-# ClickHouse release 1.1.54385, 2018-06-01
+## ClickHouse release 18.5.1, 2018-07-31
-## Bug fixes:
+### New features:
+
+* Added the hash function `murmurHash2_32` [#2756](https://github.com/yandex/ClickHouse/pull/2756).
+
+### Improvements:
+
+* Now you can use the `from_env` attribute to set values in config files from environment variables [#2741](https://github.com/yandex/ClickHouse/pull/2741).
+* Added case-insensitive versions of the `coalesce`, `ifNull`, and `nullIf functions` [#2752](https://github.com/yandex/ClickHouse/pull/2752).
+
+### Bug fixes:
+
+* Fixed a possible bug when starting a replica [#2759](https://github.com/yandex/ClickHouse/pull/2759).
+
+## ClickHouse release 18.4.0, 2018-07-28
+
+### New features:
+
+* Added system tables: `formats`, `data_type_families`, `aggregate_function_combinators`, `table_functions`, `table_engines`, `collations` [#2721](https://github.com/yandex/ClickHouse/pull/2721).
+* Added the ability to use a table function instead of a table as an argument of a `remote` or `cluster` table function [#2708](https://github.com/yandex/ClickHouse/pull/2708).
+* Support for `HTTP Basic` authentication in the replication protocol [#2727](https://github.com/yandex/ClickHouse/pull/2727).
+* The `has` function now allows searching for a numeric value in an array of `Enum` values [Maxim Khrisanfov](https://github.com/yandex/ClickHouse/pull/2699).
+* Support for adding arbitrary message separators when reading from `Kafka` [Amos Bird](https://github.com/yandex/ClickHouse/pull/2701).
+
+### Improvements:
+
+* The `ALTER TABLE t DELETE WHERE` query does not rewrite data chunks that were not affected by the WHERE condition [#2694](https://github.com/yandex/ClickHouse/pull/2694).
+* The `use_minimalistic_checksums_in_zookeeper` option for `ReplicatedMergeTree` tables is enabled by default. This setting was added in version 1.1.54378, 2018-04-16. Versions that are older than 1.1.54378 can no longer be installed.
+* Support for running `KILL` and `OPTIMIZE` queries that specify `ON CLUSTER` [Winter Zhang](https://github.com/yandex/ClickHouse/pull/2689).
+
+### Bug fixes:
+
+* Fixed the error `Column ... is not under an aggregate function and not in GROUP BY` for aggregation with an IN expression. This bug appeared in version 18.1.0. ([bbdd780b](https://github.com/yandex/ClickHouse/commit/bbdd780be0be06a0f336775941cdd536878dd2c2))
+* Fixed a bug in the `windowFunnel` aggregate function [Winter Zhang](https://github.com/yandex/ClickHouse/pull/2735).
+* Fixed a bug in the `anyHeavy` aggregate function ([a2101df2](https://github.com/yandex/ClickHouse/commit/a2101df25a6a0fba99aa71f8793d762af2b801ee))
+* Fixed server crash when using the `countArray()` aggregate function.
+
+## ClickHouse release 18.1.0, 2018-07-23
+
+### New features:
+
+* Support for the `ALTER TABLE t DELETE WHERE` query for non-replicated MergeTree tables ([#2634](https://github.com/yandex/ClickHouse/pull/2634)).
+* Support for arbitrary types for the `uniq*` family of aggregate functions ([#2010](https://github.com/yandex/ClickHouse/issues/2010)).
+* Support for arbitrary types in comparison operators ([#2026](https://github.com/yandex/ClickHouse/issues/2026)).
+* The `users.xml` file allows setting a subnet mask in the format `10.0.0.1/255.255.255.0`. This is necessary for using masks for IPv6 networks with zeros in the middle ([#2637](https://github.com/yandex/ClickHouse/pull/2637)).
+* Added the `arrayDistinct` function ([#2670](https://github.com/yandex/ClickHouse/pull/2670)).
+* The SummingMergeTree engine can now work with AggregateFunction type columns ([Constantin S. Pan](https://github.com/yandex/ClickHouse/pull/2566)).
+
+### Improvements:
+
+* Changed the numbering scheme for release versions. Now the first part contains the year of release (A.D., Moscow timezone, minus 2000), the second part contains the number for major changes (increases for most releases), and the third part is the patch version. Releases are still backwards compatible, unless otherwise stated in the changelog.
+* Faster conversions of floating-point numbers to a string ([Amos Bird](https://github.com/yandex/ClickHouse/pull/2664)).
+* If some rows were skipped during an insert due to parsing errors (this is possible with the `input_allow_errors_num` and `input_allow_errors_ratio` settings enabled), the number of skipped rows is now written to the server log ([Leonardo Cecchi](https://github.com/yandex/ClickHouse/pull/2669)).
