Recently the builds of some FOSS Elixir libraries that I wrote started erroring on older Elixir versions. See for instance [Qqwy/elixir-sequences] with errors as follows:
It seems that older OTP<->Elixir-combinations that existed within Travis have been removed somewhere between the past three months, and the build process breaks on them.
This breakage occured because of a change on the Travis side: rerunning the build for the unaltered code that was last built three months ago will now suddenly make it fail.
What has changed? I have roughly ten-twenty open source projects being hit by this, so I would be really happy with any and all solutions. Thanks!
