zio/zio-kafka v3.0.0-rc1

on GitHub

This is the first release candidate for zio-kafka 3.0.0! 🥳

We expect this release to be production ready, but just to be sure we created a release candidate to allow everyone to try it out first. 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
• 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
• restartStreamOnRebalancing mode 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.
