1.0.0 (2018-07-11)

First stable LTS release, now following SemVer. We'd like to emphasize that this component is production ready and battle-tested. We plan to support all long-term support (LTS) releases for at least 24 months, so you have a rock-solid foundation to build on top of.

Contains no other changes, so it's actually fully compatible with the v0.7.7 release.

0.7.7 (2018-01-19)

Improve test suite by fixing forward compatibility with upcoming EventLoop releases, avoid risky tests and add test group to skip integration tests relying on internet connection and apply appropriate test timeouts. (#128, #131 and #132 by @clue)

0.7.6 (2017-12-21)

Fix: Work around reading from unbuffered pipe stream in legacy PHP < 5.4.28 and PHP < 5.5.12 (#126 by @clue)
Improve test suite by simplifying test bootstrapping logic via Composer and test against PHP 7.2 (#127 by @clue and #124 by @carusogabriel)

0.7.5 (2017-11-20)

Fix: Igore excessive fopen() mode flags for WritableResourceStream (#119 by @clue)
Fix: Fix forward compatibility with upcoming EventLoop releases (#121 by @clue)
Restructure examples to ease getting started (#123 by @clue)
Improve test suite by adding forward compatibility with PHPUnit 6 and ignore Mac OS X test failures for now until Travis tests work again (#122 by @gabriel-caruso and #120 by @clue)

0.7.4 (2017-10-11)

Fix: Remove event listeners from CompositeStream once closed and remove undocumented left-over close event argument (#116 by @clue)
Minor documentation improvements: Fix wrong class name in example, fix typos in README and fix forward compatibility with upcoming EventLoop releases in example (#113 by @docteurklein and #114 and #115 by @clue)
Improve test suite by running against Mac OS X on Travis (#112 by @clue)

0.7.3 (2017-08-05)

Readme: Corrected loop initialization in usage example (#109 by @pulyavin)
Travis: Lock linux distribution preventing future builds from breaking (#110 by @clue)

0.7.2 (2017-06-15)

Bug fix: WritableResourceStream: Close the underlying stream when closing the stream. (#107 by @WyriHaximus)

0.7.1 (2017-05-20)

Feature: Add optional $writeChunkSize parameter to limit maximum number of bytes to write at once. (#105 by @clue)
```
$stream = new WritableResourceStream(STDOUT, $loop, null, 8192);
```
Ignore HHVM test failures for now until Travis tests work again (#106 by @clue)

0.7.0 (2017-05-04)

Removed / BC break: Remove deprecated and unneeded functionality (#45, #87, #90, #91 and #93 by @clue)
- Remove deprecated Stream class, use DuplexResourceStream instead (#87 by @clue)
- Remove public $buffer property, use new constructor parameters instead (#91 by @clue)
- Remove public $stream property from all resource streams (#90 by @clue)
- Remove undocumented and now unused ReadableStream and WritableStream (#93 by @clue)
- Remove BufferedSink (#45 by @clue)

Feature / BC break: Simplify ThroughStream by using data callback instead of inheritance. It is now a direct implementation of DuplexStreamInterface. (#88 and #89 by @clue)

$through = new ThroughStream(function ($data) {
    return json_encode($data) . PHP_EOL;
});
$through->on('data', $this->expectCallableOnceWith("[2, true]\n"));

$through->write(array(2, true));

Feature / BC break: The CompositeStream starts closed if either side is already closed and forwards pause to pipe source on first write attempt. (#96 and #103 by @clue)

If either side of the composite stream closes, it will also close the other side. We now also ensure that if either side is already closed during instantiation, it will also close the other side.
BC break: Mark all classes as final and mark internal API as private to discourage inheritance (#95 and #99 by @clue)
Feature / BC break: Only emit error event for fatal errors (#92 by @clue)

The error event was previously also allowed to be emitted for non-fatal errors, but our implementations actually only ever emitted this as a fatal error and then closed the stream.
Feature: Explicitly allow custom events and exclude any semantics (#97 by @clue)
Strict definition for event callback functions (#101 by @clue)
Support legacy PHP 5.3 through PHP 7.1 and HHVM and improve usage documentation (#100 and #102 by @clue)
Actually require all dependencies so this is self-contained and improve forward compatibility with EventLoop v1.0 and v0.5 (#94 and #98 by @clue)

0.6.0 (2017-03-26)

Feature / Fix / BC break: Add DuplexResourceStream and deprecate Stream (#85 by @clue)
```
// old (does still work for BC reasons)
$stream = new Stream($connection, $loop);

// new
$stream = new DuplexResourceStream($connection, $loop);
```
Note that the DuplexResourceStream now rejects read-only or write-only streams, so this may affect BC. If you want a read-only or write-only resource, use ReadableResourceStream or WritableResourceStream instead of DuplexResourceStream.

