. This provides several disadvantages: - the latency of loading the primary key will be paid on the first query rather than before accepting connections; this theoretically may introduce a thundering-herd problem. This closes [#11188](https://github.com/ClickHouse/ClickHouse/issues/11188). [#60093](https://github.com/ClickHouse/ClickHouse/pull/60093) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Vectorized function `dotProduct` which is useful for vector search. [#60202](https://github.com/ClickHouse/ClickHouse/pull/60202) ([Robert Schulze](https://github.com/rschu1ze)).
+* As is shown in Fig 1, the replacement of "&&" with "&" could generate the SIMD code. ![image](https://github.com/ClickHouse/ClickHouse/assets/26588299/a5a72ac4-6dc6-4d52-835a-4f512e55f0b9) Fig 1. Code compiled from '&&' (left) and '&' (right). [#60498](https://github.com/ClickHouse/ClickHouse/pull/60498) ([Zhiguo Zhou](https://github.com/ZhiguoZh)).
+
+#### Improvement
+* Added support for parameterized view with analyzer to not analyze create parameterized view. Refactor existing parameterized view logic to not analyze create parameterized view. [#54211](https://github.com/ClickHouse/ClickHouse/pull/54211) ([SmitaRKulkarni](https://github.com/SmitaRKulkarni)).
+* Do not consider data part as broken if projection is broken. Closes [#56593](https://github.com/ClickHouse/ClickHouse/issues/56593). [#56864](https://github.com/ClickHouse/ClickHouse/pull/56864) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Add short-circuit ability for `dictGetOrDefault` function. Closes [#52098](https://github.com/ClickHouse/ClickHouse/issues/52098). [#57767](https://github.com/ClickHouse/ClickHouse/pull/57767) ([jsc0218](https://github.com/jsc0218)).
+* Running `ALTER COLUMN MATERIALIZE` on a column with `DEFAULT` or `MATERIALIZED` expression now writes the correct values: The default value for existing parts with default value or the non-default value for existing parts with non-default value. Previously, the default value was written for all existing parts. [#58023](https://github.com/ClickHouse/ClickHouse/pull/58023) ([Duc Canh Le](https://github.com/canhld94)).
+* Enabled a backoff logic (e.g. exponential). Will provide an ability for reduced CPU usage, memory usage and log file sizes. [#58036](https://github.com/ClickHouse/ClickHouse/pull/58036) ([MikhailBurdukov](https://github.com/MikhailBurdukov)).
+* Add improvement to count InitialQuery. [#58195](https://github.com/ClickHouse/ClickHouse/pull/58195) ([Unalian](https://github.com/Unalian)).
+* Support negative positional arguments. Closes [#57736](https://github.com/ClickHouse/ClickHouse/issues/57736). [#58292](https://github.com/ClickHouse/ClickHouse/pull/58292) ([flynn](https://github.com/ucasfl)).
+* Implement auto-adjustment for asynchronous insert timeouts. The following settings are introduced: async_insert_poll_timeout_ms, async_insert_use_adaptive_busy_timeout, async_insert_busy_timeout_min_ms, async_insert_busy_timeout_max_ms, async_insert_busy_timeout_increase_rate, async_insert_busy_timeout_decrease_rate. [#58486](https://github.com/ClickHouse/ClickHouse/pull/58486) ([Julia Kartseva](https://github.com/jkartseva)).
+* Allow to define `volume_priority` in `storage_configuration`. [#58533](https://github.com/ClickHouse/ClickHouse/pull/58533) ([Andrey Zvonov](https://github.com/zvonand)).
+* Add support for Date32 type in T64 codec. [#58738](https://github.com/ClickHouse/ClickHouse/pull/58738) ([Hongbin Ma](https://github.com/binmahone)).
+* Support `LEFT JOIN`, `ALL INNER JOIN`, and simple subqueries for parallel replicas (only with analyzer). New setting `parallel_replicas_prefer_local_join` chooses local `JOIN` execution (by default) vs `GLOBAL JOIN`. All tables should exist on every replica from `cluster_for_parallel_replicas`. New settings `min_external_table_block_size_rows` and `min_external_table_block_size_bytes` are used to squash small blocks that are sent for temporary tables (only with analyzer). [#58916](https://github.com/ClickHouse/ClickHouse/pull/58916) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
+* Allow trailing commas in types with several items. [#59119](https://github.com/ClickHouse/ClickHouse/pull/59119) ([Aleksandr Musorin](https://github.com/AVMusorin)).
