TIFF CHANGE INFORMATION
This document describes the changes made to the software between the
previous and current versions (see above).
If you don't find something listed here, then it was not done in this
timeframe, or it was not considered important enough to be mentioned.
The following information is located here:
MAJOR CHANGES:
- LZW compression enabled by default. You don't need the separate
compression kit anymore.

into TIFFs.
- The first attempt to implement a test suite.
CHANGES IN THE SOFTWARE CONFIGURATION:
- Many portability fixes in the new autotooled build suite.
CHANGES IN LIBTIFF:
- libtiff/{tif_luv.c, tif_next.c, tif_thunder.c}: Several buffer
overruns fixed, as noted by Chris Evans.
- BSD data types (u_char, u_short, u_int, u_long) is no longer
used internally in the libtiff. Should result in simpler configuration
and better portability.

specification. Reference libtiff bug tracking system to submit
private tag additions.

SamplesPerPixel size when the tag count is greater than number of
samples as per bug
