+* Fix NPE when using IN clause with a subquery with a tuple. [#6125](https://github.com/yandex/ClickHouse/issues/6125) [#6550](https://github.com/yandex/ClickHouse/pull/6550) ([tavplubix](https://github.com/tavplubix))
+* Fixed an issue that if a stale replica becomes alive, it may still have data parts that were removed by DROP PARTITION. [#6522](https://github.com/yandex/ClickHouse/issues/6522) [#6523](https://github.com/yandex/ClickHouse/pull/6523) ([tavplubix](https://github.com/tavplubix))
+* Fixed issue with parsing CSV [#6426](https://github.com/yandex/ClickHouse/issues/6426) [#6559](https://github.com/yandex/ClickHouse/pull/6559) ([tavplubix](https://github.com/tavplubix))
+* Fixed data race in system.parts table and ALTER query. This fixes [#6245](https://github.com/yandex/ClickHouse/issues/6245). [#6513](https://github.com/yandex/ClickHouse/pull/6513) ([alexey-milovidov](https://github.com/alexey-milovidov))
+* Fixed wrong code in mutations that may lead to memory corruption. Fixed segfault with read of address `0x14c0` that may happed due to concurrent `DROP TABLE` and `SELECT` from `system.parts` or `system.parts_columns`. Fixed race condition in preparation of mutation queries. Fixed deadlock caused by `OPTIMIZE` of Replicated tables and concurrent modification operations like ALTERs. [#6514](https://github.com/yandex/ClickHouse/pull/6514) ([alexey-milovidov](https://github.com/alexey-milovidov))
+
+## ClickHouse release 19.13.2.19, 2019-08-14
+
+### New Feature
+* Sampling profiler on query level. [Example](https://gist.github.com/alexey-milovidov/92758583dd41c24c360fdb8d6a4da194). [#4247](https://github.com/yandex/ClickHouse/issues/4247) ([laplab](https://github.com/laplab)) [#6124](https://github.com/yandex/ClickHouse/pull/6124) ([alexey-milovidov](https://github.com/alexey-milovidov)) [#6250](https://github.com/yandex/ClickHouse/pull/6250) [#6283](https://github.com/yandex/ClickHouse/pull/6283) [#6386](https://github.com/yandex/ClickHouse/pull/6386) 
+* Allow to specify a list of columns with `COLUMNS('regexp')` expression that works like a more sophisticated variant of `*` asterisk. [#5951](https://github.com/yandex/ClickHouse/pull/5951)  ([mfridental](https://github.com/mfridental)), ([alexey-milovidov](https://github.com/alexey-milovidov))
+* `CREATE TABLE AS table_function()` is now possible [#6057](https://github.com/yandex/ClickHouse/pull/6057) ([dimarub2000](https://github.com/dimarub2000))
+* Adam optimizer for stochastic gradient descent is used by default in `stochasticLinearRegression()` and `stochasticLogisticRegression()` aggregate functions, because it shows good quality without almost any tuning. [#6000](https://github.com/yandex/ClickHouse/pull/6000) ([Quid37](https://github.com/Quid37))
+* Added functions for working with the сustom week number [#5212](https://github.com/yandex/ClickHouse/pull/5212) ([Andy Yang](https://github.com/andyyzh))
+* `RENAME` queries now work with all storages. [#5953](https://github.com/yandex/ClickHouse/pull/5953) ([Ivan](https://github.com/abyss7))
+* Now client receive logs from server with any desired level by setting `send_logs_level` regardless to the log level specified in server settings. [#5964](https://github.com/yandex/ClickHouse/pull/5964) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov))
+
+### Backward Incompatible Change
+* The setting `input_format_defaults_for_omitted_fields` is enabled by default. Inserts in Distibuted tables need this setting to be the same on cluster (you need to set it before rolling update). It enables calculation of complex default expressions for omitted fields in `JSONEachRow` and `CSV*` formats. It should be the expected behaviour but may lead to negligible performance difference. [#6043](https://github.com/yandex/ClickHouse/pull/6043) ([Artem Zuikov](https://github.com/4ertus2)), [#5625](https://github.com/yandex/ClickHouse/pull/5625) ([akuzm](https://github.com/akuzm)) 
+
+### Experimental features
+* New query processing pipeline. Use `experimental_use_processors=1` option to enable it. Use for your own trouble. [#4914](https://github.com/yandex/ClickHouse/pull/4914) ([Nikolai Kochetov](https://github.com/KochetovNicolai))
+
+### Bug Fix
+* Kafka integration has been fixed in this version.