+
+### Bug fixes:
+
+* Fixed the TRUNCATE command for temporary tables ([Amos Bird](https://github.com/yandex/ClickHouse/pull/2624)).
+* Fixed a rare deadlock in the ZooKeeper client library that occurred when there was a network error while reading the response ([c315200](https://github.com/yandex/ClickHouse/commit/c315200e64b87e44bdf740707fc857d1fdf7e947)).
+* Fixed an error during a CAST to Nullable types ([#1322](https://github.com/yandex/ClickHouse/issues/1322)).
+* Fixed the incorrect result of the `maxIntersection()` function when the boundaries of intervals coincided ([Michael Furmur](https://github.com/yandex/ClickHouse/pull/2657)).
+* Fixed incorrect transformation of the OR expression chain in a function argument ([chenxing-xc](https://github.com/yandex/ClickHouse/pull/2663)).
+* Fixed performance degradation for queries containing `IN (subquery)` expressions inside another subquery ([#2571](https://github.com/yandex/ClickHouse/issues/2571)).
+* Fixed incompatibility between servers with different versions in distributed queries that use a `CAST` function that isn't in uppercase letters ([fe8c4d6](https://github.com/yandex/ClickHouse/commit/fe8c4d64e434cacd4ceef34faa9005129f2190a5)).
+* Added missing quoting of identifiers for queries to an external DBMS ([#2635](https://github.com/yandex/ClickHouse/issues/2635)).
+
+### Backward incompatible changes:
+
+* Converting a string containing the number zero to DateTime does not work. Example: `SELECT toDateTime('0')`. This is also the reason that `DateTime DEFAULT '0'` does not work in tables, as well as `0` in dictionaries. Solution: replace `0` with `0000-00-00 00:00:00`.
+
+
+## ClickHouse release 1.1.54394, 2018-07-12
+
+### New features:
+
+* Added the `histogram` aggregate function ([Mikhail Surin](https://github.com/yandex/ClickHouse/pull/2521)).
+* Now `OPTIMIZE TABLE ... FINAL` can be used without specifying partitions for `ReplicatedMergeTree` ([Amos Bird](https://github.com/yandex/ClickHouse/pull/2600)).
+
+### Bug fixes:
+
+* Fixed a problem with a very small timeout for sockets (one second) for reading and writing when sending and downloading replicated data, which made it impossible to download larger parts if there is a load on the network or disk (it resulted in cyclical attempts to download parts). This error occurred in version 1.1.54388.
+* Fixed issues when using chroot in ZooKeeper if you inserted duplicate data blocks in the table.
+* The `has` function now works correctly for an array with Nullable elements ([#2115](https://github.com/yandex/ClickHouse/issues/2115)).
+* The `system.tables` table now works correctly when used in distributed queries. The `metadata_modification_time` and `engine_full` columns are now non-virtual. Fixed an error that occurred if only these columns were requested from the table.
+* Fixed how an empty `TinyLog` table works after inserting an empty data block ([#2563](https://github.com/yandex/ClickHouse/issues/2563)).
+* The `system.zookeeper` table works if the value of the node in ZooKeeper is NULL.
+
+## ClickHouse release 1.1.54390, 2018-07-06
+
+### New features:
+
+* Queries can be sent in `multipart/form-data` format (in the `query` field), which is useful if external data is also sent for query processing ([Olga Hvostikova](https://github.com/yandex/ClickHouse/pull/2490)).
+* Added the ability to enable or disable processing single or double quotes when reading data in CSV format. You can configure this in the `format_csv_allow_single_quotes` and `format_csv_allow_double_quotes` settings ([Amos Bird](https://github.com/yandex/ClickHouse/pull/2574)).
+* Now `OPTIMIZE TABLE ... FINAL` can be used without specifying the partition for non-replicated variants of `MergeTree` ([Amos Bird](https://github.com/yandex/ClickHouse/pull/2599)).
+
+### Improvements:
+
+* Improved performance, reduced memory consumption, and correct tracking of memory consumption with use of the IN operator when a table index could be used ([#2584](https://github.com/yandex/ClickHouse/pull/2584)).
+* Removed redundant checking of checksums when adding a data part. This is important when there are a large number of replicas, because in these cases the total number of checks was equal to N^2.
+* Added support for `Array(Tuple(...))` arguments for the `arrayEnumerateUniq` function ([#2573](https://github.com/yandex/ClickHouse/pull/2573)).
+* Added `Nullable` support for the `runningDifference` function ([#2594](https://github.com/yandex/ClickHouse/pull/2594)).
+* Improved query analysis performance when there is a very large number of expressions ([#2572](https://github.com/yandex/ClickHouse/pull/2572)).
+* Faster selection of data parts for merging in `ReplicatedMergeTree` tables. Faster recovery of the ZooKeeper session ([#2597](https://github.com/yandex/ClickHouse/pull/2597)).
