+### ClickHouse release v23.3.6.7-lts (7e3f0a271b7) FIXME as compared to v23.3.5.9-lts (f5fbc2fd2b3)
+
+#### Improvement
+* Backported in [#51240](https://github.com/ClickHouse/ClickHouse/issues/51240): Improve the progress bar for file/s3/hdfs/url table functions by using chunk size from source data and using incremental total size counting in each thread. Fix the progress bar for *Cluster functions. This closes [#47250](https://github.com/ClickHouse/ClickHouse/issues/47250). [#51088](https://github.com/ClickHouse/ClickHouse/pull/51088) ([Kruglov Pavel](https://github.com/Avogar)).
+
+#### Build/Testing/Packaging Improvement
+* Backported in [#51529](https://github.com/ClickHouse/ClickHouse/issues/51529): Split huge `RUN` in Dockerfile into smaller conditional.

Downgrade the base repo to ubuntu:20.04 to address the issues on older docker versions. Upgrade golang version to address golang vulnerabilities. [#51504](https://github.com/ClickHouse/ClickHouse/pull/51504) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+
+#### Bug Fix (user-visible misbehavior in an official stable release)
+
+* Fix type of LDAP server params hash in cache entry [#50865](https://github.com/ClickHouse/ClickHouse/pull/50865) ([Julian Maicher](https://github.com/jmaicher)).

