At first manual releases (x.y.Z), automate the process to generate the bugfix
releases later. We need to make sure to release only versions sets for which
all tests passed.
ztk x.y.z. releases, stable package list per release
a ztk minor release per month would be ok
a ztk major release “when one of the consumers projects needs it”.
backward compatibility breaking only happens in X.y.z that means, if we have
a zope.component 4.0.0, it will be part of ZTK 2.0 or 3.0
generally upstream releases happen in a 6-12 month interval, so the same
timeline makes sense for ZTK releases
