UPGRADE FROM 2.1 to 2.2

HttpFoundation

  • The MongoDbSessionHandler default field names and timestamp type have changed.

    The sess_ prefix was removed from default field names. The session ID is now stored in the _id field by default. The session date is now stored as a MongoDate instead of MongoTimestamp, which also makes it possible to use TTL collections in MongoDB 2.2+ instead of relying on the gc() method.

  • The Stopwatch functionality was moved from HttpKernel\Debug to its own component

Deprecations

  • The Request::splitHttpAcceptHeader() is deprecated and will be removed in 2.3.

    You should now use the AcceptHeader class which give you fluent methods to parse request accept-* headers. Some examples:

    $accept = AcceptHeader::fromString($request->headers->get('Accept'));
if ($accept->has('text/html') {
    $item = $accept->get('html');
    $charset = $item->getAttribute('charset', 'utf-8');
    $quality = $item->getQuality();
}

// accepts items are sorted by descending quality
$accepts = AcceptHeader::fromString($request->headers->get('Accept'))->all();

Form

  • The PasswordType is now not trimmed by default.