+* Fixed `DoubleDelta` encoding of `Int64` for large `DoubleDelta` values, improved `DoubleDelta` encoding for random data for `Int32`. [#5998](https://github.com/yandex/ClickHouse/pull/5998) ([Vasily Nemkov](https://github.com/Enmk))
+* Fixed overestimation of `max_rows_to_read` if the setting `merge_tree_uniform_read_distribution` is set to 0. [#6019](https://github.com/yandex/ClickHouse/pull/6019) ([alexey-milovidov](https://github.com/alexey-milovidov))
+
+### Improvement
+* Throws an exception if `config.d` file doesn't have the corresponding root element as the config file [#6123](https://github.com/yandex/ClickHouse/pull/6123) ([dimarub2000](https://github.com/dimarub2000))
+
+### Performance Improvement
+* Optimize `count()`. Now it uses the smallest column (if possible). [#6028](https://github.com/yandex/ClickHouse/pull/6028) ([Amos Bird](https://github.com/amosbird))
+
+### Build/Testing/Packaging Improvement
+* Report memory usage in performance tests. [#5899](https://github.com/yandex/ClickHouse/pull/5899) ([akuzm](https://github.com/akuzm))
+* Fix build with external `libcxx` [#6010](https://github.com/yandex/ClickHouse/pull/6010) ([Ivan](https://github.com/abyss7))
+* Fix shared build with `rdkafka` library [#6101](https://github.com/yandex/ClickHouse/pull/6101) ([Ivan](https://github.com/abyss7))

+
+### Backward Incompatible Change
+* `Kafka` is broken in this version.
+
+
+## ClickHouse release 19.11.3.11, 2019-07-18
+
+### New Feature
+* Added support for prepared statements. [#5331](https://github.com/yandex/ClickHouse/pull/5331/) ([Alexander](https://github.com/sanych73)) [#5630](https://github.com/yandex/ClickHouse/pull/5630) ([alexey-milovidov](https://github.com/alexey-milovidov))
+* `DoubleDelta` and `Gorilla` column codecs [#5600](https://github.com/yandex/ClickHouse/pull/5600) ([Vasily Nemkov](https://github.com/Enmk))
+* Added `os_thread_priority` setting that allows to control the "nice" value of query processing threads that is used by OS to adjust dynamic scheduling priority. It requires `CAP_SYS_NICE` capabilities to work. This implements [#5858](https://github.com/yandex/ClickHouse/issues/5858) [#5909](https://github.com/yandex/ClickHouse/pull/5909) ([alexey-milovidov](https://github.com/alexey-milovidov))
+* Implement `_topic`, `_offset`, `_key` columns for Kafka engine [#5382](https://github.com/yandex/ClickHouse/pull/5382) ([Ivan](https://github.com/abyss7)) Note that Kafka is broken in this version.
