https://tools.wmflabs.org/pywikibot/ ships the last stable and the last master release of Pywikibot. Because Python 2 is deprecated and Pywikibot support will be dropped soon there should be a 3rd section for the python 2 branch tagged with "python2". Currently this is the same as "stable" tag but in near future this might be the last release which supports Python 3
There is not any link in tool webpage. But compat files are still on their original urls. Not generated from source every day, only static. This will happen with last python2 release too.
