Nighty builds for release-1.1 instead of master available?

Our CI testing is currently using Julia nightly builds, as we are relying on a GC extension that was only introduced after 1.0 branched. Now that the release-1.1 branch was created, we’d ideally like to use builds based on that instead (esp. since apparently Julia master recently introduced a change that causes segfaults in our tests; I’ll investigate this separately). Well, of course only until 1.1 is released, then we’ll hopefully be able to switch to the release version.

Now it seems https://julialang.org/downloads/nightlies.html only provides links to nightly builds for master, e.g. https://julialangnightlies-s3.julialang.org/bin/linux/x64/julia-latest-linux64.tar.gz.

My question: Do their also exist “generic” URLs for that “latest build on release-1.1”? If there are no such links: Would it be possible to add them (only if it does not require too much effort; I have no idea how the nightlies are created, and was unable to find any documentation for that, so I have no idea on what’s required to do so).

Looking at https://julialangnightlies-s3.julialang.org there are build paths that contain 1.1 and 1.2. E.g. this is a valid URL: https://julialangnightlies-s3.julialang.org/bin/linux/x64/1.1/julia-b55b85cd99-linux64.tar.gz. Based on this, I tried https://julialangnightlies-s3.julialang.org/bin/linux/x64/1.1/julia-latest-linux64.tar.gz but this does not exist.

For now, I’ll just hard code an older nightly build, and once 1.1 is out, we’ll switch to that. But I imagine the same question may become relevant for us when 1.2 is released; and perhaps others also would like to have nightlies of the release branch?

There are currently no nightly build for anything but the latest master.
