Full commit
This is the CHANGES file of the RefTeX distribution, version 4.10 

Here are the more important changes made to RefTeX since initial release.
Minor bug fixes are not mentioned.

Version 4.10
   - Renamed `reftex-vcr.el' to `reftex-dcr.el' because of conflict
     with `reftex-vars.el' on DOS machines.
   - New options `reftex-parse-file-extension' and

Version 4.09
   - RefTeX maintaines an "Index Phrases" file in which phrases can be 
     collected.  When the document is ready, RefTeX can search all
     these phrases and assist indexing all matches.
   - The variables `reftex-index-macros' and
     `reftex-index-default-macro' have changed their syntax slightly.
     The "repeat" parameter has move from the latter to the former.
     Also calls to `reftex-add-index-macros' from AUCTeX style files
     need to be adapted.
   - The variable `reftex-section-levels' no longer contains the
     default stuff which has been moved to a constant.
   - Environments like theorems can be placed into the TOC by putting
     entries for "begin{theorem}" in `reftex-setion-levels'.
Version 4.07
   - New option `reftex-toc-max-level' to limit the depth of the toc.
     The `t' key in the *toc* and *RefTeX Select* buffers also changes
     this variable.
Version 4.06
   - `reftex-section-levels' can now also contain functions to compute 
   - Multiple `thebibliography' environments recognized.
Version 4.04
   - New option `reftex-index-default-tag' implements a default for queries.
Version 4.02
   - macros ending in `refrange' are considered to contain references.
   - Index entries made with `reftex-index-selection-or-word' in TeX
     math mode automatically get enclosing `$' to preserve math mode.
     See new option `reftex-index-math-format'.  Requires AUCTeX.
Version 4.01
   - New command `reftex-index-globally' to index a word in many
     places in the document.  Also available from the index buffer with
     the `&' key.
   - The first item in a @code{reftex-label-alist} entry may now also
     be a parser function to do non-standard parsing.
   - `reftex-auto-view-crossref' no longer interferes with
Version 4.00
   Many changes - too much to document them in detail here.  In summary:
   - RefTeX has been split into 11 smaller lisp files.
   - Index support, along with many new user options.
   - The selection of keys for `\ref' and `\cite' now allows to
     select multiple items by marking entries with the `m' key.
   - fancyref.sty support.
Version 3.38
   - `reftex-view-crossref' no longer moves to find a macro.
   - Bug fix for XEmacs selection process.
Version 3.36
   - New value `window' for option `reftex-auto-view-crossref'.
Version 3.35
   - ISO 8859 Latin-1 chars are converted to ASCII to derive better labels.
     This takes back the related changes in 3.34 for safety reasons.
   - Fixed bug with non-existing string-width function in XEmacs.
Version 3.34
   - Additional flag in `reftex-derive-label-parameters' to make only
     lowercase labels (default t).
   - All .rel files have a final newline to avoid queries.
   - Single byte representations of accented European letters (ISO-8859-1)
     are legal in labels.  However, general Mule characters are not.
Version 3.33
   - Multiple Selection Buffers are now hidden (names start with a space).
   - Fixed bug with file search when TEXINPUTS was empty.
Version 3.30
   - In `reftex-citation', the regexp can be completed on known cite keys.
   - New keys `a' and `A' in bib selection process to cite all entries.
   - New command `reftex-renumber-simple-labels' to renumber `eq:13' etc.
Version 3.28
   - Auto view crossref for XEmacs uses post-command-hook to restart the
     timer, since itimer restart is not reliable.
   - Option `reftex-bibfile-ignore-list' renamed to `-regexps'.
   - Expansion of recursive tex and bib path rewritten.
Version 3.27

   - Default of `reftex-revisit-to-follow' changed to nil.
Version 3.24
   - New option `reftex-revisit-to-echo'.
   - Interface with X-Symbol (>=2.6) is now complete and stable.
   - Adapted to new outline, which uses overlays.

   - Parse files MASTER.rel made compatible between Emacs and XEmacs.
   - `kill-emacs-hook' and `kill-buffer-hook' now write the parse file.
   - The cursor inside a \ref or \cite macro now triggers automatic
     display of crossref information in the echo area.  See variable
   - AUCTeX interface updates:
     - AUCTeX 9.9c and later notifies RefTeX about new sections.
     - RefTeX notifies AUCTeX about new labels.

Version 3.22
   - `reftex-mouse-view-crossref' is now bound by default at `S-mouse-2'
Version 3.21
   - New options for all faces used by RefTeX.  They're in the
     customization group `reftex-fontification-configurations'.
Version 3.18
   - The selection now uses a recursive edit, much like minibuffer input.
     This removes all restrictions during selection.  E.g. you can now
     switch buffers at will, use the mouse etc.
   - New option `reftex-highlight-selection'.
   - Mouse-2 can be used to select in selection and *toc* buffers.

   - Support for the `varioref' package (`v' key in selection buffer).
Version 3.12
   - There are 3 new keymaps for customization: `reftex-toc-map',
     `reftex-select-label-map', `reftex-select-bib-map'.

     packages like outline, folding, x-symbol, iso-cvt, isotex, etc.

     Goossens, Mittelbach & Samarin, Addison-Wesley 1994) are part of
     RefTeX's defaults.
