I agree with @c42f that we should make a couple of releases (with and without the deprecation).

What's the process with that these days? Edit the version in the Project.toml file and then use JuliaRegistrator?

[c42f]

Yep it's that simple: change the version number in Project.toml and trigger JuliaRegistrator with

@ JuliaRegistrator register()

on an issue or commit comment (obviously fix the formatting to actually trigger the bot)

Tagbot allows you to write release notes in the issue too, though you need to include them with every JuliaRegistrator invocation; see my clumsy attempt at #616. I'm somewhat inclined to let Tagbot create the release notes in the future because it saves a lot of work and Tagbot does a pretty good job.
