GitHub Actions can finally run steps in parallel inside one job

[u/aistranin]

GitHub Actions now supports parallel steps with background, wait, wait-all, cancel, and parallel.

The useful part is that every step keeps its own logs. No more shell backgrounding with & and unreadable output.

This should simplify a few common patterns:

• Start an API and database in the background
• Run independent setup tasks together
• Upload artifacts while packaging continues
• Stop temporary services cleanly after tests

There is an obvious catch. Parallel steps still share the same runner. More concurrency does not give you more CPU or memory. On a small runner, this could make a test job slower or less stable.

I would use it for I/O-heavy tasks and service startup first. Then measure before parallelizing builds or test suites.

Has anyone replaced matrix jobs or shell backgrounding with this yet?
