- The FE ID generator strategy has been switched to a time-based approach, and IDs no longer start from 10000. [#44790](https://github.com/apache/doris/pull/44790)

- The `show cache hotspot` statement has been disabled in compute-storage separation mode, and direct access to system tables is required. [#47332](https://github.com/apache/doris/pull/47332)