+* The `format_version.txt` file for `MergeTree` tables is re-created if it is missing, which makes sense if ClickHouse is launched after copying the directory structure without files ([Ciprian Hacman](https://github.com/yandex/ClickHouse/pull/2593)).
+
+### Bug fixes:
+
+* Fixed a bug when working with ZooKeeper that could make it impossible to recover the session and readonly states of tables before restarting the server.
+* Fixed a bug when working with ZooKeeper that could result in old nodes not being deleted if the session is interrupted.
+* Fixed an error in the `quantileTDigest` function for Float arguments (this bug was introduced in version 1.1.54388) ([Mikhail Surin](https://github.com/yandex/ClickHouse/pull/2553)).
+* Fixed a bug in the index for MergeTree tables if the primary key column is located inside the function for converting types between signed and unsigned integers of the same size ([#2603](https://github.com/yandex/ClickHouse/pull/2603)).
+* Fixed segfault if `macros` are used but they aren't in the config file ([#2570](https://github.com/yandex/ClickHouse/pull/2570)).
+* Fixed switching to the default database when reconnecting the client ([#2583](https://github.com/yandex/ClickHouse/pull/2583)).
+* Fixed a bug that occurred when the `use_index_for_in_with_subqueries` setting was disabled.
+
+### Security fix:
+
+* Sending files is no longer possible when connected to MySQL (`LOAD DATA LOCAL INFILE`).
+
+## ClickHouse release 1.1.54388, 2018-06-28
+
+### New features:
+
+* Support for the `ALTER TABLE t DELETE WHERE` query for replicated tables. Added the `system.mutations` table to track progress of this type of queries.
+* Support for the `ALTER TABLE t [REPLACE|ATTACH] PARTITION` query for MergeTree tables.
+* Support for the `TRUNCATE TABLE` query ([Winter Zhang](https://github.com/yandex/ClickHouse/pull/2260)).
+* Several new `SYSTEM` queries for replicated tables (`RESTART REPLICAS`, `SYNC REPLICA`, `[STOP|START] [MERGES|FETCHES|SENDS REPLICATED|REPLICATION QUEUES]`).
+* Added the ability to write to a table with the MySQL engine and the corresponding table function ([sundy-li](https://github.com/yandex/ClickHouse/pull/2294)).
+* Added the `url()` table function and the `URL` table engine ([Alexander Sapin](https://github.com/yandex/ClickHouse/pull/2501)).
+* Added the `windowFunnel` aggregate function ([sundy-li](https://github.com/yandex/ClickHouse/pull/2352)).
+* New `startsWith` and `endsWith` functions for strings ([Vadim Plakhtinsky](https://github.com/yandex/ClickHouse/pull/2429)).
+* The `numbers()` table function now allows you to specify the offset ([Winter Zhang](https://github.com/yandex/ClickHouse/pull/2535)).
+* The password to `clickhouse-client` can be entered interactively.
+* Server logs can now be sent to syslog ([Alexander Krasheninnikov](https://github.com/yandex/ClickHouse/pull/2459)).
+* Support for logging in dictionaries with a shared library source ([Alexander Sapin](https://github.com/yandex/ClickHouse/pull/2472)).
+* Support for custom CSV delimiters ([Ivan Zhukov](https://github.com/yandex/ClickHouse/pull/2263)).
+* Added the `date_time_input_format` setting. If you switch this setting to `'best_effort'`, DateTime values will be read in a wide range of formats.
+* Added the `clickhouse-obfuscator` utility for data obfuscation. Usage example: publishing data used in performance tests.
+
+### Experimental features:
+
+* Added the ability to calculate `and` arguments only where they are needed ([Anastasia Tsarkova](https://github.com/yandex/ClickHouse/pull/2272)).
+* JIT compilation to native code is now available for some expressions ([pyos](https://github.com/yandex/ClickHouse/pull/2277)).
+
+### Bug fixes:
+
+* Duplicates no longer appear for a query with `DISTINCT` and `ORDER BY`.
+* Queries with `ARRAY JOIN` and `arrayFilter` no longer return an incorrect result.
+* Fixed an error when reading an array column from a Nested structure ([#2066](https://github.com/yandex/ClickHouse/issues/2066)).
+* Fixed an error when analyzing queries with a HAVING section like `HAVING tuple IN (...)`.
+* Fixed an error when analyzing queries with recursive aliases.
+* Fixed an error when reading from ReplacingMergeTree with a condition in PREWHERE that filters all rows ([#2525](https://github.com/yandex/ClickHouse/issues/2525)).
+* User profile settings were not applied when using sessions in the HTTP interface.
+* Fixed how settings are applied from the command line parameters in `clickhouse-local`.
