Hi, I added some comments, can you look at them? Thanks.

This is bad practise, SSL verify is usefull. Right way is fix SSL issue on server. Alternatively you can extends class GitRepository and change constructor in your code base:

class OwnGitRepository extends \Cz\Git\GitRepository
{
  public function __construct($repository) {
    parent::__construct($repository);
    exec('git config --global http.sslVerify false');
  }
}

$lastLine = exec('git status');
$this->end();
return (strpos($lastLine, 'nothing to commit')) === FALSE; // FALSE => changes
return ((strpos($lastLine, 'nothing to commit')) || (strpos($lastLine, 'branch is behind'))) === FALSE;

This is BC break. Method hasChanges() means "has changes to commit" (I will update phpdoc).

What is your use-case? In what case is last line "branch is behind"? Can you give a example? Probably better will be new method, something like your suggested hasRemoteChanges() or isRemoteSynced().

Probably better is getCurrentRevision()? It's consistent with getCurrentBranch().

It's BC break. Why you need git pull output?

$result = $this->run("git fetch $remote", $params);

Use \n instead of <br>.

Maybe hash is better than head.

Is shortHead really needed? It can be obtained from hash.

Values of $limit and $branch must be escaped - use self::processCommand() and maybe add ' 2>&1' (it redirects error output to STDOUT).

I think better is date in format like 2013-08-18T15:34:40+00:00 (--date=iso-strict) or 2013-09-12 09:43:52 +0000 (--date=iso) than default Sun Aug 18 14:49:42 2013 +0000.

$commits = [];
if (!is_numeric($limit)) {
$command = "git log $limit..$branch --oneline";
exec($command,$shorts);

What if exec fails (for example if git is not installed)?
