Looks good indeed, but you only address binary compatibility between patch releases. What about minor releases? I suppose there's no binary compatibility for minor releases (ie a plugin written for 3.0 won't work for 3.1), but I prefer to ask just to be clear. > Example: > > The public API of the Qt Creator 3.0 series will be fixed starting from 3.0 > RC, which has internal version > number 2.8.8x, compatVersion 2.8.8x (a).

I'm not sure I'm following you here. Plugins written against 3.0.1 can decide to depend on Core 3.0.1 only. In this case, those plugins won't have a compatVersion of 3.0.0 (like in (c)), but 3.0.1, right? So the dependency really depends on the compatVersion, not the version.
