Yesterday WordPress released version 4.0 or “Benny” of WordPress. I have now downloaded it and packed up for Debian users. The files just hit the ftp-master a few minutes ago and will then be distributed out to the various Debian mirrors.
The upgrade should go smoothly but you will probably need to upgrade the twentytwelve/twentyfourteen themes if you have them installed. It seems release 4.0 they also updated these themes.
My next Debian task for wordpress is to re-examine the permissions and locations of wp-content to see if we can have something that permits online updates of the plugins and themes but is still FHS compliant. I’ve also had some people report they have some installation problems, mainly around configuration and directories so let’s see if that can get fixed too.
