Here's what's new in 4.0 from 3.21 (from 'NEWS' file in GNU Texinfo
4.0)

> 4.0 (28 September 1999)
> * Language:
>   . New command @anchor for cross references to arbitrary points.
>   . New commands @documentlanguage sets the main document language,
>     and @documentencoding sets the document input encoding (although not
>     much is done yet with either).
>   . New command @pagesizes allows limited control of text area for typesetting.
>   . New command @acronym for abbreviations in all caps, such as `NASA'.
>   . New command @alias for simple command aliases.
>   . New command @definfoenclose for better control of info output.
>   . New commands @deftypeivar for typed instance variables of a class
>     and @deftypeop for typed operations of a class.
>   . New command @novalidate suppresses cross-reference checking and (in
>     TeX) auxiliary file creation.
>   . New commands @setcontentsaftertitlepage and
>     @setshortcontentsaftertitlepage to force printing the table of
>     contents after @end titlepage.  Also, @contents and @shortcontents
>     themselves can now appear at the beginning of the document as
>     well as the end.
>   . New markup commands: @env (for environment variables), @command (for
>     command names), @option (for command-line options).
>   . New commands @smallformat and @smalldisplay, a la @smallexample.
>   . New command @exampleindent to set indentation of example-like
>     environments a la @paragraphindent.
>   . @uref takes an optional third argument of text to show instead of
>     (rather than in addition to) the url for info and dvi output.
>   . @footnote works in an @item for a @table.
> * texinfo.tex:
>   . latest version always at ftp://ftp.gnu.org/gnu/texinfo.tex (and mirrors).
>   . implements @macro.
>   . implements @paragraphindent (except asis).
>   . @emph and @i use true italic type (cmti) instead of slanted (cmsl).
>   . implements pdf output when run with pdftex.
>   . better support for internationalization via txi-??.tex files.
> * makeinfo:
>   . supports HTML output with the --html option.
>   . implication of --html: @top nodes should be wrapped in @ifnottex
>     rather than @ifinfo.  @ifinfo conditionals are not expanded with --html.
>   . new option --number-sections to output chapter/section numbers.
>   . dashes and quotes are not treated specially in node names.
>   . new option --commands-in-node-names to allow @-commands in node names.
>     (Not implemented in TeX, and most likely never will be.)
>   . @emph output uses _underscores_.
>   . @image looks for .png files before .jpg.
>   . only output `Making ... file' line when verbose.
>   . allow -v as synonym for --verbose.
>   . new command line options to specify which conditionals to process
>     (but --iftex is not fully implemented).
>   . warns if @var contains any of ,[]().
>   . @quote-arg implicitly done for all one-argument macros, so commas in
>     the argument text are allowed.
>   . \\ required in macro body to get single \, no other `escapes' defined.
> * info:
>   . ISO Latin 1 characters are displayed and input as-is by default.
>   . new option --vi-keys to enable vi-like and less-like key bindings.
>   . new command S does case-sensitive searching.
>   . new commands C-x n and C-x N repeat last search, respectively, in the
>     same and in reverse direction, without prompting for the string.  These
>     commands are bound to n and N under --vi-keys, like in Less.
>   . new command G menu1 menu2 ... searches for menu items from (dir),
>     as allowed on the command line.
>   . new command O (capital o, not zero) goes directly to the node that
>     describes command-line options.
>   . new command-line option --show-options causes the node which
>     describes command-line options to be the first node displayed.
>   . M-prior and M-DEL do new command info-scroll-other-window-backward.
>   . / searches like s does.
>   . If the search string includes upper-case letters, in both incremental
>     and non-incremental search, the search is case-sensitive.
>   . S searches case-sensitively even if the search string is all
>     lower-case.
>   . - makes the argument negative (so e.g. `- /' searches backward).
>   . l restores point in the window returned to.
>   . SPC/DEL do not move outside the current document.
>   . foo.info is found before foo.
>   . `info foo --index-search=bar' now searches for bar in foo's index.
>   . support for files compressed with bzip2.
> * install-info:
>   . handles gzipped dir files.
>   . sort entries into alphabetical order.
>   . install direntries only in preceding dircategory, not in all.
>   . --delete does not require the info file to exist.
>   . --delete can handle XEmacs-style dir entries.
> * texi2dvi:
>   . bug fixed: now uses only the @iftex and @tex parts of the source.
>   . process LaTeX source as well as Texinfo source.
>   . output PDF (using pdftex) with new option --pdf.
>   . handles --OPTION=ARG style of command line arguments.
>   . new option --batch for progress reports but no interaction.
>   . new option --clean to remove all auxiliary files.
>   . new option --quiet for silence (unless there are errors).
>   . new option -I for specifying directories for @include to search.
>   . handles LaTeX files (running BibTeX etc.).
> * Fixes to util/gen-dir-node and util/fix-info-dir (formerly util/update-info).
> * Distribution:
>   . Man pages included.
>   . Czech and Norwegian message translations.
>   . Various translations for texinfo.tex fixed words included.
>   . DJGPP support.
