- Numba 0.61.1 contents
- NumPy 2.2 support
- full fix for coverage reporting bug
- and if there's a fix for the gdb issue, potentially that too?).
- typing fix for #9900
- Resolving https://github.com/numba/numba/issues/9817, the issue is in gdb and has been fixed in the latest release. This means that there's a "window" of broken gdb versions. Discuss what to do...!
- we've done enough work to confirm it is a GDB bug
- https://github.com/numba/numba-scipy/pull/108#issuecomment-2598154179
