zio/zio-kafka v3.0.0

on GitHub

A brand new major release for zio-kafka: 3.0.0! 🥳

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)
• improved documentation

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
• Consumer diagnostics set via consumer settings
• restartStreamOnRebalancing mode is no longer supported

See the migration guide. In short: you should always first migrate to zio-kafka 2.12.0 and solve all deprecation issues.
