Release Notes

DirtyHairy/async-mutex (async-mutex)

### [`v0.4.1`](https://togithub.com/DirtyHairy/async-mutex/blob/HEAD/CHANGELOG.md#041) [Compare Source](https://togithub.com/DirtyHairy/async-mutex/compare/v0.4.0...v0.4.1) - Expand documentation and fix a few errors. - Clear timeout after acquiring a lock in `withTimeout`. - Thanks to AkatQuas and aryzing for their contributions. - Update dependencies. ### [`v0.4.0`](https://togithub.com/DirtyHairy/async-mutex/blob/HEAD/CHANGELOG.md#040) [Compare Source](https://togithub.com/DirtyHairy/async-mutex/compare/v0.3.2...v0.4.0) This is a full rewrite of the core implementation. - Allow negative values for semaphores. - Allow weights for `semaphore.acquire` and `semaphore.runExclusive`. A waiter will be dispatched once the value of the semaphore is greater or equal to its weight. - Add `semaphore.getValue` and `semaphore.setValue`. - Allow weights for `semaphore.waitForUnlock`. The promise will only resolve once the value of the semaphore is greater or equal to its weight. - Only resolve `waitForUnlock` once no waiters remain (fixes [#52](https://togithub.com/DirtyHairy/async-mutex/issues/52)). - `waitForUnlock` times out if the `withTimeout` decorator is used.
