Yesterday patch to fix migration between 5.4.4 <-> 5.5.0 broke migration between 5.5.0 <-> 5.5.0. How did it passed my testing is still a mystery (but that I get confused in too many terminals and tested a wrong binary is a posibility). Problem was that at the start at of cpu_load() we check for the valid versions. I forgot to update that version_id == 9 is a valid version. Just fixed it "forever" and used a right test there. While testing this, I found another bug on ide. How this didn't show up sooner is a bigger mistery(*). Problem here was that ide did this checked for version_id == 3 when it meaned version_id > 2 (to be future proof). I send both for this bugzilla. Eduardo, if you want I can create another bugzilla for the ide one, but I think that the problem here was the combination of the two bugs. I tested this time: 5.5.0 -M 5.4.0 -> 5.5.0 -M 5.4.0 pass 5.5.0 -M 5.4.0 -> 5.5.0 -M 5.4.4 pass 5.5.0 -M 5.4.0 -> 5.5.0 -M 5.5.0 pass 5.5.0 -M 5.4.4 -> 5.5.0 -M 5.4.0 fail as expected 5.5.0 -M 5.4.4 -> 5.5.0 -M 5.4.4 pass 5.5.0 -M 5.4.4 -> 5.5.0 -M 5.5.0 pass 5.5.0 -M 5.5.0 -> 5.5.0 -M 5.4.0 fail as expected 5.5.0 -M 5.5.0 -> 5.5.0 -M 5.4.4 fail as expected 5.5.0 -M 5.5.0 -> 5.5.0 -M 5.5.0 pass 5.4.4 -M 5.4.0 -> 5.5.0 -M 5.4.0 pass 5.4.4 -M 5.4.0 -> 5.5.0 -M 5.4.4 pass 5.4.4 -M 5.4.0 -> 5.5.0 -M 5.5.0 pass 5.4.4 -M 5.4.4 -> 5.5.0 -M 5.4.0 fail as expected 5.4.4 -M 5.4.4 -> 5.5.0 -M 5.4.4 pass 5.4.4 -M 5.4.4 -> 5.5.0 -M 5.5.0 pass 5.5.0 -M 5.4.0 -> 5.4.4 -M 5.4.0 pass 5.5.0 -M 5.4.0 -> 5.4.4 -M 5.4.4 pass 5.5.0 -M 5.4.4 -> 5.4.4 -M 5.4.0 fail as expected 5.5.0 -M 5.4.4 -> 5.4.4 -M 5.4.4 pass 5.5.0 -M 5.5.0 -> 5.4.4 -M 5.4.0 fail as expected 5.5.0 -M 5.5.0 -> 5.4.4 -M 5.4.4 fail as expected (And that is without testing 5.4.0 proper)