+* Allow parallel and distributed processing for `S3Queue` table engine. For distributed processing use setting `s3queue_total_shards_num` (by default `1`). Setting `s3queue_processing_threads_num` previously was not allowed for Ordered processing mode, now it is allowed. Warning: settings `s3queue_processing_threads_num`(processing threads per each shard) and `s3queue_total_shards_num` for ordered mode change how metadata is stored (make the number of `max_processed_file` nodes equal to `s3queue_processing_threads_num * s3queue_total_shards_num`), so they must be the same for all shards and cannot be changed once at least one shard is created. [#59167](https://github.com/ClickHouse/ClickHouse/pull/59167) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Allow concurrent table creation in `DatabaseReplicated` during `recoverLostReplica`. [#59277](https://github.com/ClickHouse/ClickHouse/pull/59277) ([Konstantin Bogdanov](https://github.com/thevar1able)).
+* Settings for the Distributed table engine can now be specified in the server configuration file (similar to MergeTree settings), e.g. ``` <distributed> <flush_on_detach>false</flush_on_detach> </distributed> ```. [#59291](https://github.com/ClickHouse/ClickHouse/pull/59291) ([Azat Khuzhin](https://github.com/azat)).
+* Use MergeTree as a default table engine. It makes the usability much better, and closer to ClickHouse Cloud. [#59316](https://github.com/ClickHouse/ClickHouse/pull/59316) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Retry disconnects and expired sessions when reading `system.zookeeper`. This is helpful when reading many rows from `system.zookeeper` table especially in the presence of fault-injected disconnects. [#59388](https://github.com/ClickHouse/ClickHouse/pull/59388) ([Alexander Gololobov](https://github.com/davenger)).
+* Do not interpret numbers with leading zeroes as octals when `input_format_values_interpret_expressions=0`. [#59403](https://github.com/ClickHouse/ClickHouse/pull/59403) ([Joanna Hulboj](https://github.com/jh0x)).
+* At startup and whenever config files are changed, ClickHouse updates the hard memory limits of its total memory tracker. These limits are computed based on various server settings and cgroups limits (on Linux). Previously, setting `/sys/fs/cgroup/memory.max` (for cgroups v2) was hard-coded. As a result, cgroup v2 memory limits configured for nested groups (hierarchies), e.g. `/sys/fs/cgroup/my/nested/group/memory.max` were ignored. This is now fixed. The behavior of v1 memory limits remains unchanged. [#59435](https://github.com/ClickHouse/ClickHouse/pull/59435) ([Robert Schulze](https://github.com/rschu1ze)).
+* New profile events added to observe the time spent on calculating PK/projections/secondary indices during `INSERT`-s. [#59436](https://github.com/ClickHouse/ClickHouse/pull/59436) ([Nikita Taranov](https://github.com/nickitat)).
+* Allow to define a starting point for S3Queue with Ordered mode at creation using setting `s3queue_last_processed_path`. [#59446](https://github.com/ClickHouse/ClickHouse/pull/59446) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Keeper improvement: cache only a certain amount of logs in-memory controlled by `latest_logs_cache_size_threshold` and `commit_logs_cache_size_threshold`. [#59460](https://github.com/ClickHouse/ClickHouse/pull/59460) ([Antonio Andelic](https://github.com/antonio2368)).
+* Made comments for system tables also available in `system.tables` in `clickhouse-local`. [#59493](https://github.com/ClickHouse/ClickHouse/pull/59493) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Don't infer floats in exponential notation by default. Add a setting `input_format_try_infer_exponent_floats` that will restore previous behaviour (disabled by default). Closes [#59476](https://github.com/ClickHouse/ClickHouse/issues/59476). [#59500](https://github.com/ClickHouse/ClickHouse/pull/59500) ([Kruglov Pavel](https://github.com/Avogar)).
+* Allow alter operations to be surrounded by parenthesis. The emission of parentheses can be controlled by the `format_alter_operations_with_parentheses` config. By default in formatted queries the parentheses are emitted as we store the formatted alter operations in some places as metadata (e.g.: mutations). The new syntax clarifies some of the queries where alter operations end in a list. E.g.: `ALTER TABLE x MODIFY TTL date GROUP BY a, b, DROP COLUMN c` cannot be parsed properly with the old syntax. In the new syntax the query `ALTER TABLE x (MODIFY TTL date GROUP BY a, b), (DROP COLUMN c)` is obvious. Older versions are not able to read the new syntax, therefore using the new syntax might cause issues if newer and older version of ClickHouse are mixed in a single cluster. [#59532](https://github.com/ClickHouse/ClickHouse/pull/59532) ([János Benjamin Antal](https://github.com/antaljanosbenjamin)).
