For now -- unfortunately no. We used bintray for our dev builds for very long time, but unfortunately it will be closed soon. So we migrated to our internal infrastructure and trying to figure out what to do next, because we are not ready to support stable infrastructure for repo with dev builds.
We still able to share some builds from time to time for example to check that fix helped.
Could you please share your use-case? How you used our dev builds? and why Mx and RC builds is not enough?
