Hi all, There will be no virtual meeting today. Bill is getting the last few things merged into the mpi-4.x branch and will be creating the RC over the next day or two. I’ll get that divided up for people to review and we’ll discuss that next week. Thanks, Wes

Dear all, I’d like to announce the following Errata issue/PR for inclusion in the MPI 4.0 RC and voting at the December meeting. # 320: Improper placement of figures and use of colors for text in MPI-4.0 Section 8.6.2 Example 8.10 Issue: https://github.com/mpi-forum/mpi-issues/issues/320 PR: https://github.com/mpi-forum/mpi-standard/pull/304 Changes: https://github.com/mpi-forum/mpi-standard/pull/304/files pdf: https://github.com/mpi-forum/mpi-issues/files/5487463/mpi40-report_Issue320… See Section 8.6.2, pages 386-387 (pdf 426-427). I still plan to substitute the "blue" and "red" by "solid arrows" and "dashed arrows" in text and figures.
