Hi,
I’d like to release an asset to the asset store. Which Unity version should i use for that?
If i use the latest one, people who haven’t upgraded won’t be able to use it.
What is the common approach for this? Note that my asset is only code, and doesn’t use any new (e.g: Unity 5.x) APIs in it.
Hi,
Look at the Unity version usage thread.
Consider submitting with Unity 4.5. This will cover about 95% of all Unity users. You’ll still want to install and test on 4.5, 4.6, and 5.0 before submitting, since the APIs changed fairly significantly with each of these, and you’ll want to make sure there are no support issues with them.
And good luck!
Thanks, i will do that 
BTW - why isn’t it possible to submit the package from any version and select which is the minimal compatible version? seems like it should be a lot easier than install a different version just to submit it from.
Selecting a version yourself is very error-prone; there’s no real way to know for sure without actually running that version of the editor. Also what you’re uploading are Unitypackages, which aren’t necessarily compatible with older versions.
By the way, if you’re uploading with 4.x, you also need to also upload again with 5.x.
