Manifest 5 - How long do we have to convert?

Photoshop UXP Plugin API
1

Question for Adobe…
How long is Manifest 4 going to be supported? I have 10 plugins, all using manifest 4 (API 2). I’m just wanting to know how long I have to get them converted to manifest 5 before Photoshop doesn’t support manifest 4 anymore.

So will this happen in CC 2023 in 3 months? Or do we have at least until CC 2024?

Also wondering how long API-1 is being supported. I still have plugins running AP1-1 apparently w/o problems.
