Today the Banshee development team released Banshee 1.5.3. 
The immediate release of Banshee 1.5.3 brings lots of new features, with loads of fixes (75) since 1.5.2. Here’s a list of many of the new features (from banshee-project.org
Sync Device From Playlist Option
Either manually manage what files are added/removed to your device, or choose a playlist to sync from. You can make a size-limited smart playlist to sync just the right amount to your device.
Type-ahead Find in Track, Artist, and Album Lists
An alternative to filtering, type-ahead find jumps you to the first track to match your query. Activate with shift+/, cancel with Esc, and jump to next match with F3. In track list it matches against artist, album, or title.
Optional Cover Art in Lower-left Corner
Turn on via View > Show Cover Art
Cover Art Editable via Drag-and-Drop and Right-click
Can edit via the cover art in the track editor, lower-left corner, and beside the seek-slider.

Audiobooks Library
Rough first version, main benefits are separating your books from your music and defining a different file system organization. In future versions we plan to add intuitive bookmarking and a better browsing experience. Enable in Extensions tab of Preferences.
Library-folder Watcher
Watches your libraries’ folders for added, renamed, or deleted files, and updates your libraries appropriately. Requires Mono >= 2.4.3. Enable in Extensions tab of Preferences.
eMusic Importer/Downloader
If you have purchased music from eMusic and have a .emx file, Banshee will download and import the music files for you. Select ‘eMusic Files’ from the normal Media > Import Media dialog. Enable in Extensions tab of Preferences.
GIO File Backend, Supports Non-local Files
This backend uses the GIO library to support importing local files and network-share files alike. Requires glib >= 2.22 and Gio#.
As I stated in the title Banshee 1.5.3 also brings the return of Mac OS X Support, which can be seen here:
