@section Noteworthy changes in version @samp{0.5.0}

@itemize @bullet

@item
NSBrowser and NSBrowserCell have been implemented.  There is one odd
display artifact; lists which are smaller than the browser column area
have the list justified to the bottom of the column versus the top of
the column.  This is actually an issue with NSMatrix and will be
remedied when flip views are implemented.

@item
Two important optimizations that speed up the displaying of views and flushing
of windows have been implemented. Only the views that need display and those
that produce visible effects on the screen receive the -drawRect: message.
Flushing of windows occurs only in rectangles that get displayed not in the
whole window.

@item
Rotation and scaling of views have been finally implemented. The code
requires backend support for changing the state of the graphics context
accordingly.

@item
NSScrollView and NSClipView have been implemented. The current implemented
behavior is to call the document view to display the exposed region. Copying on
scroll will be supported soon, at least on Solaris DPS, where it seems the
Postscript language has provisions for copying drawn regions of screen.
Hopefully DGS will also have this facility by the end of the year.

@item
NSScroller has been completely reworked to gain speed by using timer events.

@item
NSSlider has been implemented. Thanks to Frank Knobloch for supporting this
and the NSScrollView implementation.

@item
NSBox has been implemented.

@item
The library has been ported to work under Solaris with the native DPS and the
NeXT/Apple's Portable Distributed Objects (PDO) environment.

@item
The library has been integrated with the makefile package so we now benefit
from all of the features the makefile package gives us, especially the
possibility to build shared libraries on various systems and having different
types (debug and profile) of the library compiled at the same time.

@item
NSCell is able to continuosly send the action to the target while the user is
tracking the mouse.

@item
Several cleanups and as usual, many bug fixes.

@section Noteworthy changes in version @samp{0.3.0}

@itemize @bullet

@item
Completely reworked the menu class. The NSMenu class is now inherited from
NSObject and using the new implementation menus have been implemented for the
XDPS backend (they have the look and feel of the NeXTStep menus!).

@item
NSRunLoop has been integrated with NSApplication. Using this capability time
events have been implemented to NSEvent class. These events allow several
improvements in the interaction between user and the graphic interface.

@item
NSMatrix has been reworked, it is now conforming to the OpenStep specification
and it knows all the selection modes. It uses time events to enhance the
drawing speed during mouse drags.

@item
The initial implementation of NSForm has been made although it has not been
tested yet.

@item
NSPrinter has been implemented though it was not throughly tested; thanks to
Simon Frankau.

@item
Configure script has been changed to detect the underlaying Foundation library.
The currently supported libraries are gnustep-base and libFoundation.

@item
Several cleanups have been made in a lot of classes: the retain/release policy
has been fixed, the cell classes correctly implement the NSCopying protocol
and many others.

@section Noteworthy changes in version @samp{0.2.0}

@itemize @bullet

@item
Additional NSImage and NSImageRep class work.  Incorporated common
images for use with controls that were designed by Andrew Lindesay.

@item
Fill out implementation of NSColorWell class.

@item
Fill out implementation of NSColorList class.

@item
Cleaned up the header files and added missing headers, methods,
categories, and protocols; thanks to Simon Frankau for much of this
work.  Major reorganization of header files.  Types and constants were
moved in the files they belong.  Each header file includes only the
headers it really needs.  Use @samp{@@class} to forward class definitions
instead of including the corresponding class file.

@item
Completely reworked the NSFont and NSFontManager classes so that
NSUserDefaults is used for getting defaults and list of known fonts are
maintained.

@item
Initial implementation of NSCursor class.

@item
Almost complete implementation of NSButton and NSButtonCell class.
Buttons can now display images and/or text, handles all of the OpenStep
button types and styles.

@item
Fill out implementation of NSScroller class.

@item
Put in underlying support for optimizing drawing; flushing of windows,
backing store, and only display when needed.

@item
Many bug fixes and minor enhancements.

@section Noteworthy changes in version @samp{0.1.1}

@itemize @bullet

@item
Almost complete implementation of the PXKMenu and PXKMenuCell classes.

@item
Fill out implementation of NSFont and NSFontManager.

@item
Fill out implementation of NSColor including color spaces other than
RGB.  Now maintains the common colors as global variables.

@item
Integration with the Display Ghostscript System.  This is mainly related
to using the header files in the DPSclient library for defining the
PostScript operator functions.

@item
Initial documentation set.

@item
Initial implementation of NSImage, NSImageRep, and NSImageRep subclass
classes based upon work by Adam Fedor.

@item
Now requires the TIFF library for reading, writing, and manipulating
tiff files and images.

@end itemize

@section Noteworthy changes in version @samp{0.1.0}

@itemize @bullet

@item
Integration of the GNUstep X/DPS GUI Backend.  This has finally
produced a set of core code with can display on X/Windows.
Much of the X/Windows code has been written by Pascal Forget 
@email{pascal@@wsc.com} and integration efforts have been lead by Scott
Christley @email{scottc@@net-community.com}.

@item
Some major directory reorganization for the new naming guidelines.
Headers previously in AppKit and DPSClient directories have been moved
to gnustep/gui and gnustep/dps directores and symbol links are
created for the AppKit and DPSClient directories.  This should allow
both GNUstep and other OpenStep implementations to reside on the
same machine without conflicts.
