UE4.16 is out and I’ve checked the latest version of ATBTT as compatible with the new version, so it should now be available through the launcher. There are no differences between this version and the 4.15 version of the toolkit, so if you are working with ATBTT in 4.15 and want to continue in 4.16 simply open a copy of your 4.15 project in UE4.16. The next feature update is still in the works.
