And technically - comment visible under the same link - this still isn't what we would need to address one of the arguments around not storing tool chain capabilities in .config: The version string may not change, but an update may still have brought a new option the compiler understands (or a downgrade may have taken away one). In fact this change is working against the proposed direction of not making .config contents dependent upon tool chain properties. But of course that proposal wasn't adopted yet, so for the time being this still looks to be an improvement. Jan
