Hi all, here's the second alpha. I hope we got all major regressions fixed for this release that were reported since alpha 1.

Way too much for this announcement. Cython 3.0 comes with a very > long list of new features, bug fixes and modernisations, a few of which are > backwards incompatible, but in a good way.
