The 1.3.x line of pytest-testmon brought a lot of functional and compatiblity improvements:

• much smaller .testmondata saving space and improving performance
• doctest and doctest modules support
• support for pytest 7
• --testmon-noselect now sorts the tests! All the tests are executed but the affected go first. Unaffected tests only follow afterwards. Quickest tests are still prioritized within each subgroup.
• compatibility with Python 3.11
