84 <li>Implemented possibility to discover Framework configuration.</li>
85 <li>PluginRegistry implementation has been 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.</li>
86 <li>Greatly improved "hot deploy" function implementation.</li>
87 <li>Deprecated and removed some unnecessary functions. The deprecated methods will be removed with at the time of the final 1.0 release. This was to greatly simplify some implementation aspects of <a href="api/org/java/plugin/registry/PluginRegistry.html">PluginRegistry</a>.</li>

98 Change log:
99 <ul>
100 <li>Added utility methods to <a href="api/org/java/plugin/registry/PluginRegistry.html">PluginRegistry</a> and PluginDescriptor interfaces that simplify the checking of availability of various plug-in elements. <strong>Thanks to Lukasz Grabski</strong>.</li>

118 <li>Introduced the <a href="api/org/java/plugin/ObjectFactory.html">ObjectFactory</a> class that is used to get instances of main Framework objects like <a href="api/org/java/plugin/PluginManager.html">PluginManager</a>, <a href="api/org/java/plugin/registry/PluginRegistry.html">PluginRegistry</a> and <a href="api/org/java/plugin/PathResolver.html">PathResolver</a>.</li>
119 <li>The Framework API has been significantly restructured to make it much more flexible, consistent and extendible. To start using version 0.7 existing application should be modified. Most changes are related to moving classes between packages.</li>
120 <li>Improved documentation tool - added printing of documentation notes for extension point parameter definitions. <strong>Thanks to Jeff Brown</strong>.</li>
121 </ul>
122 </p>
123 <h3>Version 0.8</h3>
124 <p>
125 Status: <strong>done</strong><br />
126 Release date: <strong>2005-12-10</strong>
127 </p>
128 <p>
129 Change log:
130 <ul>
131 <li>Introduced the <a href="api/org/java/plugin/registry/UniqueIdentity.html">UniqueIdentity</a> interface into the registry API to mark all plug-in elements that may have a unique identifier (<a href="api/org/java/plugin/registry/PluginDescriptor.html">PluginDescriptor</a>, <a href="api/org/java/plugin/registry/PluginFragment.html">PluginFragment</a>, <a href="api/org/java/plugin/registry/PluginPrerequisite.html">PluginPrerequisite<a/>, <a href="api/org/java/plugin/registry/Library.html">Library</a>, <a href="api/org/java/plugin/registry/ExtensionPoint.html">ExtensionPoint</a> and <a href="api/org/java/plugin/registry/Extension.html">Extension</a>).</li>
132 <li>Introduced a special implementation of <a href="api/org/java/plugin/PathResolver.html">PathResolver</a> that transparently makes shadow copies of plug-ins before resolving them to the application. Among other things this helps to avoid locking of JAR files by the application since this prevents "hot updating" of plug-ins. For implementation details and configuration options see the javadoc for the <a href="api/org/java/plugin/standard/ShadingPathResolver.html">org.java.plugin.standard.ShadingPathResolver</a> class.</li>
133 <li>Introduced the "Single File Plug-in" Ant task to package plug-ins as ZIP files that may be run directly without further modification (part of JPF Tools).</li>
134 <li>Introduced the "Plug-in Info" Ant task to read the plug-in ID and version from the manifest file into project properties (part of JPF Tools).</li>
135 <li>Introduced the "JPF Boot" library to simplify running JPF based applications.</li>
136 <li>Added Path and version info elements to jpf*.jar manifests. Version numbers are no longer included in JAR file names.</li>
137 <li>Introduced utility class <a href="api/org/java/plugin/util/IoUtil.html">org.java.plugin.util.IoUtil</a> to handle I/O, File and URL manipulations.</li>

