 - Fixed a bug that could cause a [UDF]({% link v23.2/user-defined-functions.md %}) to return a value that does not conform to the return type of the UDF. This bug was only present for UDFs that return user-defined types. The bug was present since v23.1. [#104151][#104151]
 - Fixed a bug where if a user was logged in while a different session dropped that user, the dropped user would still inherit privileges from the `public` role. Now, CockroachDB checks that the user exists before allowing it to inherit privileges from the `public` role. In addition, any active web sessions are now revoked when a user is dropped. [#104215][#104215]
 - Fixed a bug in upstream `etcd-io/raft` which could result in pulling unlimited amount of logs into memory, and lead to out-of-memory errors. Now the log scan has a limited memory footprint. [#104483][#104483]

 - CockroachDB now automatically deletes statistics for dropped tables from the `system.table_statistics` table. [#105364][#105364]
 - Fixed a rare internal error which occurs when a query uses a "project set" operation involving simple column expressions. [#104756][#104756]
 - The [Raft]({% link v23.2/architecture/replication-layer.md %}#raft) `PreVote` and `CheckQuorum` mechanisms are now fully enabled. These prevent spurious elections when followers already have an active leader, and cause leaders to step down if they don't hear back from a quorum of followers. This improves reliability under partial and asymmetric network partitions, by avoiding spurious elections and preventing unavailability where a partially partitioned node could steal leadership away from an established leaseholder who would then no longer be able to reach the leader and submit writes.