+* The previous default value equals to 1 MB for `async_insert_max_data_size` appeared to be too small. The new one would be 10 MiB. [#59536](https://github.com/ClickHouse/ClickHouse/pull/59536) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Previously the whole result was accumulated in memory and returned as one big chunk. This change should help to reduce memory consumption when reading many rows from `system.zookeeper`, allow showing intermediate progress (how many rows have been read so far) and avoid hitting connection timeout when result set is big. [#59545](https://github.com/ClickHouse/ClickHouse/pull/59545) ([Alexander Gololobov](https://github.com/davenger)).
+* Now dashboard understands both compressed and uncompressed state of URL's #hash (backward compatibility). Continuation of [#59124](https://github.com/ClickHouse/ClickHouse/issues/59124) . [#59548](https://github.com/ClickHouse/ClickHouse/pull/59548) ([Amos Bird](https://github.com/amosbird)).
+* Bumped Intel QPL (used by codec `DEFLATE_QPL`) from v1.3.1 to v1.4.0 . Also fixed a bug for polling timeout mechanism, as we observed in same cases timeout won't work properly, if timeout happen, IAA and CPU may process buffer concurrently. So far, we'd better make sure IAA codec status is not QPL_STS_BEING_PROCESSED, then fallback to SW codec. [#59551](https://github.com/ClickHouse/ClickHouse/pull/59551) ([jasperzhu](https://github.com/jinjunzh)).
+* Keeper improvement: reduce size of data node even more. [#59592](https://github.com/ClickHouse/ClickHouse/pull/59592) ([Antonio Andelic](https://github.com/antonio2368)).
+* Do not show a warning about the server version in ClickHouse Cloud because ClickHouse Cloud handles seamless upgrades automatically. [#59657](https://github.com/ClickHouse/ClickHouse/pull/59657) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* After self-extraction temporary binary is moved instead copying. [#59661](https://github.com/ClickHouse/ClickHouse/pull/59661) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
+* Fix stack unwinding on MacOS. This closes [#53653](https://github.com/ClickHouse/ClickHouse/issues/53653). [#59690](https://github.com/ClickHouse/ClickHouse/pull/59690) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Check for stack overflow in parsers even if the user misconfigured the `max_parser_depth` setting to a very high value. This closes [#59622](https://github.com/ClickHouse/ClickHouse/issues/59622). [#59697](https://github.com/ClickHouse/ClickHouse/pull/59697) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Perform synchronous inserts if dependent MV deduplication is enabled through deduplicate_blocks_in_dependent_materialized_views=1. [#59699](https://github.com/ClickHouse/ClickHouse/pull/59699) ([Julia Kartseva](https://github.com/jkartseva)).
+* Added settings `split_parts_ranges_into_intersecting_and_non_intersecting_final` and `split_intersecting_parts_ranges_into_layers_final`. This settings are needed to disable optimizations for queries with `FINAL` and needed for debug only. [#59705](https://github.com/ClickHouse/ClickHouse/pull/59705) ([Maksim Kita](https://github.com/kitaisreal)).
+* Unify xml and sql created named collection behaviour in kafka storage. [#59710](https://github.com/ClickHouse/ClickHouse/pull/59710) ([Pervakov Grigorii](https://github.com/GrigoryPervakov)).
+* In case when `merge_max_block_size_bytes` is small enough and tables contain wide rows (strings or tuples) background merges may stuck in an endless loop. This behaviour is fixed. Follow-up for https://github.com/ClickHouse/ClickHouse/pull/59340. [#59812](https://github.com/ClickHouse/ClickHouse/pull/59812) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Allow uuid in replica_path if CREATE TABLE explicitly has it. [#59908](https://github.com/ClickHouse/ClickHouse/pull/59908) ([Azat Khuzhin](https://github.com/azat)).
+* Add column `metadata_version` of ReplicatedMergeTree table in `system.tables` system table. [#59942](https://github.com/ClickHouse/ClickHouse/pull/59942) ([Maksim Kita](https://github.com/kitaisreal)).
+* Keeper improvement: send only Keeper related metrics/events for Prometheus. [#59945](https://github.com/ClickHouse/ClickHouse/pull/59945) ([Antonio Andelic](https://github.com/antonio2368)).
+* The dashboard will display metrics across different ClickHouse versions even if the structure of system tables has changed after the upgrade. [#59967](https://github.com/ClickHouse/ClickHouse/pull/59967) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Allow loading AZ info from a file. [#59976](https://github.com/ClickHouse/ClickHouse/pull/59976) ([Konstantin Bogdanov](https://github.com/thevar1able)).
+* Keeper improvement: add retries on failures for Disk related operations. [#59980](https://github.com/ClickHouse/ClickHouse/pull/59980) ([Antonio Andelic](https://github.com/antonio2368)).
