This release fixes an issue with the Remote JSON API feature used by third party services as well as Akeeba Remote Control CLI and Akeeba UNiTE to take backups automatically. In these cases profile #1 would always be used, despite your preferences.
Good news, folks! We listened to your feedback and restored compatibility with all versions of PHP from 5.3.04 onwards, including 5.4, 5.5, 5.6 and the just-released 7.0. We'd like to remind you that most third party software which can be backed up by our software do not necessarily support PHP 7. As a result we can't guarantee the trouble-free operation of the restoration procedure or the restored site if you are using PHP 7.
Note: there is no such thing as PHP 6. PHP versions jumped from 5.6 to 7.0. Why? Well, it's a long story. TL;DR: It doesn't have to make sense, just accept it.
