Starting January 30th, 2025, GitHub Actions customers will no longer be able to use v3 of actions/upload-artifact or actions/download-artifact. Customers should update workflows to begin using v4 of the artifact actions as soon as possible. While v4 of the artifact actions improves upload and download speeds by up to 98% and includes several new features, there are key differences from previous versions that may require updates to your workflows. Please see the documentation in the project repositories for guidance on how to migrate your workflows.
The deprecation of v3 will be similar to the previously announced v1 and v2 deprecation plans, which is scheduled to take place on June 30, 2024. Version tags will not be removed from the project repositories, however, attempting to use a version of the actions after the deprecation date will result in a workflow failure. Artifacts within their retention period will remain accessible from the UI or REST API regardless of the version used to upload. This deprecation will not impact any existing versions of GitHub Enterprise Server being used by customers.
This announcement will also be added to actions/upload-artifact and actions/download-artifact. Please visit the documentation to learn more about storing workflow data as artifacts in Actions.
