It is my pleasure to announce that a feature-complete Spring Data 2026.0 release candidate is available now! This release is in preparation for the Spring Boot 4.1 release candidate next week. We expect final releases for general availability in May.

This RC ships a couple of New and Noteworthy changes:

• Upsert functionality for Spring Data Relational using MERGE or INSERT … ON CONFLICT … DO UPDATE syntax available on the Template API
• A RedisMessageSendingTemplate complementing annotation-driven Redis Pub/Sub listeners with a consistent usage of the same underlying MessageConverters.
• RedisCache.resetCaches() optimization allowing to reset multiple caches in a single call through FLUSHDB if Redis is used exclusively for caching.

You can find the consolidated list of changes at the release notes for the 2026.0 release train.
