# 2024 Changelog
|
||
|
||
### ClickHouse release v24.8.8.17-lts (81036bd118b) FIXME as compared to v24.8.7.41-lts (e28553d4f2b)
|
||
|
||
#### Improvement
|
||
* Backported in [#72060](https://github.com/ClickHouse/ClickHouse/issues/72060): When retrieving data directly from a dictionary using Dictionary storage, dictionary table function, or direct SELECT from the dictionary itself, it is now enough to have `SELECT` permission or `dictGet` permission for the dictionary. This aligns with previous attempts to prevent ACL bypasses: https://github.com/ClickHouse/ClickHouse/pull/57362 and https://github.com/ClickHouse/ClickHouse/pull/65359. It also makes the latter one backward compatible. [#72051](https://github.com/ClickHouse/ClickHouse/pull/72051) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).

|
||
#### Bug Fix (user-visible misbehavior in an official stable release)
|
||
* Backported in [#71981](https://github.com/ClickHouse/ClickHouse/issues/71981): After [this issue](https://github.com/ClickHouse/ClickHouse/pull/59946#issuecomment-1943653197) there are quite a few table replicas in production such that their `metadata_version` node value is both equal to `0` and is different from the respective table's `metadata` node version. This leads to `alter` queries failing on such replicas. [#69274](https://github.com/ClickHouse/ClickHouse/pull/69274) ([Miсhael Stetsyuk](https://github.com/mstetsyuk)).
|
||
* Backported in [#72142](https://github.com/ClickHouse/ClickHouse/issues/72142): Acquiring zero-copy shared lock before moving a part to zero-copy disk to prevent possible data loss if Keeper is unavailable. [#71845](https://github.com/ClickHouse/ClickHouse/pull/71845) ([Aleksei Filatov](https://github.com/aalexfvk)).
|
||
* Backported in [#72038](https://github.com/ClickHouse/ClickHouse/issues/72038): Fix exception for toDayOfWeek on WHERE condition with primary key of DateTime64 type. [#71849](https://github.com/ClickHouse/ClickHouse/pull/71849) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
|
||
* Backported in [#72032](https://github.com/ClickHouse/ClickHouse/issues/72032): Fix `Illegal type` error for `MergeTree` tables with binary monotonic function in `ORDER BY` when the first argument is constant. Fixes [#71941](https://github.com/ClickHouse/ClickHouse/issues/71941). [#71966](https://github.com/ClickHouse/ClickHouse/pull/71966) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
|
||
* Backported in [#72155](https://github.com/ClickHouse/ClickHouse/issues/72155): Allow only SELECT queries in EXPLAIN AST used inside subquery. Other types of queries lead to logical error: 'Bad cast from type DB::ASTCreateQuery to DB::ASTSelectWithUnionQuery' or `Inconsistent AST formatting`. [#71982](https://github.com/ClickHouse/ClickHouse/pull/71982) ([Pavel Kruglov](https://github.com/Avogar)).
|
||
* Backported in [#72114](https://github.com/ClickHouse/ClickHouse/issues/72114): Fix formatting of `MOVE PARTITION ... TO TABLE ...` alter commands when `format_alter_commands_with_parentheses` is enabled. [#72080](https://github.com/ClickHouse/ClickHouse/pull/72080) ([János Benjamin Antal](https://github.com/antaljanosbenjamin)).
