+<h3 id="v25-4-7-command-line-changes">Command-line changes</h3>
+
+- The `cockroach debug zip` command's `--include-files` and `--exclude-files` flags now support full zip path patterns. Patterns containing `/` are matched against the full path within the zip archive (e.g., `--include-files='debug/nodes/1/*.json'`). Patterns without `/` continue to match the base file name as before. [#164149][#164149]
+
+<h3 id="v25-4-7-bug-fixes">Bug fixes</h3>
+
+- Fixed a bug that prevented the `optimizer_min_row_count` setting from applying to anti-join expressions, which could lead to bad query plans. The fix is gated behind `optimizer_use_min_row_count_anti_join_fix`, which is on by default on v26.2 and later, and off by default in earlier versions. [#164799][#164799]
+- Fixed a bug where CockroachDB did not always promptly respond to the statement timeout when performing a hash join with an `ON` filter that is mostly `false`. [#164890][#164890]
+- Fixed a bug introduced in v25.4 where setting `min_checkpoint_frequency` to `0` prevented changefeeds from advancing their resolved timestamp (high-water mark) and emitting resolved messages. Note that setting `min_checkpoint_frequency` lower than `500ms` is not recommended as it may cause degraded changefeed performance. [#164894][#164894]
+- Lowered the default value of the `changefeed.max_retry_backoff` cluster setting from `10m` to `30s` to reduce changefeed lag during rolling restarts. [#164935][#164935]
+- Fixed a bug that could cause row sampling for table statistics to crash a node due to a data race when processing a collated string column with values larger than 400 bytes. This bug has existed since before v23.1. [#165566][#165566]
+- Fixed a bug in the legacy schema changer where rolling back a `CREATE TABLE` with inline `FOREIGN KEY` constraints could leave orphaned foreign key back-references on the referenced table, causing descriptor validation errors. [#166197][#166197]
+- Fixed a bug where rolling back a `CREATE TABLE` that referenced user-defined types or sequences would leave orphaned back-references on the type and sequence descriptors, causing them to appear in `crdb_internal.invalid_objects` after the table was GC'd. [#166225][#166225]
