Did a cargo publish --dry-run, yielded this warning:

warning: package `atomic-polyfill v0.1.11` in Cargo.lock is yanked in registry `crates-io`, consider updating to a version that is not yanked

Ah, we don't publish a lock file for rp-hal, so this is all local issues.

LGTM. Compared it with the main branch which didn't show up unexpected differences, so all actual code on this branch has already been reviewed before being merged to main.

CARGO_BUILD_TARGET=x86_64-unknown-linux-gnu cargo semver-checks doesn't complain. That doesn't prove the absence of breaking changes (especially it doesn't detect the change to float_to_fix64 which is formally a breaking change, but it's fine because it's fixing a bug and the code with the old signature was just broken.)

Changelog looks complete and accurate.
