# 2024 Changelog

### ClickHouse release v24.3.3.102-lts (7e7f3bdd9be) FIXME as compared to v24.3.2.23-lts (8b7d910960c)

#### Improvement
* Backported in [#62188](https://github.com/ClickHouse/ClickHouse/issues/62188): StorageJoin with strictness `ANY` is consistent after reload. When several rows with the same key are inserted, the first one will have higher priority (before, it was chosen randomly upon table loading). close [#51027](https://github.com/ClickHouse/ClickHouse/issues/51027). [#61972](https://github.com/ClickHouse/ClickHouse/pull/61972) ([vdimir](https://github.com/vdimir)).
* Backported in [#62443](https://github.com/ClickHouse/ClickHouse/issues/62443): Client has to send header 'Keep-Alive: timeout=X' to the server. If a client receives a response from the server with that header, client has to use the value from the server. Also for a client it is better not to use a connection which is nearly expired in order to avoid connection close race. [#62249](https://github.com/ClickHouse/ClickHouse/pull/62249) ([Sema Checherinda](https://github.com/CheSema)).
* Backported in [#62666](https://github.com/ClickHouse/ClickHouse/issues/62666): S3 storage and backups also need the same default keep alive settings as s3 disk. [#62648](https://github.com/ClickHouse/ClickHouse/pull/62648) ([Sema Checherinda](https://github.com/CheSema)).

#### Build/Testing/Packaging Improvement
