Lettuce 6.2.0 RELEASE NOTES

The Lettuce team is delighted to announce general availability of Lettuce 6.2.

This is a massive release thanks to all the community contributions. Most notable changes that ship with this release are:

  • Support for Redis 7.0 commands and modifier/argument updates

Lettuce 6 supports Redis 2.6+ up to Redis 7.x. In terms of Java runtime, Lettuce requires at least Java 8 and works with Java 18.

Thanks to all contributors who made Lettuce 6.2.0 possible.
