### master

- Add new libuv reactor support (`UvReactor`) via the [php-uv extension](https://github.com/chobie/php-uv).
  The php-uv extension must be built [against commit 75fd2ff591](https://github.com/chobie/php-uv/commit/75fd2ff591de2d3571985437de4465dfe8687753) or newer.
- Add `Reactor::watchStream()` alternative for IO watching. The `$flags` bitmask
  paves the way for additional option specs in the forthcoming libuv reactor without
  needlessly complicating the interface.
- Internal watcher IDs now increment from zero instead of PHP_INT_MAX*-1

#### v0.8.1

- Fix bug preventing `NativeReactor` from relinquishing control when no timers or
  stream watchers exist.
- Fix broken `Reactor::at` millisecond resolution.

v0.8.0
------

- Add new `SignalReactor` for capturing and reacting to POSIX signals
- `LibeventReactor` now implements `SignalReactor`
- Remove all concurrency primitives (moved to new After repo)

> **BC BREAKS**:

- Any existing code relying on the Future/Promise/etc concurrency primitives must
  now use the separate After repo as things files are no longer included with Alert.

#### v0.7.1

- `PromiseGroup` now transparently succeeds instead of throwing on empty futures array
- `stream_select()` errors suppressed in `NativeReactor` to silence errors on signal interrupts

v0.7.0
------

- `Future` is now an interface
- Add `Unresolved` as the default pending `Future` (`Promise->getFuture()`)
- Add immutable resolved `Failure` and `Success` futures

v0.6.0
------

- Time intervals are now expected in milliseconds and not seconds.
- Cleaned up unit tests

> **BC BREAKS**:

- Existing interval and delay times must be multiplied x 1000 to retain the same behavior.


v0.5.0
------

- Pare down the Promise/Future APIs
- Minor performance improvements

> **BC BREAKS**:

- Removed `Future::isPending()`
- Removed `Future::failed()`
- Removed `Future::onSuccess()`
- Removed `Future::onFailure()`

v0.4.0
------

- Altered watcher ID generation to avoid potential collisions
- Added optional $onStart callback parameter to Reactor::run() implementations
- Added Scala-like Future\Promise implementation
- Remove `Forkable` things originally added in v0.2.0 (unnecessary)

> **BC BREAKS**: *none*

v0.3.0
------

- Timed event callbacks now passed the reactor instance at param 2 upon invocation
- IO callbacks now passed the reactor instance at param 3 upon invocation
- Minor bugfixes/improvements

> **BC BREAKS**: *none*

v0.2.0
------

- Added `Alert\Forkable` interface for safely forking event reactors without resource corruption
- `Alert\LibeventReactor` now implements `Alert\Forkable`

> **BC BREAKS**: *none*

#### v0.1.2

- Addressed execution time drift in repeating native reactor alarms

#### v0.1.1

- Addressed infinite recursion in repeating callbacks

v0.1.0
------

- Initial tagged release
