This is the second and probably the final release candidate for zio-kafka 3.0.0! 🥳
We expect this to be the final release before releasing 3.0.0. Please try it, your feedback is essential! Please find us on Discord, or create an issue on GitHub.
Zio-kafka 3.0.0 brings new features:
- a much easier to use transactional producer
- producer diagnostics
- producer metrics
- graceful shutdown of a stream (experimental)
Zio-kafka 3.0.0 also brings a number of backwards incompatible changes:
- Removal of all deprecated methods, including accessor methods
- Kafka 4.x
- The new transactional producer
- Diagnostics set via consumer settings
restartStreamOnRebalancingmode is no longer supported
Please also see the migration guide. In short: you should always first migrate to zio-kafka 2.12.0 and solve all deprecation issues.
