PHP7, the new version of the programming language Symfony is built with, will be released at the end of the year. The recent release of its third beta has brought us another step closer to the final stable release.

During these last past months, we've been working very hard to achieve full PHP7 compatibility. This effort accelerated during the past weeks and we're glad to announce that all Symfony maintained branches are now 100% compatible with PHP7.

Our PHP7 compatibility journey started on February 2015, when Nicolas Grekas added to the list of tested PHP engines on Travis CI (see commit). After that, a lot of pull requestsfollowed to fix PHP7 compatibility for Symfony components.

Some of these changes were related to the new reserved keywords, which prevents you from using, , , , , and as the name of your classes (see PR #14472). This forced us to rename the , and constraints (see PR #14228).

Another big change was related to the new interface introduced by PHP7 and which is implemented by all the internal error and exception classes. Our exception handler needed to be updated for this new interface (see PR #14959).

Lastly, we've just removed from the list of PHP engines which can silently fail. This means that Symfony no longer accepts changes that break PHP7 compatibility, not even in the master branch where the upcoming Symfony 3 is being developed.
