 # 2024 Changelog
 
+### <a id="246"></a> ClickHouse release 24.6, 2024-07-01
+
+#### Backward Incompatible Change
+* Enable asynchronous load of databases and tables by default. See the `async_load_databases` in config.xml. While this change is fully compatible, it can introduce a difference in behavior. When `async_load_databases` is false, as in the previous versions, the server will not accept connections until all tables are loaded. When `async_load_databases` is true, as in the new version, the server can accept connections before all the tables are loaded. If a query is made to a table that is not yet loaded, it will wait for the table's loading, which can take considerable time. It can change the behavior of the server if it is part of a large distributed system under a load balancer. In the first case, the load balancer can get a connection refusal and quickly failover to another server. In the second case, the load balancer can connect to a server that is still loading the tables, and the query will have a higher latency. Moreover, if many queries accumulate in the waiting state, it can lead to a "thundering herd" problem when they start processing simultaneously. This can make a difference only for highly loaded distributed backends. You can set the value of `async_load_databases` to false to avoid this problem. [#57695](https://github.com/ClickHouse/ClickHouse/pull/57695) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Setting `replace_long_file_name_to_hash` is enabled by default for `MergeTree` tables. [#64457](https://github.com/ClickHouse/ClickHouse/pull/64457) ([Anton Popov](https://github.com/CurtizJ)). This setting is fully compatible, and no actions needed during upgrade. The new data format is supported from all versions starting from 23.9. After enabling this setting, you can no longer downgrade to a version 23.8 or older.
+* Some invalid queries will fail earlier during parsing. Note: disabled the support for inline KQL expressions (the experimental Kusto language) when they are put into a `kql` table function without a string literal, e.g. `kql(garbage | trash)` instead of `kql('garbage | trash')` or `kql($$garbage | trash$$)`. This feature was introduced unintentionally and should not exist. [#61500](https://github.com/ClickHouse/ClickHouse/pull/61500) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Rework parallel processing in `Ordered` mode of storage `S3Queue`. This PR is backward incompatible for Ordered mode if you used settings `s3queue_processing_threads_num` or `s3queue_total_shards_num`. Setting `s3queue_total_shards_num` is deleted, previously it was allowed to use only under `s3queue_allow_experimental_sharded_mode`, which is now deprecated. A new setting is added - `s3queue_buckets`. [#64349](https://github.com/ClickHouse/ClickHouse/pull/64349) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* New functions `snowflakeIDToDateTime`, `snowflakeIDToDateTime64`, `dateTimeToSnowflakeID`, and `dateTime64ToSnowflakeID` were added. Unlike the existing functions `snowflakeToDateTime`, `snowflakeToDateTime64`, `dateTimeToSnowflake`, and `dateTime64ToSnowflake`, the new functions are compatible with function `generateSnowflakeID`, i.e. they accept the snowflake IDs generated by `generateSnowflakeID` and produce snowflake IDs of the same type as `generateSnowflakeID` (i.e. `UInt64`). Furthermore, the new functions default to the UNIX epoch (aka. 1970-01-01), just like `generateSnowflakeID`. If necessary, a different epoch, e.g. Twitter's/X's epoch 2010-11-04 aka. 1288834974657 msec since UNIX epoch, can be passed. The old conversion functions are deprecated and will be removed after a transition period: to use them regardless, enable setting `allow_deprecated_snowflake_conversion_functions`. [#64948](https://github.com/ClickHouse/ClickHouse/pull/64948) ([Robert Schulze](https://github.com/rschu1ze)).

+* Added a new table function `loop` to support returning query results in an infinite loop. [#63452](https://github.com/ClickHouse/ClickHouse/pull/63452) ([Sariel](https://github.com/sarielwxm)). This is useful for testing.
+* Introduced two additional columns in the `system.query_log`: `used_privileges` and `missing_privileges`. `used_privileges` is populated with the privileges that were checked during query execution, and `missing_privileges` contains required privileges that are missing. [#64597](https://github.com/ClickHouse/ClickHouse/pull/64597) ([Alexey Katsman](https://github.com/alexkats)).
+* Added a setting `output_format_pretty_display_footer_column_names` which when enabled displays column names at the end of the table for long tables (50 rows by default), with the threshold value for minimum number of rows controlled by `output_format_pretty_display_footer_column_names_min_rows`. [#65144](https://github.com/ClickHouse/ClickHouse/pull/65144) ([Shaun Struwig](https://github.com/Blargian)).

+* Add settings `parallel_replicas_custom_key_range_lower` and `parallel_replicas_custom_key_range_upper` to control how parallel replicas with dynamic shards parallelizes queries when using a range filter. [#64604](https://github.com/ClickHouse/ClickHouse/pull/64604) ([josh-hildred](https://github.com/josh-hildred)).
+
+#### Performance Improvement
+* Add the ability to reshuffle rows during insert to optimize for size without violating the order set by `PRIMARY KEY`. It's controlled by the setting `optimize_row_order` (off by default). [#63578](https://github.com/ClickHouse/ClickHouse/pull/63578) ([Igor Markelov](https://github.com/ElderlyPassionFruit)).
+* Add a native parquet reader, which can read parquet binary to ClickHouse Columns directly. It's controlled by the setting `input_format_parquet_use_native_reader` (disabled by default). [#60361](https://github.com/ClickHouse/ClickHouse/pull/60361) ([ZhiHong Zhang](https://github.com/copperybean)).

+* Added a new setting, `metadata_keep_free_space_bytes` to keep free space on the metadata storage disk. [#64128](https://github.com/ClickHouse/ClickHouse/pull/64128) ([MikhailBurdukov](https://github.com/MikhailBurdukov)).
+* Add metrics to track the number of directories created and removed by the `plain_rewritable` metadata storage, and the number of entries in the local-to-remote in-memory map. [#64175](https://github.com/ClickHouse/ClickHouse/pull/64175) ([Julia Kartseva](https://github.com/jkartseva)).
+* The query cache now considers identical queries with different settings as different. This increases robustness in cases where different settings (e.g. `limit` or `additional_table_filters`) would affect the query result. [#64205](https://github.com/ClickHouse/ClickHouse/pull/64205) ([Robert Schulze](https://github.com/rschu1ze)).
+* Support the non standard error code `QpsLimitExceeded` in object storage as a retryable error. [#64225](https://github.com/ClickHouse/ClickHouse/pull/64225) ([Sema Checherinda](https://github.com/CheSema)).
+* Forbid converting a MergeTree table to replicated if the zookeeper path for this table already exists. [#64244](https://github.com/ClickHouse/ClickHouse/pull/64244) ([Kirill](https://github.com/kirillgarbar)).
+* Added a new setting `input_format_parquet_prefer_block_bytes` to control the average output block bytes, and modified the default value of `input_format_parquet_max_block_size` to 65409. [#64427](https://github.com/ClickHouse/ClickHouse/pull/64427) ([LiuNeng](https://github.com/liuneng1994)).

