Release v5.0.7
Friday, 14 April, 2023 (tar, zip)
Note: This release introduces a slight change in behavior. Previously, uproot.dask would default to step_size=”100 MB” if open_files=True and whole-file-steps (limit on step size) if open_files=False. Now both open_files cases default to steps_per_file=1 (whole-file-steps) for uniformity. If you have been using uproot.dask and this version suddenly gives you large Dask partitions, use either step_size or steps_per_file to control your partition size (step_size=”100 MB” is the old behavior).

Earlier releases
Uproot versions 1 through 3 were in a different GitHub repository: scikit-hep/uproot3.
PyPI full history (including versions 1 through 3).
This was to allow users to transition from Awkward Array 0.x and Uproot 3.x, which had different interfaces (especially Awkward Array). The transition completed on December 1, 2020.
