Release Notes for Debezium 3.1

All notable changes for Debezium releases are documented in this file. Release numbers follow Semantic Versioning.

Release 3.1.0.Alpha1 (January 20th 2025)

See the complete list of issues.

Kafka compatibility

This release has been built against Kafka Connect 3.9.0 and has been tested with version 3.9.0 of the Kafka brokers. See the 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 3.1.0.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 3.1.0.Alpha1 plugin files, and restart the connector using the same configuration. Upon restart, the 3.1.0.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 Quay.io.

Breaking changes

Source info block schema was not versioned in past Debezium versions. This could lead to schema compatibility issue when changed. The schema version is now set to 1 and will be incremented with future changes (DBZ-8499).

Debeizum intoroduce SparseVector datatype for PostgreSQL sparsevec data. This release introduces support for Oracle vector datatypes and SparseVector was renamed so it became cross-connector type (DBZ-8585).
