Unity have strict requirements for uploading to the store and sometimes they do not accept our update (leaving the store listing on the old version). We are very close to releasing 2.02.07, this will be the next candidate we submit to Unity for verification, the process usually takes around two weeks, if accepted it will go live on the asset store. You can however always get the latest version from our website.
Regarding moving the FMOD folder you are quite right, my comments were regarding moving it anywhere under the assets directory, i.e. Assets/FMOD or Assets/3rd_party/FMOD. We do not currently support moving it to the packages directory, this is largely because we use the old asset package method, not the new package method. Honestly we’d be keen to switch to the new method, but then we would not be allowed to submit to the asset store and we’re not keen on maintaining two different install methods.
I’ll create an internal task to consider the changes you suggest though, this is all work that would be required if Unity ever permit the new style packages into the store. Any work that is done ahead of that goal should make your integration process less involved.
