Dear Spring community,
I’m pleased to announce that Spring Framework 5.0.5 and 4.3.15 are available now, as another pair of refinement releases which are recommended as immediate upgrades for all users. Our 5.0.5 release is the foundation for the upcoming Spring Boot 2.0.1 release later this week, and 4.3.15 will be picked up by Boot 1.5.11 around the same time.
Both framework releases come with plenty of bug fixes but also with a wide selection of refinements, wrapping up before we branch towards Spring Framework 5.1 and turn the 5.0.x and 4.3.x lines into low-volume maintenance mode. Our 5.0.5 build is also prepared for running on the recently released JDK 10, allowing the framework to be built and tested on JDK 8 as well as 9 and 10 in the meantime. Last but not least, 5.0.5 (and to a minor degree 4.3.15 as well) includes significant performance improvements for annotation introspection on startup.
2018-04-05 Update: The releases address multiple vulnerability reports. Please see this blog post published after the associated Spring Boot 2.0.1 and 1.5.11 releases.
In terms of the roadmap, we have 5.0.6 and 4.3.16 planned for May before we aim for 5.1 RC1 at the very end of June... preparing for JDK 11 and other infrastructure upgrades. Stay tuned!