+* Always start Keeper with sufficient amount of threads in global thread pool. [#64444](https://github.com/ClickHouse/ClickHouse/pull/64444) ([Duc Canh Le](https://github.com/canhld94)).
+* Settings from the user's config don't affect merges and mutations for `MergeTree` on top of object storage. [#64456](https://github.com/ClickHouse/ClickHouse/pull/64456) ([alesapin](https://github.com/alesapin)).
+* Support the non standard error code `TotalQpsLimitExceeded` in object storage as a retryable error. [#64520](https://github.com/ClickHouse/ClickHouse/pull/64520) ([Sema Checherinda](https://github.com/CheSema)).
+* Updated Advanced Dashboard for both open-source and ClickHouse Cloud versions to include a chart for 'Maximum concurrent network connections'. [#64610](https://github.com/ClickHouse/ClickHouse/pull/64610) ([Thom O'Connor](https://github.com/thomoco)).
+* Improve progress report on `zeros_mt` and `generateRandom`. [#64804](https://github.com/ClickHouse/ClickHouse/pull/64804) ([Raúl Marín](https://github.com/Algunenano)).
+* Add an asynchronous metric `jemalloc.profile.active` to show whether sampling is currently active. This is an activation mechanism in addition to prof.active; both must be active for the calling thread to sample. [#64842](https://github.com/ClickHouse/ClickHouse/pull/64842) ([Unalian](https://github.com/Unalian)).
+* Remove mark of `allow_experimental_join_condition` as important. This mark may have prevented distributed queries in a mixed versions cluster from being executed successfully. [#65008](https://github.com/ClickHouse/ClickHouse/pull/65008) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Added server Asynchronous metrics `DiskGetObjectThrottler*` and `DiskGetObjectThrottler*` reflecting request per second rate limit defined with `s3_max_get_rps` and `s3_max_put_rps` disk settings and currently available number of requests that could be sent without hitting throttling limit on the disk. Metrics are defined for every disk that has a configured limit. [#65050](https://github.com/ClickHouse/ClickHouse/pull/65050) ([Sergei Trifonov](https://github.com/serxa)).
+* Initialize global trace collector for `Poco::ThreadPool` (needed for Keeper, etc). [#65239](https://github.com/ClickHouse/ClickHouse/pull/65239) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Add a validation when creating a user with `bcrypt_hash`. [#65242](https://github.com/ClickHouse/ClickHouse/pull/65242) ([Raúl Marín](https://github.com/Algunenano)).

+* Rename `allow_deprecated_functions` to `allow_deprecated_error_prone_window_functions`. [#64358](https://github.com/ClickHouse/ClickHouse/pull/64358) ([Raúl Marín](https://github.com/Algunenano)).
+* Respect `max_read_buffer_size` setting for file descriptors as well in the `file` table function. [#64532](https://github.com/ClickHouse/ClickHouse/pull/64532) ([Azat Khuzhin](https://github.com/azat)).
+* Disable transactions for unsupported storages even for materialized views. [#64918](https://github.com/ClickHouse/ClickHouse/pull/64918) ([alesapin](https://github.com/alesapin)).
+* Forbid `QUALIFY` clause in the old analyzer. The old analyzer ignored `QUALIFY`, so it could lead to unexpected data removal in mutations. [#65356](https://github.com/ClickHouse/ClickHouse/pull/65356) ([Dmitry Novik](https://github.com/novikd)).
+
+#### Bug Fix (user-visible misbehavior in an official stable release)

+* Returned back the behaviour of how ClickHouse works and interprets Tuples in CSV format. This change effectively reverts https://github.com/ClickHouse/ClickHouse/pull/60994 and makes it available only under a few settings: `output_format_csv_serialize_tuple_into_separate_columns`, `input_format_csv_deserialize_separate_columns_into_tuple` and `input_format_csv_try_infer_strings_from_quoted_tuples`. [#65170](https://github.com/ClickHouse/ClickHouse/pull/65170) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).

+* Use correct memory alignment for Distinct combinator. Previously, crash could happen because of invalid memory allocation when the combinator was used. [#65379](https://github.com/ClickHouse/ClickHouse/pull/65379) ([Antonio Andelic](https://github.com/antonio2368)).
+* Fix crash with `DISTINCT` and window functions. [#64767](https://github.com/ClickHouse/ClickHouse/pull/64767) ([Igor Nikonov](https://github.com/devcrafter)).
+* Fixed 'set' skip index not working with IN and indexHint(). [#62083](https://github.com/ClickHouse/ClickHouse/pull/62083) ([Michael Kolupaev](https://github.com/al13n321)).
+* Support executing function during assignment of parameterized view value. [#63502](https://github.com/ClickHouse/ClickHouse/pull/63502) ([SmitaRKulkarni](https://github.com/SmitaRKulkarni)).

+* This fix will use a proper redefined context with the correct definer for each individual view in the query pipeline. [#64079](https://github.com/ClickHouse/ClickHouse/pull/64079) ([pufit](https://github.com/pufit)).
+* Fix analyzer: "Not found column" error is fixed when using INTERPOLATE. [#64096](https://github.com/ClickHouse/ClickHouse/pull/64096) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
+* Fix creating backups to S3 buckets with different credentials from the disk containing the file. [#64153](https://github.com/ClickHouse/ClickHouse/pull/64153) ([Antonio Andelic](https://github.com/antonio2368)).
+* The query cache now considers two identical queries against different databases as different. The previous behavior could be used to bypass missing privileges to read from a table. [#64199](https://github.com/ClickHouse/ClickHouse/pull/64199) ([Robert Schulze](https://github.com/rschu1ze)).

+* Fix the output of function `formatDateTimeInJodaSyntax` when a formatter generates an uneven number of characters and the last character is `0`. For example, `SELECT formatDateTimeInJodaSyntax(toDate('2012-05-29'), 'D')` now correctly returns `150` instead of previously `15`. [#64614](https://github.com/ClickHouse/ClickHouse/pull/64614) ([LiuNeng](https://github.com/liuneng1994)).
+* Do not rewrite aggregation if `-If` combinator is already used. [#64638](https://github.com/ClickHouse/ClickHouse/pull/64638) ([Dmitry Novik](https://github.com/novikd)).
+* Fix type inference for float (in case of small buffer, i.e. `--max_read_buffer_size 1`). [#64641](https://github.com/ClickHouse/ClickHouse/pull/64641) ([Azat Khuzhin](https://github.com/azat)).

