It adds a dozen bugfixes to RAP 1.5. We always backport fixes very carefully in order to maintain the stability of the release. Therefore, only critical or very obvious fixes have been included. So if you are running RAP 1.5, you can now safely upgrade to 1.5.1. The service release is included in the Juno repository, zip files can be downloaded from the project’s download page.
Thanks to everyone who reported bugs and helped to improve this release!
