* Added pluggable look and feel support for BasicTextFieldUI and
BasicToolBarSeparatorUI.
* java.swing.text support for (Default and Layered) Highlighter, FieldView,
PlainView, TabExpander and TabableView added.
* Start of JTable and JTree implementation.
* Internal Swing frames work.
* JMenu and JPopupMenu work.
* New gtk+ AWT FileDialog peer now based on gtk+2.4 or higher.
* java.awt.image LookupTables and kernel support.
* Improved java.awt.image.BufferedImage support.
* AWT 1.0 event model support.
* GNU Classpath now comes with some example programs (see examples/README).
* New javax.crypto, javax.crypto.interfaces, javax.crypto.spec, javax.net,
javax.net.ssl, javax.security.auth, javax.security.auth.callback,
javax.security.auth.login, javax.security.auth.x500, javax.security.sasl
and org.ietf.jgss packages are now officially part of GNU Classpath.
Extra crypto algorithms can be obtained from the GNU Crypto project,
a full TLS implementation is provided by the Jessie project.

* Frame.setIconImage() support.
* AWT GDKGraphics scaling.
* New configure flag --enable-gtk-cairo to build Graphics2D implementation
build on cairo and pangoft2. Enabled at runtime by defining the system
property gnu.java.awt.peer.gtk.Graphics=Graphics2D.
* javax.swing.JSpinner implemented.
* Extensive documentation update for java.util collection classes.
* java.awt.geom completed. Area, Arc2D, Ellipse2D and Line2D implemented.
* GNU JAXP is no longer included with GNU Classpath. Runtime, compiler and
tool integrators are encouraged to directly integrate GNU JAXP.
This release has been tested against GNU JAXP 1.1.

* JColorChooser, JComboBox and JTextField implemented, including example
uses in GNU Classpath Examples swing Demo.
Runtime interface Changes:
* java.lang.Compiler now uses the new java.lang.VMCompiler; there is
a reference implementation that most VMs can use.
* java.lang.VMSystem has a new getenv(String) method and a reference C/JNI
implementation that should work on most Posix like systems.
* java.util.TimeZone has been split into a platform independent class and
a platform dependent class VMTimeZone. GNU Classpath comes with a generic
way to get at the default time zone for Posix/GNU-like platforms.
* [VM]AccessController improvements. In particular it handles
`doPrivileged' calls better, and allows for recursive `doPrivileged'
calls in the same Thread. (see vm/reference/java/security/)
New in release 0.10 (Jul 9, 2004)
* java.net.URL now uses application classloader to load URLStreamHandlers
and reuses URLStreamHandlers when URL is reset (but protocol isn't changed).
* java.io.File.deleteOnExit() implementation.
* java.text multiple new features and bug fixes
(only 2 out of the 1000+ java.text Mauve tests now fail).
* Better (non-black) default AWT System colors.
* AWT lists use GTK treeviews.
* Proper AWT focus management has been implemented.
* Swing menus and scrollpanes are beginning to work.
* Swing splitpanes, dialogs and internal frames were added.
* Swing repainting / double buffering was redone.
* Font management and Pango DPI conversion fixes.
* A lot of AWT imaging and event bugs have been picked out.
* More of javax.swing.text has been implemented.
* javax.swing.Timer has been reimplemented.
* java.security.AccessController has been implemented
(see runtime section).
* The default java.lang.SecurityManager now uses AccessController.
* New java.beans.Statement and Expression implementations.
* Small FileChannel implementation speed improvement for traditional
JNI based systems.
* Regenerated all included JNI header files with gcjh (3.5 CVS),
removes extra extern modifier and allows stricter compiler warning.
* More C code cleanups (-Wmissing-declarations, -Wmissing-prototypes and
-Wstring-prototypes) and jni.h fixes (a few funtion prototype fixes,
made it compilable with C++ compilers and jni.h got renamed from jni.h.in).
* Double.toString() and Float.toString() now work properly on 64-bit
PowerPC systems.
* PPC Darwin, arm, x86-64 and s/390 JNI C code compilation fixes.
* Build system refactored and removed old Japhar specific support.
* The gnu.java.awt.EmbeddedWindow class has been improved, and now
supports embedding AWT windows in other top-level X windows.
This functionality is required by gcjwebplugin.
* gcjwebplugin, an applet viewer that can be embedded into several web
browsers, has been extensively tested with this release of classpath.
(See http://www.nongnu.org/gcjwebplugin/)
* Runtime environments based on GNU Classpath 0.10 should be able to
start up Eclipse 3.0 out of the box now.
Runtime interface Changes:
* VMProcess.destroy() default implementation fixes.
