All, In ORC-674 <https://github.com/apache/orc/pull/553>, I commented that some of the recent changes in trunk have broken older versions of cmake. Rather than figure out how to fix it, I propose that we drop both Debian 8 and Ubuntu 14 from our supported Linux versions. (They are both EOLed by their vendors.) I've also added the minor change to get ORC building on Ubuntu 20, so we can add that to the supported versions.
Any concerns? .. Owen
