Subject Re: What is in a version? (was Towards faster releases)

Hello,

If you include new functionality this means that according to semver you increase the second
digit, which means conservative users will do this upgrade step not so easy anymore  (and
therefore miss all future fixes).

I would rather include enhancements anyway but divert from strict semver: The most visible
change would be that the minimum prerequisites for a plugin needs to observe the last digit
(like it is today). So the meanings of the digits are more risk than compatibility oriented.

Applying stricter semver would require to not ship enhancements until a new functional release
is cut (and then deciding if older functional releases still get bugfixes or not).

Bernd

BTW: I think this is totally Independent of the topic if running Integration builds with automatic
promotions.
