Hey @gadrian, sorry I'm just now seeing this. But many of us are still waiting to see a stable version of 19.11 (19.10 also just updated to v19.11 due to that version trying to process blocks that were too large). So now we have the stable version 19.6 and the new version 19.11. Anyways, as soon as I hear an update, I'll definitely pass that info along and I'll be updating my witness at that time. But I know many of us are looking forward to the updates that it'll bring to the blockchain :)
PS: Still no word on when HF20 will be released either. But I'm sure we're getting closer by the day. One thing I can say for sure is that the Steem development team is working around the clock on this blockchain.
Thanks Brandon! Yeah I noticed 0.19,10 updated to 0.19.11 too, but after I commented here.
Maybe they are working hard on HF20 and don't want to allocate resources for creating an intermediary stable 0.19.11. Their initial ETA was the first month of fall if I remember correctly, so would be at most one month away.
