+[[release-2.7.0-alpha1]]
+== *Release 2.7.0.Alpha1* _(April 25th 2024)_
+
+See the https://issues.redhat.com/secure/ReleaseNote.jspa?projectId=12317320&version=12425451[complete list of issues].
+
+=== Kafka compatibility
+
+This release has been built against Kafka Connect 3.7.0 and has been tested with version 3.7.0 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 2.7.0.Alpha1 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 2.7.0.Alpha1 plugin files, and restart the connector using the same configuration.
+Upon restart, the 2.7.0.Alpha1 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
+
+JDBC queries could hang indefinitely in case of database error communication.
+A configurable timeout was introduced to prevent the issue (https://issues.redhat.com/browse/DBZ-7616[DBZ-7616]).
+
+SQL Server connector by default processed all transactions available during each data poll.
+This could lead to out of memeory errors for databases with a large traffic.
+The default value was changed to limit the number of transactions to `500` (https://issues.redhat.com/browse/DBZ-7750[DBZ-7750]).
+
