To resolve this, I’ve reverted the commits containing MPI-4 text and moved them to a new branch called mpi-4.x.</div><div class=""><br class=""></div><div class="">What this means for everyone else is that if you have a proposal targeted at MPI-4, you will need to make a small change to your pull request on GitHub and you’ll need to make a small change to your workflow when keeping your pull request up to date.</div><div class=""><br class=""></div><div class="">The GitHub change is trivial (THIS WILL TAKE LESS THAN 30 SECONDS SO PLEASE DO IT RIGHT NOW!). There is a good help page from the GitHub folks here: <a href="https://help.github.com/en/articles/changing-the-base-branch-of-a-pull-request" class="">https://help.github.com/en/articles/changing-the-base-branch-of-a-pull-request</a>. Please follow that and change your base branch from mpi-3.x to mpi-4.x.</div><div class=""><br class=""></div><div class="">When updating the pull request (branch) in the future, instead of rebasing onto or merging with the mpi-3.x branch, you’ll use the mpi-4.x branch. Those commands look like this:</div><div class=""><br class=""></div><div class="">For rebasing:</div><div class=""><br class=""></div><div class="">git fetch mpi-forum # Assumes your remote that points to the “official” repository is named mpi-forum</div><div class="">git checkout your_branch</div><div class="">git rebase mpi-forum/mpi-4.x</div><div class=""><br class=""></div><div class="">For merging:</div><div class=""><br class=""></div><div class=""><div class="">git fetch mpi-forum # Assumes your remote that points to the “official” repository is named mpi-forum</div><div class="">git checkout your_branch</div><div class="">git merge mpi-forum/mpi-4.x</div></div><div class=""><br class=""></div><div class="">If you have any questions, feel free to ping me.
