As some of you will know, given some kate recent changes, now it’s not possible to work with KDevelop/KDevPlatform master together with up-to-date kdelibs trunk, so if you want to keep up to date with KDevelop development you will want to freeze your svn trunk to some revision before r1162564.
Another option you have, if you’re a brave KDevelop user is to use the movingranges branch which david’s fixes to work with the new kate ranges system, that will be merged once 4.1 is released.
We understand that it’s a little disturbing for everyone but we hope it’s going to be better really soon :), kdevelop gears don’t stop turning. ^^
