Full Changelog: v2.0.0...v2.1.0

Stable release compatible with AMPHP v3 and fibers! 🎉

As with other libraries compatible with AMPHP v3, most cases of parameters or returns of Promise have been replaced with ResolutionType.

Changes from 1.x

• ConcurrentIterator functions have been removed are now available as methods on Pipeline in amphp/pipeline
• FileMutex has been removed, as a better implementation ships as part of amphp/file
• Removed ThreadedMutex and ThreadedSemaphore
• Removed Lock::getId()
• Barrier::await supports cancellation now
• synchronized accepts any Semaphore now instead of a Mutex only
• Added Channel from amphp/parallel, which allows two way communicate between execution contexts, such as two coroutines or two processes. Channel has been modified to extend Closable
• Also added Parcel from amphp/parallel, which allows sharing a value across execution contexts with mutually-exclusive access to modifying that value using Parcel::synchronized().
• Added createChannelPair() function which returns a pair of connected Channel objects.
• Added RateLimitingSemaphore which releases locks after a given time elapses.
• Added StaticKeySemaphore, analogous to StaticKeyMutex

Changes from 2.0.0 Beta 6

• Added RateLimitingSemaphore which releases locks after a given time elapses.
• Added StaticKeySemaphore, analogous to StaticKeyMutex

• Add compatibility with Revolt v1.x

• Fixed return type of createChannelPair() to use the interface
• Fixed close of channels returned from createChannelPair()
• Release locks synchronously instead of asynchronously on explicit release() calls

• PHP 8.1 now required.
• Channel now extends Amp\Closable, which adds an onClose() method to attach a closure that is invoked when the channel closes.

This release moves Channel and Parcel interfaces from amphp/parallel to this library.

• Channel allows two way communicate between execution contexts, such as two coroutines or two processes.
• Parcel allows sharing a value across execution contexts, with mutually-exclusive access to modifying that value using Parcel::synchronized().

• Update to revolt/event-loop v0.2.x (#20)

Note: This is a pre-release, there might be breaking changes in the final stable version.

• Major release avoiding promises in favor of fibers supported by Revolt
• ConcurrentIterator functions have been removed and will be available as operators in amphp/pipeline
• FileMutex has been removed, as a better implementation ships as part of amphp/file
• Removed ThreadedMutex and ThreadedSemaphore
• Removed Lock::getId()
• Barrier::await supports cancellation now
• synchronized accepts any Semaphore now instead of a Mutex only
