## Discussion

* 0.62.0rc1 / 0.45.0rc1
    * NEWS 
        *  they went out
        *  there were issues
        *  some bugs / regressions
        *  lots of GHA build issues
        *  LLVM 20 included
        *  Two users reported their project was fine: NuCS and STUMPY
        *  this week: cleanup and bug fixing :: next week: rc2 / FINAL (?)
    *  TODO
        * fix stuff in milestones, bugs and GHA (Swapnil & Val)
        * post-release actions from checklists (Val)
        * test on conda-forge (Graham)
        * decide on rc2 vs FINAL
          * not testing new code, no user-testing required
          * needed to test the build infrastructure
          * needed because rc1 showed some issues with the build infrastructure
          * what else can we use? weeklies? weeklies or nightlies may eat up a lot of infrastructure cost.
          * the rc2 was deemed necessary because the linux wheels were missing from PyPi

* https://github.com/numba/llvmlite/issues/1243#issuecomment-3245276156
  * maybe wait for conda-forge?
  * what about NumPy wheels?   

* https://github.com/numba/numba/issues/10130#issuecomment-3233382431

* Note: PyPi stats are back up and Numba is being downloaded about 1 Million times a day.
