JPF (Java Plugin Framework) is a general-purpose plug-in framework
intended to help building scalable, extendable Java applications with
low cost of maintenance. The framework is specially designed to be
easily included into Java project of any kind.

New versions of JPF and JPF-Demo are available for download. Starting
with version 0.5 the status of JPF is considered as "release candidate"
that means that library reached very stable runtime behavior and have
stable API. Further releases will be mostly bug fixing and internal
improvements and optimizations related.

The major changes are:
* Added methods to PluginRegistry to get plug-ins registration report
separately from integrity check report.
* "Documentation generator" tool is now based on JXP (Java scripted
page) templates.
* Added methods to RegistryChangeData interface to help filter
extensions by corresponding extension points.
* Implemented possibility to discover Framework configuration.
* PluginRegistry implementation reworked so that it is now uses SAX XML
parser to process plug-in manifests. Implementation is compatible with
JAXP 1.1 specification and based on the SAX 2 API.
* Greatly improved "hot deploy" function implementation.
* Deprecated and actually removed implementation of some unnecessary
functions. The deprecated methods will be removed with final 1.0
release. The reason is to greatly simplify some implementation aspects
of plug-in registry.
* Greatly improved JPF demo application.
* Many non-significant internal code improvements.
