In early July, the IETF Secretariat began archiving previous versions of IETF WG charter files when the charters get updated. When a charter file is updated, it gets renamed as $WGACRONYM$-charter.YYYY-MM-DD.HH where YYYY-MM-DD and HH are the date and time when the subject WG charter file is archived. You can find all of the available archived charters at: http://www.ietf.org/html.charters/HISTORY/ and ftp://ftp.ietf.org/ietf/$WG ACRONYM$/ You can also find links to the archive locations on the "Active IETF Working Groups" Web page (http://www.ietf.org/html.charters/wg-dir.html). Please note that the archiving effort began on July 6th, and is *not* retroactive. Regards, The IETF Secretariat. _______________________________________________ IETF-Announce@ietf.org https://www1.ietf.org/mailman/listinfo/ietf-announce
