Release Notes: The stack model has been revised to speed things up.
Release Notes: The PathPattern class now accepts wildcards in directory names and any-path wildcards (such as "/**/*.class"). The files are enumerated by PathPattern.enumerateFiles() method using a lazy search approach. Plus, this class now inherits from the Pattern class with all consequences. Some additions were also made to WildcardPattern and RETokenizer. Incompatibility with Perl character classes has been fixed.
Release Notes: This release adds the WildcardPattern class, which accepts a simple wildcard syntax. Two shorthand methods were added to the Pattern class: Pattern.matches(String) and Pattern.startsWith(String). A backreference bug and an incomlete matching bug were also fixed..
Release Notes: A unicode notation bug was fixed. This bug caused a PatternSyntaxException to be thrown when patterns like "\uHHHH" were input.
Release Notes: Major bugs have been fixed, and some methods have been added to the API.
