The given patch will add IPv6 support to nzbget. Both the internal client-server connection and the external connections to an IPv6 newsserver have been successfully tested. For testing, you can use newszilla6.xs4all.nl, which allows 3 simultaneous connections and is open for everyone with an IPv6 connection. Reproducible: Always Actual Results: No IPv6 support Expected Results: IPv6 connection

Did you submit the upstream? (BTW, 0.3.0 was released last November).
Created attachment 141877 [details, diff] Better patch
Yes, I submitted it upstream and I saw 0.3.0 is out. The patch may also be applicable to 0.3.0, as it uses a similar Connection class. I didn't try 0.3.0.
Created attachment 142397 [details, diff] Better patch Had to remove one more line that wasn't used to make it work.
Created attachment 142402 [details] ebuild that uses the ipv6 patch Added one epatch line to nzbget-0.2.3-r1.ebuild
0.2.3 is no longer in the tree, and such feature requests belong more to the uptsream bug tracker than to a distribution.
See Bug #231740 for a patch for the current version of nzbget.