BC note: This class was previously called Stream. The Stream class still exists for BC reasons and will be removed in future versions of this package.

Feature / BC break: Add WritableResourceStream (previously called Buffer) (#84 by @clue)

// old
$stream = new Buffer(STDOUT, $loop);

// new
$stream = new WritableResourceStream(STDOUT, $loop);

Feature: Add ReadableResourceStream (#83 by @clue)

$stream = new ReadableResourceStream(STDIN, $loop);

Fix / BC Break: Enforce using non-blocking I/O (#46 by @clue)

BC note: This is known to affect process pipes on Windows which do not support non-blocking I/O and could thus block the whole EventLoop previously.
Feature / Fix / BC break: Consistent semantics for DuplexStreamInterface::end() to ensure it SHOULD also end readable side (#86 by @clue)
Fix: Do not use unbuffered reads on pipe streams for legacy PHP < 5.4 (#80 by @clue)

0.5.0 (2017-03-08)

Feature / BC break: Consistent end event semantics (EOF) (#70 by @clue)

The end event will now only be emitted for a successful end, not if the stream closes due to an unrecoverable error event or if you call close() explicitly. If you want to detect when the stream closes (terminates), use the close event instead.
BC break: Remove custom (undocumented) full-drain event from Buffer (#63 and #68 by @clue)

The full-drain event was undocumented and mostly used internally. Relying on this event has attracted some low-quality code in the past, so we've removed this from the public API in order to work out a better solution instead. If you want to detect when the buffer finishes flushing data to the stream, you may want to look into its end() method or the close event instead.
Feature / BC break: Consistent event semantics and documentation, explicitly state when events will be emitted and which arguments they receive. (#73 and #69 by @clue)

The documentation now explicitly defines each event and its arguments. Custom events and event arguments are still supported. Most notably, all defined events only receive inherently required event arguments and no longer transmit the instance they are emitted on for consistency and performance reasons.
```
// old (inconsistent and not supported by all implementations)
$stream->on('data', function ($data, $stream) {
    // process $data
});

// new (consistent throughout the whole ecosystem)
$stream->on('data', function ($data) use ($stream) {
    // process $data
});
```
This mostly adds documentation (and thus some stricter, consistent definitions) for the existing behavior, it does NOT define any major changes otherwise. Most existing code should be compatible with these changes, unless it relied on some undocumented/unintended semantics.
Feature / BC break: Consistent method semantics and documentation (#72 by @clue)

This mostly adds documentation (and thus some stricter, consistent definitions) for the existing behavior, it does NOT define any major changes otherwise. Most existing code should be compatible with these changes, unless it relied on some undocumented/unintended semantics.
Feature: Consistent pipe() semantics for closed and closing streams (#71 from @clue)

The source stream will now always be paused via pause() when the destination stream closes. Also, properly stop piping if the source stream closes and remove all event forwarding.
Improve test suite by adding PHPUnit to require-dev and improving coverage. (#74 and #75 by @clue, #66 by @nawarian)

0.4.6 (2017-01-25)

Feature: The Buffer can now be injected into the Stream (or be used standalone) (#62 by @clue)
Fix: Forward close event only once for CompositeStream and ThroughStream (#60 by @clue)
Fix: Consistent close event behavior for Buffer (#61 by @clue)

0.4.5 (2016-11-13)

Feature: Support setting read buffer size to null (infinite) (#42 by @clue)
Fix: Do not emit full-drain event if Buffer is closed during drain event (#55 by @clue)
Vastly improved performance by factor of 10x to 20x. Raise default buffer sizes to 64 KiB and simplify and improve error handling and unneeded function calls. (#53, #55, #56 by @clue)

0.4.4 (2016-08-22)

Bug fix: Emit error event and close Stream when accessing the underlying stream resource fails with a permanent error. (#52 and #40 by @clue, #25 by @lysenkobv)
Bug fix: Do not emit empty data event if nothing has been read (stream reached EOF) (#39 by @clue)
Bug fix: Ignore empty writes to Buffer (#51 by @clue)
Add benchmarking script to measure throughput in CI (#41 by @clue)
