GitHub Actions workflow lockfiles in public preview

GitHub published a changelog entry titled "GitHub Actions workflow lockfiles in public preview" on October 14, 2026. The post appears on the GitHub Changelog under the URL https://github.blog/changelog/2026-10-14-github-actions-workflow-lockfiles-in-public-preview, and its publication timestamp is listed as 2026-10-14T13:49:15.000Z. The title states that workflow lockfiles for GitHub Actions are in public preview. The supplied source text consists of the changelog headline and embedded typography styling rules, such as heading font-size and margin declarations. It does not include the body copy of the announcement, so no information is available about how lockfiles are created, which workflow syntax or file paths they apply to, whether they are opt-in, or how they interact with existing Actions features. Because the excerpt does not describe those mechanics, this digest does not characterize them. What the source does establish is the status change itself: workflow lockfiles are described as being in public preview, meaning the capability is presented as available in a preview stage rather than as a finished, generally available release. No version numbers, pricing, limits, or benchmark figures appear in the source text, and none are reported here.
