+<h3 id="v26-1-2-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. [#164146][#164146]
+
+<h3 id="v26-1-2-bug-fixes">Bug fixes</h3>
+
+- Fixed a bug where contention events reported
+  the wrong key. Previously, the key field in contention events showed
+  the transaction's anchor key (used for record placement) rather than
+  the actual key where the conflict occurred. This made it difficult to
+  diagnose contention issues accurately.
+
+  Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> [#164157][#164157]
+- Fixed a bug where `CREATE INDEX` on a table with `PARTITION ALL BY` would fail if the partition columns were explicitly included in the primary key definition. [#164754][#164754]
+- 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. [#164798][#164798]
+- Fixed a bug where CockroachDB did not always promptly respond to the statement timeout when performing a hash join with `ON` filter that is mostly `false`. [#164891][#164891]
+- 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` to lower than `500ms` is **not** recommended as it may cause degraded changefeed performance. [#164892][#164892]
+- Lowered the default value of the `changefeed.max_retry_backoff` cluster setting from `10m` to `30s` to reduce changefeed lag during rolling restarts. [#164936][#164936]
+- Fixed a rare race condition where `SHOW CREATE TABLE` could fail with a `"relation does not exist"` error if a table referenced by a foreign key was being concurrently dropped. [#165274][#165274]
+- 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. [#165562][#165562]
+- 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. [#165994][#165994]
+- Fixed a bug where restoring a database backup containing default privileges that referenced non-existent users would leave dangling user references in the restored database descriptor. [#166226][#166226]
+
+<h3 id="v26-1-2-build-changes">Build changes</h3>
+
+- Replaces bors with Trunk merge queue for better performance and reliability. Configuration-only change with no runtime impact - maintains same safety checks while improving CI workflow. [#166814][#166814]
