There's an open stardew beta for 1.6.9 that you can opt into with a changelog. It's so that people can test out the update and report any issuesHow do you know this? Are you secretly an insider and have news you haven’t been sharing with us all along here?. No I realize it’s likely been posted somewhere out there on some Stardew gossip column somewhere, though I haven’t seen a thing.
I believe there is a link somewhere on the main stardew valley website with a link tucked away on how to join. It's public but they don't want it spread everywhere on big platforms like twitter (as they want it pretty contained without a million duplicate bug reports coming in)
It's nice to look at just the changelog alone to see what's being added
