+
+### ClickHouse release v23.7.2.25-stable (8dd1107b032) FIXME as compared to v23.7.1.2470-stable (a70127baecc)
+
+#### Backward Incompatible Change
+* Backported in [#52850](https://github.com/ClickHouse/ClickHouse/issues/52850): If a dynamic disk contains a name, it should be specified as `disk = disk(name = 'disk_name'`, ...) in disk function arguments. In previous version it could be specified as `disk = disk_<disk_name>(...)`, which is no longer supported. [#52820](https://github.com/ClickHouse/ClickHouse/pull/52820) ([Kseniia Sumarokova](https://github.com/kssenii)).
+
+#### Build/Testing/Packaging Improvement
+* Backported in [#52913](https://github.com/ClickHouse/ClickHouse/issues/52913): Add `clickhouse-keeper-client` symlink to the clickhouse-server package. [#51882](https://github.com/ClickHouse/ClickHouse/pull/51882) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+
+#### Bug Fix (user-visible misbehavior in an official stable release)
+
+* Fix binary arithmetic for Nullable(IPv4) [#51642](https://github.com/ClickHouse/ClickHouse/pull/51642) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
+* Support IPv4 and IPv6 as dictionary attributes [#51756](https://github.com/ClickHouse/ClickHouse/pull/51756) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
+* init and destroy ares channel on demand.. [#52634](https://github.com/ClickHouse/ClickHouse/pull/52634) ([Arthur Passos](https://github.com/arthurpassos)).
+* Fix crash in function `tuple` with one sparse column argument [#52659](https://github.com/ClickHouse/ClickHouse/pull/52659) ([Anton Popov](https://github.com/CurtizJ)).
+* Fix data race in Keeper reconfiguration [#52804](https://github.com/ClickHouse/ClickHouse/pull/52804) ([Antonio Andelic](https://github.com/antonio2368)).
+* clickhouse-keeper: fix implementation of server with poll() [#52833](https://github.com/ClickHouse/ClickHouse/pull/52833) ([Andy Fiddaman](https://github.com/citrus-it)).
+
+#### NOT FOR CHANGELOG / INSIGNIFICANT
+
+* Rename setting disable_url_encoding to enable_url_encoding and add a test [#52656](https://github.com/ClickHouse/ClickHouse/pull/52656) ([Kruglov Pavel](https://github.com/Avogar)).
+* Fix bugs and better test for SYSTEM STOP LISTEN [#52680](https://github.com/ClickHouse/ClickHouse/pull/52680) ([Nikolay Degterinsky](https://github.com/evillique)).
+* Increase min protocol version for sparse serialization [#52835](https://github.com/ClickHouse/ClickHouse/pull/52835) ([Anton Popov](https://github.com/CurtizJ)).
+* Docker improvements [#52869](https://github.com/ClickHouse/ClickHouse/pull/52869) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).

 ## Mutations
 
 `ALTER` queries that are intended to manipulate table data are implemented with a mechanism called “mutations”, most notably [ALTER TABLE … DELETE](/docs/en/sql-reference/statements/alter/delete.md) and [ALTER TABLE … UPDATE](/docs/en/sql-reference/statements/alter/update.md). They are asynchronous background processes similar to merges in [MergeTree](/docs/en/engines/table-engines/mergetree-family/index.md) tables that to produce new “mutated” versions of parts.
