@demotomohiro The Nim nightlies repo has been updated so that the releases are named with a new scheme: `<BRANCH>-<DATE>-<HASH>`.
New releases with this new naming scheme will be out in about 1-2 hours. Then you can get the JSON data [https://api.github.com/repos/nim-lang/nightlies/releases](https://api.github.com/repos/nim-lang/nightlies/releases), and inspect just the first two elements. The element which has the `name` field beginning with `devel-` will contain the latest nightly build from HEAD (`devel` branch). Let me know how this goes.