+* Add new config setting `backups.remove_backup_files_after_failure`: ``` <clickhouse> <backups> <remove_backup_files_after_failure>true</remove_backup_files_after_failure> </backups> </clickhouse> ```. [#60002](https://github.com/ClickHouse/ClickHouse/pull/60002) ([Vitaly Baranov](https://github.com/vitlibar)).
+* Use multiple threads while reading the metadata of tables from a backup while executing the RESTORE command. [#60040](https://github.com/ClickHouse/ClickHouse/pull/60040) ([Vitaly Baranov](https://github.com/vitlibar)).
+* Now if `StorageBuffer` has more than 1 shard (`num_layers` > 1) background flush will happen simultaneously for all shards in multiple threads. [#60111](https://github.com/ClickHouse/ClickHouse/pull/60111) ([alesapin](https://github.com/alesapin)).
+* Support specifying users for specific S3 settings in config using `user` key. [#60144](https://github.com/ClickHouse/ClickHouse/pull/60144) ([Antonio Andelic](https://github.com/antonio2368)).
+* Copy S3 file GCP fallback to buffer copy in case GCP returned `Internal Error` with `GATEWAY_TIMEOUT` HTTP error code. [#60164](https://github.com/ClickHouse/ClickHouse/pull/60164) ([Maksim Kita](https://github.com/kitaisreal)).
+* Implement comparison operator for Variant values and proper Field inserting into Variant column. Don't allow creating `Variant` type with similar variant types by default (allow uder a setting `allow_suspicious_variant_types`) Closes [#59996](https://github.com/ClickHouse/ClickHouse/issues/59996). Closes [#59850](https://github.com/ClickHouse/ClickHouse/issues/59850). [#60198](https://github.com/ClickHouse/ClickHouse/pull/60198) ([Kruglov Pavel](https://github.com/Avogar)).
+* Short circuit execution for `ULIDStringToDateTime`. [#60211](https://github.com/ClickHouse/ClickHouse/pull/60211) ([Juan Madurga](https://github.com/jlmadurga)).
+* Added `query_id` column for tables `system.backups` and `system.backup_log`. Added error stacktrace to `error` column. [#60220](https://github.com/ClickHouse/ClickHouse/pull/60220) ([Maksim Kita](https://github.com/kitaisreal)).
+* Connections through the MySQL port now automatically run with setting `prefer_column_name_to_alias = 1` to support QuickSight out-of-the-box. Also, settings `mysql_map_string_to_text_in_show_columns` and `mysql_map_fixed_string_to_text_in_show_columns` are now enabled by default, affecting also only MySQL connections. This increases compatibility with more BI tools. [#60365](https://github.com/ClickHouse/ClickHouse/pull/60365) ([Robert Schulze](https://github.com/rschu1ze)).
+* When output format is Pretty format and a block consists of a single numeric value which exceeds one million, A readable number will be printed on table right. e.g. ``` ┌──────count()─┐ │ 233765663884 │ -- 233.77 billion └──────────────┘ ```. [#60379](https://github.com/ClickHouse/ClickHouse/pull/60379) ([rogeryk](https://github.com/rogeryk)).
+* Fix a race condition in JavaScript code leading to duplicate charts on top of each other. [#60392](https://github.com/ClickHouse/ClickHouse/pull/60392) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Check for stack overflow in parsers even if the user misconfigured the `max_parser_depth` setting to a very high value. This closes [#59622](https://github.com/ClickHouse/ClickHouse/issues/59622). [#60434](https://github.com/ClickHouse/ClickHouse/pull/60434) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+
+#### Build/Testing/Packaging Improvement
+* Added builds and tests with coverage collection with introspection. Continuation of [#56102](https://github.com/ClickHouse/ClickHouse/issues/56102). [#58792](https://github.com/ClickHouse/ClickHouse/pull/58792) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Include `pytest-reportlog` in integration test CI runner Dockerfile to enable JSON test reports. [#58926](https://github.com/ClickHouse/ClickHouse/pull/58926) ([MyroTk](https://github.com/MyroTk)).
+* Update the rust toolchain in `corrosion-cmake` when the CMake cross-compilation toolchain variable is set. [#59309](https://github.com/ClickHouse/ClickHouse/pull/59309) ([Aris Tritas](https://github.com/aris-aiven)).
+* Add some fuzzing to ASTLiterals. [#59383](https://github.com/ClickHouse/ClickHouse/pull/59383) ([Raúl Marín](https://github.com/Algunenano)).
+* If you want to run initdb scripts every time when ClickHouse container is starting you shoud initialize environment varible CLICKHOUSE_ALWAYS_RUN_INITDB_SCRIPTS. [#59808](https://github.com/ClickHouse/ClickHouse/pull/59808) ([Alexander Nikolaev](https://github.com/AlexNik)).
+* Remove ability to disable generic clickhouse components (like server/client/...), but keep some that requires extra libraries (like ODBC or keeper). [#59857](https://github.com/ClickHouse/ClickHouse/pull/59857) ([Azat Khuzhin](https://github.com/azat)).

