PodHawk 1.52 was released today. You can download it as a .zip or a .tar.gz archive here. The archive contains instructions (howtoupdate.txt) on how to update from earlier PodHawk versions.
This is principally a bugfix release. In particular, I have traced and corrected the bug which placed three invisible invalid characters at the beginning of the RSS feed. There is also a new theme (Black Urban) for you to try. You can customise the links at the top of the Black Urban page by simple editing of podhawk/custom/themes/black_urban/index.tpl.
Future plans for PodHawk include Facebook integration, so that your podcasts can be displayed in your Facebook profile, complete with players so that your friends can listen to them; a Flash uploader for file uploading; and a facility for creating and managing playlists. I propose to drop browser file upload (which can only be used for small files) and the CGI uploader; and also support for QuickTime , subject of course to any comments which users may have.
