What changed
RIPE policy proposal 2018-04, “PDP Clarification,” was introduced on 16 April 2018 as version 1.0 and marked accepted on 26 September 2018. Its amendment retained the Review Phase maximum of four weeks and added a specific option: if community input was insufficient, the Working Group chair could extend the phase by up to four additional weeks. The proposal framed this as a formal alternative to closing review and restarting with an unchanged proposal. The supplied record contains no later version, but does not establish that no other version existed.
