Lettuce 7.0.0.BETA1

The Lettuce team is pleased to announce the first beta release of Lettuce 7.0!

The release focuses on introducing hitless upgrades functionality, API improvements, and cleanup of deprecated features.

Key changes

• Hitless upgrades support for graceful maintenance event handling
• Enhanced JSON API with String-based access to avoid unnecessary conversions
• Removal of deprecated APIs and options as part of the major version upgrade

Lettuce 7.0.0.BETA1 supports Redis 2.6+ up to Redis 8.x and requires Java 8 or newer. The driver is tested against Redis 8.2, 8.0, 7.4, and 7.2.

We encourage you to try out this beta and provide feedback ahead of the general availability release.
