GitHub announced a generally available Copilot code review update on September 18, 2026, adding a clearer view of findings across review rounds. The notable QA detail: reviewers can distinguish issues introduced by a new commit from issues discovered later in existing changes.
What changed
The overview now shows the current assessment, review effort level and findings. Open issues can carry a new label; a separate group tracks issues resolved since the previous review. A previously missed section contains findings discovered in existing changes during a later pass. GitHub says those details appear in the overview rather than elsewhere on the pull request.
Comments also gain short titles. Copilot honors replies asking it to keep an issue open, and can use Incorrect or Won't Fix resolution reasons. Eligible complete batches of accepted suggestions receive generated commit titles and optional descriptions. See the official September 18 announcement.
Why this matters for QA engineers
QATechTools analysis: discovery time and defect introduction time are different. A warning that appears only on the second review should not automatically be counted as a regression caused by the latest commit. This distinction can improve triage discussions and defect reporting.
For a pull request that changes a flaky test or assertion, inspect the overview as well as inline comments. Reproduce each relevant finding against the current commit, then attach the failing test or execution evidence to the triage record. Treat Copilot's resolution status as a review signal; use test results and human judgment to decide whether the defect is closed.
A useful team check this week: take one PR through two review rounds and record which findings are new, previously missed or resolved. Confirm the reviewer notices overview-only findings, and inspect generated commit messages before accepting them. These are QA recommendations, not additional GitHub product claims.
This follows the earlier Copilot auto-resolution update; the new focus is visibility across successive reviews.
