v0.7.0

• Feature / BC break: Add BufferInfo and Message to represent complex data types,
  represent all map structures as stdClass objects instead of assoc arrays,
  represent message timestamps as DateTime objects and
  change IrcUsersAndChannels structure to its logic represenation.
  (#41, #43, #44, #46, #47 and #49 by @clue)

  Incoming buffers/channels and chat messages use complex data models,
  so they are represented by BufferInfo and Message respectively.

  All other data types use plain structured data, so you can access its structure very similar to a JSON-like data structure.
  All map structures are now represented as stdClass object instead of assoc arrays.
  This only applies to object maps and lists will continue to be represented as arrays.
  This allows for a clear distinction between these concepts and allows you to
  differentiate between empty objects and empty lists.
  This is in line with how PHP's json_decode() function works by default.

  This is a major BC break because this means these data structures can no longer be accessed like normal PHP arrays.
  However, using the new BufferInfo and Message models makes accessing these somewhat easier.
  See the updated examples for more details on practical effect, for example:

  // old
  assert(is_array($message));
  echo $message['sender'] . ': ' . $message['content'] . PHP_EOL;
  assert(is_int($message['timestamp']));
  echo 'Date: ' . date('Y-m-d', $message['timestamp']) . PHP_EOL;
  assert(is_array($message['bufferInfo']));
  echo 'Channel: ' . $message['bufferInfo']['name'] . PHP_EOL;
  
  // new
  assert($message instanceof Message);
  echo $message->sender . ': ' . $message->contents . PHP_EOL;
  assert($message->timestamp instanceof DateTime);
  echo 'Date: ' . $message->timestamp->format('Y-m-d') . PHP_EOL;
  assert($message->bufferInfo instanceof BufferInfo);
  echo 'Channel: ' . $message->bufferInfo->name . PHP_EOL;

• Feature / BC break: Update writeBufferRequestBacklog() parameters and add new writeBufferRequestBacklogAll().
  (#42 by @clue)

  // old
  $client->writeBufferRequestBacklog($bufferId, 100);
  
  // new
  $client->writeBufferRequestBacklog($bufferId, -1, -1, 100, 0);
  $client->writeBufferRequestBacklogAll(-1, -1, 100, 0);

• Feature / BC Break: Automatically send heartbeat requests and replies (ping messages).
  This can be controlled with the new ?ping=0 and ?pong=0 parameters.
  (#38 and #39 by @clue)

• Feature: Support passing authentication as part of URL to Quassel core.
  (#36 by @clue)

  $factory->createClient('quassel://user:h%40llo@localhost')->then(
      function (Client $client) {
          // client sucessfully connected and authenticated
          $client->on('data', function ($data) {
              // next message to follow would be "SessionInit"
          });
      }
  );

• Feature: Ignore unsolicited CoreInfo reports (Quassel v0.13+).
  (#45 by @clue)

• Feature: Support permanently removing networks and improve examples to support disconnected networks.
  (#48 and #50 by @clue)

  // new
  $client->writeNetworkRemove($networkId);

• Feature: Update QDataStream dependency to no longer depend on ext-mbstring.
  (#35 by @clue)

• Improve test suite and add .gitattributes to exclude dev files from exports.
  Prepare PHP 8 support, update to PHPUnit 9 and simplify test matrix.
  (#33 by @carusogabriel, #34, #37 and #54 by @clue and #52 and #53 by @SimonFrings)

v0.6.0

• Feature / BC break: Upcast legacy Network sync model to newer datastream protocol variant
  and only support optional quassel:// URI scheme and always use probing
  (#27 and #31 by @clue)

  This means that both the old "legacy" protocol and the newer "datastream"
  protocol now expose message data in the exact same format so that you no
  longer have to worry about protocol inconsistencies.

  Note that this is not a BC break for most consumers, it merely updates
  the "legacy" fallback protocol to behave just like the the "datastream"
  protocol.

• Feature / BC break: Significantly improve performance by updating QDataStream dependency and
  suggest ext-mbstring for character encoding and mark all protocol classes as @internal only
  (#26 by @clue)

  This update significantly improves performance and in particular parsing
  large messages (such as the SessionInit message) is now ~20 to ~100
  times as fast. What previously took seconds now takes mere milliseconds.
  This also makes the previously implicit dependency on ext-mbstring
  entirely optional.
  It is recommended to install this extension to support special characters
  outside of ASCII / ISO8859-1 range.

  Note that this is not a BC break for most consumers, it merely updates
  internal protocol handler classes.

• Feature / Fix: Report error if connection ends while receiving data and
  simplify close logic to remove all event listeners once closed
  (#30 by @clue)

• Feature: Automatically send current timestamp for heartbeat requests by default unless explicit timestamp is given
  (#32 by @clue)

  // new: no parameter sends current timestamp
  $client->writeHeartBeatRequest();

• Feature: Limit incoming packet size to 16 MB to avoid excessive buffers
  (#29 by @clue)

• Update examples and add chatbot examples
  (#28 by @clue)

v0.5.0

• Feature / BC break: Replace legacy SocketClient with new Socket component and
  improve forward compatibility with new components
  (#25 by @clue)

  Note that this is not a BC break for most consumers, it merely updates
  internal references and the optional parameter passed to the Factory.

  // old from SocketClient component
  $dnsFactory = new React\Dns\Resolver\Factory();
  $resolver = $dnsFactory->create('8.8.8.8', $loop);
  $connector = new React\SocketClient\Connector($loop, $resolver);
  $factory = new Factory($loop, $connector);
  
  // new from Socket component
  $connector = new React\Socket\Connector($loop, array(
      'dns' => '8.8.8.8'
  ));
  $factory = new Factory($loop, $connector);

• Forward compatibility with PHP 7.1 and PHPUnit v5
  (#24 by @clue)

• Improve test suite by locking Travis distro so new defaults will not break the build
  (#23 by @clue)

v0.4.0

• Feature / BC break: The Client implement DuplexStreamInterface and behaves like a normal stream
  (#21, #22 by @clue)

// old (custom "message" event)
$client->on('message', $callback);

// new (default "data" event)
$client->on('data', $callback);

// old (applies to app send*() methods
$client->sendClientInit(…);

// new (now uses write*() prefix)
$client->writeClientInit(…);

// shared interfaces allow for interoperability with other components
$client->pipe($logger);

// allows advanced / custom messages through writable interface
$client->write(array(…));

// supports and reports back pressure to avoid buffer overflows
$more = $client->write*(…);
$client->pause();
$client->resume();

• Feature: Use default time zone and support sub-second accuracy for heartbeats
  (#20 by @clue)

v0.3.1

• Feature: Support SocketClient v0.5 (while keeping BC)

  (#13, #15)
