as you know we only get a 'public version' sam keeps fixes for his private one, however, he will allow upgrade/fixes via a public repository, people can submit fixes & pending sams approval they will be added to public repository, & will be available as updates for public version. afaik this hasn't happened yet, but there was a version of e2iplayer released lat week that allowed you add a new update source for public repo, nothing to update as yet.