 :::note
 The ClickHouse cluster consists of independent shards, and each shard consists of replicas. The cluster is **not elastic**, so after adding a new shard, data is not rebalanced between shards automatically. Instead, the cluster load is supposed to be adjusted to be uneven. This implementation gives you more control, and it is ok for relatively small clusters, such as tens of nodes. But for clusters with hundreds of nodes that we are using in production, this approach becomes a significant drawback. We should implement a table engine that spans across the cluster with dynamically replicated regions that could be split and balanced between clusters automatically.

+## Using in-memory cache (userspace page cache) {#userspace-page-cache}
+
+The File Cache described above stores cached data in local files. Alternatively, object-store-based disks can be configured to use "Userspace Page Cache", which is RAM-only. Userspace page cache is recommended only if file cache can't be used for some reason, e.g. if the machine doesn't have a local disk at all. Note that file cache effectively uses RAM for caching too, since the OS caches contents of local files.
+
+To enable userspace page cache for disks that don't use file cache, use setting `use_page_cache_for_disks_without_file_cache`.
+
+By default, on Linux, the userspace page cache will use all available memory, similar to the OS page cache. In tools like `top` and `ps`, the clickhouse server process will typically show resident set size near 100% of the machine's RAM - this is normal, and most of this memory is actually reclaimable by the OS on memory pressure (`MADV_FREE`). This behavior can be disabled with server setting `page_cache_use_madv_free = 0`, making the userspace page cache just use a fixed amount of memory `page_cache_size` with no special interaction with the OS. On Mac OS, `page_cache_use_madv_free` is always disabled as it doesn't have lazy `MADV_FREE`.
+
+Unfortunately, `page_cache_use_madv_free` makes it difficult to tell if the server is close to running out of memory, since the RSS metric becomes useless. Async metric `UnreclaimableRSS` shows the amount of physical memory used by the server, excluding the memory reclaimable by the OS: `select value from system.asynchronous_metrics where metric = 'UnreclaimableRSS'`. Use it for monitoring instead of RSS. This metric is only available if `page_cache_use_madv_free` is enabled.
+
 ## Storing Data on Web Server {#storing-data-on-webserver}
 
