Please note that you need to clear caches after applying this update!
The most important change of this release is that theme-provided library information now actually works. Themes can implement hook_libraries_info() in their template.php just like modules. This supposedly worked in 7.x-2.1 already but did not work correctly.
This is the first stable release in the 7.x-2.x branch.
The following commits have been made since the 7.x-2.0-alpha2 release:
#1606018 by chemical: Tests fail if the module is downloaded from Drupal.org.
#1386250 by tstoeckler: Clarify module and library installation in README.txt.
#1578618 by iamEAP: Fixed Fatal cache flush failure on major version upgrades.
#1449346 by tstoeckler, sun: Clean-up libraries.test
For a detailed list of commits since the 1.0 release, see the release note of the 7.x-2.0-alpha1 and the 7.x-2.0-alpha2 releases.
Most importantly, Libraries API can now manage the library information for you. The idea is that you declare the library information once in hook_libraries_info() and the simply use libraries_load() to load it. Also see the handbook for more information.
This is the first alpha release of the 2.x branch of Libraries API.
You can do a lot more than libraries_get_path() now, see the libraries.api.php file now shipped with the module. A lot is still unfinished and in flux, but if your use-case is not supported by our API yet, we hope to see you in our issue queue!
