Well, nobody are perfect, and a couple of bugs have made it necessary to create a bug fix release of Enonic XP 6.4. The main problem being fixed, is a bug with mismanagement in the deploy folder where old jar-files were not removed when apps or libs were upgraded to newer versions.
All three bugfixes are listed here: https://github.com/enonic/xp/releases/tag/v6.4.2
Enonic XP 6.4.2 may be downloaded from our public repository: http://repo.enonic.com/public/com/enonic/xp/distro/6.4.2/
We hope you will enjoy this release. Please join the discussion below and tell us what you think.
