New Mix format documentation explains how plugins handle .ex and .exs files, addressing a long-standing point of confusion.
The Elixir docs now include a section on Mix Format plugins clarifying the current behavior for .ex/.exs file types [1]. The addition stems from a discussion in PR #15742 and aims to shorten the path to understanding for developers who, like the author, "had read the docs thoroughly beforehand" but still found the behavior unintuitive [1]. The change ships in a single commit [2]. Meanwhile, Ecto updated its CI workflow, bumping actions/checkout to v7 and actions/cache to v6 [3]. The cache update requires Actions Runner 2.327.1 or newer on self-hosted runners, so teams running Ecto CI on self-hosted infrastructure should verify runner versions [3]. The change is scoped to .github/workflows/ci.yml only, with cache inputs unchanged [3].
