Last change on this file since 1417 was 213, checked in by mitsubishi-htm, 12 years ago

A final release, as planned

  • Migrate to HTM 5.1
  • For VC project files, only VC9 file is updated
  • To be used as an additional anchor for CE1.h for 3rd JCTVC meeting at Geneva
  • Property svn:eol-style set to native
