On the main PHP.net site they've posted the announcement about the release of the latest (and last) Release Candidate of the next major version of the PHP language: PHP 7.2.0 RC6.

The PHP development team announces the immediate availability of PHP 7.2.0 RC6. This release is the sixth Release Candidate for 7.2.0. Barring any surprises, we expect this to be the FINAL release candidate, with Nov 30th's GA release being not-substantially different. All users of PHP are encouraged to test this version carefully, and report any bugs and incompatibilities in the bug tracking system.

This development preview release includes changes to GD image handling, SOAP functionality and core bugfixes. You can download this latest release for testing with your own applications either via the source QA site or the Windows QA site for the Windows executable.
