The Erlang doc mirror linked here has been updated to include the R22.0 docs.
Note that some of the internal links and labels say “ERTS-10.4” and “Version 10.4” instead of “ERTS-11.0” and “Version 11.0”. This is an error. The docs refer to ERTS 11.0 but that detail seems to not have been updated when these docs were generated (whoops!). I was looking at fixing that throughout the docs and links, but it turns out to be a lot more complicated than I’m willing to deal with because of the number of references that include the string “10.4” (and some of them are in PDFs and other things more annoying to update than HTML pages). When the R22.1 docs come out that will probably be fixed and I’ll update to avoid confusion in the distant future.
