 KDevelop 4.2 was ported from SmartRanges to MovingRanges, and Kate 4.4 only has SmartRanges.
 4.5.0 and 4.5.1 are unusable (constant crashes), use 4.5.2 or later. There was a critical bug in the MovingRanges implementation that got fixed in trunk (4.6), but the developer didn't remember to backport it to 4.5. It was only noticed and backported in KDE 4.5.2.
 KDE 4.6 dropped support for the old SmartRanges in favor of MovingRanges. KDevelop 4.0 and 4.1 only support SmartRanges and not MovingRanges.
