From September 2nd, 2024, we will no longer include hidden files and folders as part of the default upload of the v3 and v4 upload-artifact actions. This reduces the risk that credentials are accidentally uploaded into artifacts. Customers who need to continue to upload these files can use a new option, ‘include-hidden-files’, to continue to do so.
