Can you provide more detail on which versions don't work out and what exact errors you're getting?

Any version which does not contain Amanieu/parking_lot@cbab7b0. The error is that you try to invoke a non-const function in const context.

This update is fine, one concern

@ErichDonGubler just double checking we're good to force ff on parking_lot 0.12?

[ErichDonGubler]

Pretty sure we should be good; parking_lot_core's latest version is 0.9.9, which uses windows-targets 0.52, which Firefox has a fake force-upgrade crate for (see build/rust/windows-targets/Cargo.toml:3). CC @jimblandy and @teoxoy for 👀.

_{If it doesn't work, I'll be learning a lot as I effect a reversion! 🤪}

(apologies for the noise earlier, should have read this more properly!)
