What is the current behavior?

PR #249 (dependabot) updated astral-sh/setup-uv commit SHA from v7.1.6 to v7.2.1 but left inline comments unchanged, causing version mismatch.

Both workflow files reference SHA 803947b9bd8e9f986429fa0c5a41c367cd732b41 with stale comment v7.1.6 released on 13-12-2025.

What is the new behavior?

• Updated inline comments in .github/workflows/linting.yaml and .github/workflows/testing.yaml
• Comments now correctly state v7.2.1 released on 30-01-2026 matching the actual commit SHA
• SHA and version metadata now aligned across both workflow files

Does this introduce a breaking change?

• Yes
• No

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/repos/astral-sh/setup-uv/git/ref/tags/v7.2.1
  • Triggering command: /usr/bin/curl curl -s REDACTED (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
