  • won't have another llvmlite rel by then

• llvmlite PR #979:

  • Consolidate llvmdev and llvmdev_manylinux2014 recipes?
  • There's hardly any difference between them, but how is the manylinux2014 recipe used?
  • Hatchery can be used for building and testing the full stack: https://github.com/numba/numba-hatchery

• Policy item discussion:

  • Issues and similar reported must be done so in plain text in a textbox or via github's gist mechanism (as multiple plain text items in text boxes). No other forms will be accepted.
  • Action item: Update GH templates and docs to reflect this.

• Numba & llvmlite releases

  • in-progress -- few PRs remain, hoping to publish artifacts this week
  • NumPy PRs that are RTM will be included in 0.58

• numba#9132 - Delegate np.zeros to numpy
