Pristine upstream, unpacked from the official wordpress.org tarball. https://wordpress.org/wordpress-7.1.1.tar.gz sha1 2a9d68474e8703aa3a66f80427b325e0941b6a1e (published by wordpress.org) sha256 3996fee13448ef12e07e9f0c77db2f655ffa1b7cde71c80a4965d3bf1fb956b3 This branch carries nothing but upstream releases, one commit each, and is never edited. It is the other side of the git-subtree merge that brings security releases into SiriusPress/wordpress/ — see SiriusPress/docs/upstream-merges.md.
