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:

## Software configuration changes

- configure now recognizes IRIX 6.x systems

- configure now uses `ENVOPTS` when searching for an ANSI C compiler; this fixes a problem configuring the software under HP/UX with the native C compiler

- configure now correctly recognizes memory-mapped files are supported under AIX

## Library changes

- `make install` now properly installs the include files

- some portability fixes from Bjorn Brox

- the G3/G4 codec now warns about decoded rows that are longer than the image/tile width

- changes from Frank Cringle to make the library work with the gcc-specific bounds checking software

- miscellaneous fixes to `TIFFPrintDirectory()`

- bug fix to correct a problem where `TIFFWriteRawStrip()` could not be used to automatically grow an image's length

## Tools changes

- fixes from Frank Cringle to update fax2tiff

- portability fixes to tiff2bw and tiffcmp

- tiffdump now uses the byte swapping routines in the library
