 - In v25.1, automatic partial statistics collection was enabled by default (by setting the `sql.stats.automatic_partial_collection.enabled` cluster setting to `true`). Partial statistics collection may encounter certain expected scenarios that were previously reported as failed stats jobs with PostgreSQL error code `55000`. These errors are benign and are no longer reported. Instead, the stats job will be marked as "succeeded," though no new statistics will be created.

 - Fixed a slow memory leak that was introduced in v25.1.8, v25.2.1, v25.2.2, and v25.3 betas. The leak would accumulate whenever a node executed a part of the distributed plan (the gateway node of the plan was not affected), and could only be mitigated by restarting the node.

 - Fixed the following bugs in the **Schedules** page of the DB Console:
     - Where the **Schedules** page displayed only a subset of a cluster's schedules. The **Schedules** page now correctly displays all schedules.
     - Where manually updating the `show` or `status` parameters in the URL (e.g., `http://127.0.0.1:8080/#/schedules?status=ACTIVE&show=50`) caused the **Schedules** page to fail to load.