+* The ZooKeeper client library now uses the session timeout received from the server.
+* Fixed a bug in the ZooKeeper client library when the client waited for the server response longer than the timeout.
+* Fixed pruning of parts for queries with conditions on partition key columns ([#2342](https://github.com/yandex/ClickHouse/issues/2342)).
+* Merges are now possible after `CLEAR COLUMN IN PARTITION` ([#2315](https://github.com/yandex/ClickHouse/issues/2315)).
+* Type mapping in the ODBC table function has been fixed ([sundy-li](https://github.com/yandex/ClickHouse/pull/2268)).
+* Type comparisons have been fixed for `DateTime` with and without the time zone ([Alexander Bocharov](https://github.com/yandex/ClickHouse/pull/2400)).
+* Fixed syntactic parsing and formatting of the `CAST` operator.
+* Fixed insertion into a materialized view for the Distributed table engine ([Babacar Diassé](https://github.com/yandex/ClickHouse/pull/2411)).
+* Fixed a race condition when writing data from the `Kafka` engine to materialized views ([Yangkuan Liu](https://github.com/yandex/ClickHouse/pull/2448)).
+* Fixed SSRF in the `remote()` table function.
+* Fixed exit behavior of `clickhouse-client` in multiline mode ([#2510](https://github.com/yandex/ClickHouse/issues/2510)).
+
+### Improvements:
+
+* Background tasks in replicated tables are now performed in a thread pool instead of in separate threads ([Silviu Caragea](https://github.com/yandex/ClickHouse/pull/1722)).
+* Improved LZ4 compression performance.
+* Faster analysis for queries with a large number of JOINs and sub-queries.
+* The DNS cache is now updated automatically when there are too many network errors.
+* Table inserts no longer occur if the insert into one of the materialized views is not possible because it has too many parts.
+* Corrected the discrepancy in the event counters `Query`, `SelectQuery`, and `InsertQuery`.
+* Expressions like `tuple IN (SELECT tuple)` are allowed if the tuple types match.
+* A server with replicated tables can start even if you haven't configured ZooKeeper.
+* When calculating the number of available CPU cores, limits on cgroups are now taken into account ([Atri Sharma](https://github.com/yandex/ClickHouse/pull/2325)).
+* Added chown for config directories in the systemd config file ([Mikhail Shiryaev](https://github.com/yandex/ClickHouse/pull/2421)).
+
+### Build changes:
+
+* The gcc8 compiler can be used for builds.
+* Added the ability to build llvm from a submodule.
+* The version of the librdkafka library has been updated to v0.11.4.
+* Added the ability to use the system libcpuid library. The library version has been updated to 0.4.0.
+* Fixed the build using the vectorclass library ([Babacar Diassé](https://github.com/yandex/ClickHouse/pull/2274)).
+* Cmake now generates files for ninja by default (like when using `-G Ninja`).
+* Added the ability to use the libtinfo library instead of libtermcap ([Georgy Kondratiev](https://github.com/yandex/ClickHouse/pull/2519)).
+* Fixed a header file conflict in Fedora Rawhide ([#2520](https://github.com/yandex/ClickHouse/issues/2520)).
+
+### Backward incompatible changes:
+
+* Removed escaping in `Vertical` and `Pretty*` formats and deleted the `VerticalRaw` format.
+* If servers with version 1.1.54388 (or newer) and servers with older version are used simultaneously in distributed query and the query has `cast(x, 'Type')` expression in the form without `AS` keyword and with `cast` not in uppercase, then the exception with message like `Not found column cast(0, 'UInt8') in block` will be thrown. Solution: update server on all cluster nodes.

* Renamed packages: `clickhouse-server-base` is now `clickhouse-common-static`; `clickhouse-server-common` is now `clickhouse-server`; `clickhouse-common-dbg` is now `clickhouse-common-static-dbg`. To install, use `clickhouse-server clickhouse-client`. Packages with the old names will still load in the repositories for backward compatibility.
-## Backward-incompatible changes:
+### Backward-incompatible changes:
* Removed the special interpretation of an IN expression if an array is specified on the left side. Previously, the expression `arr IN (set)` was interpreted as "at least one `arr` element belongs to the `set`". To get the same behavior in the new version, write `arrayExists(x -> x IN (set), arr)`.
* Disabled the incorrect use of the socket option `SO_REUSEPORT`, which was incorrectly enabled by default in the Poco library. Note that on Linux there is no longer any reason to simultaneously specify the addresses `::` and `0.0.0.0` for listen – use just `::`, which allows listening to the connection both over IPv4 and IPv6 (with the default kernel config settings). You can also revert to the behavior from previous versions by specifying `1` in the config.

