Every day, a zip is made which contains the sources as they are on this day, they are available from
the FTP site:
http://ftp.freepascal.org/develop.var
This will lead to a download of the sources of the development branch:
https://gitlab.com/freepascal.org/fpc/source/-/archive/main/source-main.zip
https://gitlab.com/freepascal.org/fpc/source/-/archive/main/source-main.tar.gz
and also of the fixes branch:
https://gitlab.com/freepascal.org/fpc/source/-/archive/fixes_3_2/source-fixes_3_2.zip
https://gitlab.com/freepascal.org/fpc/source/-/archive/fixes_3_2/source-fixes_3_2.tar.gz
The creation of the zip files is an automated process, and so these files are created on the
fly.
