Kallithea 0.6.0 released

[Thomas De Schampheleire]

Hello everyone,

We are very happy to announce Kallithea 0.6.0.
This is a major release, with as most important change the upgrade to Python 3.

We consider this release ready for production use, even
though it isn't feature complete yet and we would like to make more changes
before calling it "1.0".

This also marks the end of the 0.5.x set of releases: any new bug fixes or
security fixes will no longer be applied to 0.5.x but only to 0.6.x. We
encourage everyone to upgrade to 0.6.0 so they are on a supported track.

The full release notes, including upgrade notes, are available at:
https://kallithea-scm.org/news/release-0.6.0.html

We would like to thank everyone that contributed to the Kallithea repository
(directly or by updating translations in Weblate) since release 0.5.2 (the
numbers are the amount of commits)...
