This just in from our friendly Banshee hackers Gabriel Burt and Aaron Bockover (and many others). Banshee is of course our preferred media player at the OPS Americas blog and for good reason!
We have just released Banshee 1.0 Beta 1, aka 0.99.1! This release adds some major features and lots of polish.

MTP and iPod device support have landed! Both MTP and iPod support album artwork, on-the-fly transcoding (converting between file formats), and video support!

Other features and fixes include:

Default Smart Playlists
This release also features default smart playlists, created for new users and users with zero smart playlists. There is a more extensive list of predefined smart playlists, including the defaults, available in the New Smart Playlist dialog.
Thanks to Aaron Bockover, Alexander Hixon, Bertrand Lorentz, Christopher Rogers, Scott Peterson, Sebastian Dröge, and Wouter Bolsterlee for code contributions for this release, and to Daniel Nylander (sv), Gabor Kelemen (hu), Jordi Mas (ca), and Wouter Bolsterlee (nl) for updated translations! And to Jorge Castro for testing and release notes help, and Michael Monreal and Andrew Conkling for testing and bugzilla work!
