I just committed version 1.4.0 of rst.el. Here are the user visible
Add support for `imenu` and `which-func-mode`. Remember setting
`which-func-modes` for this feature to work.
Automated calculations of section title faces replaced by `defface`.
The latter replaces the calculated background colors of section titles
by explicit `defface`\s. This may break existing customizations
although these faces are not customizable really. I'm interested in
feedback on this.
This version - or may be a slightly refactored one - will be included
in Emacs 24.3. This will replace a very old version of `rst.el` up to
the Emacs 24.2 distribution.