+* This PR ensures that the type of the constant(IN operator's second parameter) is always visible during the IN operator's type conversion process. Otherwise, losing type information may cause some conversions to fail, such as the conversion from DateTime to Date. This fixes ([#64487](https://github.com/ClickHouse/ClickHouse/issues/64487)). [#65315](https://github.com/ClickHouse/ClickHouse/pull/65315) ([pn](https://github.com/chloro-pn)).
+
+#### Build/Testing/Packaging Improvement
+* Add support for LLVM XRay. [#64592](https://github.com/ClickHouse/ClickHouse/pull/64592) [#64837](https://github.com/ClickHouse/ClickHouse/pull/64837) ([Tomer Shafir](https://github.com/tomershafir)).
+* Unite s3/hdfs/azure storage implementations into a single class working with IObjectStorage. Same for *Cluster, data lakes and Queue storages. [#59767](https://github.com/ClickHouse/ClickHouse/pull/59767) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Refactor data part writer to remove dependencies on MergeTreeData and DataPart. [#63620](https://github.com/ClickHouse/ClickHouse/pull/63620) ([Alexander Gololobov](https://github.com/davenger)).
+* Refactor `KeyCondition` and key analysis to improve PartitionPruner and trivial count optimization. This is separated from [#60463](https://github.com/ClickHouse/ClickHouse/issues/60463) . [#61459](https://github.com/ClickHouse/ClickHouse/pull/61459) ([Amos Bird](https://github.com/amosbird)).
+* Introduce assertions to verify all functions are called with columns of the right size. [#63723](https://github.com/ClickHouse/ClickHouse/pull/63723) ([Raúl Marín](https://github.com/Algunenano)).
+* Make `network` service be required when using the `rc` init script to start the ClickHouse server daemon. [#60650](https://github.com/ClickHouse/ClickHouse/pull/60650) ([Chun-Sheng, Li](https://github.com/peter279k)).
+* Reduce the size of some slow tests. [#64387](https://github.com/ClickHouse/ClickHouse/pull/64387) [#64452](https://github.com/ClickHouse/ClickHouse/pull/64452) ([Raúl Marín](https://github.com/Algunenano)).
+* Replay ZooKeeper logs using keeper-bench. [#62481](https://github.com/ClickHouse/ClickHouse/pull/62481) ([Antonio Andelic](https://github.com/antonio2368)).
+
+### <a id="245"></a> ClickHouse release 24.5, 2024-05-30
+
+#### Backward Incompatible Change
+* Renamed "inverted indexes" to "full-text indexes" which is a less technical / more user-friendly name. This also changes internal table metadata and breaks tables with existing (experimental) inverted indexes. Please make sure to drop such indexes before upgrade and re-create them after upgrade. [#62884](https://github.com/ClickHouse/ClickHouse/pull/62884) ([Robert Schulze](https://github.com/rschu1ze)).
+* Usage of functions `neighbor`, `runningAccumulate`, `runningDifferenceStartingWithFirstValue`, `runningDifference` deprecated (because it is error-prone). Proper window functions should be used instead. To enable them back, set `allow_deprecated_error_prone_window_functions = 1` or set `compatibility = '24.4'` or lower. [#63132](https://github.com/ClickHouse/ClickHouse/pull/63132) ([Nikita Taranov](https://github.com/nickitat)).
+* Queries from `system.columns` will work faster if there is a large number of columns, but many databases or tables are not granted for `SHOW TABLES`. Note that in previous versions, if you grant `SHOW COLUMNS` to individual columns without granting `SHOW TABLES` to the corresponding tables, the `system.columns` table will show these columns, but in a new version, it will skip the table entirely. Remove trace log messages "Access granted" and "Access denied" that slowed down queries. [#63439](https://github.com/ClickHouse/ClickHouse/pull/63439) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+
+#### New Feature
+* Adds the `Form` format to read/write a single record in the `application/x-www-form-urlencoded` format. [#60199](https://github.com/ClickHouse/ClickHouse/pull/60199) ([Shaun Struwig](https://github.com/Blargian)).
+* Added possibility to compress in CROSS JOIN. [#60459](https://github.com/ClickHouse/ClickHouse/pull/60459) ([p1rattttt](https://github.com/p1rattttt)).
+* Added possibility to do `CROSS JOIN` in temporary files if the size exceeds limits. [#63432](https://github.com/ClickHouse/ClickHouse/pull/63432) ([p1rattttt](https://github.com/p1rattttt)).
+* Support join with inequal conditions which involve columns from both left and right table. e.g. `t1.y < t2.y`. To enable, `SET allow_experimental_join_condition = 1`. [#60920](https://github.com/ClickHouse/ClickHouse/pull/60920) ([lgbo](https://github.com/lgbo-ustc)).
+* Maps can now have `Float32`, `Float64`, `Array(T)`, `Map(K, V)` and `Tuple(T1, T2, ...)` as keys. Closes [#54537](https://github.com/ClickHouse/ClickHouse/issues/54537). [#59318](https://github.com/ClickHouse/ClickHouse/pull/59318) ([李扬](https://github.com/taiyang-li)).
+* Introduce bulk loading to `EmbeddedRocksDB` by creating and ingesting SST file instead of relying on rocksdb build-in memtable. This help to increase importing speed, especially for long-running insert query to StorageEmbeddedRocksDB tables. Also, introduce `EmbeddedRocksDB` table settings. [#59163](https://github.com/ClickHouse/ClickHouse/pull/59163) [#63324](https://github.com/ClickHouse/ClickHouse/pull/63324) ([Duc Canh Le](https://github.com/canhld94)).
+* User can now parse CRLF with TSV format using a setting `input_format_tsv_crlf_end_of_line`. Closes [#56257](https://github.com/ClickHouse/ClickHouse/issues/56257). [#59747](https://github.com/ClickHouse/ClickHouse/pull/59747) ([Shaun Struwig](https://github.com/Blargian)).
+* A new setting `input_format_force_null_for_omitted_fields` that forces NULL values for omitted fields. [#60887](https://github.com/ClickHouse/ClickHouse/pull/60887) ([Constantine Peresypkin](https://github.com/pkit)).
+* Earlier our S3 storage and s3 table function didn't support selecting from archive container files, such as tarballs, zip, 7z. Now they allow to iterate over files inside archives in S3. [#62259](https://github.com/ClickHouse/ClickHouse/pull/62259) ([Daniil Ivanik](https://github.com/divanik)).
+* Support for conditional function `clamp`. [#62377](https://github.com/ClickHouse/ClickHouse/pull/62377) ([skyoct](https://github.com/skyoct)).
+* Add `NPy` output format. [#62430](https://github.com/ClickHouse/ClickHouse/pull/62430) ([豪肥肥](https://github.com/HowePa)).
+* `Raw` format as a synonym for `TSVRaw`. [#63394](https://github.com/ClickHouse/ClickHouse/pull/63394) ([Unalian](https://github.com/Unalian)).
+* Added a new SQL function `generateUUIDv7` to generate version 7 UUIDs aka. timestamp-based UUIDs with random component. Also added a new function `UUIDToNum` to extract bytes from a UUID and a new function `UUIDv7ToDateTime` to extract timestamp component from a UUID version 7. [#62852](https://github.com/ClickHouse/ClickHouse/pull/62852) ([Alexey Petrunyaka](https://github.com/pet74alex)).
+* On Linux and MacOS, if the program has stdout redirected to a file with a compression extension, use the corresponding compression method instead of nothing (making it behave similarly to `INTO OUTFILE`). [#63662](https://github.com/ClickHouse/ClickHouse/pull/63662) ([v01dXYZ](https://github.com/v01dXYZ)).
+* Change warning on high number of attached tables to differentiate tables, views and dictionaries. [#64180](https://github.com/ClickHouse/ClickHouse/pull/64180) ([Francisco J. Jurado Moreno](https://github.com/Beetelbrox)).
+* Provide support for `azureBlobStorage` function in ClickHouse server to use Azure Workload identity to authenticate against Azure blob storage. If `use_workload_identity` parameter is set in config, [workload identity](https://github.com/Azure/azure-sdk-for-cpp/tree/main/sdk/identity/azure-identity#authenticate-azure-hosted-applications) is used for authentication. [#57881](https://github.com/ClickHouse/ClickHouse/pull/57881) ([Vinay Suryadevara](https://github.com/vinay92-ch)).