+* Add aggregate function combinator `-Resample` [#5590](https://github.com/yandex/ClickHouse/pull/5590) ([hcz](https://github.com/hczhcz))

+* Avoid hanging connections when server thread pool is full. It is important for connections from `remote` table function or connections to a shard without replicas when there is long connection timeout. This fixes [#5878](https://github.com/yandex/ClickHouse/issues/5878) [#5881](https://github.com/yandex/ClickHouse/pull/5881) ([alexey-milovidov](https://github.com/alexey-milovidov))
+* Support for constant arguments to `evalMLModel` function. This fixes [#5817](https://github.com/yandex/ClickHouse/issues/5817) [#5820](https://github.com/yandex/ClickHouse/pull/5820) ([alexey-milovidov](https://github.com/alexey-milovidov))

+* Fixed buffer underflow in `visitParamExtractRaw`. This fixes [#5901](https://github.com/yandex/ClickHouse/issues/5901) [#5902](https://github.com/yandex/ClickHouse/pull/5902) ([alexey-milovidov](https://github.com/alexey-milovidov))
+* Now distributed `DROP/ALTER/TRUNCATE/OPTIMIZE ON CLUSTER` queries will be executed directly on leader replica. [#5757](https://github.com/yandex/ClickHouse/pull/5757) ([alesapin](https://github.com/alesapin))
+* Fix `coalesce` for `ColumnConst` with `ColumnNullable` + related changes. [#5755](https://github.com/yandex/ClickHouse/pull/5755) ([Artem Zuikov](https://github.com/4ertus2))
+* Fix the `ReadBufferFromKafkaConsumer` so that it keeps reading new messages after `commit()` even if it was stalled before [#5852](https://github.com/yandex/ClickHouse/pull/5852) ([Ivan](https://github.com/abyss7))
+* Fix `FULL` and `RIGHT` JOIN results when joining on `Nullable` keys in right table. [#5859](https://github.com/yandex/ClickHouse/pull/5859) ([Artem Zuikov](https://github.com/4ertus2))
+* Possible fix of infinite sleeping of low-priority queries. [#5842](https://github.com/yandex/ClickHouse/pull/5842) ([alexey-milovidov](https://github.com/alexey-milovidov))
+* Fix race condition, which cause that some queries may not appear in query_log after `SYSTEM FLUSH LOGS` query. [#5456](https://github.com/yandex/ClickHouse/issues/5456) [#5685](https://github.com/yandex/ClickHouse/pull/5685) ([Anton Popov](https://github.com/CurtizJ))
+* Fixed `heap-use-after-free` ASan warning in ClusterCopier caused by watch which try to use already removed copier object. [#5871](https://github.com/yandex/ClickHouse/pull/5871) ([Nikolai Kochetov](https://github.com/KochetovNicolai))
+* Fixed wrong `StringRef` pointer returned by some implementations of `IColumn::deserializeAndInsertFromArena`. This bug affected only unit-tests. [#5973](https://github.com/yandex/ClickHouse/pull/5973) ([Nikolai Kochetov](https://github.com/KochetovNicolai))
+* Prevent source and intermediate array join columns of masking same name columns. [#5941](https://github.com/yandex/ClickHouse/pull/5941) ([Artem Zuikov](https://github.com/4ertus2))
+* Fix insert and select query to MySQL engine with MySQL style identifier quoting. [#5704](https://github.com/yandex/ClickHouse/pull/5704) ([Winter Zhang](https://github.com/zhang2014))
+* Now `CHECK TABLE` query can work with MergeTree engine family. It returns check status and message if any for each part (or file in case of simplier engines). Also, fix bug in fetch of a broken part. [#5865](https://github.com/yandex/ClickHouse/pull/5865) ([alesapin](https://github.com/alesapin))
+* Fix SPLIT_SHARED_LIBRARIES runtime [#5793](https://github.com/yandex/ClickHouse/pull/5793) ([Danila Kutenin](https://github.com/danlark1))

+
+### Improvement
+* Allow unresolvable addresses in cluster configuration. They will be considered unavailable and tried to resolve at every connection attempt. This is especially useful for Kubernetes. This fixes [#5714](https://github.com/yandex/ClickHouse/issues/5714) [#5924](https://github.com/yandex/ClickHouse/pull/5924) ([alexey-milovidov](https://github.com/alexey-milovidov))
+* Close idle TCP connections (with one hour timeout by default). This is especially important for large clusters with multiple distributed tables on every server, because every server can possibly keep a connection pool to every other server, and after peak query concurrency, connections will stall. This fixes [#5879](https://github.com/yandex/ClickHouse/issues/5879) [#5880](https://github.com/yandex/ClickHouse/pull/5880) ([alexey-milovidov](https://github.com/alexey-milovidov))

+* Show which table is missing column in error messages. [#5768](https://github.com/yandex/ClickHouse/pull/5768) ([Ivan](https://github.com/abyss7))
+* Disallow run query with same query_id by various users [#5430](https://github.com/yandex/ClickHouse/pull/5430) ([proller](https://github.com/proller))
+* More robust code for sending metrics to Graphite. It will work even during long multiple `RENAME TABLE` operation. [#5875](https://github.com/yandex/ClickHouse/pull/5875) ([alexey-milovidov](https://github.com/alexey-milovidov))
+* More informative error messages will be displayed when ThreadPool cannot schedule a task for execution. This fixes [#5305](https://github.com/yandex/ClickHouse/issues/5305) [#5801](https://github.com/yandex/ClickHouse/pull/5801) ([alexey-milovidov](https://github.com/alexey-milovidov))

+
+### Backward Incompatible Change
+* `Kafka` is broken in this version.