* There is now a higher default value for the MergeTree setting `max_bytes_to_merge_at_max_space_in_pool` (the maximum total size of data parts to merge, in bytes): it has increased from 100 GiB to 150 GiB. This might result in large merges running after the server upgrade, which could cause an increased load on the disk subsystem. If the free space available on the server is less than twice the total amount of the merges that are running, this will cause all other merges to stop running, including merges of small data parts. As a result, INSERT requests will fail with the message "Merges are processing significantly slower than inserts." Use the `SELECT * FROM system.merges` request to monitor the situation. You can also check the `DiskSpaceReservedForMerge` metric in the `system.metrics` table, or in Graphite. You don't need to do anything to fix this, since the issue will resolve itself once the large merges finish. If you find this unacceptable, you can restore the previous value for the `max_bytes_to_merge_at_max_space_in_pool` setting (to do this, go to the `` section in config.xml, set `107374182400` and restart the server).

+* Поддержка запроса `ALTER TABLE t DELETE WHERE` для нереплицированных MergeTree-таблиц ([#2634](https://github.com/yandex/ClickHouse/pull/2634)).
+* Поддержка произвольных типов для семейства агрегатных функций `uniq*` ([#2010](https://github.com/yandex/ClickHouse/issues/2010)).
+* Поддержка произвольных типов в операторах сравнения ([#2026](https://github.com/yandex/ClickHouse/issues/2026)).
+* Возможность в `users.xml` указывать маску подсети в формате `10.0.0.1/255.255.255.0`. Это необходимо для использования "дырявых" масок IPv6 сетей ([#2637](https://github.com/yandex/ClickHouse/pull/2637)).
+* Добавлена функция `arrayDistinct` ([#2670](https://github.com/yandex/ClickHouse/pull/2670)).
+* Движок SummingMergeTree теперь может работать со столбцами типа AggregateFunction ([Constantin S. Pan](https://github.com/yandex/ClickHouse/pull/2566)).
+
+### Улучшения:
+* Изменена схема версионирования релизов. Теперь первый компонент содержит год релиза (A.D.; по московскому времени; из номера вычитается 2000), второй - номер крупных изменений (увеличивается для большинства релизов), третий - патч-версия. Релизы по-прежнему обратно совместимы, если другое не указано в changelog.
+* Ускорено преобразование чисел с плавающей точкой в строку ([Amos Bird](https://github.com/yandex/ClickHouse/pull/2664)).
+* Теперь, если при вставке из-за ошибок парсинга пропущено некоторое количество строк (такое возможно про включённых настройках `input_allow_errors_num`, `input_allow_errors_ratio`), это количество пишется в лог сервера ([Leonardo Cecchi](https://github.com/yandex/ClickHouse/pull/2669)).
+
+### Исправление ошибок:
+* Исправлена работа команды TRUNCATE для временных таблиц ([Amos Bird](https://github.com/yandex/ClickHouse/pull/2624)).
+* Исправлен редкий deadlock в клиентской библиотеке ZooKeeper, который возникал при сетевой ошибке во время вычитывания ответа ([c315200](https://github.com/yandex/ClickHouse/commit/c315200e64b87e44bdf740707fc857d1fdf7e947)).
+* Исправлена ошибка при CAST в Nullable типы ([#1322](https://github.com/yandex/ClickHouse/issues/1322)).
+* Исправлен неправильный результат функции `maxIntersection()` в случае совпадения границ отрезков ([Michael Furmur](https://github.com/yandex/ClickHouse/pull/2657)).
+* Исправлено неверное преобразование цепочки OR-выражений в аргументе функции ([chenxing-xc](https://github.com/yandex/ClickHouse/pull/2663)).
+* Исправлена деградация производительности запросов, содержащих выражение `IN (подзапрос)` внутри другого подзапроса ([#2571](https://github.com/yandex/ClickHouse/issues/2571)).
+* Исправлена несовместимость серверов разных версий при распределённых запросах, использующих функцию `CAST` не в верхнем регистре ([fe8c4d6](https://github.com/yandex/ClickHouse/commit/fe8c4d64e434cacd4ceef34faa9005129f2190a5)).
+* Добавлено недостающее квотирование идентификаторов при запросах к внешним СУБД ([#2635](https://github.com/yandex/ClickHouse/issues/2635)).
+
+### Обратно несовместимые изменения:
+* Не работает преобразование строки, содержащей число ноль, в DateTime. Пример: `SELECT toDateTime('0')`. По той же причине не работает `DateTime DEFAULT '0'` в таблицах, а также `0` в словарях. Решение: заменить `0` на `0000-00-00 00:00:00`.
+
+
+## ClickHouse release 1.1.54394, 2018-07-12
+
+### Новые возможности:
+* Добавлена агрегатная функция `histogram` ([Михаил Сурин](https://github.com/yandex/ClickHouse/pull/2521)).