 There is a tool `clickhouse-static-files-uploader`, which prepares a data directory for a given table (`SELECT data_paths FROM system.tables WHERE name = 'table_name'`). For each table you need, you get a directory of files. These files can be uploaded to, for example, a web server with static files. After this preparation, you can load this table into any ClickHouse server via `DiskWeb`.

 ### Parameters
 
 There are 4 customizable parameters. They are passed to the function sequentially, but there is no need to pass all four - default values will be used, however good model required some parameter tuning.

-4.  `method for updating weights`, they are: `Adam` (by default), `SGD`, `Momentum`, `Nesterov`. `Momentum` and `Nesterov` require little bit more computations and memory, however they happen to be useful in terms of speed of convergence and stability of stochastic gradient methods.

 ### Usage
 
-`stochasticLinearRegression` is used in two steps: fitting the model and predicting on new data. In order to fit the model and save its state for later usage we use `-State` combinator, which basically saves the state (model weights, etc).
-To predict we use function [evalMLMethod](../../../sql-reference/functions/machine-learning-functions.md#machine_learning_methods-evalmlmethod), which takes a state as an argument as well as features to predict on.

 Note that using `select_sequential_consistency` will increase the load on ClickHouse Keeper (used by ClickHouse Cloud internally) and may result in slower performance depending on the load on the service. We recommend against enabling this setting unless necessary. The recommended approach is to execute read/writes in the same session or to use a client driver that uses the native protocol (and thus supports sticky connections).

+
+In a replicated setup, data will be visible on other replicas after it has been replicated. Data begins being replicated (downloaded on other replicas) immediately after an `INSERT`. This differs from ClickHouse Cloud, where data is immediately written to shared storage and replicas subscribe to metadata changes.

+It is possible to asynchronously insert data in small but frequent inserts. The data from such insertions is combined into batches and then safely inserted into a table. To use asynchronous inserts, enable the [`async_insert`](../../operations/settings/settings.md#async-insert) setting.

+Using `async_insert` or the [`Buffer` table engine](/en/engines/table-engines/special/buffer) results in additional buffering.

+### Large or long-running inserts
+
+When you are inserting large amounts of data, ClickHouse will optimize write performance through a process called "squashing". Small blocks of inserted data in memory are merged and squashed into larger blocks before being written to disk. Squashing reduces the overhead associated with each write operation. In this process, inserted data will be available to query after ClickHouse completes writing each [`max_insert_block_size`](/en/operations/settings/settings#max_insert_block_size) rows.
