Spring Boot 1.0.0.RC2 Released

The second release candidate for Spring Boot 1.0.0 has now been released and published to the Spring Maven Repository.

UPDATE: We have released 1.0.0.RC3 earlier than expected to address an unfortunate regression with RC2. Please use RC3 in preference to RC2.

This release incorporates over 40 improvements and fixes. If you are upgrading from RC1, you may need to change some of your import declarations as we have restructured a few packages with this release.

As well as bug fixes, there are a couple of new noteworthy features:

Migrating from Spring Framework 3.2 to 4.0.1

After this week’s 4.0.1 release, I’d like to take the opportunity to point out our recently revised migration guide on GitHub: That document contains a lot of detailed system requirements etc for your migration to the Spring Framework 4 line. If you haven’t already, now is a great time to give this a try, since the 4.0.1 release contains fixes for all known production-impacting issues that have been reported against the 4.0 GA release.

I’d particularly like to invite all WebSphere users to give the upgrade a try. We carefully designed Spring Framework 4 to be compatible with WebSphere still, and introduced a set of refinements in 4.0.1 towards fine-tuning the Spring experience on WebSphere. Several of those refinements have also been backported to 3.2.7, so in case you aren’t prepared for a 4.x upgrade yet, please upgrade to 3.2.7 first - as a starting point!

Spring Framework 4.0.1 & 3.2.7 released - and 3.1.x retired

Dear Spring community,

It’s my pleasure to announce that Spring Framework 4.0.1 is finally available now, accompanied by a 3.2.7 release. Both releases come with significant bug fixes and improvements over their immediate predecessors and are strongly recommended for an upgrade. Please see JIRA
for details on the issues addressed in each release.

Note that the 3.2.7 release officially turns the Spring Framework 3.2.x line into maintenance mode. A 3.2.8 release is planned for later this year; however, it will only contain bug fixes and is intended to be the last regular 3.2.x release. Further features are now only to be expected in the 4.0.x series as well as 4.1, with the latter scheduled for general availability in August.
