New Features for Open Inventor 2.1 are:

    New and Updated_Documentation
	Inventor 2.1 includes a new book, the Open Inventor 2.1 Porting
	and Performance Tips.
    New File Version
	The file version has been updated to 2.1
    DSO Directories and Versions
	To avoid problems with incompatible code, the places Inventor
	searches for Dynamic Shared Objects (DSO) implementing new
	nodes has been changed.  For details please read the release
	notes of Inventor 2.1.
    VRML File Supported
	The SoDB read methods now also read files with the VRML 1.0
	header.
    User-Defined File Headers
	The SoDB class now includes methods for registering your own
	file headers.
    SoOutput::setFloatPrecision()
	You can now specify a precision to use when writing out
	floating point numbers.
    SoDB::readAll() Supports Paths
	The SoDB::readAll() method now supports reading objects of type
	SoNode or SoPath.
    New Nodes
	Inventor 2.1 now supports the following new nodes. For deatils,
	please read the release notes of Inventor 2.1.

	SoVertexProperty
	SoLOD
	SoLocateHighlight
	SoWWWAnchor
	SoWWWInline
	SoAsciiText
	SoFontStyle

    New Fields
	Inventor 2.1 now supports the following new fields. For
	details, please read the release notes of Inventor 2.1
	specifically regarding: fields and isA.
    SoGLRenderAction Render Abort Callback Changes
	The render abort callback of the SoGLRenderAction no longer
	returns a simple Boolean value. Instead, it returns an abort
	code that is one of:  CONTINUE, ABORT, PRUNE, or DELAY.
	CONTINUE is the same as returning FALSE in previous releases,
	and ABORT is the same as TRUE.
    New Manipulator for 3D Transformations
	A new manipulator, SoTransformerManip, has been added to the
	set of Inventor manipulators.
    OpenGL Texture Object Extension
	Open Inventor 2.1 makes use of the OpenGL extension for texture
	objects.  Consequently, on systems where this OpenGL extension
	is available, you will see improved texture mapping
	performance.
    Additional Texture File Formats
	The Inventor 2.1 SoTexture2 node now supports GIF and JPEG
	image files. The JPEG files are read using the fifth public
	release of the Independent JPEG's group free JPEG software.
    Picking vs. Viewing
	When in picking mode in any of the viewers, you can now
	temporarily switch to viewing mode by pressing the key. Note
	also that the manipulators now use the key as the modifier key,
	instead of the key.
    Disabling the Viewer Cursor
	The application can now set the cursor in the viewer windows
	directly, if it first disables the viewer cursor using
	SoXtViewer::setCursorEnabled().
    Targets for Copy and Paste
	The SoXtClipboard supports the following new data targets for
	copy and paste:

	INVENTOR_2_1
	INVENTOR_2_1_FILE
	VRML_1_0
	VRML_1_0_FILE
	INVENTOR_2_0
	INVENTOR_2_0_FILE

	The targets INVENTOR and INVENTOR_FILE are supported for
	backwards compatibility. They are equivalent to INVENTOR_2_0
	and INVENTOR_2_0_FILE.
    File Downgrade Utility
	A new utility program, /usr/sbin/ivdowngrade, takes an Inventor
	file and converts it to Inventor version 2.0 or 1.0.
    Program for Converting Files to Use SoVertexProperty
	This release includes sample source code for a utility program,
	ivAddVP, to help convert Inventor files into 2.1 files that use
	the vertexProperty field for the vertex- based shapes.
    Program for Optimizing Scene Graphs
	This release includes a new utility program, /usr/sbin/ivfix
	that restructures Inventor scene graphs for improved rendering
	performance. (The ivquicken utility program is no longer
	supported.) Note that ivfix makes significant changes to the
	structure of your scene graph.
    Program for Analyzing Rendering Performance
	This release includes sample source code for a utility program,
	ivperf, for analyzing rendering performance. See Open Inventor
	2.1 Porting and Peformance Tips for more information on using
	ivperf
