+ has smaller state tables
+<LI>Niles Ritter's client tag extension hooks were added
+<LI>a new routine <TT>TIFFCurrentDirOffset</TT> was added for
+ applications that want to find out the file offset of a TIFF directory

+ for images with certain esoteric configurations
+<LI>a potential memory leak (very unlikely) was plugged
+<LI>the <TT>TIFFReadRGBAImage</TT> support was completely rewritten
+ and new, more flexible support was added for reading images into

+<LI>YCbCr to RGB conversion done in the <TT>TIFFReadRGBAImage</TT> support
+ was optimized
+<LI>a bug in JPEG support calculation of strip size was corrected
+<LI>the LZW decoder was changed to initialize the code table to zero
+ to lessen potential problems that arise when invalid data is decoded
+<LI><B>tiffcomp.h</B> is now aware of OS/2
+<LI>some function prototypes in <B>tiffio.h</B> and <B>tiffiop.h</B>