+* Add TTL information in the `system.parts_columns` table. [#63200](https://github.com/ClickHouse/ClickHouse/pull/63200) ([litlig](https://github.com/litlig)).
+
+#### Experimental Features
+* Implement `Dynamic` data type that allows to store values of any type inside it without knowing all of them in advance. `Dynamic` type is available under a setting `allow_experimental_dynamic_type`. Reference: [#54864](https://github.com/ClickHouse/ClickHouse/issues/54864). [#63058](https://github.com/ClickHouse/ClickHouse/pull/63058) ([Kruglov Pavel](https://github.com/Avogar)).
+* Allowed to create `MaterializedMySQL` database without connection to MySQL. [#63397](https://github.com/ClickHouse/ClickHouse/pull/63397) ([Kirill](https://github.com/kirillgarbar)).
+* Automatically mark a replica of Replicated database as lost and start recovery if some DDL task fails more than `max_retries_before_automatic_recovery` (100 by default) times in a row with the same error. Also, fixed a bug that could cause skipping DDL entries when an exception is thrown during an early stage of entry execution. [#63549](https://github.com/ClickHouse/ClickHouse/pull/63549) ([Alexander Tokmakov](https://github.com/tavplubix)).
+* Account failed files in `s3queue_tracked_file_ttl_sec` and `s3queue_traked_files_limit` for `StorageS3Queue`. [#63638](https://github.com/ClickHouse/ClickHouse/pull/63638) ([Kseniia Sumarokova](https://github.com/kssenii)).
+
+#### Performance Improvement
+* Less contention in filesystem cache (part 4). Allow to keep filesystem cache not filled to the limit by doing additional eviction in the background (controlled by `keep_free_space_size(elements)_ratio`). This allows to release pressure from space reservation for queries (on `tryReserve` method). Also this is done in a lock free way as much as possible, e.g. should not block normal cache usage. [#61250](https://github.com/ClickHouse/ClickHouse/pull/61250) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Skip merging of newly created projection blocks during `INSERT`-s. [#59405](https://github.com/ClickHouse/ClickHouse/pull/59405) ([Nikita Taranov](https://github.com/nickitat)).
+* Process string functions `...UTF8` 'asciily' if input strings are all ascii chars. Inspired by https://github.com/apache/doris/pull/29799. Overall speed up by 1.07x~1.62x. Notice that peak memory usage had been decreased in some cases. [#61632](https://github.com/ClickHouse/ClickHouse/pull/61632) ([李扬](https://github.com/taiyang-li)).
+* Improved performance of selection (`{}`) globs in StorageS3. [#62120](https://github.com/ClickHouse/ClickHouse/pull/62120) ([Andrey Zvonov](https://github.com/zvonand)).
+* HostResolver has each IP address several times. If remote host has several IPs and by some reason (firewall rules for example) access on some IPs allowed and on others forbidden, than only first record of forbidden IPs marked as failed, and in each try these IPs have a chance to be chosen (and failed again). Even if fix this, every 120 seconds DNS cache dropped, and IPs can be chosen again. [#62652](https://github.com/ClickHouse/ClickHouse/pull/62652) ([Anton Ivashkin](https://github.com/ianton-ru)).
+* Add a new configuration`prefer_merge_sort_block_bytes` to control the memory usage and speed up sorting 2 times when merging when there are many columns. [#62904](https://github.com/ClickHouse/ClickHouse/pull/62904) ([LiuNeng](https://github.com/liuneng1994)).
+* `clickhouse-local` will start faster. In previous versions, it was not deleting temporary directories by mistake. Now it will. This closes [#62941](https://github.com/ClickHouse/ClickHouse/issues/62941). [#63074](https://github.com/ClickHouse/ClickHouse/pull/63074) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Micro-optimizations for the new analyzer. [#63429](https://github.com/ClickHouse/ClickHouse/pull/63429) ([Raúl Marín](https://github.com/Algunenano)).
+* Index analysis will work if `DateTime` is compared to `DateTime64`. This closes [#63441](https://github.com/ClickHouse/ClickHouse/issues/63441). [#63443](https://github.com/ClickHouse/ClickHouse/pull/63443) [#63532](https://github.com/ClickHouse/ClickHouse/pull/63532) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Speed up indices of type `set` a little (around 1.5 times) by removing garbage. [#64098](https://github.com/ClickHouse/ClickHouse/pull/64098) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Remove copying data when writing to the filesystem cache. [#63401](https://github.com/ClickHouse/ClickHouse/pull/63401) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Now backups with azure blob storage will use multicopy. [#64116](https://github.com/ClickHouse/ClickHouse/pull/64116) ([alesapin](https://github.com/alesapin)).
+* Allow to use native copy for azure even with different containers. [#64154](https://github.com/ClickHouse/ClickHouse/pull/64154) ([alesapin](https://github.com/alesapin)).
+* Finally enable native copy for azure. [#64182](https://github.com/ClickHouse/ClickHouse/pull/64182) ([alesapin](https://github.com/alesapin)).
+
+#### Improvement
+* Allow using `clickhouse-local` and its shortcuts `clickhouse` and `ch` with a query or queries file as a positional argument. Examples: `ch "SELECT 1"`, `ch --param_test Hello "SELECT {test:String}"`, `ch query.sql`. This closes [#62361](https://github.com/ClickHouse/ClickHouse/issues/62361). [#63081](https://github.com/ClickHouse/ClickHouse/pull/63081) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Enable plain_rewritable metadata for local and Azure (azure_blob_storage) object storages. [#63365](https://github.com/ClickHouse/ClickHouse/pull/63365) ([Julia Kartseva](https://github.com/jkartseva)).
+* Support English-style Unicode quotes, e.g. “Hello”, ‘world’. This is questionable in general but helpful when you type your query in a word processor, such as Google Docs. This closes [#58634](https://github.com/ClickHouse/ClickHouse/issues/58634). [#63381](https://github.com/ClickHouse/ClickHouse/pull/63381) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Allow trailing commas in the columns list in the INSERT query. For example, `INSERT INTO test (a, b, c, ) VALUES ...`. [#63803](https://github.com/ClickHouse/ClickHouse/pull/63803) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Better exception messages for the `Regexp` format. [#63804](https://github.com/ClickHouse/ClickHouse/pull/63804) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Allow trailing commas in the `Values` format. For example, this query is allowed: `INSERT INTO test (a, b, c) VALUES (4, 5, 6,);`. [#63810](https://github.com/ClickHouse/ClickHouse/pull/63810) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Make rabbitmq nack broken messages. Closes [#45350](https://github.com/ClickHouse/ClickHouse/issues/45350). [#60312](https://github.com/ClickHouse/ClickHouse/pull/60312) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Fix a crash in asynchronous stack unwinding (such as when using the sampling query profiler) while interpreting debug info. This closes [#60460](https://github.com/ClickHouse/ClickHouse/issues/60460). [#60468](https://github.com/ClickHouse/ClickHouse/pull/60468) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Distinct messages for s3 error 'no key' for cases disk and storage. [#61108](https://github.com/ClickHouse/ClickHouse/pull/61108) ([Sema Checherinda](https://github.com/CheSema)).
+* The progress bar will work for trivial queries with LIMIT from `system.zeros`, `system.zeros_mt` (it already works for `system.numbers` and `system.numbers_mt`), and the `generateRandom` table function. As a bonus, if the total number of records is greater than the `max_rows_to_read` limit, it will throw an exception earlier. This closes [#58183](https://github.com/ClickHouse/ClickHouse/issues/58183). [#61823](https://github.com/ClickHouse/ClickHouse/pull/61823) ([Alexey Milovidov](https://github.com/alexey-milovidov)).

