🧩 Analysis chain
🌐 Web query:
Ruby 4.0 release date official announcement 2025
💡 Result:
The official announcement for Ruby 4.0.0 was posted on December 25, 2025. [1]
Sources:
- Ruby-lang.org — "Ruby 4.0.0 Released" (Dec 25, 2025). [1]
🌐 Web query:
ruby/setup-ruby GitHub action Ruby 4.0 support compatibility
💡 Result:
Short answer: As of now (Ruby 4.0 released Dec 25, 2025), ruby/setup-ruby does not yet list Ruby 4.0 as a supported release — the action's supported-versions docs currently stop at the 3.x series (you can use ruby-head as a temporary option). Sources: ruby/setup-ruby README and Ruby 4.0 release announcement. [1][2]
Recommended actions:
- Use ruby/setup-ruby@v1 with ruby-version: 'ruby-head' to test against the latest source until the action adds official 4.0 builds. [1]
- Watch the ruby/setup-ruby repo (or ruby-builder-versions.json) for an update adding 4.0, or open an issue if you need Windows/official builds. [1][2]

Ruby 4.0 is not yet supported by ruby/setup-ruby (v1.276.0) — this workflow will fail.
Ruby 4.0.0 was officially released on December 25, 2025, but the ruby/setup-ruby action (v1.276.0) does not currently provide Ruby 4.0 binaries. The specs and integrations jobs will fail when attempting to run against Ruby 4.0.
Options:
- Use
ruby-version: 'ruby-head'as a temporary workaround until ruby/setup-ruby adds official Ruby 4.0 support - Wait for ruby/setup-ruby to release Ruby 4.0 support and update the action version
- Remove '4.0' from the matrix until the action supports it (your
.ruby-versionfile is already set to 4.0.0)
Also applies to: 30-30
🤖 Prompt for AI Agents
.github/workflows/specs.yml around line 12: the matrix includes ruby '4.0' but
ruby/setup-ruby v1.276.0 does not yet supply Ruby 4.0 binaries so the workflow
will fail; fix by removing '4.0' from the matrix or replace it with
ruby-version: 'ruby-head' as a temporary workaround (or update the action
version once ruby/setup-ruby adds 4.0 support); pick one of these actions and
update the matrix value(s) and/or action version consistently across the
workflow (also adjust other occurrences at lines ~30 if present).
