The following branches exist:

mde2425 - the branch containing a snapshot of the repo used for the MDE assignments 24-25. No breaking changes will be pushed here. After the re-exams (Sep 2025), this branch will be frozen.
master - currently equivalent to mde2425 (this is the branch that was cloned by the students). This branch will be deleted after Sep 2025, because the name is too vague.
development - in this branch, new development will occur, primarily cleaning up the code to prepare for next year's MDE classes.
