. MoinMoin faces a supportability gap in 2020, based on the January 2020 deprecation of Python 2.7. The current release of Moinmoin, 1.9.11, is written in Python 2.7 and is not slated to be ported to Python 3. Moinmoin 2.0, based on Python 3.5, is not yet released (as of Aug. 2019), and "development is very slow going," according to their Python3 support page. Installation of Moinmoin 1.9.11 now yields multiple warnings of this deprecation.

The original MoinMoin "DesktopEdition" is significantly easier to use, because it uses a built-in Web server to display pages, requiring only Python to be installed on the host machine. Since version 1.6.0, the "DesktopEdition" has been integrated into the standard release. Also, in this release a different markup syntax was introduced, which had not been changed much since the early releases.