143 Release date: <strong>2006-02-23</strong>
144 </p>
145 <p>
146 Change log:
147 <ul>
148 <li>Added getMatch() method to <a href="api/org/java/plugin/registry/PluginRegistry.html">PluginRegistry</a> interface to get complete access to full information in manifest. <strong>Thanks to Sebastian Kopsan for the idea.</strong></li>
149 <li>Introduced utility method readManifestInfo() to <a href="api/org/java/plugin/registry/PluginRegistry.html">PluginRegistry</a> interface to read basic manifest info (plug-in ID, version and such).</li>
150 <li>ShadingPathResolver now uses relative paths whenever that possible. This allows, for example, run JPF based application from different network locations without disturbing shadowed plug-ins.</li>
151 <li>Minor internal improvements in <a href="boot.html">JPF-Boot library</a>.</li>
152 <li>Now <a href="boot.html">JPF-Boot library</a> passes given command-line arguments to the application. To support this function, <a href="api/org/java/plugin/boot/ApplicationPlugin.html">ApplicationPlugin</a> API and JPF-Boot starting up arguments have been changed.</li>
153 <li>JPF documentation was reviewed and updated by <strong>Michael Dawson</strong> (this work is in progress now).</li>
154 <li>Added support for splash window in <a href="boot.html">JPF Boot library</a>. See additional <a href="config.html">configuration</a> parameter in <a href="api/org/java/plugin/boot/Boot.html">Boot</a> class.</li>
155 <li>Fixed bug in StandardPathResolver.resolvePath() method. <strong>Thanks to Sebastian Kopsan.</strong></li>

170 <li>Added probeParentLoaderLast configuration parameter to <a href="api/org/java/plugin/standard/StandardPluginLifecycleHandler.html">StandardPluginLifecycleHandler</a>. This allows regulating of plug-in classloader delegation behavior. <strong>Thanks to Richard Bjarne (rjvduijn) for an idea.</strong></li>

179 <li>Improved "Plug-in Info" Ant task to make it consistent with <a href="api/org/java/plugin/registry/PluginRegistry.ManifestInfo.html">PluginRegistry.ManifestInfo</a> interface. This change may break existing Ant scripts that uses jpf-info Ant task.</li>
180 </ul>
181 </p>
182 <h3>Version 0.11</h3>
183 <p>
184 Status: <strong>done</strong><br />
185 Release date: <strong>2006-06-29</strong>
186 </p>
187 <p>
188 Change log:
189 <ul>
190 <li>To the <a href="api/org/java/plugin/boot/DefaultApplicationInitializer.html">DefaultApplicationInitializer</a> class from <a href="boot.html">JPF-Boot library</a> added possibility to provide lists of plug-ins to be included/excluded from application (white and black lists). <strong>Thanks to Jonathan Giles for an idea.</strong></li>
191 <li>All <a href="tools.html">Ant tasks</a> improved to be able to work with single file plug-ins (JAR'ed or ZIP'ed). <strong>Thanks to Prashant M. R.</strong></li>
192 <li>Added possibility of advanced control of application splash screen in <a href="boot.html">JPF-Boot library</a>. See additional <a href="config.html">configuration</a> parameters and new <a href="api/org/java/plugin/boot/SplashHandler.html">org.java.plugin.boot.SplashHandler</a> interface.</li>
193 <li>main() method in <a href="boot.html">JPF-Boot library</a> is now refactored into several separate methods to allow more accurate controlling of application bootstrap procedure. Among other benefits, this allows to write unit tests for plug-ins and JPF based applications.</li>
194 <li>Improved <a href="boot.html">JPF-Boot library</a>. Implemented more flexible boot configuration lookup procedure. <strong>Thanks to Chris Ward.</strong></li>
195 <li>Added "reverse-lookup" attribute to the "import" tag. Setting this attribute to "true" allows imported plug-in to see classes in depending plug-in. This flag helps creating plug-ins that can see classes in other plug-ins not depending on them. This feature is very similar to Eclipse' "buddy class loading" behavior. To make this new function available in your plug-in manifests, refer to new version of <a href="dtd.html">DTD (0.6)</a>.</li>
196 <li>Improved error logging in <a href="api/org/java/plugin/standard/StandardPluginManager.html">StandardPluginManager</a> and <a href="api/org/java/plugin/standard/StandardPluginClassLoader.html">StandardPluginClassLoader</a>. <strong>Thanks to Peter van der Winkel.</strong></li>

228 <li>Plug-in <a href="dtd.html">manifest DTD</a> version number changed to 1.0 All references to previous versions are mapped to this one now.</li>
229 <li>Previously deprecated API has been removed from code.</li>
230 <li>Improved Splash Screen API in <a href="boot.html">JPF-Boot</a> library. It is now allows more flexible handling of splash screen behavior and <a href="config.html">configuration</a>.</li>
