+### ClickHouse release v22.12.2.25-stable (c790cfd4465) FIXME as compared to v22.12.1.1752-stable (688e488e930)
+
+#### Build/Testing/Packaging Improvement
+* Backported in [#44381](https://github.com/ClickHouse/ClickHouse/issues/44381): In rare cases, we don't rebuild binaries, because another task with a similar prefix succeeded. E.g. `binary_darwin` didn't restart because `binary_darwin_aarch64`. [#44311](https://github.com/ClickHouse/ClickHouse/pull/44311) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+* Backported in [#44561](https://github.com/ClickHouse/ClickHouse/issues/44561): Retry the integration tests on compressing errors. [#44529](https://github.com/ClickHouse/ClickHouse/pull/44529) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+
+#### Bug Fix (user-visible misbehavior in official stable or prestable release)
+
+* Backported in [#44739](https://github.com/ClickHouse/ClickHouse/issues/44739): [#40651](https://github.com/ClickHouse/ClickHouse/issues/40651) [#41404](https://github.com/ClickHouse/ClickHouse/issues/41404). [#42126](https://github.com/ClickHouse/ClickHouse/pull/42126) ([Alexander Gololobov](https://github.com/davenger)).
+* Backported in [#44764](https://github.com/ClickHouse/ClickHouse/issues/44764): Fix parsing of bad version from compatibility setting. [#44224](https://github.com/ClickHouse/ClickHouse/pull/44224) ([Kruglov Pavel](https://github.com/Avogar)).
+* Backported in [#44435](https://github.com/ClickHouse/ClickHouse/issues/44435): Fix possible crash in case function `IN` with constant arguments was used as a constant argument together with `LowCardinality`. Fixes [#44221](https://github.com/ClickHouse/ClickHouse/issues/44221). [#44346](https://github.com/ClickHouse/ClickHouse/pull/44346) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
+
+#### NOT FOR CHANGELOG / INSIGNIFICANT
+
+* Bump libdivide (to gain some new optimizations) [#44132](https://github.com/ClickHouse/ClickHouse/pull/44132) ([Azat Khuzhin](https://github.com/azat)).
+* Add some settings under `compatibility` [#44209](https://github.com/ClickHouse/ClickHouse/pull/44209) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Fix deadlock in StorageSystemDatabases [#44272](https://github.com/ClickHouse/ClickHouse/pull/44272) ([Alexander Tokmakov](https://github.com/tavplubix)).
+* Get rid of global Git object [#44273](https://github.com/ClickHouse/ClickHouse/pull/44273) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+* Add check for submodules sanity [#44386](https://github.com/ClickHouse/ClickHouse/pull/44386) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+* Implement a custom central checkout action [#44399](https://github.com/ClickHouse/ClickHouse/pull/44399) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+* Fix crash on delete from materialized view [#44705](https://github.com/ClickHouse/ClickHouse/pull/44705) ([Alexander Gololobov](https://github.com/davenger)).
