+
+### Backwards-Incompatible Changes
+
+- The `ALTER TABLE SPLIT AT` syntax has changed to support multiple splits with one command. Existing uses of `ALTER TABLE t SPLIT AT (x, y)` should be changed to `ALTER TABLE t SPLIT AT VALUES (x, y)`. [#14281](https://github.com/cockroachdb/cockroach/pull/14281)
+
+### Installation Changes
+
+- The Homebrew formula has moved; to install CockroachDB with `brew` use `brew install cockroachdb/cockroach/cockroach`
+
+### General Changes
+
+- CockroachDB now uses `jemalloc` version 4.5.0. [#14287](https://github.com/cockroachdb/cockroach/pull/14287)
+
+### SQL Language Changes
+
+- Collated strings are now fully supported and may be stored in columns. [#13609](https://github.com/cockroachdb/cockroach/pull/13609)
+- New function `isnan()` and special syntax `IS NAN` and `IS NOT NAN` can be used to detect floats that are `Not-a-Number`. [#14248](https://github.com/cockroachdb/cockroach/pull/14248)
+- Variance and standard deviation calculations for integers and decimals now use additional precision internally. [#14013](https://github.com/cockroachdb/cockroach/pull/14013)
+- Decimals with precisions greater than 16 now work correctly. [#14304](https://github.com/cockroachdb/cockroach/pull/14304)
+- `CREATE TABLE AS` now works properly with NULL values. [#14247](https://github.com/cockroachdb/cockroach/pull/14247)
+- The `SHOW application_name` statement is now supported. [#14085](https://github.com/cockroachdb/cockroach/pull/14085)
+- CockroachDB now reports its version in two new places so that clients can distinguish CockroachDB from PostgreSQL: in the `crdb_version` variable in the network handshake, and in a new table `crdb_internal.build_info`. [#14145](https://github.com/cockroachdb/cockroach/pull/14145)
+- `ALTER TABLE SPLIT AT` no longer reports an error if the table is already split at the designated point. [#14273](https://github.com/cockroachdb/cockroach/pull/14273)
+- Casts involving OID and `regclass` types now behave more consistently with PostgreSQL. The `oid()` function is now available. [#13965](https://github.com/cockroachdb/cockroach/pull/13965) [#14022](https://github.com/cockroachdb/cockroach/pull/14022) [#14115](https://github.com/cockroachdb/cockroach/pull/14115) [#14260](https://github.com/cockroachdb/cockroach/pull/14260)
+- Placeholder syntax may now be used for OID values. [#14255](https://github.com/cockroachdb/cockroach/pull/14255)
+- Types with modifiers can now be cast to `::regtype`. [#14030](https://github.com/cockroachdb/cockroach/pull/14030)
+
+### Command-Line Interface Changes
+
+- A new command `cockroach gen haproxy` is now available to generate an `haproxy` configuration file that can be used to access the cluster. [#14205](https://github.com/cockroachdb/cockroach/pull/14205)
+- `cockroach start` now supports a `--pid-file` flag, which names a file to which the process ID will be written when the server is ready to handle requests. [#13996](https://github.com/cockroachdb/cockroach/pull/13996)
+- If any environment variables used by `cockroach` are set but cannot be parsed, this is now treated as a fatal error. [#14124](https://github.com/cockroachdb/cockroach/pull/14124)
+
+### Admin UI Changes
+
+- The log view now shows logs for the requested node. [#13947](https://github.com/cockroachdb/cockroach/pull/13947)
+- The custom time range selector now uses UTC to match the graphs. [#14007](https://github.com/cockroachdb/cockroach/pull/14007)
+- The admin UI now uses relative paths for all links and respects cookies, allowing it to be run behind authenticating proxies. [#14039](https://github.com/cockroachdb/cockroach/pull/14039)
+- The guideline displayed when hovering over a graph is now positioned correctly. [#14008](https://github.com/cockroachdb/cockroach/pull/14008)
+
+### Bug Fixes
+
+- `INSERT` statements with `ON CONFLICT DO UPDATE` clauses that do not specify all columns no longer insert incorrect results. [#14034](https://github.com/cockroachdb/cockroach/pull/14034)
+- `UPSERT` statements no longer incorrectly produce the error "cannot affect row a second time". [#10478](https://github.com/cockroachdb/cockroach/pull/10478)
+- The replica allocator now explicitly recognizes when a node's health is unknown, and avoids situations in which a range could become critically under-replicated. [#14206](https://github.com/cockroachdb/cockroach/pull/14206)
+- Fixed a problem with transaction conflicts immediately after a split that could cause 100% CPU usage. [#14305](https://github.com/cockroachdb/cockroach/pull/14305)
+- The rebalancing system is better able to move replicas to match requested constraints. [#13973](https://github.com/cockroachdb/cockroach/pull/13973)
+- Fixed a race that could lead to a panic when replicas are being moved frequently. [#14306](https://github.com/cockroachdb/cockroach/pull/14306)
+- `SHOW TABLES` no longer fails while a table is being dropped. [#14278](https://github.com/cockroachdb/cockroach/pull/14278)
+- Fixed a crash in some `EXPLAIN` statements. [#14244](https://github.com/cockroachdb/cockroach/pull/14244)
+- Name resolution no longer fails if non-existent databases are present in the search path. [#14006](https://github.com/cockroachdb/cockroach/pull/14006)
+- Logging of "node joined the cluster" events for the UI is more reliable. [#14179](https://github.com/cockroachdb/cockroach/pull/14179)
+- Memory accounting on macOS now correctly reports memory allocated by C code. [#14287](https://github.com/cockroachdb/cockroach/pull/14287)
+
+### Performance Improvements
+
+- Range leases are now transferred to the replica closest to the source of load, when possible. This improves performance in geographically-distributed clusters. [#14268](https://github.com/cockroachdb/cockroach/pull/14268)
+- The replica allocator will actively attempt to move replicas away from no-longer-valid placements when the zone configuration changes. [#14106](https://github.com/cockroachdb/cockroach/pull/14106)
+- Improved the performance of write-heavy workloads. [#14138](https://github.com/cockroachdb/cockroach/pull/14138)
+- Improved caching of range descriptors. [#14217](https://github.com/cockroachdb/cockroach/pull/14217)
+- Reduced overhead in the command queue. [#13982](https://github.com/cockroachdb/cockroach/pull/13982)
+- CockroachDB now enables TCP keepalives on its sockets, improving responsiveness to clients that have disappeared (or load balancers with short timeouts). [#14063](https://github.com/cockroachdb/cockroach/pull/14063)
+- Index backfill now only reads the columns necessary to perform the backfill. [#14271](https://github.com/cockroachdb/cockroach/pull/14271)
