Here is a patch against the changes.html file:

2006-01-31  Mark Wielaard  <mark@klomp.org>

	* htdocs/gcc-4.1/changes.html (Java): New section describing
	core library updates for 4.1.

OK to commit?
(Is it correct that these are only available through CVS?)

The original also had a list of all the people that made this possible
(see below). But it seems that is not normally done in the changes
files. Is there an appropriate place to credit the classpath/libgcj
hackers for 4.1?

Cheers,

Mark

+	    of the SizeRequirements utility class and caching for more

+
+	    <li>Improved accessibility support for Swing.</li>
+
+	    <li>Significant progress has been made in the
+	    implementation of the javax.swing.plaf.metal.* package,
+	    with most UI delegates in a working state now.  Please
+	    test this with your own applications and provide feedback
+	    that will help us to improve this package.</li>
+
+	    <li>The GUI demo (gnu.classpath.examples.swing.Demo) has
+	    been extended to highlight various features in our
+	    free-swing implementation. And includes a look and feel
+	    switcher (Metal default, Ocean or GNU).</li>
+
+	    <li>The javax.swing.plaf.multi.* package is now
+	    implemented.</li>
+
+	    <li>Editing and several key actions for JTree and JTable
+	    were implemented.</li>
+
+	    <li>Lots of icons and look and feel improvements for Free
+	    Swing basic and metal themes were added.  Try running the
+	    GNU Classpath Swing Demo in examples
+	    (gnu.classpath.examples.swing.Demo) with:
+	    -Dswing.defaultlaf=javax.swing.plaf.basic.BasicLookAndFeel

+
+	    <li>JMenus were made more compatible in visual and
+	    programmatic behavior.</li>
+
+	    <li>JTable changeSelection and multiple selections
+	    implemented.</li>
+
+	    <li>JButton and JToggleButton change states work properly
+	    now.</li>
+
+	    <li>JFileChooser fixes.</li>
+
+	    <li>revalidate and repaint fixes which make Free Swing
+	    much more responsive.</li>
+
+	    <li>MetalIconFactory implemented.</li>
+
+	    <li>Free Swing Top-Level Compatibility. JFrame, JDialog,
+	    JApplet, JInternalFrame, and JWindow are now 1.5
+	    compatible in the sense that you can call add() and
+	    setLayout() directly on them, which will have the same
+	    effect as calling getContentPane().add() and
+	    getContentPane().setLayout().</li>
+
+	    <li>The JTree interface has been completed. JTrees now
+	    recognizes mouse clicks and selections work, but the
+	    visual implementation is not yet complete.  Work on
+	    expansion and collapsing of the tree nodes is being
+	    implemented.</li>
+
+	    <li>BoxLayout works properly now.</li>
+
+	    <li>Fixed GrayFilter to actually work.</li>
+
+	    <li>Metal SplitPane implemented.</li>
+
+	    <li>Lots of free swing text and editor stuff work now.</li>
+	  </ul>
+	</li>
+
+	<li>Free RMI and Corba
+	  <ul>
+	    <li>The Andrew Watson, Vice President and Technical
+	    Director of the Object Management Group, has officially
+	    assigned us 20 bit Vendor Minor Code Id: 0x47430 ("GC")
+	    that will mark remote Classpath - specific system
+	    exceptions.  Obtaining the VMCID means that GNU Classpath
+	    now is a recogniseable type of node in a highly
+	    interoperable CORBA world.</li>
+
+	    <li>Classpath now includes the first working draft to
+	    support the RMI over IIOP protocol. The current
+	    implementation is capable for remote invocations,
+	    transferring various Serializables and Externalizables via
+	    RMI-IIOP protocol.  It can flatten graphs and, at least
+	    for the simple cases, is interoperable with Sun's jdk
+	    1.5.</li>
+
+	    <li>org.omg.PortableInterceptor and related functionality
+	    in other packages is now implemented:
+	    <ul>
+	      <li> The sever and client interceptors work as required
+	      since 1.4.</li>
+	      <li>The IOR interceptor works as needed for 1.5.</li>
+	    </ul>
+	    </li>
+
+	    <li>The org.omg.DynamicAny package is completed and passes
+	    the prepared tests.</li>
+
+	    <li>The Portable Object Adapter should now support the
+	    output of the recent IDL to java compilers. These
+	    compilers now generate servants and not CORBA objects as
+	    before, making the output depended on the existing POA
+	    implementation. Completing POA means that such code can
+	    already be tried to run on Classpath. Our POA is tested
+	    for the following usager scenarios:
+	    <ul>
+	      <li>POA converts servant to the CORBA object.</li>
+	      <li>Servant provides to the CORBA object.</li>
+	      <li>POA activates new CORBA object with the given Object
+	      Id (byte array) that is later accessible for the
+	      servant.</li>
+	      <li>During the first call, the ServantActivator provides
+	      servant for this and all subsequent calls on the current
+	      object.</li>
+	      <li>During each call, the ServantLocator provides
+	      servant for this call only.</li>
+	      <li>ServantLocator or ServantActivator forwards call to
+	      another server.</li>
+	      <li>POA has a single servant, responsible for all
+	      objects.</li>
+	      <li>POA has a default servant, but some objects are
+	      explicitly connected to they specific servants.</li>
+	    </ul>
+	    The POA is verified using tests from the former
+	    cost.omg.org.</li>
+
+	    <li>The CORBA implementation is now a working prototype
+	    that should support features up till 1.3 inclusive.  We
+	    would invite groups writing CORBA dependent applications
+	    to try Classpath implementation, reporting any possible
+	    bugs.
+	    The CORBA prototype is interoperable with Sun's
+	    implementation v 1.4, transferring object references,
+	    primitive types, narrow and wide strings, arrays,
+	    structures, trees, abstract interfaces and value types
+	    (feature of CORBA 2.3) between these two platforms.  The
+	    remote exceptions are transferred and handled correctly.
+	    The stringified object references (IORs) from various
+	    sources are parsed as required.  The transient (for
+	    current session) and permanent (till jre restart)
+	    redirections work.  Both Little and Big Endian encoded
+	    messages are accepted.  The implementation is verified
+	    using tests from the former cost.omg.org.  The current
+	    release includes working examples (see the examples
+	    directory), demonstrating the client-server communication,
+	    using either CORBA Request or IDL-based stub (usually
+	    generated by a IDL to java compiler).  These examples also
+	    show how to use the Classpath CORBA naming service.  The
+	    IDL to java compiler is not yet written, but as our
+	    library must be compatible, it naturally accepts the
+	    output of other idlj implementations.</li>
