Fix mistakes in merging the changelog for this branch.  It occurs to me that when I write 'backported from 3.1.2' it doesn't really make sense because technically the procedure is currently to release the bugfix release for the older branch first.  So when 3.0.11 is released 3.1.2 doesn't technically exist yet :/  Maybe I should change the release order.
