As you know, PHP versions change regularly.
The PHP70 version became depreciated in December 2018, the PHP71 will be depreciated in December.
Changes between versions are minor, but generally provide a gain of between 5 and 15%. We recommend testing directly PHP72 and PHP73 versions, check the compatibility immediately after your test to avoid any surprises.
For new accounts, we will put PHP72 or PHP 73 by default soon.
