Hi Lisandro, Indeed those were missed in our check list. We'll check and make sure they get into the release.

Please use the newer version of the document. We are hopeful that it will get ratified this week. Afterward, we should check against the official 4.1 document. We try to comb through the changes that affect implementations. If you see anything we miss, let us know. -- Hui ________________________________ From: Lisandro Dalcin <dalcinl(a)gmail.com> Sent: Thursday, November 2, 2023 8:55 AM To: Zhou, Hui <zhouh(a)anl.gov> Cc: devel(a)mpich.org <devel(a)mpich.org> Subject: Re: [mpich-devel] Cancelling this week's MPICH development update call On Thu, 2 Nov 2023 at 16:20, Zhou, Hui <zhouh(a)anl.gov<mailto:[email protected]>> wrote: Hi Lisandro, If you see anything we miss, please alert us.

Hi Lisandro, Yes, the plan is to release mpich-4.2b1 next week with full support for the upcoming MPI 4.1 specification. All the pull-requests related to MPI 4.1 and need to be merged before the 4.2b1 release is tracked in https://github.com/pmodels/mpich/projects/23. If you see anything we miss, please alert us. -- Hui ________________________________ From: Lisandro Dalcin via devel <devel(a)mpich.org> Sent: Thursday, November 2, 2023 2:56 AM To: devel(a)mpich.org <devel(a)mpich.org> Cc: Lisandro Dalcin <dalcinl(a)gmail.com> Subject: Re: [mpich-devel] Cancelling this week's MPICH development update call Dear Hui, I need some clarification.

Could you please add "cc @dalcinl" in any upcoming MPICH PR related to MPI-4.1? Or at least add a "MPI-4.1" tag (or whatever name you like) to these PR? . mpi4py already wraps the 4.1 stuff and has preliminary tests in place. I would like to keep things in sync.
