## #108653 — Nikita Popov — 2020-02-18T10:54:36+00:00

Hi internals,

I'd like to present an overview proposal on how to deal with opt-in
backwards-incompatible changes:

https://github.com/nikic/php-rfcs/blob/language-evolution/rfcs/0000-language-evolution.md

This proposal is intended as a discussion starting point, so we can decide
on the general direction we want to pursue. If we have a rough consensus,
then a second proposal could sort out the details of a particular approach.

A pull request is available to leave inline comments:
https://github.com/php/php-rfcs/pull/2

Regards,
Nikita
