- Updated the redaction policy for cluster settings in `debug zip` output. All "sensitive" settings are now redacted in all debug zips, whether or not redaction is explicitly requested. In redacted debug zips, both "sensitive" and "non-reportable" settings are redacted. This replaces the previous behavior, which redacted all string-type settings only in redacted debug zips. [#150364][#150364]

- Added a new file, `cluster_settings_history.txt`, to debug zips. This file contains a history of cluster setting changes based on the system event log table. The history is only available while the corresponding events remain in the table. Sensitive settings are always redacted, and non-reportable settings are redacted when the debug zip is generated with redaction enabled. [#151066][#151066]

During a major-version upgrade, certain features and performance improvements are not available until the upgrade is finalized. In v25.4, these are:

- **Partial statistics with constraining predicates**: The ability to manually create single-column partial statistics on boolean predicate expressions using a constraining `WHERE` clause in `CREATE STATISTICS` statements. For details, refer to the [release note](#v25-4-0-alpha-2-partial-statistics).
- **Changefeed span frontier persistence**: Changefeeds now periodically persist their entire span frontiers so that fewer duplicates need to be emitted during restarts. The default persistence interval is 30 seconds, configurable with the `changefeed.progress.frontier_persistence.interval` cluster setting. For details, refer to the [release note](#v25-4-0-alpha-2-changefeed-frontier-persistence).
