Music21's development continues with v.9.3, the first release since Myke Cuthbert's year-long sabbatical and first since June 2023. Thanks to the community for great patience, new developments, new docs, new contributions, and extreme resilience during a summer 2024 spam attack (the first time I took 4 days off out of cell-phone range, they struck!) and doc/homepage problems as the project changed homes.
Music21 v.9.3 is the first release version to officially support both Python 3.12 and Python 3.13. It will probably also be the last to support Python 3.10 and the last to have primary compatibility for numpy v1 and matplotlib v2. The next version will move to the latest major versions of those libraries (if all goes well!) and work to take advantage of their new ecosystems. (However, there are some good PRs waiting to be merged, so there may be one more release before breaking compatibility)
It is designed to be mainly backwards compatible with v9.1 (the first v9 release) but there are a few little things that fix common errors that are not strictly backwards compatible.
This is a minor release with no major new features or changes, mostly bug-fixes, new compatibilities, fixed docs, etc. I want to single out @TimFelixBeyer for contributing a number of optimizations and speed ups, along with many new and long-time contributors (new contributors listed below).
New Home: Old Gratitude
This is the first version of music21 released since I left being a prof at MIT (my wife has been a professor of music at University of Hawai'i since just before the pandemic and the commute to Boston was too long; she supported my career for a decade and I'm proud to be able to do the same for her). I want to thank my colleagues, staff, students, and donors at MIT who helped music21 through its first nine versions. I'm still in the process of "unpacking the boxes" at https://www.music21.org/music21docs/ but things will go well. And thanking my co-founders and fellow music theory nerds at https://www.artusimusic.com/ for knowing the value of music21 as part of our ecosystem there.
