 Emacs 24.5, earlier -- previous versions, do NOT work

and (main) prover versions:

  Coq 8.9, 8.10, 8.11, 8.12, 8.13 -- tested versions in PG's CI
  Coq 8.4, 8.5, 8.6, 8.7, 8.8     -- previous versions, should work

In the major 4.0 release ** XEmacs compatibility was dropped **

Running on macOS
-------------------

We recommend 24.5+ builds of GNU Emacs, which builds natively on
macOS.  Binaries are available at various websites (e.g.,
http://emacsformacosx.com), or you can build your own by compiling
from the FSF CVS. See the Emacs Wiki at
http://www.emacswiki.org/emacs/EmacsForMacOS for more.

Note that macOS compatibility isn't thoroughly tested.  If you discover
problems, please send a report and/or fix to the PG tracker.  Please
add tips to the wiki page above.


Running on Windows
------------------

Note that Windows compatibility isn't tested by the maintainers.
