 - Optimization: stringify variables passed to canonpath [David Golden]

 - Optimization: Use internal guts when constructing Dirs from
   Dirs, instead of concatenating and splitting them again with
   File::Spec. [David Golden]

 - Fix grammar error in docs. [Karen Etheridge]

 - Implement a 'split' parameter for the slurp() method [suggested by Yanick \ 
Champoux]

 - In docs, replace unicode MINUS SIGN with ascii HYPHEN-MINUS [Randy Stauner]

0.29  Mon Dec 17 23:55:07 CST 2012

 - Add components() method, which returns directory names (and
   filename, if this is a File object) as a list.

 - Fix a test failure on non-Unix platforms, the 07-recurseprune.t
   test was written in a Unix-specific way.

0.28  Sat Dec 15 21:40:17 CST 2012

 - Fix test failures when run as root - they were relying on
   permissions failures, but permissions never fail as root. [Spotted
   by AAR and Chris Williams]

 - Add links in docs to the other modules we rely on & talk about in
   the docs.  Makes for easier viewing through search.cpan.org /
   MetaCPAN. [David Precious]

 - Fixed some misleading variable names in docs. [RT#81795] [Pau Amma]

0.27  Sat Dec  8 19:24:15 CST 2012

 - Added pruning support in dir->recurse(). If recurse callback
   returns $item->PRUNE, no children of this item will be
   analyzed. [Marcin Kasperski]

 - Documented 'basename' method for directories. [Fabrice Gabolde]

 - Added traverse_if() function, which allows one to filter children
   before processing them. [Marcin Kasperski]

 - Added tempdir() function. [cho45]
