Changelog

Sourced from async-lock's changelog.

Version 3.0.0

• Breaking: Add an enabled-by-default std feature that allows using this crate without the standard library. (#43)
• Support blocking and non-blocking operations on the same locks. (#56)
• Switch to a more efficient event notification mechanism. (#43)

Version 2.8.0

• Fix a bug where the SemaphoreGuard::acquire_arc future would busy wait under certain conditions (#42).
• Add a Semaphore::add_permits() function to increase the number of available permits on the semaphore (#44).
• Make RwLockReadGuard covariant over its lifetime (#45)
• Add RwLockReadGuardArc, RwLockWriteGuardArc, and other reference counted guards for the RwLock type (#47).
• Loosen the Send/Sync bounds on certain future types (#48).
• Fix UB caused by the MutexGuardArc::source function allowing the user to drop an object in a different thread than the one it was acquired in (#50). This is a breaking change, but in the name of soundness. Therefore it doesn't break any valid behavior.

• Support wasm64.

Version 2.5.0

• Fix an issue where the future returned by Mutex::lock_arc/Semaphore::acquire_arc holds a reference to self. (#20, #21)

Version 2.4.0

• Add WASM support. (#14)

Version 2.3.0

• Merge all subcrates.

Version 2.2.0

• Add functions to upgrade and downgrade RwLock guards.

This is the reported breaking change for this version FWIW:

Breaking: Add an enabled-by-default std feature that allows using this crate without the standard library. (#43)

[mockersf]

should maybe be updated with async-fs

[mnmaita]

I've done that here.

Closing in favor of #10370.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