+* Возможность использования `OPTIMIZE TABLE ... FINAL` без указания партиции для `ReplicatedMergeTree` ([Amos Bird](https://github.com/yandex/ClickHouse/pull/2600)).
+
+### Исправление ошибок:
+* Исправлена ошибка - выставление слишком маленького таймаута у сокетов (одна секунда) для чтения и записи при отправке и скачивании реплицируемых данных, что приводило к невозможности скачать куски достаточно большого размера при наличии некоторой нагрузки на сеть или диск (попытки скачивания кусков циклически повторяются). Ошибка возникла в версии 1.1.54388.
+* Исправлена работа при использовании chroot в ZooKeeper, в случае вставки дублирующихся блоков данных в таблицу.
+* Исправлена работа функции `has` для случая массива с Nullable элементами ([#2115](https://github.com/yandex/ClickHouse/issues/2521)).
+* Исправлена работа таблицы `system.tables` при её использовании в распределённых запросах; столбцы `metadata_modification_time` и `engine_full` сделаны невиртуальными; исправлена ошибка в случае, если из таблицы были запрошены только эти столбцы.
+* Исправлена работа пустой таблицы типа `TinyLog` после вставки в неё пустого блока данных ([#2563](https://github.com/yandex/ClickHouse/issues/2563)).
+* Таблица `system.zookeeper` работает в случае, если значение узла в ZooKeeper равно NULL.
+
+
+## ClickHouse release 1.1.54390, 2018-07-06
+
+### Новые возможности:
+* Возможность отправки запроса в формате `multipart/form-data` (в поле `query`), что полезно, если при этом также отправляются внешние данные для обработки запроса ([Ольга Хвостикова](https://github.com/yandex/ClickHouse/pull/2490)).
+* Добавлена возможность включить или отключить обработку одинарных или двойных кавычек при чтении данных в формате CSV. Это задаётся настройками `format_csv_allow_single_quotes` и `format_csv_allow_double_quotes` ([Amos Bird](https://github.com/yandex/ClickHouse/pull/2574))
+* Возможность использования `OPTIMIZE TABLE ... FINAL` без указания партиции для не реплицированных вариантов`MergeTree` ([Amos Bird](https://github.com/yandex/ClickHouse/pull/2599)).
+
+### Улучшения:
+* Увеличена производительность, уменьшено потребление памяти, добавлен корректный учёт потребления памяти, при использовании оператора IN в случае, когда для его работы может использоваться индекс таблицы ([#2584](https://github.com/yandex/ClickHouse/pull/2584)).
+* Убраны избыточные проверки чексумм при добавлении куска. Это важно в случае большого количества реплик, так как в этом случае суммарное количество проверок было равно N^2.
+* Добавлена поддержка аргументов типа `Array(Tuple(...))` для функции `arrayEnumerateUniq` ([#2573](https://github.com/yandex/ClickHouse/pull/2573)).
+* Добавлена поддержка `Nullable` для функции `runningDifference`. ([#2594](https://github.com/yandex/ClickHouse/pull/2594))
+* Увеличена производительность анализа запроса в случае очень большого количества выражений ([#2572](https://github.com/yandex/ClickHouse/pull/2572)).
+* Более быстрый выбор кусков для слияния в таблицах типа `ReplicatedMergeTree`. Более быстрое восстановление сессии с ZooKeeper. ([#2597](https://github.com/yandex/ClickHouse/pull/2597)).
+* Файл `format_version.txt` для таблиц семейства `MergeTree` создаётся заново при его отсутствии, что имеет смысл в случае запуска ClickHouse после копирования структуры директорий без файлов ([Ciprian Hacman](https://github.com/yandex/ClickHouse/pull/2593)).
+
+### Исправление ошибок:
+* Исправлена ошибка при работе с ZooKeeper, которая могла приводить к невозможности восстановления сессии и readonly состояниям таблиц до перезапуска сервера.
+* Исправлена ошибка при работе с ZooKeeper, которая могла приводить к неудалению старых узлов при разрыве сессии.
+* Исправлена ошибка в функции `quantileTDigest` для Float аргументов (ошибка появилась в версии 1.1.54388) ([Михаил Сурин](https://github.com/yandex/ClickHouse/pull/2553)).
+* Исправлена ошибка работы индекса таблиц типа MergeTree, если в условии, столбец первичного ключа расположен внутри функции преобразования типов между знаковым и беззнаковым целым одного размера ([#2603](https://github.com/yandex/ClickHouse/pull/2603)).
+* Исправлен segfault, если в конфигурационном файле нет `macros`, но они используются ([#2570](https://github.com/yandex/ClickHouse/pull/2570)).
+* Исправлено переключение на базу данных по-умолчанию при переподключении клиента ([#2583](https://github.com/yandex/ClickHouse/pull/2583)).
