A word about versioning: Experimental exists for the stable branch and the devel branch.
Those experimental brachnes reflect that both branches need to develop. Not all bleeding edge changes (i.e. experimental changes) to devel are possible to apply on the the 'experimental stable' branch. From time to time those changes are backported to the experimental stable tree. After the changes have proven good, the stable experimental branch may be released as 'stable'. Clear :) ?
