Maxima 5.46 came out (https://sourceforge.net/p/maxima/code/ci/master/tree/changel...) in April. It also had a number of bugfixes and some new features, personally I am fond of getting rid of the python dependency for building the documentation, but I suppose preventing gensyms from leaking and fixing limit going into an infinite loop may be considered more important by some.
For Maxima, what could be added?
