I am doing this review for documentation purposes. In addition to the line comment the Copyright lines need to be updated, which is this step in releasing.md:

When the year changes, e.g. between 2019-12 and 2020-03 releases, an update of the copyright year is required with a very smart search&replace. A good replacement is /, 2021/, 2022/ excluding *.svg

And NewAndNoteworthy entry for platform in all epp.website.xml needs to be updated. I will add an explicit step to the releasing.md for this:

NewAndNoteworthy entry needs updating which has a slightly different pattern than other versions

I am providing a PR momentarily that includes these changes and I have completed the M1 specific part of the checklist in #251
