One of the smaller changes is to add, on the Administration Dashboard, a couple of warnings in case you have a potential problem with the version of PHP you are using. This is important not because kiwitrees might fail if you ignore it (it won’t), but because you might be exposing your valuable family history data to security risks.
The developers of PHP now operate a strict “end of life” policy for each version. They issue specific dates when they will stop providing any maintenance other than security for a version, then another date when even security fixes are stopped.
For example, for 5.3.x versions both standard and security maintenance stopped on 14 August 2014. (You will see a red warning about this in kiwitrees)
Maintenance for 5.4.x stopped on 14 September 2014, and security fixes will end on 14 September 2015.(You will see a green warning about this in kiwitrees until 14 September, when it will become red)
So if you see one of these warnings don’t panic, but do either upgrade your version of PHP, or talk to your web host about it, as soon as possible. You should soon be using at least PHP 5.5, and preferably 5.6.
Kiwitrees has been thoroughly tested on 5.5 and works fine. I want to do more testing on 5.6 but that appears to be OK on sites that are already using it.
