PHP 7.2 will be released on November 30th (the same day as Symfony 4). During the past SymfonyCon Cluj 2017 conference, Sara Golemon, release manager of PHP 7.2, explained that PHP 7.2 is not as revolutionary as PHP 7.0, but it provides a nice 10% performance increase over PHP 7.1 and some code clean-ups.

Making Symfony compatible with PHP 7.2¶ We started working on PHP 7.2 compatibility more than one year ago and we've been testing Symfony with PHP 7.2 successfully for some months thanks to our tests on Travis CI. All Symfony versions, from 2.7 to the upcoming 3.4 and 4.0, are now fully compatible with PHP 7.2. The changes needed to achieve this full PHP 7.2 compatibility were minor but spread across our entire code base: #20859, #21389, #22707, #23711, #24509, etc.
