Following the existing planning, Mageia 4 Beta 1 should be released on 2013/10/31.
It looks like witches and pumpkins are playing a part in this release. Due to a nasty bug discovered on rpm itself, we have made an early decision to reschedule the release. It will allow some time to fix this bug properly and test the fix.
The planned new release date will now be 2013/11/06.
