RDoc 2.2.0 now is available!

This version essentially aims to fix a number of bugs and to provide
some small enhancements.  I've highlighted a few cool things about the
release in a blog post at

This is the full change list:
=== 2.2.0 / 2008-09-19
This version includes some significant enhancements to ri.  See RI.txt
for
documentation about ri.

* 5 Major Enhancements
  * More extensive unit tests (special thanks to Chris Lowis for
contributing
    a test).
  * Made ri twice as fast for the most common use case of displaying
    information for a class or a fully-qualified method
    (i.e., ri Array#flatten, after ri has created a cache the first time
that
    it runs).
  * Made ri many times faster when searching for an unqualified method
(i.e.,
    ri read, again after the first such search has populated ri's cache)
  * Changed ri to do regular expression searches for unqualified
methods;
    now, a regular expression for a method can be passed to ri on the
    command-line.
  * Added an interactive mode to ri (patch by Daniel Choi).  Now, when
ri
    is given a -i argument, it will allow the user to disambiguate
    unqualified methods if more than one is present and also will allow
a
    user to get information for a class' method.

* 8 Minor Enhancements
  * RDoc now adds the package title to the web pages that it generates
    for files and classes/modules, which helps them appear better in
    search engine results.
  * RDoc now automatically generates cross-reference links for classes
and
    methods specified relative to the global namespace (i.e.,
::A::B::C#method).
  * All built-in templates now output valid, strict XHTML.
  * The documentation is slightly better organized (the markup details
were
    merged into the RDoc module's documentation).
  * Improved rdoc's HTML generation speed by about 20% (on Windows, the
    boost seems larger).
  * Provided an ri command-line option to control its caching behavior.
  * Improved RDoc's documentation.  Added RI.txt to document ri.
  * Allow HTML templates distributed as gems to be loaded with the -T
option,
    just like the standard templates in rdoc/generator/html (so an HTML
    template lib/new_template.rb in a gem can be used with rdoc -T
new_template)

* 25 Bug fixes:
  * Fixed prototype detection in C parser.  Can process ruby 1.8 C files
    again.
  * Fixed the main page for frameless template.  Patch by Marcin
Raczkowski.
  * Fixed the main page for frame templates.  Now, if no main page is
    specified, RDoc will default to the README.
  * Fixed missing stylesheet in generated chm.  Patch by Gordon
Thiesfeld.
  * Fixed the parsing of module names starting with '::'.  Patch by
    Giuseppe Bilotta.
  * Fixed a case where RDoc first would encounter Foo::Bar and then
would
    encounter class Foo.  Previously, RDoc erroneously would have
considered
    that both a Foo class and a Foo module existed.
  * Fix a clase where RDoc would not generate correct cross-reference
links
    to a class contained within a module of the same name (i.e.
RDoc::RDoc)
  * Prevented RDoc from trying to parse binary files, which would
produce
    garbage output.
  * RDoc now correctly converts ' characters to apostrophes, opening
single
    quotes, and closing single quotes in most cases (smart single
quotes).
  * RDoc now correctly converts " characters to opening double quotes
and
    and closing double quotes in most cases (smart double quotes).
  * (c) correctly is converted into the copyright symbol.
  * '&' characters in text now correctly are translated to HTML
character codes.
  * Fixed missing stylesheet in generated chm.  Patch by Gordon
Thiesfeld.
  * Fixed broken method links in the built-in templates.
  * RDoc properly links to files and classes in the one page HTML
template.
  * The kilmer and hefss templates properly syntax highlight when
inlining
    source code.
  * The kilmer and hefss template class pages properly display methods
again.
  * Fixed broken class, file, and method links in the frameless
template.
  * Fixed the clipping of source code in the html and frameless
templates when
    the source code cannot fit into the window; a scrollbar now will
allow
    all of the source code to be viewed.
  * Fixed the missing constant descriptions in the html and frameless
    templates.
  * Fixed the ri command-line options that customize the directories to
be
    searched for documentation.
  * Fixed the XML generator.  Patch by Anthony Durity.
  * Stopped the XML template from generating invalid XML due to
malformed
    embedded ruby.
  * Adding missing information about a class' constants to the XML
template.
  * Fixed the horizontal rule markup (---) so that it correctly adds a
    horizontal rule rather than suppressing all text that follows.
