A cool change is that the Core Specification of the Unicode Standard is now released as a static HTML subsite, backed up by an archiveable #PDF of 1,140 pages.
You can now link to specific sections and paragraphs, e.g.
"Unicode is about plain text, see: https://unicode.org/versions/Unicode16.0.0/core-spec/chapter-2/#G642" .
I helped out in a small way with the project to produce the core spec as HTML + PDF. I think it is a marvellous improvement.
