Changelog

Sourced from rdoc's changelog.

=== 3.12.2 / 2013-02-24

• Bug fixes
  • Fixed bug in syntax-highlighting that would corrupt regular expressions.
    Ruby Bug #6488 by Benny Lyne Amorsen.
  • Fixed lexing of character syntax (?x). Reported by Xavier
    Noria.
  • Fixed tokenization of % when it is not followed by a $-string type
  • Fixed display of END in documentation examples in HTML output
  • Fixed tokenization of reserved words used as new-style hash keys
  • Fixed HEREDOC output for the limited case of a heredoc followed by a line
    end. When a HEREDOC is not followed by a line end RDoc is not currently
    smart enough to restore the source correctly. Bug #162 by Zachary Scott.

=== 3.12.1 / 2013-02-05

• Bug fixes
  • Fixed an XSS exploit in darkfish.js. This could lead to cookie disclosure
    to third parties. See CVE-2013-0256[rdoc-ref:CVE-2013-0256.rdoc] for full
    details including a patch you can apply to generated RDoc documentation.
  • Ensured that rd parser files are generated before checking the manifest.