* Fixed the "portable native sync" code; it had been broken since
Classpath release 0.06, when we upgraded to GTK+2.
Classpath's AWT peers use GTK+. GTK+ uses GLIB. GLIB by default uses
the platform's native threading model -- pthreads in most cases.
If the Java runtime doesn't use the native threading model, then you should
specify --portable-native-sync when configuring Classpath, so that GLIB will
use the Java threading primitives instead. (For a superior alternative,
see below.)
* The VM can set the system property
gnu.classpath.awt.gtk.portable.native.sync instead of using the
--portable-native-sync configure-type option.
See doc/vmintegration.texinfo for details.
* We intend that the next release of GNU Classpath will require the VM
to provide JNI 1.2. Classpath currently uses only JNI 1.1, except for
one JNI 1.2 function: GetEnv(), in the JNI Invocation API.
If this poses problems, please raise them on the classpath mailing list.
* The reference implementation of VMThread.holdsLock(Object) now has
a default implementation written in java. For efficiency and to
prevent spurious wakeups a real 'native' runtime version can be supplied.
* There is a new java.security.VMAccessController class that runtimes need
to implement to properly support SecurityManagers. The default
implementation that comes with GNU Classpath makes sure that ANY attempt
to access a protected resource is denied when a SecurityManager is
installed. Which is pretty secure, but also no very useful.
Please see the documentation in
vm/reference/java/security/VMAccessController.java,
and please give feedback on the GNU Classpath mailinglist whether or not
the current AccessController framework is flexible enough.
New in release 0.09 (May 2, 2004)
* Includes updated GNU JAXP version from 2004-02-01.
* Native C code is now -ansi -pedantic (C89) clean and (almost) -Wall clean.
* java.io is now implemented by delegating most tasks directly to java.nio.
* Reworked/Optimized implementations of java.nio.Buffer and subclasses.
* New javax.print, javax.print.attribute[.standard] and javax.print.event
packages and classes.
* java.text attributed iterators support.
* New javax.imageio, javax.imageio.event and javax.imageio.spi packages and
classes.
* GNU Classpath can now load service providers that are described via
META-INF/services/* resources in extension JARs. This is useful for
implementing the various APIs that are supposed to be extensible via
custom plugins. For details, please see the documentation of
gnu.classpath.ServiceFactory.
Application developers are strongly discouraged from calling glibj
internal packages. Instead, they might want invoke the newly implemented
javax.imageio.spi.ServiceRegistry.lookupProviders, which is a standard
method for loading plug-ins.
* New developers wanting to help the GNU Classpath project might want to
review the greatly expanded Hacker Guide included in the doc directory
or online at http://www.gnu.org/software/classpath/docs/hacking.html
Also the FAQ has been expanded. And when working from CVS you can now use
a simple autogen.sh script to get all autotools magic done automagically.
* New configure option --with-glibj which defines how to install the glibj
class files as zip, as flat directory files or both (zip|flat|both)
[default=zip]. When working with multiple runtimes some of which might
not support bootstrap classes in zip files the --with-glibj=both option
is recommended (this does take extra disc space).
* Two big code drops from the libgcj gui branch updating various java.awt
and javax.swing classes.
* Multiple java.net.InetAdress fixes and java.rmi fixes.
* ServerSocket.accept() now restarts listening when system call interrupted.
* Much cleanups to make standard API doc valid XHTML (not completed yet).
* A scan for unused variables and non-static invocation of static methods
turned up a couple of subtle bugs which have now all been fixed.
* The Mauve testsuite has been cleaned up considerable and lots of issues
in the GNU Classpath core class implementation have been fixed.
VM Interface changes:
* java.lang.Class/VMClass interface was changed. The interface now no
longer requires an instance of VMClass for each Class instance. Instead
the field vmdata in Class is now of type Object.
* GNU Classpath now assumes that JNI calls SetXField can modify final
fields. This was previously used silently for System.in/out/err and should
be considered as a feature now.
* A new VMProcess and a sample JNI C implementation are now provided to
make Runtime.exec() work out of the box on some systems. This requires
a small change to VMRuntime.exec() when a runtime wants to use it as the
default java.lang.Process implementation.
* The implementation of most of java.io through java.nio moved serveral
runtime specific I/O methods. Most methods do have a generic default native
C JNI implementation in native/jni/java-nio.
* Runtime support methods for java.io.File have been moved to VMFile which
also comes with a default JNI C implementation.
* To support the new service provider mechanism runtimes must make sure that
extension JARs are made accessible via the default context class loader.
New in release 0.08 (2004/12/03)
* java.util.regexp implementation through gnu.regexp wrappers.
