Minimum required PHP version is now 7.1.0. Remember when we started warning you that PHP 5.x support would be going away soon for the last year? Yup, the time has come. This version of Akeeba Backup and Akeeba Solo required PHP 7.1.0 or later.
Remove multiple, unnecessary copies of the cacert.pem file. It appears that we were accidentally shipping multiple copies of the fairly big cacert.pem file which contains the root TLS certificates used to validate HTTP communications. We only really ever needed one copy. This has been now fixed.
Miscellaneous bug fixes. We regularly address issues in our software. Pelase check the changelog below.
We only officially support using our software with PHP 7.1, 7.2, 7.3 or 7.4.
While our software still runs on PHP 7.1 we are no longer testing our software with this PHP version or consider it an actively supported environment for our software.
We strongly advise you to run either of the two latest available version branches of PHP on a branch currently maintained by the PHP project for security and performance reasons. Older versions of PHP have known major security issues which are being actively exploited to hack sites and they have stopped receiving security updates, leaving you exposed to these issues. Moreover, they are slower, therefore consuming more server resources to perform the same tasks.
Kindly note that our policy is to officially support only the PHP versions which are not yet End Of Life per the official PHP project with a voluntarily extension of support for 6 to 9 months after they become End of Life. After that time we stop providing any support for these obsolete versions of PHP without any further notice. New version branches of PHP will be supported experimentally starting sometime during their Release Candidate phase and fully about 4 to 8 weeks after the first stable version of that branch is released.
We officially only support the latest WordPress 5.x release.
Our software should also work on WordPress 4.9 and ClassicPress 1.x since we do not rely on any features added in later WordPress versions. However, we no longer test against these versions of WordPress / ClassicPress and do not consider them supported environments for our software.
We fully support single site and multi-site installations of WordPress. Multi-site installations can be converted on restoration from directory-based to subdomain-based or vice versa. You cannot restore a single site backup into a multi-site installation. You cannot restore / convert a blog of a multi-site network installation into a single site WordPress installation (in fact, there is no official WordPress method to do that safely).
Using our software with versions of WordPress earlier than 4.9 may be possible but we cannot provide any support for them. Furthermore, we very strongly discourage using our software with WordPress versions earlier than 4.6 because some WordPress features we rely on for our software to function properly did not exist in these very old, End of Life versions. We generally strongly advise against running old, no longer maintained versions of WordPress for security and performance reasons.
We are actively supporting Joomla 3.9 and 4.0. Joomla 4 support is considered experimental since it is still in beta.
Akeeba Solo should be able to back up and restore sites running on Joomla 1.5 or later. However, some of the restoration features in the Site Setup page may have no effect on sites older than Joomla 3.6. We recommend against using obsolete versions of Joomla. We do not test against them anymore and they include known security vulnerabilities which make them unsuitable for use on production sites.