+* Исправлена ошибка в случае отключенной настройки `use_index_for_in_with_subqueries`.
+
+### Исправления безопасности:
+* При соединениях с MySQL удалена возможность отправки файлов (`LOAD DATA LOCAL INFILE`).
+
+
+## ClickHouse release 1.1.54388, 2018-06-28
+
+### Новые возможности:
+* Добавлена поддержка запроса `ALTER TABLE t DELETE WHERE` для реплицированных таблиц и таблица `system.mutations`.
+* Добавлена поддержка запроса `ALTER TABLE t [REPLACE|ATTACH] PARTITION` для *MergeTree-таблиц.
+* Добавлена поддержка запроса `TRUNCATE TABLE` ([Winter Zhang](https://github.com/yandex/ClickHouse/pull/2260))
+* Добавлено несколько новых `SYSTEM`-запросов для реплицированных таблиц (`RESTART REPLICAS`, `SYNC REPLICA`, `[STOP|START] [MERGES|FETCHES|REPLICATED SENDS|REPLICATION QUEUES]`).
+* Добавлена возможность записи в таблицу с движком MySQL и соответствующую табличную функцию ([sundy-li](https://github.com/yandex/ClickHouse/pull/2294)).
+* Добавлена табличная функция `url()` и движок таблиц `URL` ([Александр Сапин](https://github.com/yandex/ClickHouse/pull/2501)).
+* Добавлена агрегатная функция `windowFunnel` ([sundy-li](https://github.com/yandex/ClickHouse/pull/2352)).
+* Добавлены функции `startsWith` и `endsWith` для строк ([Вадим Плахтинский](https://github.com/yandex/ClickHouse/pull/2429)).
+* В табличной функции `numbers()` добавлена возможность указывать offset ([Winter Zhang](https://github.com/yandex/ClickHouse/pull/2535)).
+* Добавлена возможность интерактивного ввода пароля в `clickhouse-client`.
+* Добавлена возможность отправки логов сервера в syslog ([Александр Крашенинников](https://github.com/yandex/ClickHouse/pull/2459)).
+* Добавлена поддержка логирования в словарях с источником shared library ([Александр Сапин](https://github.com/yandex/ClickHouse/pull/2472)).
+* Добавлена поддержка произвольного разделителя в формате CSV ([Иван Жуков](https://github.com/yandex/ClickHouse/pull/2263))
+* Добавлена настройка `date_time_input_format`. Если переключить эту настройку в значение `'best_effort'`, значения DateTime будут читаться в широком диапазоне форматов.
+* Добавлена утилита `clickhouse-obfuscator` для обфускации данных. Пример использования: публикация данных, используемых в тестах производительности.
+
+### Экспериментальные возможности:
+* Добавлена возможность вычислять аргументы функции `and` только там, где они нужны ([Анастасия Царькова](https://github.com/yandex/ClickHouse/pull/2272))
+* Добавлена возможность JIT-компиляции в нативный код некоторых выражений ([pyos](https://github.com/yandex/ClickHouse/pull/2277)).
+
+### Исправление ошибок:
+* Исправлено появление дублей в запросе с `DISTINCT` и `ORDER BY`.
+* Запросы с `ARRAY JOIN` и `arrayFilter` раньше возвращали некорректный результат.
+* Исправлена ошибка при чтении столбца-массива из Nested-структуры ([#2066](https://github.com/yandex/ClickHouse/issues/2066)).
+* Исправлена ошибка при анализе запросов с секцией HAVING вида `HAVING tuple IN (...)`.
+* Исправлена ошибка при анализе запросов с рекурсивными алиасами.
+* Исправлена ошибка при чтении из ReplacingMergeTree с условием в PREWHERE, фильтрующим все строки ([#2525](https://github.com/yandex/ClickHouse/issues/2525)).
+* Настройки профиля пользователя не применялись при использовании сессий в HTTP-интерфейсе.
+* Исправлено применение настроек из параметров командной строки в программе clickhouse-local.
+* Клиентская библиотека ZooKeeper теперь использует таймаут сессии, полученный от сервера.
+* Исправлена ошибка в клиентской библиотеке ZooKeeper, из-за которой ожидание ответа от сервера могло длиться дольше таймаута.
+* Исправлено отсечение ненужных кусков при запросе с условием на столбцы ключа партиционирования ([#2342](https://github.com/yandex/ClickHouse/issues/2342)).
+* После `CLEAR COLUMN IN PARTITION` в соответствующей партиции теперь возможны слияния ([#2315](https://github.com/yandex/ClickHouse/issues/2315)).
+* Исправлено соответствие типов в табличной функции ODBC ([sundy-li](https://github.com/yandex/ClickHouse/pull/2268)).
