• Separate history per runtime. Official reporters record the language runtime, such as node 22.10.0 or cpython 3.12.7. When a project runs the same tests on several runtimes side by side, such as a Node 20/22/24 matrix, each runtime now gets its own history, labeled with the coarsest version that tells them apart (node 22). Without a matrix, runtime upgrades stay in a single history. See Configuring Environments.

• Tests page guide. A Guide button next to the Tests page title highlights the main parts of the page: the branch and environment selectors, the test health calendar, search, the status cards, and the tests table. Hovering or clicking a highlighted part explains what it shows.

• Column help in the tests table. The Duration, Duration Trend, Flip Rate, and Fail Rate columns now have help icons that explain how each value is computed. The History column’s help explains what a bar’s color and height mean for the selected history period.

• Runs of dangling commits are deleted after 14 days. Runs of commits that no branch or pull request points at, such as commits replaced by a force-push, are now deleted 14 days after upload, even when the project’s data retention is longer. Most of these runs test pull request merge commits that a later push replaced. See Data Retention.