+* Enable `adaptive_index_granularity` = 10MB by default for new `MergeTree` tables. If you created new MergeTree tables on version 19.11+, downgrade to versions prior to 19.6 will be impossible. [#5628](https://github.com/yandex/ClickHouse/pull/5628) ([alesapin](https://github.com/alesapin))
+* Removed obsolete undocumented embedded dictionaries that were used by Yandex.Metrica. The functions `OSIn`, `SEIn`, `OSToRoot`, `SEToRoot`, `OSHierarchy`, `SEHierarchy` are no longer available. If you are using these functions, write email to clickhouse-feedback@yandex-team.com. Note: at the last moment we decided to keep these functions for a while. [#5780](https://github.com/yandex/ClickHouse/pull/5780) ([alexey-milovidov](https://github.com/alexey-milovidov))
+
+
+## ClickHouse release 19.10.1.5, 2019-07-12
+
+### New Feature
+* Add new column codec: `T64`. Made for (U)IntX/EnumX/Data(Time)/DecimalX columns. It should be good for columns with constant or small range values. Codec itself allows enlarge or shrink data type without re-compression. [#5557](https://github.com/yandex/ClickHouse/pull/5557) ([Artem Zuikov](https://github.com/4ertus2))
+* Add database engine `MySQL` that allow to view all the tables in remote MySQL server [#5599](https://github.com/yandex/ClickHouse/pull/5599) ([Winter Zhang](https://github.com/zhang2014))
+* `bitmapContains` implementation. It's 2x faster than `bitmapHasAny` if the second bitmap contains one element. [#5535](https://github.com/yandex/ClickHouse/pull/5535) ([Zhichang Yu](https://github.com/yuzhichang))
+* Support for `crc32` function (with behaviour exactly as in MySQL or PHP). Do not use it if you need a hash function. [#5661](https://github.com/yandex/ClickHouse/pull/5661) ([Remen Ivan](https://github.com/BHYCHIK))
+* Implemented `SYSTEM START/STOP DISTRIBUTED SENDS` queries to control asynchronous inserts into `Distributed` tables. [#4935](https://github.com/yandex/ClickHouse/pull/4935) ([Winter Zhang](https://github.com/zhang2014))
+
+### Bug Fix
+* Ignore query execution limits and max parts size for merge limits while executing mutations. [#5659](https://github.com/yandex/ClickHouse/pull/5659) ([Anton Popov](https://github.com/CurtizJ))
+* Fix bug which may lead to deduplication of normal blocks (extremely rare) and insertion of duplicate blocks (more often). [#5549](https://github.com/yandex/ClickHouse/pull/5549) ([alesapin](https://github.com/alesapin))
+* Fix of function `arrayEnumerateUniqRanked` for arguments with empty arrays [#5559](https://github.com/yandex/ClickHouse/pull/5559) ([proller](https://github.com/proller))
+* Don't subscribe to Kafka topics without intent to poll any messages. [#5698](https://github.com/yandex/ClickHouse/pull/5698) ([Ivan](https://github.com/abyss7))
+* Make setting `join_use_nulls` get no effect for types that cannot be inside Nullable [#5700](https://github.com/yandex/ClickHouse/pull/5700) ([Olga Khvostikova](https://github.com/stavrolia))
+* Fixed `Incorrect size of index granularity` errors [#5720](https://github.com/yandex/ClickHouse/pull/5720) ([coraxster](https://github.com/coraxster))
+* Fix Float to Decimal convert overflow [#5607](https://github.com/yandex/ClickHouse/pull/5607) ([coraxster](https://github.com/coraxster))
+* Flush buffer when `WriteBufferFromHDFS`'s destructor is called. This fixes writing into `HDFS`. [#5684](https://github.com/yandex/ClickHouse/pull/5684) ([Xindong Peng](https://github.com/eejoin))
+
+### Improvement
+* Treat empty cells in `CSV` as default values when the setting `input_format_defaults_for_omitted_fields` is enabled. [#5625](https://github.com/yandex/ClickHouse/pull/5625) ([akuzm](https://github.com/akuzm))
