Current stable release is 1.4.2… still depending on Python 2.7. https://trac.edgewall.org/wiki/TracDownload#Trac14StableRelease … AFAICT even the 1.5 developing branch is still depending on Python 2.7: https://trac.edgewall.org/wiki/1.5/TracInstall
To install Trac, the following software packages must be installed: Python, version ≥ 2.7 and < 3.0 (note that we dropped the support for Python 2.6 in this release) setuptools, version > 5.6 Jinja2, version ≥ 2.9.3 i see currently no change for Trac.