+
+### <a id="244"></a> ClickHouse release 24.4, 2024-04-30
+
+#### Upgrade Notes
+* `clickhouse-odbc-bridge` and `clickhouse-library-bridge` are now separate packages. This closes [#61677](https://github.com/ClickHouse/ClickHouse/issues/61677). [#62114](https://github.com/ClickHouse/ClickHouse/pull/62114) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Don't allow to set max_parallel_replicas (for the experimental parallel reading from replicas) to `0` as it doesn't make sense. Closes [#60140](https://github.com/ClickHouse/ClickHouse/issues/60140). [#61201](https://github.com/ClickHouse/ClickHouse/pull/61201) ([Kruglov Pavel](https://github.com/Avogar)).
+* Remove support for `INSERT WATCH` query (part of the deprecated `LIVE VIEW` feature). [#62382](https://github.com/ClickHouse/ClickHouse/pull/62382) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Removed the `optimize_monotonous_functions_in_order_by` setting. [#63004](https://github.com/ClickHouse/ClickHouse/pull/63004) ([Raúl Marín](https://github.com/Algunenano)).
+* Remove experimental tag from the `Replicated` database engine. Now it is in Beta stage. [#62937](https://github.com/ClickHouse/ClickHouse/pull/62937) ([Justin de Guzman](https://github.com/justindeguzman)).
+
+#### New Feature
+* Support recursive CTEs. [#62074](https://github.com/ClickHouse/ClickHouse/pull/62074) ([Maksim Kita](https://github.com/kitaisreal)).
+* Support `QUALIFY` clause. Closes [#47819](https://github.com/ClickHouse/ClickHouse/issues/47819). [#62619](https://github.com/ClickHouse/ClickHouse/pull/62619) ([Maksim Kita](https://github.com/kitaisreal)).
+* Table engines are grantable now, and it won't affect existing users behavior. [#60117](https://github.com/ClickHouse/ClickHouse/pull/60117) ([jsc0218](https://github.com/jsc0218)).
+* Added a rewritable S3 disk which supports INSERT operations and does not require locally stored metadata. [#61116](https://github.com/ClickHouse/ClickHouse/pull/61116) ([Julia Kartseva](https://github.com/jkartseva)). The main use case is for system tables.
+* The syntax highlighting while typing in the client will work on the syntax level (previously, it worked on the lexer level). [#62123](https://github.com/ClickHouse/ClickHouse/pull/62123) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Supports dropping multiple tables at the same time like `DROP TABLE a, b, c`;. [#58705](https://github.com/ClickHouse/ClickHouse/pull/58705) ([zhongyuankai](https://github.com/zhongyuankai)).
+* Modifying memory table settings through `ALTER MODIFY SETTING` is now supported. Example: `ALTER TABLE memory MODIFY SETTING min_rows_to_keep = 100, max_rows_to_keep = 1000;`. [#62039](https://github.com/ClickHouse/ClickHouse/pull/62039) ([zhongyuankai](https://github.com/zhongyuankai)).
+* Added `role` query parameter to the HTTP interface. It works similarly to `SET ROLE x`, applying the role before the statement is executed. This allows for overcoming the limitation of the HTTP interface, as multiple statements are not allowed, and it is not possible to send both `SET ROLE x` and the statement itself at the same time. It is possible to set multiple roles that way, e.g., `?role=x&role=y`, which will be an equivalent of `SET ROLE x, y`. [#62669](https://github.com/ClickHouse/ClickHouse/pull/62669) ([Serge Klochkov](https://github.com/slvrtrn)).
+* Add `SYSTEM UNLOAD PRIMARY KEY` to free up memory usage for a table's primary key. [#62738](https://github.com/ClickHouse/ClickHouse/pull/62738) ([Pablo Marcos](https://github.com/pamarcos)).
+* Added `value1`, `value2`, ..., `value10` columns to `system.text_log`. These columns contain values that were used to format the message. [#59619](https://github.com/ClickHouse/ClickHouse/pull/59619) ([Alexey Katsman](https://github.com/alexkats)).
+* Added persistent virtual column `_block_offset` which stores original number of row in block that was assigned at insert. Persistence of column `_block_offset` can be enabled by the MergeTree setting `enable_block_offset_column`. Added virtual column`_part_data_version` which contains either min block number or mutation version of part. Persistent virtual column `_block_number` is not considered experimental anymore. [#60676](https://github.com/ClickHouse/ClickHouse/pull/60676) ([Anton Popov](https://github.com/CurtizJ)).
+* Add a setting `input_format_json_throw_on_bad_escape_sequence`, disabling it allows saving bad escape sequences in JSON input formats. [#61889](https://github.com/ClickHouse/ClickHouse/pull/61889) ([Kruglov Pavel](https://github.com/Avogar)).
+
+#### Performance Improvement
+* JOIN filter push down improvements using equivalent sets. [#61216](https://github.com/ClickHouse/ClickHouse/pull/61216) ([Maksim Kita](https://github.com/kitaisreal)).
+* Convert OUTER JOIN to INNER JOIN optimization if the filter after JOIN always filters default values. Optimization can be controlled with setting `query_plan_convert_outer_join_to_inner_join`, enabled by default. [#62907](https://github.com/ClickHouse/ClickHouse/pull/62907) ([Maksim Kita](https://github.com/kitaisreal)).
+* Improvement for AWS S3. Client has to send header 'Keep-Alive: timeout=X' to the server. If a client receives a response from the server with that header, client has to use the value from the server. Also for a client it is better not to use a connection which is nearly expired in order to avoid connection close race. [#62249](https://github.com/ClickHouse/ClickHouse/pull/62249) ([Sema Checherinda](https://github.com/CheSema)).
+* Reduce overhead of the mutations for SELECTs (v2). [#60856](https://github.com/ClickHouse/ClickHouse/pull/60856) ([Azat Khuzhin](https://github.com/azat)).
+* More frequently invoked functions in PODArray are now force-inlined. [#61144](https://github.com/ClickHouse/ClickHouse/pull/61144) ([李扬](https://github.com/taiyang-li)).
+* Speed up parsing of JSON by skipping the rest of the object when all required columns are read. [#62210](https://github.com/ClickHouse/ClickHouse/pull/62210) ([lgbo](https://github.com/lgbo-ustc)).
+* Improve trivial insert select from files in file/s3/hdfs/url/... table functions. Add separate max_parsing_threads setting to control the number of threads used in parallel parsing. [#62404](https://github.com/ClickHouse/ClickHouse/pull/62404) ([Kruglov Pavel](https://github.com/Avogar)).
+* Functions `to_utc_timestamp` and `from_utc_timestamp` are now about 2x faster. [#62583](https://github.com/ClickHouse/ClickHouse/pull/62583) ([KevinyhZou](https://github.com/KevinyhZou)).
+* Functions `parseDateTimeOrNull`, `parseDateTimeOrZero`, `parseDateTimeInJodaSyntaxOrNull` and `parseDateTimeInJodaSyntaxOrZero` now run significantly faster (10x - 1000x) when the input contains mostly non-parseable values. [#62634](https://github.com/ClickHouse/ClickHouse/pull/62634) ([LiuNeng](https://github.com/liuneng1994)).
+* SELECTs against `system.query_cache` are now noticeably faster when the query cache contains lots of entries (e.g. more than 100.000). [#62671](https://github.com/ClickHouse/ClickHouse/pull/62671) ([Robert Schulze](https://github.com/rschu1ze)).
+* Less contention in filesystem cache (part 3): execute removal from filesystem without lock on space reservation attempt. [#61163](https://github.com/ClickHouse/ClickHouse/pull/61163) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Speed up dynamic resize of filesystem cache. [#61723](https://github.com/ClickHouse/ClickHouse/pull/61723) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Dictionary source with `INVALIDATE_QUERY` is not reloaded twice on startup. [#62050](https://github.com/ClickHouse/ClickHouse/pull/62050) ([vdimir](https://github.com/vdimir)).
+* Fix an issue where when a redundant `= 1` or `= 0` is added after a boolean expression involving the primary key, the primary index is not used. For example, both `SELECT * FROM <table> WHERE <primary-key> IN (<value>) = 1` and `SELECT * FROM <table> WHERE <primary-key> NOT IN (<value>) = 0` will both perform a full table scan, when the primary index can be used. [#62142](https://github.com/ClickHouse/ClickHouse/pull/62142) ([josh-hildred](https://github.com/josh-hildred)).
+* Return stream of chunks from `system.remote_data_paths` instead of accumulating the whole result in one big chunk. This allows to consume less memory, show intermediate progress and cancel the query. [#62613](https://github.com/ClickHouse/ClickHouse/pull/62613) ([Alexander Gololobov](https://github.com/davenger)).
+
+#### Experimental Feature
+* Support parallel write buffer for Azure Blob Storage managed by setting `azure_allow_parallel_part_upload`. [#62534](https://github.com/ClickHouse/ClickHouse/pull/62534) ([SmitaRKulkarni](https://github.com/SmitaRKulkarni)).
+* Userspace page cache works with static web storage (`disk(type = web)`) now. Use client setting `use_page_cache_for_disks_without_file_cache=1` to enable. [#61911](https://github.com/ClickHouse/ClickHouse/pull/61911) ([Michael Kolupaev](https://github.com/al13n321)).
+* Don't treat Bool and number variants as suspicious in the `Variant` type. [#61999](https://github.com/ClickHouse/ClickHouse/pull/61999) ([Kruglov Pavel](https://github.com/Avogar)).
+* Implement better conversion from String to `Variant` using parsing. [#62005](https://github.com/ClickHouse/ClickHouse/pull/62005) ([Kruglov Pavel](https://github.com/Avogar)).
+* Support `Variant` in JSONExtract functions. [#62014](https://github.com/ClickHouse/ClickHouse/pull/62014) ([Kruglov Pavel](https://github.com/Avogar)).
+* Mark type `Variant` as comparable so it can be used in primary key. [#62693](https://github.com/ClickHouse/ClickHouse/pull/62693) ([Kruglov Pavel](https://github.com/Avogar)).
+
+#### Improvement
+* For convenience purpose, `SELECT * FROM numbers() `will work in the same way as `SELECT * FROM system.numbers` - without a limit. [#61969](https://github.com/ClickHouse/ClickHouse/pull/61969) ([YenchangChan](https://github.com/YenchangChan)).
