This release includes a huge number of new features and requires core at least 7.15. Many parts of the module changed since alpha2, hence you should backup your site and test it carefully when upgrading to ensure everything is still working for you.
This features a totally revamped translation UI (see entity_translation.api.php to see if you need to adjust your code. Moreover
hook_translation_info() has gone in favor of plain
hook_entity_info() (see ).
To replicate the behavior of the translation form shipped with alpha2 a new set of (optional) permissions have been introduced, see the related section in the Entity Translation guide.
A new set of options are available to display a language selector on any entity and configure its behavior. These are available in the usual entity translation settings page and have per-bundle granularity.
Another big new feature is native support for menu translation in the node form, more or less what Menu translation (Node) used to provide in D6.
Other major changes include improved integration for the Pathauto and Media modules and the ability to translate alt and title data using the core image field and the Field synchronization feature that can be found on any image field settings.
Many bugs were fixed in the node upgrade code but you should still backup your site before running it as failures are still being reported.
Huge thanks to bforchhammer whose help was crucial to make this release possible.
