Lettuce 6.4.0 RELEASE NOTES

The Redis team is delighted to announce general availability of Lettuce 6.4.

This Lettuce driver is now going to be shipped under the MIT licensing scheme. The CLIENT SETINFO is now working in a fire-and-forget mode to allow better compatibility with Redis servers that do not support this command.

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 21.

Thanks to all contributors who made Lettuce 6.4.0 possible.
