I would separate two topics: the JC version that CfD references and the Kotlin version that CfD 1.0 uses.
From API perspective CfD 1.0 is much close to JC 1.1-beta that it references, than to JC 1.0. However as Compose is backward-compatible, I wouldn’t expect much issues due to it.
From Kotlin perspective - there is a plan to issue Compose Multiplatform 1.0.1 working with 1.6.10 and referencing latest available JC at that moment. However, most probably there will be no JC 1.1 at that moment.
From the API perspective, if you want to be on the safest side, you should wait JC 1.1 and Compose Multiplatform stable release that will reference it.