* java.net.URI implementation.
* Working implementation of javax.swing.undo.
* java.awt.geom.CubicCurve2D/QuadCurve2D: Can now solve cubic and quadratic
equations; implementation adapted from the GNU Scientific Library.
* Lots of java.awt and gtk+ peer improvements. Also more Swing work. Start
of EmbeddedWindow support.
* BufferedReader speed improvements.
* Improved useabilty of java.text implementation for several applications.
* ObjectInputStream is much faster and more compatible with other
implementations.
* Fix handling of alias methods, where a method has been deprecated in
favour of a new one with the same funtion but a different name.
(See Deprecated Methods section in the GNU Classpath Hacking Guide.)
* javax.print.attribute.standard added.
* Lots of java.nio, java.net, java.io
* Depend on autoconf 2.59+ and automake 1.7+, GCJ 3.3+, jikes 1.18+.
VM Interface changes:
* Split native methods in java.lang.Runtime into java.lang.VMRuntime.
* Resources are now also loaded/needed through the bootstrap classloader
(gnu.regexp needs MessageBundle included in glibj.zip
Fixed Classpath bugs:
#6095 java.awt.geom.QuadCurve2D.solveQuadratic sometimes gives
wrong results
#7099 EventListenerList.getListenerCount should accept null argument
#7104 EventListenerList.add does not work
#7105 EventListenerList.remove does not work
#7107 DefaultBoundedRangeModel.setValue and friends should not throw
And lots more.
in the process. (More information on tech-pkg.)
Bump PKGREVISION and BUILDLINK_DEPENDS of all packages using libtool and
installing .la files.
Bump PKGREVISION (only) of all packages depending directly on the above
via a buildlink3 include.
New in release 0.07 (2003/30/11)
* Works with libtool 1.5 (and 1.4.3).
* java.awt gtk+ peers now depend on gtk+ 2.2.x and uses pango.
Lots and lots improvements on the peers.
* java.awt.geom.CubicCurve2D, java.awt.geom.QuadCurve2D:
Subdivision and flatness calculation implemented.
* java.awt.geom.FlatteningPathIterator: Working implementation.
* gnu.java.awt.BitwiseXORComposite helper class.
* New rmic compilers (jikes, kjc) support.
* java.text bug fixing and 1.4 updates (Currency).
* Hashtable and HashMap function more similar to other implementations.
* javax.naming and java.beans classloader fixes.
* URL parsing, URLConnection, protocol and (needed) permission fixes.
* More java.nio implementation
(API complete, but implementation not finished yet).
* Lots of java.net code cleanup.
* Improved documentation.
* Numerous bug fixes in almost every package, and lots of updates for
1.4 functionality.
* Fixed Classpath bugs:
#2944 Incorrect synchronization in java.util.logging.ErrorManager
#6075 java.awt.geom.GeneralPath.getCurrentPoint returns wrong results
#6076 java.awt.geom.GeneralPath constructor sometimes hangs
#6089 java.awt.geom.GeneralPath.getPathIterator does not work
[...]
VM Interface changes:
* Thread has been split in a VM-independent Thread class and a VM-dependent
VMThread class.
New in release 0.06 (2003/22/08)
* Update java.awt peers to GTK+2.
* java.awt.GridBagLayout implementation.
* javax.swing.border implementation.
* java.security and java.security.cert updated to 1.4 spec.
* New JNI native target code layer. See native/target/readme.txt.
* --enable-regen-headers configure flag for automatic jni .h file generation.
* Removed workaround for gcj 3.2 and lower, gcj 3.3+ or jikes 1.18+ is now
needed for compiling.
* Lots of improvements and/or new classes for java.awt, java.awt.dnd,
java.awt.font, java.awt.geom, java.awt.image, java.io, java.math, java.net,
java.nio, java.rmi, java.text, java.util, javax.swing, javax.swing.plaf,
javax.swing.text.
VM Interface changes:
* VMClassLoader.loadClass(), the bootstrap classloader called by
Class.forName() and ClassLoader.loadClass(), may now return null when
a class is not found instead of throwing a new ClassNotFoundException.
This is a performance optimization in some cases. This also changes
the Class.forName() reference code.
* Native methods in Class have been moved to VMClass. A few additional
methods are also available in VMClass to provide optional performance
improvements.
* A VM can now supply its own String.intern() strategy through the
VMString class. The supplied VMString reference class implements the
original WeakHashMap strategy.
* Float and Double to/from bits conversion functions can now be supplied by
the VM through VMFloat and VMDouble. Default JNI conversion methods are
supplied.
