CASSANDRA-16212 is about to be committed to trunk, upgrading JNA from 4.2.2 to 5.6.0.
This will mean that Cassandra 4.0 requires a glibc-2.7 or greater system. Consequences of this will be the following distributions will no longer be supported - Centos 5 (and earlier), (EOL was 2017-03-31), - Debian 4 Etch (and earlier), (EOL was 2010-02-15) - Ubuntu 7.10 Gutsy Gibbon (and earlier), (EOL was 2009-04-18) Given the EOL dates to those distributions I don't see this being a problem, but am raising it for visibility just in case. Speak up if there's objections. It will be listed in NEWS.txt regards, Mick
