[[release-2.5.0-beta1]]
== *Release 2.5.0.Beta1* _(December 4th 2023)_

See the https://issues.redhat.com/secure/ReleaseNote.jspa?projectId=12317320&version=12416250[complete list of issues].

=== Kafka compatibility

This release has been built against Kafka Connect 3.6.0 and has been tested with version 3.6.0 of the Kafka brokers.
See the https://kafka.apache.org/documentation/#upgrade[Kafka documentation] for compatibility with other versions of Kafka brokers.


=== Upgrading

Before upgrading any connector, be sure to check the backward-incompatible changes that have been made since the release you were using.

When you decide to upgrade one of these connectors to 2.5.0.Beta1 from any earlier versions,
first check the migration notes for the version you're using.
Gracefully stop the running connector, remove the old plugin files, install the 2.5.0.Beta1 plugin files, and restart the connector using the same configuration.
Upon restart, the 2.5.0.Beta1 connectors will continue where the previous connector left off.
As one might expect, all change events previously written to Kafka by the old connector will not be modified.

If you are using our container images, then please do not forget to pull them fresh from https://quay.io/organization/debezium[Quay.io].


=== Breaking changes

MongoDB no longer allows doing collection snapshot on a specific shard in sharded deployment.
This was never intended and supported feature and was removed as a step in complete replica set streaming mode removal (https://issues.redhat.com/browse/DBZ-7139[DBZ-7139]).

`ComputePartition` SMT was deprecated and replaced with significantly improved `PartitionRouting` SMT.
The original SMT is now completely removed (https://issues.redhat.com/browse/DBZ-7141[DBZ-7141]).

JDBC Sink connector was storing default values in database columns when `null` value was streamed and such value existed.
This was incorrect behaviour and is now fixed (https://issues.redhat.com/browse/DBZ-7191[DBZ-7191]).
