Now that Magento 2.3 is on the horizon we are preparing our platform for PHP 7.2. In Magento 2.3 support for PHP 7.0 will be dropped and support for 7.2 will be added. As described in our changelog for PHP 7.1, upgrading to PHP 7.2 will be a bit more involved than upgrading to the previous version. Magento heavily relied on mcrypt for encryption which has now been replaced by ext/sodium.
In the coming week(s) we will be gradually preparing our platform to support PHP 7.2 and all required extensions. We compile PHP and all related modules from scratch so that we can perform some optimizations and have more flexibility with regards to the packaging and compile time configurations than what we would get from using the standard OS versions.
Currently we have already shipped a version of the hypernode-vagrant with the core PHP packages installed. This is not enough for running Magento (because essential external modules are still missing), but if you already want to poke around and see what is new in a local development environment that is already possible.
