Ahoy hoy, I am currently in the progress of landing fairly invasive changes to how documentation is handled in releaseme as previously mentioned in 'cmake magic for documentation' thread after Jonathan was nice enough to get rid of some excess code in the plasma repos that was blocking this.
As a result of this Plasma 5.10.5 needs to be created from the 'Plasma/5.10' branch of releaseme. NOT master! For 5.11 master is good to use again. (reason is that 5.10.5 will still have the code which releaseme supports but kdoctools does not, so releasing 5.10.5 with releaseme from master would change cmake behavior in a point release which is undesirable) HS