+* Introduce separate consumer/producer tags for the Kafka configuration. This avoids warnings from librdkafka (a bad C library with a lot of bugs) that consumer properties were specified for producer instances and vice versa (e.g. `Configuration property session.timeout.ms is a consumer property and will be ignored by this producer instance`). Closes: [#58983](https://github.com/ClickHouse/ClickHouse/issues/58983). [#58956](https://github.com/ClickHouse/ClickHouse/pull/58956) ([Aleksandr Musorin](https://github.com/AVMusorin)).
+* Functions `date_diff` and `age` now calculate their result at nanosecond instead of microsecond precision. They now also offer `nanosecond` (or `nanoseconds` or `ns`) as a possible value for the `unit` parameter. [#61409](https://github.com/ClickHouse/ClickHouse/pull/61409) ([Austin Kothig](https://github.com/kothiga)).
+* Added nano-, micro-, milliseconds unit for `date_trunc`. [#62335](https://github.com/ClickHouse/ClickHouse/pull/62335) ([Misz606](https://github.com/Misz606)).
+* Reload certificate chain during certificate reload. [#61671](https://github.com/ClickHouse/ClickHouse/pull/61671) ([Pervakov Grigorii](https://github.com/GrigoryPervakov)).
+* Try to prevent an error [#60432](https://github.com/ClickHouse/ClickHouse/issues/60432) by not allowing a table to be attached if there is an active replica for that replica path. [#61876](https://github.com/ClickHouse/ClickHouse/pull/61876) ([Arthur Passos](https://github.com/arthurpassos)).
+* Implement support for `input` for `clickhouse-local`. [#61923](https://github.com/ClickHouse/ClickHouse/pull/61923) ([Azat Khuzhin](https://github.com/azat)).
+* `Join` table engine with strictness `ANY` is consistent after reload. When several rows with the same key are inserted, the first one will have higher priority (before, it was chosen randomly upon table loading). close [#51027](https://github.com/ClickHouse/ClickHouse/issues/51027). [#61972](https://github.com/ClickHouse/ClickHouse/pull/61972) ([vdimir](https://github.com/vdimir)).
+* Automatically infer Nullable column types from Apache Arrow schema. [#61984](https://github.com/ClickHouse/ClickHouse/pull/61984) ([Maksim Kita](https://github.com/kitaisreal)).
+* Allow to cancel parallel merge of aggregate states during aggregation. Example: `uniqExact`. [#61992](https://github.com/ClickHouse/ClickHouse/pull/61992) ([Maksim Kita](https://github.com/kitaisreal)).
+* Use `system.keywords` to fill in the suggestions and also use them in the all places internally. [#62000](https://github.com/ClickHouse/ClickHouse/pull/62000) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* `OPTIMIZE FINAL` for `ReplicatedMergeTree` now will wait for currently active merges to finish and then reattempt to schedule a final merge. This will put it more in line with ordinary `MergeTree` behaviour. [#62067](https://github.com/ClickHouse/ClickHouse/pull/62067) ([Nikita Taranov](https://github.com/nickitat)).
+* While read data from a hive text file, it would use the first line of hive text file to resize of number of input fields, and sometimes the fields number of first line is not matched with the hive table defined , such as the hive table is defined to have 3 columns, like `test_tbl(a Int32, b Int32, c Int32)`, but the first line of text file only has 2 fields, and in this suitation, the input fields will be resized to 2, and if the next line of the text file has 3 fields, then the third field can not be read but set a default value 0, which is not right. [#62086](https://github.com/ClickHouse/ClickHouse/pull/62086) ([KevinyhZou](https://github.com/KevinyhZou)).
+* `CREATE AS` copies the table's comment. [#62117](https://github.com/ClickHouse/ClickHouse/pull/62117) ([Pablo Marcos](https://github.com/pamarcos)).
+* Add query progress to table zookeeper. [#62152](https://github.com/ClickHouse/ClickHouse/pull/62152) ([JackyWoo](https://github.com/JackyWoo)).
+* Add ability to turn on trace collector (Real and CPU) server-wide. [#62189](https://github.com/ClickHouse/ClickHouse/pull/62189) ([alesapin](https://github.com/alesapin)).
+* Added setting `lightweight_deletes_sync` (default value: 2 - wait all replicas synchronously). It is similar to setting `mutations_sync` but affects only behaviour of lightweight deletes. [#62195](https://github.com/ClickHouse/ClickHouse/pull/62195) ([Anton Popov](https://github.com/CurtizJ)).
+* Distinguish booleans and integers while parsing values for custom settings: `SET custom_a = true; SET custom_b = 1;`. [#62206](https://github.com/ClickHouse/ClickHouse/pull/62206) ([Vitaly Baranov](https://github.com/vitlibar)).
+* Support S3 access through AWS Private Link Interface endpoints. Closes [#60021](https://github.com/ClickHouse/ClickHouse/issues/60021), [#31074](https://github.com/ClickHouse/ClickHouse/issues/31074) and [#53761](https://github.com/ClickHouse/ClickHouse/issues/53761). [#62208](https://github.com/ClickHouse/ClickHouse/pull/62208) ([Arthur Passos](https://github.com/arthurpassos)).
+* Do not create a directory for UDF in clickhouse-client if it does not exist. This closes [#59597](https://github.com/ClickHouse/ClickHouse/issues/59597). [#62366](https://github.com/ClickHouse/ClickHouse/pull/62366) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* The query cache now no longer caches results of queries against system tables (`system.*`, `information_schema.*`, `INFORMATION_SCHEMA.*`). [#62376](https://github.com/ClickHouse/ClickHouse/pull/62376) ([Robert Schulze](https://github.com/rschu1ze)).
+* `MOVE PARTITION TO TABLE` query can be delayed or can throw `TOO_MANY_PARTS` exception to avoid exceeding limits on the part count. The same settings and limits are applied as for the`INSERT` query (see `max_parts_in_total`, `parts_to_delay_insert`, `parts_to_throw_insert`, `inactive_parts_to_throw_insert`, `inactive_parts_to_delay_insert`, `max_avg_part_size_for_too_many_parts`, `min_delay_to_insert_ms` and `max_delay_to_insert` settings). [#62420](https://github.com/ClickHouse/ClickHouse/pull/62420) ([Sergei Trifonov](https://github.com/serxa)).
+* Changed the default installation directory on macOS from `/usr/bin` to `/usr/local/bin`. This is necessary because Apple's System Integrity Protection introduced with macOS El Capitan (2015) prevents writing into `/usr/bin`, even with `sudo`. [#62489](https://github.com/ClickHouse/ClickHouse/pull/62489) ([haohang](https://github.com/yokofly)).
+* Make transform always return the first match. [#62518](https://github.com/ClickHouse/ClickHouse/pull/62518) ([Raúl Marín](https://github.com/Algunenano)).
+* Added the missing `hostname` column to system table `blob_storage_log`. [#62456](https://github.com/ClickHouse/ClickHouse/pull/62456) ([Jayme Bird](https://github.com/jaymebrd)).
+* For consistency with other system tables, `system.backup_log` now has a column `event_time`. [#62541](https://github.com/ClickHouse/ClickHouse/pull/62541) ([Jayme Bird](https://github.com/jaymebrd)).
+* Table `system.backup_log` now has the "default" sorting key which is `event_date, event_time`, the same as for other `_log` table engines. [#62667](https://github.com/ClickHouse/ClickHouse/pull/62667) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Avoid evaluating table DEFAULT expressions while executing `RESTORE`. [#62601](https://github.com/ClickHouse/ClickHouse/pull/62601) ([Vitaly Baranov](https://github.com/vitlibar)).
+* S3 storage and backups also need the same default keep alive settings as s3 disk. [#62648](https://github.com/ClickHouse/ClickHouse/pull/62648) ([Sema Checherinda](https://github.com/CheSema)).
+* Add librdkafka's (that infamous C library, which has a lot of bugs) client identifier to log messages to be able to differentiate log messages from different consumers of a single table. [#62813](https://github.com/ClickHouse/ClickHouse/pull/62813) ([János Benjamin Antal](https://github.com/antaljanosbenjamin)).
+* Allow special macros `{uuid}` and `{database}` in a Replicated database ZooKeeper path. [#62818](https://github.com/ClickHouse/ClickHouse/pull/62818) ([Vitaly Baranov](https://github.com/vitlibar)).
+* Allow quota key with different auth scheme in HTTP requests. [#62842](https://github.com/ClickHouse/ClickHouse/pull/62842) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Reduce the verbosity of command line argument `--help` in `clickhouse client` and `clickhouse local`. The previous output is now generated by `--help --verbose`. [#62973](https://github.com/ClickHouse/ClickHouse/pull/62973) ([Yarik Briukhovetskyi](https://github.com/yariks5s)).
+* `log_bin_use_v1_row_events` was removed in MySQL 8.3, and we adjust the experimental `MaterializedMySQL` engine for it [#60479](https://github.com/ClickHouse/ClickHouse/issues/60479). [#63101](https://github.com/ClickHouse/ClickHouse/pull/63101) ([Eugene Klimov](https://github.com/Slach)). Author: Nikolay Yankin.
+
+#### Build/Testing/Packaging Improvement
+* Vendor in Rust dependencies, so the Rust code (that we use for minor features for hype and lulz) can be built in a sane way, similarly to C++. [#62297](https://github.com/ClickHouse/ClickHouse/pull/62297) ([Raúl Marín](https://github.com/Algunenano)).
+* ClickHouse now uses OpenSSL 3.2 instead of BoringSSL. [#59870](https://github.com/ClickHouse/ClickHouse/pull/59870) ([Robert Schulze](https://github.com/rschu1ze)). Note that OpenSSL has generally worse engineering culture (such as non-zero number of sanitizer reports, that we had to patch, a complex build system with generated files, etc.) but has better compatibility.
+* Ignore DROP queries in stress test with 1/2 probability, use TRUNCATE instead of ignoring DROP in upgrade check for Memory/JOIN tables. [#61476](https://github.com/ClickHouse/ClickHouse/pull/61476) ([Kruglov Pavel](https://github.com/Avogar)).
+* Remove from the Keeper Docker image the volumes at /etc/clickhouse-keeper and /var/log/clickhouse-keeper. [#61683](https://github.com/ClickHouse/ClickHouse/pull/61683) ([Tristan](https://github.com/Tristan971)).
+* Add tests for all issues which are no longer relevant with Analyzer being enabled by default.

