libtiff for Debian
+----------------+

This version of libtiff is installed with a different shared library
soname from the upstream version.  This is because an accidental
change to the library's ABI was introduced somewhere between 3.5.7 and
3.6.1.  There are no source-level incompatibilities between 3.5.7 and
the current version, so any application that worked with 3.5.7 should
work fine when recompiled with the libtiff4 packages.

libtiff version 3.7.1 introduced an experimental and minimal C++
interface.  To use it, you must link against -ltiffxx.

libtiff version 3.8.0 upstream introduced another binary
incompatibility, but it was fixed within a few days of 3.8.0's
release, and the binary incompatible never appeared in any debian
version of the tiff packages.

libtiff version 3.9.0 is binary compatible with all versions going
back to 3.6.1, even though this was not true of 3.9.0beta.

Example tiff files are available:

 ftp://ftp.remotesensing.org/pub/libtiff/pics-<version>.tar.gz

These files may be useful for people testing software to make sure it
can work with a wide variety of tiff files.
