I remember these three:

- `tab-width`
- fontification in example blocks (
https://git.savannah.gnu.org/cgit/emacs/org-mode.git/commit/?id=9daad41cc)
- `org-fold-core-style` changing to `text-properties` (from `overlays`)
broke custom code I had for coloring links.

That's also a good idea, but I don't remember being bitten by changes in
emacs itself. It might help emacs adopt better defaults for new users
though, as the backward compatibility of emacs makes its UX terrible for
new users.

I don't care about "important changes" though, I just want the breaking
changes ... I guess I should allocate the needed time for reading this
anyway.

Thanks.
