Core:
* The functions to configure an handle are unified with a variadic
function named valhalla_config_set().
* Some improvements (speed) with the communications between the threads.
* The statistics can be retrieved with the public API.
* Support for global events (only related to the scanner).
* Improvements with the internal lists (faster and configurable depth).
* A group name can be retrieved with the public API.
* The scanner is disabled when no path is specified.
* The pause mechanism is faster with a group (parsers and grabbers) of
threads. It uses an asynchronious call.
* Faster force-stop by using an asynchronious call with all threads.
* The timeout with cURL is now explicitly set to 20 seconds.
* A cURL transfer can be broken on the force-stop.
* Support for MS Windows and Darwin.
Scanner:
* The first scanning can be delayed. Useful when the front-end is still
loading.
Metadata:
* New metadata callback useful to retrieve the metadata with the front-end
as soon as they are available. Note that the use of this callback is not
recommended.
* Support of priorities with the metadata. The default priorities used by
the parsers and the grabbers can be changed with the public API.
* Support for language with the metadata. It depends of the configuration
in the grabbers.
* The filesize is now part of the metadata (technical group).
Database:
* The public functions for selections are reworked. A first function
prepares the statement and a second is used in order to retrieve the next
available row.
* The results with the public functions can be limited to a specific
filetype and language.
* The files entries with the flag 'external' are deleted when they are no
longer reachable.
* The priority and the language can be changed for a specific metadata.
* The databases from libvalhalla-1 are upgraded automatically.
Grabber:
* Support for concurrent grabbers. It can save about 30% of the time with
a music and video collection and more than one grabber.
* No more dependency on libgcrypt. The HMAC-SHA2 signature for Amazon is
computed by libvalhalla.
* New lyric grabber (ChartLyrics).
* A new attribute (used by ChartLyrics) provides the possibility to set a
minimum time to wait between two grabs.
* Drop LyricsFly grabber (unusable; no valid API key).
* The TVDB grabber is able to retrieve the metadata for a specific episode.
Other:
* Manpage for libvalhalla-test.
* Test suite based on libcheck.
* Many various improvements ...
