Where to find the newest Beta's?

Hello Guys - where to download the newest beta’s? the one on Git seems to stop at Beta 2 - and JFrog Bintray i can’t download from directly?

https://github.com/openhab/openhab-distro/releases/tag/2.0.0.b4 says “The binaries are available on Bintray” and links to https://bintray.com/openhab/mvn/openhab-distro. If you scroll down, you will find the zips there.
