The PyO3 upgrade is almost here. Only 3 PRs to go. If anybody has time to review, would love to get these landed this week. (And thanks to @happy-kitchen-89482 for reviews thus far!) • https://github.com/pantsbuild/pants/pull/21498 • https://github.com/pantsbuild/pants/pull/21499 (stacked on previous) • https://github.com/pantsbuild/pants/pull/21500 (upgrade to v0.22 and stacked on previous) The big change for everyone to be aware of is that

&PyAny

and similar references to Rust-side Python values are no longer permitted. PyO3 now requires all accesses to go through the

pyo3::Bound

smart pointer instead. So

Py

for references independent of the GIL and

Bound

for GIL-bound references.
