If you read the post, there’s a link to an existing discourse thread: Trying out Ubuntu 23.04 on x86-64-v3 rebuild for yourself
Note this comment:
I should have expected that given we didn’t say what our plans are for the future people would start to fill in the gaps a bit. But the reason we didn’t say anything about that is mostly that we haven’t decided where we’re going with this. We are literally just running some investigations!
What I can say with certainty is:
- Nothing is going to change wrt the amd64 baseline in 24.04.
- We are very aware of the issue of users who have hardware that can’t run v3 or even v2! Hopefully we can do something that gets the best of both worlds but like I said, no concrete plans yet.
