 This was compounded in 2009 when IMS GLC withdrew the Version 2.1 draft and advised the user community that the only version "fully endorsed" by IMS GLC was 1.2.1, in effect also deprecating Version 2.0.Despite this, after several more drafts, 2.1 was finalized and released in 2012.The current version is 2.2, which was finalized in 2015, and has subsequently had two minor revisions, 2.2.1 and 2.2.2, the latest of which was in November 2017.
