This release addresses an annoying cosmetic bug in Admin Tools Core which would erroneously cause a big yellow banner to prompt you for a Download ID. Admin Tools Core is free of charge and should not ask for a Download ID.
Moreover, this release also solves another issue which would make it impossible to edit multiple items in your Joomla! back-end if the "Set default expiration to 1 hour" option in .htaccess Maker is enabled. users of the Professional release, after the upgrade, please go to Admin Tools, .htaccess Maker and click on "Save and Create .htaccess" to regenerate your .htaccess file.
Finally, the "Remove all instances of Joomla! from the output" feature was removed from the Web Application Firewall. This feature did not offer any substantial protection, as it's possible for a semi-skilled attacker to easily determine within a reasonable degree of accuracy if your site runs Joomla!. Skilled attackers can easily determine the version of Joomla!, usually within 1-3 versions accuracy. However, despite the minimal protection offered by this feature, it would cause a lot of problems on many sites. Therefore we decided to remove it and spare you from the frustration of a pretty much useless feature.
This version is only compatible with Joomla! 1.5 and 2.5. It will not work at all on Joomla! 1.6 and we do not support using it on Joomla! 1.7. Moreover, this is the final release of Admin Tools compatible with Joomla! 1.5. Future releases will be compatible with Joomla! 2.5.x only. Joomla! 1.5 itself will become end-of-life on September 2012. We urge all of our users to upgrade their sites to Joomla! 2.5 as soon as possible.
