Full Changelog: v5.0.7...v5.0.8

Version 5.0.7

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).