+* Non-blocking loading of external dictionaries. [#5567](https://github.com/yandex/ClickHouse/pull/5567) ([Vitaly Baranov](https://github.com/vitlibar))
+* Network timeouts can be dynamically changed for already established connections according to the settings. [#4558](https://github.com/yandex/ClickHouse/pull/4558) ([Konstantin Podshumok](https://github.com/podshumok))
+* Using "public_suffix_list" for functions `firstSignificantSubdomain`, `cutToFirstSignificantSubdomain`. It's using a perfect hash table generated by `gperf` with a list generated from the file: [https://publicsuffix.org/list/public_suffix_list.dat](https://publicsuffix.org/list/public_suffix_list.dat). (for example, now we recognize the domain `ac.uk` as non-significant). [#5030](https://github.com/yandex/ClickHouse/pull/5030) ([Guillaume Tassery](https://github.com/YiuRULE))
+* Adopted `IPv6` data type in system tables; unified client info columns in `system.processes` and `system.query_log` [#5640](https://github.com/yandex/ClickHouse/pull/5640) ([alexey-milovidov](https://github.com/alexey-milovidov))
+* Using sessions for connections with MySQL compatibility protocol. #5476 [#5646](https://github.com/yandex/ClickHouse/pull/5646) ([Yuriy Baranov](https://github.com/yurriy))
+* Support more `ALTER` queries `ON CLUSTER`. [#5593](https://github.com/yandex/ClickHouse/pull/5593) [#5613](https://github.com/yandex/ClickHouse/pull/5613) ([sundyli](https://github.com/sundy-li))
+* Support `<logger>` section in `clickhouse-local` config file. [#5540](https://github.com/yandex/ClickHouse/pull/5540) ([proller](https://github.com/proller))
+* Allow run query with `remote` table function in `clickhouse-local` [#5627](https://github.com/yandex/ClickHouse/pull/5627) ([proller](https://github.com/proller))
+
+### Performance Improvement
+* Add the possibility to write the final mark at the end of MergeTree columns. It allows to avoid useless reads for keys that are out of table data range. It is enabled only if adaptive index granularity is in use. [#5624](https://github.com/yandex/ClickHouse/pull/5624) ([alesapin](https://github.com/alesapin))
+* Improved performance of MergeTree tables on very slow filesystems by reducing number of `stat` syscalls. [#5648](https://github.com/yandex/ClickHouse/pull/5648) ([alexey-milovidov](https://github.com/alexey-milovidov))
+* Fixed performance degradation in reading from MergeTree tables that was introduced in version 19.6. Fixes #5631. [#5633](https://github.com/yandex/ClickHouse/pull/5633) ([alexey-milovidov](https://github.com/alexey-milovidov))
+
+### Build/Testing/Packaging Improvement
+* Implemented `TestKeeper` as an implementation of ZooKeeper interface used for testing [#5643](https://github.com/yandex/ClickHouse/pull/5643) ([alexey-milovidov](https://github.com/alexey-milovidov)) ([levushkin aleksej](https://github.com/alexey-milovidov))
+* From now on `.sql` tests can be run isolated by server, in parallel, with random database. It allows to run them faster, add new tests with custom server configurations, and be sure that different tests doesn't affect each other. [#5554](https://github.com/yandex/ClickHouse/pull/5554) ([Ivan](https://github.com/abyss7))
+* Remove `<name>` and `<metrics>` from performance tests [#5672](https://github.com/yandex/ClickHouse/pull/5672) ([Olga Khvostikova](https://github.com/stavrolia))
+* Fixed "select_format" performance test for `Pretty` formats [#5642](https://github.com/yandex/ClickHouse/pull/5642) ([alexey-milovidov](https://github.com/alexey-milovidov))
