That's a fairly on-topic question :)
Currently I'm running my main node on 0.19.5 and have a backup standing by with 0.19.10. There has been at least one issue that has come up with past post editing and I think it's better to start with a trickle than to open the floodgates all at once.
Thanks for responding, @pfunk.
Glad to hear you're moving in that direction. FYI, my primary motivation for trying to shepherd this forward is that I have been lobbying for years now for one particular change. As a content creator, I need the ability to edit all my posts, not just recent ones. This is especially important to me because of my approach to developing and maintaining a Steemit Library of my work as an on-chain entity.
In any case, a lot of the pressure was taken off me this week by witness @timcliff's proactive publishing of a "preview" condenser that gives me early access to that ability.
Thanks again for your reply.
