How to see old versions of Cheat Sheet?

I uploaded a customizable file to Thingiverse (
https://www.thingiverse.com/apps/customizer/run?thing_id=7323176). It
didn't render in preview for me. I was wondering if I was using commands
that were too new for Thingiverse's version of customizer. Apparently,
they're still running 2015.03 (see:
https://www.thingiverse.com/thing:3958002). That got me to wondering when
the "$preview" command came out. So I went to the Cheat Sheet website, and
changed the version to 2015.03, and nothing changed. It still says 2021.01
at the top of the webpage, even when you change the URL (see:
https://openscad.org/cheatsheet/index.html?version=2015.03).

Question 1: When did $preview come out?
Question 2: How do I see old versions of the cheatsheet?
Question 3: Now that Thingiverse has been sold/acquired again, can someone
please petition the new owners to update their version of OpenSCAD?

Thanks.

There's no direct match to releases, but the full history is at
https://github.com/openscad/openscad.github.com/commits/main/cheatsheet/index.html

Question 3: Now that Thingiverse has been sold/acquired again, can
someone please petition the new owners to update their version of
OpenSCAD?

Some mails were exchanged a while ago, but I suppose they have to
sort out quite a bit more than just the Customizer. There's at least
hope as in "we'd like to work on it, but...".

ciao,
Torsten.

That's the history for the cheat sheet that a release will present.  The
history for cheat sheets for snapshots is at
https://github.com/openscad/openscad.github.com/commits/main/cheatsheet/snapshot.html
