Elixir v1.17.0-rc.0 released

[Eiji]

Not sure if that was typo and they want to say 25 as this would also be supported, see:
Between Elixir and Erlang/OTP section of Compatibility and deprecations documentation.

Recommend != required, so maybe there are some significant performance changes in OTP 26 or other important changes, but anyway you should be fine until Erlang/OTP 18 stable release + next Elixir version after it.

Latest Elixir fully supports previous 3 Erlang stable releases and sometimes one next in patch release which was not possible in Elixir version 1.16.3, see:

Erlang guarantees byte code compatibility across 3 versions. So we can’t provide precompiled Rebar and Hex that works from 24 all the way up to 27 (sometimes we can, but not this time). The fix would be to precompile several versions of them, we want to do for future releases.

Seeing recent release dates we can estimate that Erlang/OTP 28 would be released around the middle of May 2025, so the earlier version of Elixir which would drop support for 25 would be 1.19 which stable release would most probably be around June 2025, so you should still have at least a year of support.
