Magma is a leading computer algebra system (CAS) for pure mathematics. If you're not familiar with computer algebra, a CAS is just an example of a framework, like Angular or React or Unity; it gives you the tools necessary to do math research so that you don't have to start from scratch. Many computer algebra systems (especially older ones) come with their own programming language, and in this case that language also goes by the name 'Magma'.
Magma has been pretty widely used in Number Theory and Group Theory for many years now. And if you've used Magma and found a past, you might have experienced that it has been... difficult, sometimes, to get bugs fixed.
But there is good news! Times are changing, and now there is this github repo, which serves as an issue tracker for Magma. You can report bugs, request features, or even share permissively-licensed code that you'd like to get incorporated into Magma. Just go to the issue tracker repo and open a github issue; you can look at other issues to get an idea of the format you should use.
I recently spent six weeks in Syndey, Australia working with the Magma group, and I can tell you for certain that the Magma team actively engages with this issue tracker repo, and I can confidently say it is the best way to get your issue addressed.
So from now on, if you find a bug or issue with Magma, don't just accept your fate! Check out the issues and file a new one if yours isn't there!
