2. [2] 2026-09-25 Changes to query results in the GitHub Actions API and UI

   Queries for workflow runs in the GitHub Actions API and UI now return a less precise but more accurate count of records when you search by workflow, event, status, branch, or actor. We will continue to return paginated results of up to 1,000 items. However, if the number of found records exceeds 2,500, we will report “2,500+” instead of attempting…

3. [3] 2026-09-25 GitHub Copilot app for Beginners: How to build custom workflows with canvases

   Most tools give you a fixed set of screens and ask you to fit your work into them. But what if you could start with the workflow you want instead and have the interface take shape around it? That’s the idea behind canvases in the GitHub Copilot app. A canvas, also called a canvas extension, is a customizable interface that…

7. [7] 2026-09-25 Improving site performance by shipping more CSS

   The Primer Design System powers many of the experiences you see on GitHub today. From buttons to banners to breadcrumbs, these foundational components are required to be accessible, flexible, and performant across a wide variety of scenarios. Back in 2023,… The original CSS migration was a little bit more nuanced than we led on: in addition to migrating the components to CSS modules, feature flagging to test in production and slowly rolling them out, we also created “wrapper” components in…

10. [10] 2026-09-24 Expired GitHub Actions artifacts no longer shown in UI and API

    Expired artifacts are no longer displayed in the GitHub Actions run summary or returned by the REST API. Previously, an expired artifact remained visible with an “Expired” pill, even though the underlying files had already been deleted from storage. That leftover pill left some users unsure whether they were still being billed for storing artifacts that no longer existed. To…
