Plan on Godot 4.0 compatibility?

neoe

I am new to Godot from 4.0 alpha because I like vulkan. But I noticed that the demos for 3.x simply not work on 4.0 currently. So the old users will suffer from upgrade to 4.0 if their old works cannot be imported.

I know this is a open source project but I still want to ask what's the plan of the official team, which mostly will affect the result of Godot 4.0's backwards compatibility. Thanks.

3.x projects will have to be modified to work on 4.0. Some of the changes will be automated, other changes will have to be made manually.

I forward the answer from Rémi Verschelde at other place

yes, demos will be ported to Godot 4.0 at some point. Godot 4.0 is still in alpha and thus unstable and changing daily, so we haven't ported demos yet because they would have had to be re-ported several times to take into account the past two years of development changes.

So I feel I am free to use either 3.x or 4.0 alpha at this point.

Well you could port them yourself, but it might be a lot of work. I ported one of my demos, which didn't even have a lot of code, and it took 3 days. For a full on game it could take several weeks or up to a month. But I imagine a demo could be ported in about a week. But it might be confusing, and I would recommend just starting a new project yourself in Godot 4.0.
