Tracktable 1.2.3 is released. This is a bugfix release. There was a bug that prevented tracktable.geomath.compute_bounding_box() from working on trajectories that had been restored from pickle files. Other (mainly cosmetic) bug fixes are listed in the release notes.
Source code and binary install packages are on the Downloads page as usual. If you’ve installed Tracktable via pip you can upgrade with pip install --upgrade tracktable.
