Libtiff 4.0.10 is now available.  Read about this release at 
http://www.simplesystems.org/libtiff/v4.0.10.html.

The release files may be downloaded from 
https://download.osgeo.org/libtiff/.  The ftp site appears to be 
currently down.

It has been a year since the previous release.  This is the first 
release made from the Git repository at 
https://gitlab.com/libtiff/libtiff using a collaborative process.

Since the previous release, a number of security issues have been 
fixed, and some significant new features have been added.

This release adds support for Zstd and WebP compression algorithms. 
In their own way, each of these compression algorithms is highly 
complimentary to TIFF.

Zstd provides improved compression and decompression speed vs zlib's 
Deflate as well as a broader range of compression ratios.  Zstd is 
developed by Facebook and the implementation continues to be improved.

WebP is optimized for small/medium 8-bit images while offering 
improved compression performance vs traditional JPEG.  WebP works well 
in strips or tiles to compress large images down to very small files, 
while preserving a good looking image.  WebP is developed by Google, 
and its implementation continues to be improved.

Due to Adobe's TIFF tag registration interface going off-line, we have 
had to assign our own tags for Zstd and WebP.
