A notice if you are interested in the YajHFC source code:

The YajHFC source code repositories and the issue tracker have moved to GitHub
The Bitbucket repositories will continue to exist for now, but no longer be updated; in June 2020 they will be deleted by Bitbucket (for details see here).

If you are a just a user of the program and not interested in the source code, this will change nothing for you.
