Despite the minor version number change, this is a major achievement with more than 500 tasks and issues closed with this release.

Many thanks to the contributors, to our customers and partners, and to our community.

Work is already starting on the next version of the Nuxeo platform (currently numbered 5.4.3, but this may change). We'll announce some of our plans next week, but in the meantime, I'd like you to enjoy the new release, to report any issue you may find of course, and maybe also to discuss your wishes for the next version(s).
