I would. With some remarks. I think that having a 5 year cycle for major releases is beneficial. First to users as they know when all the deprecations are being rolled up into behavioural changes and (potential) breakage. But also to us, as maintainers, as it could signal *when* it makes sense to work on deprecations, behaviour changes, and code refactoring (that's more likely to break APIs and extensions). IMO it would make sense to tweak what sort of user land deprecations can be done in the .3 and .4 releases (probably being more strict) compared to the .1-.2 releases. We'd want to enlarge thr time frame for significant changes more ahead of time compared to more minor ones. But I do think we ought to be weary of making these rules, in when to allow to deprecate what, too strict. A rough set of guidelines makes IMO more sense. cheers Derick -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: https://www.php.net/unsub.php