+
+#### Bug Fix (user-visible misbehavior in an official stable release)
+* Fix logical-error when undoing quorum insert transaction. [#61953](https://github.com/ClickHouse/ClickHouse/pull/61953) ([Han Fei](https://github.com/hanfei1991)).
+* Fix parser error when using COUNT(*) with FILTER clause [#61357](https://github.com/ClickHouse/ClickHouse/pull/61357) ([Duc Canh Le](https://github.com/canhld94)).
+* Fix logical error in `group_by_use_nulls` + grouping sets + analyzer + materialize/constant [#61567](https://github.com/ClickHouse/ClickHouse/pull/61567) ([Kruglov Pavel](https://github.com/Avogar)).

-* If a query with a syntax error contained `COLUMNS` matcher with a regular expression, the regular expression was compiled each time during the parser's backtracking, instead of being compiled once. This was a fundamental error. The compiled regexp was put to AST. But the letter A in AST means "abstract" which means it should not contain heavyweight objects. Parts of AST can be created and discarded during parsing, including a large number of backtracking. This leads to slowness on the parsing side and consequently allows DoS by a readonly user.

 * 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)).
+* Fix for the materialized view security issue, which allowed a user to insert into a table without required grants for that. Fix validates that the user has permission to insert not only into a materialized view but also into all underlying tables. This means that some queries, which worked before, now can fail with `Not enough privileges`. To address this problem, the release introduces a new feature of SQL security for views https://clickhouse.com/docs/en/sql-reference/statements/create/view#sql_security. [#54901](https://github.com/ClickHouse/ClickHouse/pull/54901) [#60439](https://github.com/ClickHouse/ClickHouse/pull/60439) ([pufit](https://github.com/pufit)).
 
