First stable release, now following SemVer!

Feature / BC break: Unify SOCKS5 and SOCKS4(a) protocol version handling, the Client now defaults to SOCKS5 instead of SOCKS4a, remove explicit SOCKS4a handling and merge into SOCKS4 protocol handling and URI scheme socks5:// now only acts as an alias for default socks:// scheme. (#74, #81 and #87 by @clue)

// old: defaults to SOCKS4a
$client = new Client('127.0.0.1:1080', $connector);
$client = new Client('socks://127.0.0.1:1080', $connector);

// new: defaults to SOCKS5
$client = new Client('127.0.0.1:1080', $connector);
$client = new Client('socks://127.0.0.1:1080', $connector);

// new: explicitly use legacy SOCKS4(a)
$client = new Client('socks4://127.0.0.1:1080', $connector);

// unchanged: explicitly use SOCKS5
$client = new Client('socks5://127.0.0.1:1080', $connector);

Feature / BC break: Clean up Server interface, add Server::listen() method instead of accepting socket in constructor, replace Server::setAuth() with optional constructor parameter, remove undocumented "connection" event from Server and drop explicit Evenement dependency and mark all classes as final and all internal APIs as @internal (#78, #79, #80 and #84 by @clue)

// old: socket passed to server constructor
$socket = new React\Socket\Server(1080, $loop);
$server = new Clue\React\Socks\Server($loop, $socket);

// old: authentication via setAuthArray()/setAuth() methods
$server = new Clue\React\Socks\Server($loop, $socket);
$server->setAuthArray(array(
    'tom' => 'password',
    'admin' => 'root'
));

// new: socket passed to listen() method
$server = new Clue\React\Socks\Server($loop);
$socket = new React\Socket\Server(1080, $loop);
$server->listen($socket);

// new: authentication passed to server constructor
$server = new Clue\React\Socks\Server($loop, null, array(
    'tom' => 'password',
    'admin' => 'root'
));
$server->listen($socket);

Feature: Improve error reporting for failed connections attempts by always including target URI in exceptions and improve promise cancellation and clean up any garbage references. (#82 and #83 by @clue)

All error messages now always contain a reference to the remote URI to give more details which connection actually failed and the reason for this error. Similarly, any underlying connection issues to the proxy server will now be reported as part of the previous exception.

For most common use cases this means that simply reporting the Exception message should give the most relevant details for any connection issues:

$promise = $proxy->connect('tcp://example.com:80');
$promise->then(function (ConnectionInterface $connection) {
    // …
}, function (Exception $e) {
    echo $e->getMessage();
});

Improve documentation and examples, link to other projects and update project homepage. (#73, #75 and #85 by @clue)