+* Исправлено некорректное сравнение типов `DateTime` с таймзоной и без неё ([Александр Бочаров](https://github.com/yandex/ClickHouse/pull/2400)).
+* Исправлен синтаксический разбор и форматирование оператора `CAST`.
+* Исправлена вставка в материализованное представление в случае, если движок таблицы представления - Distributed ([Babacar Diassé](https://github.com/yandex/ClickHouse/pull/2411)).
+* Исправлен race condition при записи данных из движка `Kafka` в материализованные представления ([Yangkuan Liu](https://github.com/yandex/ClickHouse/pull/2448)).
+* Исправлена SSRF в табличной функции remote().
+* Исправлен выход из `clickhouse-client` в multiline-режиме ([#2510](https://github.com/yandex/ClickHouse/issues/2510)).
+
+### Улучшения:
+* Фоновые задачи в реплицированных таблицах теперь выполняются не в отдельных потоках, а в пуле потоков ([Silviu Caragea](https://github.com/yandex/ClickHouse/pull/1722))
+* Улучшена производительность разжатия LZ4.
+* Ускорен анализ запроса с большим числом JOIN-ов и подзапросов.
+* DNS-кэш теперь автоматически обновляется при большом числе сетевых ошибок.
+* Вставка в таблицу теперь не происходит, если вставка в одно из её материализованных представлений невозможна из-за того, что в нём много кусков.
+* Исправлено несоответствие в значениях счётчиков событий `Query`, `SelectQuery`, `InsertQuery`.
+* Разрешены выражения вида `tuple IN (SELECT tuple)`, если типы кортежей совпадают.
+* Сервер с реплицированными таблицами теперь может стартовать, даже если не сконфигурирован ZooKeeper.
+* При расчёте количества доступных ядер CPU теперь учитываются ограничения cgroups ([Atri Sharma](https://github.com/yandex/ClickHouse/pull/2325)).
+* Добавлен chown директорий конфигов в конфигурационном файле systemd ([Михаил Ширяев](https://github.com/yandex/ClickHouse/pull/2421)).
+
+### Изменения сборки:
+* Добавлена возможность сборки компилятором gcc8.
+* Добавлена возможность сборки llvm из submodule.
+* Используемая версия библиотеки librdkafka обновлена до v0.11.4.
+* Добавлена возможность использования библиотеки libcpuid из системы, используемая версия библиотеки обновлена до 0.4.0.
+* Исправлена сборка с использованием библиотеки vectorclass ([Babacar Diassé](https://github.com/yandex/ClickHouse/pull/2274)).
+* Cmake теперь по умолчанию генерирует файлы для ninja (как при использовании `-G Ninja`).
+* Добавлена возможность использования библиотеки libtinfo вместо libtermcap ([Георгий Кондратьев](https://github.com/yandex/ClickHouse/pull/2519)).
+* Исправлен конфликт заголовочных файлов в Fedora Rawhide ([#2520](https://github.com/yandex/ClickHouse/issues/2520)).
+
+### Обратно несовместимые изменения:
+* Убран escaping в форматах `Vertical` и `Pretty*`, удалён формат `VerticalRaw`.
+* Если в распределённых запросах одновременно участвуют серверы версии 1.1.54388 или новее и более старые, то при использовании выражения `cast(x, 'Type')`, записанного без указания `AS`, если слово `cast` указано не в верхнем регистре, возникает ошибка вида `Not found column cast(0, 'UInt8') in block`. Решение: обновить сервер на всём кластере.

* Отключено ошибочное использование опции сокета `SO_REUSEPORT` (которая по ошибке включена по-умолчанию в библиотеке Poco). Стоит обратить внимание, что на Linux системах теперь не имеет смысла указывать одновременно адреса `::` и `0.0.0.0` для listen - следует использовать лишь адрес `::`, который (с настройками ядра по-умолчанию) позволяет слушать соединения как по IPv4 так и по IPv6.

Это может привести к запуску больших мержей после обновления сервера, что может вызвать повышенную нагрузку на дисковую подсистему. Если же на серверах, где это происходит, количество свободного места менее чем в два раза больше суммарного объёма выполняющихся мержей, то в связи с этим перестанут выполняться какие-либо другие мержи, включая мержи мелких кусков. Это приведёт к тому, что INSERT-ы будут отклоняться с сообщением "Merges are processing significantly slower than inserts". Для наблюдения, используйте запрос `SELECT * FROM system.merges`. Вы также можете смотреть на метрику `DiskSpaceReservedForMerge` в таблице `system.metrics` или в Graphite. Для исправления этой ситуации можно ничего не делать, так как она нормализуется сама после завершения больших мержей. Если же вас это не устраивает, вы можете вернуть настройку `max_bytes_to_merge_at_max_space_in_pool` в старое значение, прописав в config.xml в секции `` `107374182400` и перезапустить сервер.