 #### 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)).

 * Improve the operation of `sumMapFiltered` with NaN values. NaN values are now placed at the end (instead of randomly) and considered different from any values. `-0` is now also treated as equal to `0`; since 0 values are discarded, `-0` values are discarded too. [#58959](https://github.com/ClickHouse/ClickHouse/pull/58959) ([Raúl Marín](https://github.com/Algunenano)).
 * The function `visibleWidth` will behave according to the docs. In previous versions, it simply counted code points after string serialization, like the `lengthUTF8` function, but didn't consider zero-width and combining characters, full-width characters, tabs, and deletes. Now the behavior is changed accordingly. If you want to keep the old behavior, set `function_visible_width_behavior` to `0`, or set `compatibility` to `23.12` or lower. [#59022](https://github.com/ClickHouse/ClickHouse/pull/59022) ([Alexey Milovidov](https://github.com/alexey-milovidov)).

[#59305](https://github.com/ClickHouse/ClickHouse/pull/59305) ([Alexey Milovidov](https://github.com/alexey-milovidov)). Any attempt to use `Kusto` will result in exception.

 #### New Feature
 * Implement Variant data type that represents a union of other data types. Type `Variant(T1, T2, ..., TN)` means that each row of this type has a value of either type `T1` or `T2` or ... or `TN` or none of them (`NULL` value). Variant type is available under a setting `allow_experimental_variant_type`. Reference: [#54864](https://github.com/ClickHouse/ClickHouse/issues/54864).

 ### When Should I Report a Vulnerability?
 
@@ -58,3 +65,21 @@ As the security issue moves from triage, to identified fix, to release planning
 
 A public disclosure date is negotiated by the ClickHouse maintainers and the bug submitter. We prefer to fully disclose the bug as soon as possible once a user mitigation is available. It is reasonable to delay disclosure when the bug or the fix is not yet fully understood, the solution is not well-tested, or for vendor coordination. The timeframe for disclosure is from immediate (especially if it's already publicly known) to 90 days. For a vulnerability with a straightforward mitigation, we expect the report date to disclosure date to be on the order of 7 days.
 
+## Embargo Policy
+
+Open source users and support customers may subscribe to receive alerts during the embargo period by visiting [https://trust.clickhouse.com/?product=clickhouseoss](https://trust.clickhouse.com/?product=clickhouseoss), requesting access and subscribing for alerts. Subscribers agree not to make these notifications public, issue communications, share this information with others, or issue public patches before the disclosure date. Accidental disclosures must be reported immediately to trust@clickhouse.com. Failure to follow this policy or repeated leaks may result in removal from the subscriber list.
+
+Participation criteria:
+1. Be a current open source user or support customer with a valid corporate email domain (no @gmail.com, @azure.com, etc.).
+1. Sign up to the ClickHouse OSS Trust Center at [https://trust.clickhouse.com](https://trust.clickhouse.com).
+1. Accept the ClickHouse Security Vulnerability Response Policy as outlined above.
+1. Subscribe to ClickHouse OSS Trust Center alerts.
+
+Removal criteria:
+1. Members may be removed for failure to follow this policy or repeated leaks.
+1. Members may be removed for bounced messages (mail delivery failure).
+1. Members may unsubscribe at any time.
+
+Notification process:
+ClickHouse will post notifications within our OSS Trust Center and notify subscribers. Subscribers must log in to the Trust Center to download the notification. The notification will include the timeframe for public disclosure.
