Please see the official Bochs Github repository.
This repo was a clone of the official Sourcforge SVN repository [http://svn.code.sf.net/p/bochs/code/trunk]. But the SVN repo has not been updated since 2021, so the GitHub one should be considered official now.
Thanks to /~https://github.com/svn2github/bochs for making the original clone, and providing the svn2github software I could use to keep it going.
