Spring Boot 1.4.5 includes 50 fixes and a selection of improvements and dependency upgrades. The second (first, really!) maintenance release of the 1.5 line contains over 60 fixes, improvements and 3rd party dependency updates. Thanks to all that have contributed!
The team is now working full speed on Spring Boot 2: a first milestone, including the first release candidate of Spring Framework 5, is expected early April. There are quite a lot of reactive-related features already in 2.0 snapshots. If you’d like to try them out, and we’d love to hear your feedback if you do, please go to start.spring.io and look for the Reactive starters.