+### ClickHouse release v23.6.1.1524-stable (d1c7e13d088) FIXME as compared to v23.5.1.3174-stable (2fec796e73e)
+
+#### Backward Incompatible Change
+* Delete feature `do_not_evict_index_and_mark_files` in the fs cache. This feature was only making things worse. [#51253](https://github.com/ClickHouse/ClickHouse/pull/51253) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Remove ALTER support for experimental LIVE VIEW. [#51287](https://github.com/ClickHouse/ClickHouse/pull/51287) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+
+#### New Feature
+* Add setting `session_timezone`, it is used as default timezone for session when not explicitly specified. [#44149](https://github.com/ClickHouse/ClickHouse/pull/44149) ([Andrey Zvonov](https://github.com/zvonand)).
+* Added overlay database engine and representation of a directory as a database This commit adds 4 databases: 1. DatabaseOverlay: Implements the IDatabase interface. Allow to combine multiple databases, such as FileSystem and Memory. Internally, it stores a vector with other database pointers and proxies requests to them in turn until it is executed successfully. 2. DatabaseFilesystem: allows to read-only interact with files stored on the file system. Internally, it uses TableFunctionFile to implicitly load file when a user requests the table. Result of TableFunctionFile call cached inside to provide quick access. 3. DatabaseS3: allows to read-only interact with s3 storage. It uses TableFunctionS3 to implicitly load table from s3 4. DatabaseHDFS: allows to interact with hdfs storage. It uses TableFunctionHDFS to implicitly load table from hdfs. [#48821](https://github.com/ClickHouse/ClickHouse/pull/48821) ([alekseygolub](https://github.com/alekseygolub)).
+* Add a new setting named `use_mysql_types_in_show_columns` to alter the `SHOW COLUMNS` SQL statement to display MySQL equivalent types when a client is connected via the MySQL compatibility port. [#49577](https://github.com/ClickHouse/ClickHouse/pull/49577) ([Thomas Panetti](https://github.com/tpanetti)).
+* Added option `--rename_files_after_processing `. This closes [#34207](https://github.com/ClickHouse/ClickHouse/issues/34207). [#49626](https://github.com/ClickHouse/ClickHouse/pull/49626) ([alekseygolub](https://github.com/alekseygolub)).
+* 1. Add `TableFunctionRedis` 3. Add table engine Redis 4. Add `RedisCommon` which contains Redis related tools and types 5. Support `equals` and `in` filter push down into Redis. [#50150](https://github.com/ClickHouse/ClickHouse/pull/50150) ([JackyWoo](https://github.com/JackyWoo)).
+* Allow to skip empty files in file/s3/url/hdfs table functions using settings `s3_skip_empty_files`, `hdfs_skip_empty_files`, `engine_file_skip_empty_files`, `engine_url_skip_empty_files`. [#50364](https://github.com/ClickHouse/ClickHouse/pull/50364) ([Kruglov Pavel](https://github.com/Avogar)).
+* Clickhouse-client can now be called with a connection instead of "--host", "--port", "--user" etc. [#50689](https://github.com/ClickHouse/ClickHouse/pull/50689) ([Alexey Gerasimchuck](https://github.com/Demilivor)).
+* Codec DEFLATE_QPL is now controlled via server setting "enable_deflate_qpl_codec" (default: false) instead of setting "allow_experimental_codecs". This marks QPL_DEFLATE non-experimental. [#50775](https://github.com/ClickHouse/ClickHouse/pull/50775) ([Robert Schulze](https://github.com/rschu1ze)).
+
+#### Performance Improvement
+* Improve performance with enabled QueryProfiler using thread-local timer_id instead of global object. [#48778](https://github.com/ClickHouse/ClickHouse/pull/48778) ([Jiebin Sun](https://github.com/jiebinn)).
+* Rewrite CapnProto input/output format to improve its performance. Map column names and CapnProto fields case insensitive, fix reading/writing of nested structure fields. [#49752](https://github.com/ClickHouse/ClickHouse/pull/49752) ([Kruglov Pavel](https://github.com/Avogar)).
+* Optimize parquet write performance for parallel threads. [#50102](https://github.com/ClickHouse/ClickHouse/pull/50102) ([Hongbin Ma](https://github.com/binmahone)).
+* ### Documentation entry for user-facing changes Disable `parallelize_output_from_storages` for processing MATERIALIZED VIEWs and storages with one block only. [#50214](https://github.com/ClickHouse/ClickHouse/pull/50214) ([Azat Khuzhin](https://github.com/azat)).
+* Merge PR https://github.com/ClickHouse/ClickHouse/pull/46558 (Avoid processing already sorted data). Avoid block permutation during sort if the block is already sorted. [#50697](https://github.com/ClickHouse/ClickHouse/pull/50697) ([Maksim Kita](https://github.com/kitaisreal)).
+* In the earlier PRs ([#50062](https://github.com/ClickHouse/ClickHouse/issues/50062), [#50307](https://github.com/ClickHouse/ClickHouse/issues/50307)), we used to propose an optimization pattern which transforms the predicates with toYear/toYYYYMM into its equivalent but converter-free form. This transformation could bring significant performance impact to some workloads, such as SSB. However, as issue [#50628](https://github.com/ClickHouse/ClickHouse/issues/50628) indicated, these two PRs would introduce some issues which may results in incomplete query results, and as a result, they were reverted by [#50629](https://github.com/ClickHouse/ClickHouse/issues/50629). [#50951](https://github.com/ClickHouse/ClickHouse/pull/50951) ([Zhiguo Zhou](https://github.com/ZhiguoZh)).
+* Make multiple list requests to ZooKeeper in parallel to speed up reading from system.zookeeper table. [#51042](https://github.com/ClickHouse/ClickHouse/pull/51042) ([Alexander Gololobov](https://github.com/davenger)).
+* Speedup initialization of DateTime lookup tables for time zones. This should reduce startup/connect time of clickhouse client especially in debug build as it is rather heavy. [#51347](https://github.com/ClickHouse/ClickHouse/pull/51347) ([Alexander Gololobov](https://github.com/davenger)).
+
+#### Improvement
+* Allow to cast IPv6 to IPv4 address for CIDR ::ffff:0:0/96 (IPv4-mapped addresses). [#49759](https://github.com/ClickHouse/ClickHouse/pull/49759) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
+* Update MongoDB protocol to support MongoDB 5.1 version and newer. Support for the versions with the old protocol (<3.6) is preserved. Closes [#45621](https://github.com/ClickHouse/ClickHouse/issues/45621), [#49879](https://github.com/ClickHouse/ClickHouse/issues/49879). [#50061](https://github.com/ClickHouse/ClickHouse/pull/50061) ([Nikolay Degterinsky](https://github.com/evillique)).
+* Improved scheduling of merge selecting and cleanup tasks in `ReplicatedMergeTree`. The tasks will not be executed too frequently when there's nothing to merge or cleanup. Added settings `max_merge_selecting_sleep_ms`, `merge_selecting_sleep_slowdown_factor`, `max_cleanup_delay_period` and `cleanup_thread_preferred_points_per_iteration`. It should close [#31919](https://github.com/ClickHouse/ClickHouse/issues/31919). [#50107](https://github.com/ClickHouse/ClickHouse/pull/50107) ([Alexander Tokmakov](https://github.com/tavplubix)).
+* Support parallel replicas with the analyzer. [#50441](https://github.com/ClickHouse/ClickHouse/pull/50441) ([Raúl Marín](https://github.com/Algunenano)).
+* Add setting `input_format_max_bytes_to_read_for_schema_inference` to limit the number of bytes to read in schema inference. Closes [#50577](https://github.com/ClickHouse/ClickHouse/issues/50577). [#50592](https://github.com/ClickHouse/ClickHouse/pull/50592) ([Kruglov Pavel](https://github.com/Avogar)).
+* Respect setting input_format_as_default in schema inference. [#50602](https://github.com/ClickHouse/ClickHouse/pull/50602) ([Kruglov Pavel](https://github.com/Avogar)).
+* Make filter push down through cross join. [#50605](https://github.com/ClickHouse/ClickHouse/pull/50605) ([Han Fei](https://github.com/hanfei1991)).

