Revision history for Pod-Abstract 0.20 03/01/2010 Removed usage of UNIVERSAL isa and can as functions, will correct a deprecation warning with Perl 5.11. Fixed a bug with nodes->from_pod which did not work as documented. Corrected some minor errors with documentation formatting. Added test coverage for from_pod. 0.19 21/06/2009 Added =head1 NAME blocks to those modules missing them. Added some additional Pod. Added "Task::Weaken" dependancy to ensure that the target platform has a working "weaken" in their Scalar::Util 0.18 08/06/2009 Replaced "=" operator with "eq", added the full set of Perl compatible binary comparison operators (eq and friends, == and friends). This will break your code if you used the "=" operator in 0.17, you will need to change it to "eq". 0.17 26/05/2009 Added Union and Intersection operators to paths (conjunction of multiple simple paths). Support for multi-name selectors in paths. Fix for memory leak. Testing of pPath expressions. Added "=" operator with support for combinational matching (any node on left expression = any node on right expression) 0.16 11/05/2009 Changed constant declarations to allow older Perl 5.6 constants. Removed body components from heading and label attributes in BuildNode, which would cause ->select to behave incorrectly on newly added nodes. 0.15 12/03/2009 Improved documentation. Added some real documentation for Pod::Abstract::Path. Had an attempt at fixing the compile issues for Perl 5.6. No significant changes in function. 0.14 03/03/2009 Improved paf filter suite. Bug fixes. paf defaults to "load as perldoc". Allow mandatory positional arguments for filters. 0.10 28/02/2009 Package build with functional library and "paf" utility.
