Libtiff 4.0.0beta4 is now released. Please read about it at http://www.remotesensing.org/libtiff/v4.0.0.html.
Source packages are available at ftp://ftp.remotesensing.org/pub/libtiff and will soon be available at mirror sites.
Libtiff 4.0.0beta4 is produced from the default branch in the libtiff CVS repository. Its focus is to introduce major new features such as support for BigTIFF. Libtiff 4.0.0 is NOT ABI compatible with 3.X.X releases. In particular, it uses a 64-bit toff_t and 64-bit tmsize_t.
Existing applications are likely to work with libtiff 4.0.0 with a simple re-compile as long as they took care to use libtiff typedefs and avoid sloppy casting. The most common problem is with code which assumes that a returned file offset or size can be stored in a 32-bit type. Users of libtiff are encouraged to test their applications with libtiff 4.0.0beta4 and make any required changes so that their application will work with it.
There is reason to believe that libtiff 4.0.0beta4 is as reliable as the stable releases.
Please report any bugs according to the procedure documented at http://www.remotesensing.org/libtiff/bugs.html.
