Changelog:

Quote

v1.4.0 Beta 1
- ADD: New IFbMetadbHandleList interface for a list of metadb handles.
- ADD: fb.GetSelections() method.
- CHG: fb.RunContextCommandWithMetadb() now accept IFbMetadbHandleList.
- ADD: Autoplaylist functions: fb.IsAutoPlaylist(), fb.CreateAutoPlaylist() and fb.ShowAutoPlaylistUI().
- FIX: Script crashes with themes API while changing Windows themes.
- ADD: UI improvements.

v1.4.0 Beta 2
- ADD: New preprocessor directive "feature" (Preprocessors.txt).
- ADD: More methods added to IFbMetadbHandleList interface.
- CHG: IContextMenuManager.InitContext() now accept IFbMetadbHandleList.
- FIX: Possible memory leaks and script crashes in fb.RunContextCommandWithMetadb(), introduced in 1.4.0 Beta 1.
- FIX: minor fixes.

could it be possible to add too an interface to retreive the query of an AutoPlaylist ? and (in priority) a way to re-order playlists idx (maybe a SwapPlaylist() function ?

After using Sort() method for metadb list it seems to be empty (or Count doesn't work).

I've just got a crash with WSH 1.4.0 beta 2 (it's at the top of the stack), I sent the crash report over the official channel. My panels are here.

Also, I use notifier to pass an array from my bio panel to artist art panel, and the artist art panel tends to crash randomly albeit rarely (artist art does not load, even though it has been fetched and it crashes when accessing array arr that holds artist art paths). I don't know why, it happens with both 1.4.0 beta 2 and 1.3.7, but I feel the former does it more frequently. If you can check why it does that, it would help a lot.

@ T.P Wang

could you consider please to add a function to get the query of an autoplaylist (i hope it's possible and not too hard to code for you) ? i really need this ...

Thanx by advance
