If you guys love feature-packed Minecraft releases, you ain't gonna find it here. This release could be considered as a test for Mojang's new bug tracker because every single bug is from tickets on the tracker. The bug fixes include the Tab key not working on Mac, flying squids, slimes on water, texture fixes, chicken's head movements are inverted, and many more. Also a new music disc has been included. See the source link for all the bugs, and start waiting for 1.5 ;)Source: Mojira Bug Tracker
