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 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
