[PHP-DEV] PHP 8.6 Branch Cut - 1 Week Warning

Hi internals,

This is your one‑week warning for the PHP 8.6 branch cut.

Next Tuesday (September 22) we will create the PHP-8.6 branch as part of 
the packaging of PHP 8.6.0RC1. At that point, master will move to PHP 
8.7, and the default expectation will be that changes target PHP 8.7. If 
patches need to be made against PHP 8.6, please ping the PHP 8.6 release 
managers team for review.

The branch cut also marks the hard feature freeze: even features that do 
not require an RFC can no longer be incorporated into PHP 8.6 and will 
need to wait for a future release.

For those of us with karma, the merge workflow for bug fixes will change 
after the branch cut: PHP-8.5 will get merged into PHP-8.6, and PHP-8.6 
into master. Please keep an eye on GitHub when merging bug fixes to 
ensure they land on the correct branches.
