ROOT I/O in pure Python and NumPy.
@NiclasEich fixed a significant performance bug in jagged array writing.
I cleaned up many of the NumPy 1.20 warnings.
Remove warning on import (issue #533).
Switch from DeprecationWarning to FutureWarning.
Rename uproot-methods → uproot3-methods, since the fact that "uproot-methods" as a package with different versions was breaking dependencies for people with old versions of this package.
First version to be named uproot3, rather than uproot.
@eduardo-rodrigues and @chrisburr updated tests for Python 3.9. Thanks!
Added a deprecation warning that points to scikit-hep/uproot4.
Can finally read unsplit TTrees like small-evnt-tree-nosplit.root and added ROOT 6.20/04 tests.
Fixed #485 with PR #486.
