Asset is working on 2018.2.11f which is pretty much latest official non-beta release. It has not been tested on 2018.3. Asset is live and the last update was in June which is true. Current version is 1.7.2 on which is a LTS release with so far no bugs reported (see TODO) and that is why there was no update in the mean time. I am of course working on other projects too and when there will be a few things on the TODO list I will post another update. You can check out the changelog at the bottom of TODO file and you will se that over the few months after the release I have worked almost exclusively on the package making it as bug-free as possible and improving different things. If you got something reasonable that you want to see inside the package do tell.
