Improved Backup on Update. You can now choose which backup profile to use when Akeeba Backup takes a backup of your site before Joomla! Update performs a Joomla! version update.
Improved compatibility with Magento and other scripts violating MySQL's auto_increment rules. ANGIE can now restore database tables with rows containing a zero value in an auto_increment field. This is used in Magento and Drupal, even though MySQL clearly warns against this practice, citing it as particularly discouraged.
This version requires PHP 5.3, 5.4 or 5.5. The rationale behind this is explained in our statement of mid-February 2013. It won't install on hosts running PHP 5.2 or earlier. PHP 5.3.4 or later is required, due to show-stopper bugs in earlier versions of PHP 5.3. Moreover, due to the necessary Joomla! API changes found only in Joomla! 2.5.6 or later, this version will not install on Joomla! 2.5.5 or earlier versions. In any case, it will tell you exactly why it cannot be installed (minimum PHP or Joomla! version not satisfied).
This version of our software can be installed on Joomla! 2.5.6 or any later 2.5.x release, as well as any 3.2.x or 3.3.x release. It is not compatible with Joomla! 3.0 or 3.1. These versions of Joomla! are old and vulnerable. If you are using them please upgrade to the latest Joomla! 3 release available from Joomla.org.
