I released a new version of mythfs with an improvement and a new feature:

• Improved version of the delete function: it turned out that a recording stayed in the database for several seconds after it was deleted through the mythtv native API. Therefore, the program still appeared in the listing even after a refresh. I now keep track of deleted items for the duration of the CACHE_MAX_AGE. This way, programs will not appear anymore after they have been deleted.
• Added support for browsing recording groups thanks to a contribution of an anonymous visitor of the site (Mail me you name and I properly attribute this contribution to you!)

I have to admit that this release has not been tested as thoroughly as I would have liked to, so please send me your complaints and bug reports.

Downloads are available from Sourceforge. Alternatively, add my repository to your Debian or Ubuntu installation.
