 - Introduced the [cluster setting](../v23.2/cluster-settings.html) `kv.gc.sticky_hint.enabled` that helps expediting [garbage collection](../v23.2/architecture/storage-layer.html#garbage-collection) after range deletions. For example, when a SQL table or index is dropped. `kv.gc.sticky_hint.enabled` is enabled by default in v23.2. The setting has been deprecated in v23.2. [#113040][#113040]
+- Introduced a new [environment variable](../v23.2/set-vars.html) that allows an operator to configure the [compaction](../v23.2/architecture/storage-layer.html#compaction) concurrency. [#113313][#113313]
 - [Debug zip](../v23.2/cockroach-debug-zip.html) will now collect the active traces of all running or reverting traceable jobs. This includes [restores](../v23.2/restore.html), [imports](../v23.2/import.html), [backups](../v23.2/backup.html), and physical cluster replication. [#113172][#113172]

 - Fixed a bug in a method that was used by some of the [jobs](../v23.2/show-jobs.html) observability infrastructure. This method could be triggered if a file was overwritten with a different chunking strategy. [#113290][#113290]
 - Fixed a bug where the result of [`SHOW CREATE TABLE`](../v23.2/show-create.html) for a table that had a [collated string column](../v23.2/collate.html) with a default expression was incorrect because the statement could not be parsed. [#113119][#113119]
 - Fixed the SQL activity update job to: avoid conflicts on update, reduce the amount of data cached to only what the overview page requires, and fix the correctness of the top queries. [#112865][#112865]
+- Fixed a bug that could prevent physical cluster replication from advancing in the face of some range deletion operations. [#113041][#113041]
+- Fixed a bug where [`ALTER TYPE`](../v23.2/alter-type.html) could get stuck if [`DROP TYPE`](../v23.2/drop-type.html) was executed concurrently. [#113644][#113644]
+- Fixed a bug that could cause internal errors or panics while attempting to forecast [statistics](../v23.2/show-statistics.html) on a numeric column. [#113797][#113797]
+- Rolled back deletes no longer cause a discrepancy between computed statistics and the actual stored values. [#113766][#113766]

+- Addressed a performance regression that can happen when the declarative [schema changer](../v23.2/online-schema-changes.html#declarative-schema-changer) is used to create an index with a concurrent workload. [#113725][#113725]
