- Rewrites in some older legacy parts of the core (URL routing, template fallback chain, experimental internal caching) as well as PHP7 compatibility.
- New bundled responsive themes "Timeline" and "Clean-Blog"
Improved usability of plugin upgrades by combining sidebar and event plugins and upgrading multiple plugins at once - Permission checks for the dashboard output and comments
- Please see the blog announcement for more info.
Please note that we already got an initial report of a bug in the RC that slipped through: The Upgrade-Button in the plugin-section is not working (you will get the HTTP-Referrer error message, since a token is missing). This is the fix and would need to be manually applied until we can release a patched version (which will be RC-1.1, RC-2 or the stable, depending on whether additionally bugs are found).
