Hi, I have a small question, where is the v1.2 Release Note?
I see the release page says https://kyuubi.apache.org/releases.html has a new release. But there is no v1.2 Release Note.
Thanks for reply.

hi @zhenjiaguo , the v1.2 version is released before we join Apache so it is legacy. Please see the latest version v1.3.1-incubating.

Hope it can help you.
