RFC
“PHP releases have always been done spontaneously, in a somehow chaotic way. Individual(s) decided when a release will happen and what could or could fit in. Release managers role are unclear and the way to nominate them is not clearly defined either.
The goals of this RFC aim to solve these issues while giving to us, our users and 3rd parties (distributions, contributors, etc.) more visibility and the ability to actually have a roadmap, or plan developments.”
Felipe Pena, Etienne Kneuss, Stanislav Malyshev, Gustavo André dos Santos Lopes, David Soria Parra, Christian Stocker, Rob Richards, Pierre Joye, Zeev Suraski, Ilia Alshanetsky
