The Working Group had its first meeting 18-19 June 1991, and has now met about 30 times - two to three times per year - in joint technical sessions with US committee J16. A number of countries have been represented at the meetings: Australia, Canada, Denmark, Finland, France, Germany, Ireland, Japan, Netherlands, New Zealand, Norway, Russia, Sweden, Switzerland, UK, and the USA.

SUMMARY OF ACCOMPLISHMENTS

The C++ first CD was ballotted between May 28 and September 28, 1995 (CD 14882, SC22 N1824). Ballot responses included a large number of substantive comments. WG21 spent three meetings (November 1995, March 1996, and July 1996) resolving the comments, and after the July meeting voted to submit a new working draft for a second CD ballot.

The second (Final) CD for C++ was out for ballot in SC22 N2356 ending 1997-06-09. The text of the CD is available in http://www.open-std.org/jtc1/sc22/open/n2356/ .

The C++ standard was out for FDIS ballot ending 1998-06-23.

The C++ standard was published 1998-09-01 by ISO ITTF as ISO/IEC 14882:1998.

The Technical Report type 3 on C++ Performance was proposed in SC22 N2831 and JTC 1 N5784 ballot ending 1999-06-29. It was approved by JTC 1 as project JTC1.22.18015 with summary of voting as recorded in SC22 N2952. It was approved as a TR in 2004.
