Release Notes for for Trac 1.6 Py3 Release

This page documents changes in the 1.5.x releases leading up to 1.6. This page will eventually document the final status of 1.6.

1.5.x releases are "stable" and tested snapshots of trunk​. They can be seen as sub-milestones on the road towards 1.6.

As opposed to maintenance releases, we offer no guarantees on feature and API compatibility from one 1.5.x release to the next.

However, by following 1.5.x you get a chance to use new features earlier, and therefore be able to contribute feedback when things are still in flux. It's also less risky than just getting the latest trunk, as we won't cut a 1.5.x release in the middle of a series of changes, though we had and still intend to have a good record of keeping things always working on trunk.

If you are a plugin developer, also check the ApiChanges/1.6 page.

Highlights

• Dropped support for Python 2.7. Python 3.5+ is supported (#12130).

Code Name

The 0.11 release was dubbed "Genshi", 0.12 "Babel" and 1.4 "Jinja2" after the names of the Python packages that became closely associated to these Trac versions. The most significant change in 1.6 is Python 3 support, so it seems appropriate to name 1.6 "Py3".
