Hi. I found that latest NavMeshComponents shows compiler warning due to deprecated API in 2020.1.0b5. There is no 2020.1 branch on its github repository.
Please make NavMeshComponents be package and automatically update it by Unity’s major version change, like other packages (ex, timeline, textmeshpro and so on). Or merge it to engine’s navmesh feature. Why it is separated? I think there is no benefit. (Does anyone use NavMesh feature only without NavMeshComponents?)
Currently, for every Unity update, you should delete exiting NavMeshComponents and download new branch of it and extract to project folder. It is very annoying.
