How to set assetbundle version?

WWW.LoadFromCacheOrDownload needs a version parameter, but BuildPipeline.BuildStreamedSceneAssetBundle and BuildPipeline.BuildAssetBundle do not have any parameter to specify version.
What does version refer to?

Answered your own question :stuck_out_tongue:

When you LoadFromCacheOrDownload it assigns that version number do the Bundle. Next time you try and DL, if the version matches, it’ll just grab it from cache.

Thx!
