If you'd like to try the binary distribution we have for linux, it can be also downloaded from the same link above.
This version includes several changes:
Most notably it includes preliminary support for Parrot (Pasm and Pir) syntax highlighting and Perl 6 syntax highlighting.
As I mentioned on #parrot it is very preliminary and naive but I hope by providing the framework someone who knows more about parsing these languages will help connecting Padre to a parser that will allow real syntax highlighting, calltips and contextual help for these languages.
Detailed list of changes are available in the Changes file
As usual comments, bug reports, requests are welcome on the development mailing list and on our trac.
