=== 0.6.2 / 2010-01-30

* Updated the documentation.

=== 0.6.1 / 2010-01-04

* Changed the hard-dependency on the 'structured_warnings' RubyGem to a soft-dependency - which lets Rubytree still
  work if this RubyGem is not available.  The rationale for this is that we should not require the user to install a
  separate library just for one single edge-case function (in this case, to indicate a deprecated method).  However, if
  the library _is_ available on the user's system, then it will get used.

=== 0.6.0 / 2010-01-03

* Fixed the bug#22535[http://rubyforge.org/tracker/index.php?func=detail&aid=22535&group_id=1215&atid=4793] where the
  depth method was actually returning height+1 (not the depth).

* Marked the Tree::TreeNode#depth method as *deprecated* (and introduced the run-time dependency on
  structured-warnings[http://github.com/schmidt/structured_warnings] gem).

=== 0.5.3 / 2009-12-31

* Cleanup of the build system to exclusively use Hoe.
* Modifications and reformatting to the documentation.
* No user visible changes.

=== 0.5.2 / 2007-12-21

* Added more test cases and enabled ZenTest compatibility for the test case
  names.

=== 0.5.1 / 2007-12-20

* Minor code refactoring.

=== 0.5.0 / 2007-12-18

* Fixed the marshalling code to correctly handle non-string content.

=== 0.4.3 / 2007-10-09

* Changes to the build mechanism (now uses Hoe).

=== 0.4.2 / 2007-10-01

* Minor code refactoring. Changes in the Rakefile.
