Honestly lost my hope that NewsBlur would support SNI anytime soon after the recent (way late) announcement from the Ubuntu folks that they wouldn’t backport Python 2.7.9 to Ubuntu 14.04 LTS (and others). But fortunately I was wrong!
That announcement was what made me perform the upgrade myself. They’ve been saying they were going to support it natively for almost two years now. Thank goodness they said it wouldn’t happen, otherwise we’d still be waiting!
The other good news is that due to that deep upgrade, Unicode support is now richer and more reliable. I had a few feeds that were in far different languages than English and it was very helpful to have those to test with.
