[Zope-dev] Can ZTK 1.0 support Python 2.7?
Hi. We have Python 2.7 final now and some work has begun on making ZTK packages compatible with it. Currently we still see various test failures in the zopeapp set though and nobody who steps up to fix them. Apart from that, we have made a promise to support Python 2.4 up to 2.6 for the ZTK 1.0 release. The ZODB 3.10 releases do no longer support Python 2.4 but require 2.5. The ZODB 3.9.x releases are in maintenance mode for a while and currently don't support Python 2.7. I doubt that we can get official 2.7 support for the 3.9.x release line. Given all of these, I'm leaning towards not supporting Python 2.7 for a ZTK 1.0 release. A 1.1 can drop Python 2.4 support and we can try to support 2.7 in addition. What do others think about this? Hanno P.S. We talked about a rough timeline for a ZTK 1.0 release in the release team. We are aiming to get a beta out in early August (once we are all back from vacation). Test failures on any of the supported platforms are blocking such a release. This includes any failures we get on Windows. Hopefully more community members will step up and help fix those. ___ Zope-Dev maillist - Zope-Dev@zope.org https://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - https://mail.zope.org/mailman/listinfo/zope-announce https://mail.zope.org/mailman/listinfo/zope )

Actually both Zope2 and Plone 4 (as a potential user of the ZTK) are requiring Python 2.6 and don't even support Python 2.5 anymore.

While I would have thought a syntax change shouldn't mean a major version, breaking compatibility obviously warrants some thought. But then I wouldn't expect a release just based on new syntax.
