The SVT-AV1 library was at version 1.8.0 and finally I got it upgraded and checked into GIT.  At first I had to figure out what I was doing wrong in upgrading to 2.1.2, but by the time I figured that out, they released a new version on Aug. 24 (2.2.1).  Encoding seems to be somewhat faster.

Previously on Aug. 16, GIT checkin was for the latest version of dcraw dated 2018, giflib 5.2.2, and flac 1.4.3 which may not have been recent updates but were the latest available -- might as well use the latest even if no significant changes.

I am still checking to make sure we have the latest libraries in use for the other ones so do not plan on creating a release on Aug. 31 -- especially since SVT-AV1 version is so new and I only did a cursory test.  Hopefully, Terje can check using the SUSE package at:   https://github.com/einhander/cin-gg-packages/releases/ when it has been newly built.
