This release changes how the language domains settings are structured in the $conf array within your settings.php file.
If you are updating from version 7.x-1.1 then you will need to make changes to your settings.php file so that your language_domains settings are structured in the following way:
$conf['language_domains']['en'] = 'inenglish.local';
$conf['language_domains']['fr'] = 'enfrancais.local';
I recommend adding the new settings without removing the old before you actually perform the update. The additional settings won't affect the earlier version and the old settings won't affect the newer version. Once you're confident 7.x-1.2 is working for you, remove the old settings.
