NOTE: All communication is subject to the Numba Code of Conduct.

0. Feature Discussion/admin

1. New Issues

• #7069 - Support accessing static values of classes in JIT functions
• #7065 - Cudasim tests will fail when NumPy 1.20 is added to the test matrix
• #7063 - Numba installation scripts exhibit a race condition during parallel builds
• #7062 - Compile time constant overflow
  • Stuff can overflow and the compiler folds constants
  • Perhaps leave some notes on the issue that this may be potentially solvable with overflow checks
  • Pow function is due for a review anyway
• #7060 - prange with randomised / shuffled iteration
• #7059 - CUDA typing / lowering can't find contains_impl for char sequences
• #7055 - Make repr on TypeRef more verbose

Closed Issues

• #7071 - Native installation of Numba using pip on M1 macOS
• #7054 - TypingError: movemen is not defined

2. New PRs

• #7070 - Improve the issue templates and pull request template.
  • Recently made the template much shorter
  • Maybe we don't need this overhead?
  • Most of the user-base are not compiler engineers
  • It is sufficient to hand in a reproducer, just hand in a small code snippet
  • We may want to keep the barrier of entry nice and low
  • Perhaps most of this information can be queried
  • Dumping environments destroys the search facility of issue trackers --> e.g. the Pandas issue tracker when you search for `numba``
  • A few things may be good though:
    • A refernecable issue when a PR is opened (!!!) <-- THIS MUST GO IN.
  • Maybe a short sentence "You did X, you expected Y and Z happened instead".
  • We may need to reject this PR, but since it is well intentioned, we need to be deliberate in our communication
  • The effort should go into the reproducer.py rather than filling out long templates
• #7068 - Enhancing docs about PRNG seeding
• #7067 - Implement np.isclose
• #7066 - Fix #7065: Add expected exception messages for NumPy 1.20 to tests
• #7064 - Testhound/host array performance warning
• #7061 - Add ndarray allocator classmethod
• #7058 - Convert operator module functions to overloads.
• #7057 - Fix #7041: Add charseq registry to CUDA target
• #7056 - Change prange conversion approach to reuse header block.

3. Next Release: Version 0.54.0/0.37.0, RC=June 2021