+* Allow to skip trailing empty lines in CSV/TSV/CustomSeparated formats via settings `input_format_csv_skip_trailing_empty_lines`, `input_format_tsv_skip_trailing_empty_lines` and `input_format_custom_skip_trailing_empty_lines` (disabled by default). Closes [#49315](https://github.com/ClickHouse/ClickHouse/issues/49315). [#50635](https://github.com/ClickHouse/ClickHouse/pull/50635) ([Kruglov Pavel](https://github.com/Avogar)).
+* Functions "toDateOrDefault|OrNull()" and "accuateCast[OrDefault|OrNull]()" now correctly parse numeric arguments. [#50709](https://github.com/ClickHouse/ClickHouse/pull/50709) ([Dmitry Kardymon](https://github.com/kardymonds)).
+* Currently, the csv input format can not parse the csv file with whitespace or \t field delimiter, and these delimiters is supported in spark. [#50712](https://github.com/ClickHouse/ClickHouse/pull/50712) ([KevinyhZou](https://github.com/KevinyhZou)).
+* Settings `number_of_mutations_to_delay` and `number_of_mutations_to_throw` are enabled by default now with values 500 and 1000 respectively. [#50726](https://github.com/ClickHouse/ClickHouse/pull/50726) ([Anton Popov](https://github.com/CurtizJ)).
+* Keeper improvement: add feature flags for Keeper API. Each feature flag can be disabled or enabled by defining it under `keeper_server.feature_flags` config. E.g. to enable `CheckNotExists` request, `keeper_server.feature_flags.check_not_exists` should be set to `1` on Keeper. [#50796](https://github.com/ClickHouse/ClickHouse/pull/50796) ([Antonio Andelic](https://github.com/antonio2368)).
+* The dashboard correctly shows missing values. This closes [#50831](https://github.com/ClickHouse/ClickHouse/issues/50831). [#50832](https://github.com/ClickHouse/ClickHouse/pull/50832) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* CGroups metrics related to CPU are replaced with one metric, `CGroupMaxCPU` for better usability. The `Normalized` CPU usage metrics will be normalized to CGroups limits instead of the total number of CPUs when they are set. This closes [#50836](https://github.com/ClickHouse/ClickHouse/issues/50836). [#50835](https://github.com/ClickHouse/ClickHouse/pull/50835) ([Alexey Milovidov](https://github.com/alexey-milovidov)).

+* Suggest using `APPEND` or `TRUNCATE` for `INTO OUTFILE` when file exists. [#50950](https://github.com/ClickHouse/ClickHouse/pull/50950) ([alekar](https://github.com/alekar)).
+* Add embedded keeper-client to standalone keeper binary. [#50964](https://github.com/ClickHouse/ClickHouse/pull/50964) ([pufit](https://github.com/pufit)).
+* Command line parameter "--password" in clickhouse-client can now be specified only once. [#50966](https://github.com/ClickHouse/ClickHouse/pull/50966) ([Alexey Gerasimchuck](https://github.com/Demilivor)).

+* Do not replicate `ALTER PARTITION` queries and mutations through `Replicated` database if it has only one shard and the underlying table is `ReplicatedMergeTree`. [#51049](https://github.com/ClickHouse/ClickHouse/pull/51049) ([Alexander Tokmakov](https://github.com/tavplubix)).
+* Improve the progress bar for file/s3/hdfs/url table functions by using chunk size from source data and using incremental total size counting in each thread. Fix the progress bar for *Cluster functions. This closes [#47250](https://github.com/ClickHouse/ClickHouse/issues/47250). [#51088](https://github.com/ClickHouse/ClickHouse/pull/51088) ([Kruglov Pavel](https://github.com/Avogar)).

+* We have found a bug in LLVM that makes the usage of `compile_expressions` setting unsafe. It is disabled by default. [#51368](https://github.com/ClickHouse/ClickHouse/pull/51368) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Issue [#50220](https://github.com/ClickHouse/ClickHouse/issues/50220) reports a core in `grace_hash` join. We finally reproduce the exception on local, and found that the issue is related to the failure of creating temporary file. Somehow this is triggered in https://github.com/ClickHouse/ClickHouse/pull/49816 https://github.com/ClickHouse/ClickHouse/pull/49483. [#51382](https://github.com/ClickHouse/ClickHouse/pull/51382) ([lgbo](https://github.com/lgbo-ustc)).

+* In https://github.com/ClickHouse/ClickHouse/pull/51143 the fasstests failed, but the status wasn't created because of the chown `file not found`. This addresses it. Decrease the default values for `http-max-field-value-size` and `http_max_field_name_size` to 128K. [#51163](https://github.com/ClickHouse/ClickHouse/pull/51163) ([Mikhail f.

+* Split huge `RUN` in Dockerfile into smaller conditional. Install the necessary tools on demand in the same `RUN` layer, and remove them after that. Upgrade the OS only once at the beginning. Use a modern way to check the signed repository. Downgrade the base repo to ubuntu:20.04 to address the issues on older docker versions. Upgrade golang version to address golang vulnerabilities. [#51504](https://github.com/ClickHouse/ClickHouse/pull/51504) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+* This a follow-up for [#51504](https://github.com/ClickHouse/ClickHouse/issues/51504), the cleanup was lost during refactoring. [#51564](https://github.com/ClickHouse/ClickHouse/pull/51564) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).

Redis engine also supports scanning queries, such as `where k > xx`, but it has some limitations:
-1. Scanning query may produce some duplicated keys in a very rare case when it is rehashing. See details in [Redis Scan](https://github.com/redis/redis/blob/e4d183afd33e0b2e6e8d1c79a832f678a04a7886/src/dict.c#L1186-L1269)

2. During the scanning, keys could be created and deleted, so the resulting dataset can not represent a valid point in time.
