[Benoît Minisini <benoit.minisini@xxxxxxxxxxxxxxxx>]

Hi,

I have just tagged the 3.21.6 version on GitLab.

https://gitlab.com/gambas/gambas/-/archive/3.21.6/gambas-3.21.6.tar.bz2

The changelog is at: https://gambaswiki.org/wiki/doc/release/3.21.6

Please try it to check if everything is ok for you (i.e. you have the 
bug fixes you expected).

Then tell me, and I will make the release official.

Best regards,
