@ayrat555 thank you, I see most of the CI is failing, going to take a look over the weekend.

@tzumby it seems the new version doesn't support old otps

I see, just checked the rustler CIs and I see they support OTP 24 and on, I think that's good enough. I'll update the targets here and bump the minimum requirements a little. Hopefully this works with Elixir 15 as well

Hey @ayrat555, I pushed an update to use newer versions for Erlang and Elixir, but I think you need to pull those and update your branch, tried re-running, but duh, it runs the same github actions workflow :)
