Which status does a PSR have once the PHP-FIG has finally approved it?

At the PHP-FIG, a PSR goes through several phases: Pre-Draft, Draft, Review and finally Accepted. Only with the status Accepted is the recommendation officially approved, so libraries can rely on it. In Draft and Review the content may still change, which is why such drafts should be used in production code only with caution. Abandoned, on the other hand, means that a proposal was given up; outdated standards that were once accepted, such as PSR-0, carry the status Deprecated.
