Spring Data tracks SLF4J, Kotlin, Jackson, Hibernate upgrades

By RepoJournal · Filed · About Spring

1 person shipped this

Spring Data's build and data modules rolled out a coordinated set of dependency upgrades across SLF4J, Kotlin, Jackson, Project Reactor, H2, and Hibernate.

Spring Data's build pipeline moved forward in lockstep. SLF4J climbs to 2.0.19 [1], Kotlin to 2.4.20 [2], and Jackson 3 to 3.1.6 [3], while the build now targets Project Reactor 2026.0.0-SNAPSHOT [4]. These are routine maintenance bumps, but they signal the compatibility baseline for the upcoming Spring Data release train. If you're building against the unreleased Spring Data snapshots, expect these versions in the next milestone.

The data modules follow with database and ORM updates. Both spring-data-relational and spring-data-jpa move to H2 2.5.250 [5][7], and spring-data-rest plus spring-data-jpa adopt Hibernate 7.4.7.Final [6][8]. The Hibernate bump is the one to watch if you're tracking a Spring Data JPA upgrade path: Hibernate 7.x is the major that changes how mapping and persistence behave compared to 6.x. These are all consistent with the configuration-driven approach Mark Paluch continues, one commit at a time.
