2024 Changelog

ClickHouse release v24.3.3.102-lts (7e7f3bdd9b) FIXME as compared to v24.3.2.23-lts (8b7d910960)

Improvement

• Backported in #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. #61972 (vdimir).
• Backported in #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 (Sema Checherinda).
• Backported in #62666: S3 storage and backups also need the same default keep alive settings as s3 disk. #62648 (Sema Checherinda).
