(Unless otherwise noted, from this release onward, all changes described in release notes are for v2.)
ianna added a one-column implementation of `ak.from_rdataframe`: PR 1508.
jpivarski added `ak._v2.types.from_datashape`, though the parser will need work to make it accept all v2 type strings: PR 1513.
1.9.0rc5
jpivarski silenced a known-to-be-fixed NumPy warning: PR 1464.
1.9.0rc4
Changed nothing (relative to 1.9.0rc3) except for the name of the repo: scikit-hep/awkward-1.0 → scikit-hep/awkward. I just want to make sure that all of the test and deployment machinery is still working.
