+### Fixed
+
+- amqp1: Fixed data race in randomString by replacing non-goroutine-safe package-level rand with thread-safe top-level rand.Intn. ([@mmatczuk](https://github.com/mmatczuk), [#4260](https://github.com/redpanda-data/connect/pull/4260))

+- postgresql: Fixed handling of tsvector type in PostgreSQL replication decoder to return raw PostgreSQL text representation. ([@mmatczuk](https://github.com/mmatczuk), [#4261](https://github.com/redpanda-data/connect/pull/4261))

+- oracledb_cdc: Switched from buffering all redo events to streaming them through a callback to reduce memory allocation. ([@josephwoodward](https://github.com/josephwoodward), [#4243](https://github.com/redpanda-data/connect/pull/4243))
+- mysql_cdc: write checkpoint after snapshot ([@josephwoodward](https://github.com/josephwoodward), [#4269](https://github.com/redpanda-data/connect/pull/4269))
