    • outstanding 2.11 issue: 965
  • Thoughts on changing the default branch?

    [issue]

    • Jeremy: code doesn’t look dangerous. Josh: agreed, more a question

    • Jeremy: another option would be branching by configuration.

    • Isaac: status page for v3 on what’s being developed would be useful

    • Greg: consensus on file-ending? .zr3?

      • Jeremy: could see some benefit for inspecting paths

        .zr3/path/to/array

  • GSoC 2022

    • Awkward Arrays
    • Isaac: all of AA or ragged arrays / vlen? TBD
    • Dennis: another thing that’s not in the specification
    • https://zarr.readthedocs.io/en/v2.11.1/tutorial.html#ragged-arrays
    • Josh: all agreed. Having a v3 to cover the ragged arrays would be a great outcome
    • Jeremy: only on a chunk? (since a codec)
    • comparison to HDF5
