I have today taken Cadabra 2.5.x out of experimental mode and made it the default.
This version contains built-in code to handle LaTeX typesetting, making the notebook interface much faster and enabling things like dynamical cell updates (e.g. updating counters) as well as full UTF-8 support for non-English languages (and emojis...). In the process, I have also fixed a number of issues with the notebook, e.g. interrupting calculations.
As a bonus, it is now possible to distribute Cadabra as an AppImage on Linux, which installs on any reasonably modern distribution. Hopefully this will help to reach a larger audience. I have also updated the homebrew package for macOS. Standard .deb packages for Ubuntu 22.04 are available as well.
Any feedback is welcome; please try this one and let me know!
