-# This uses a gentoo-created tarball due to Google CI Failures.
-# Use 133(?) as a base for new official tarballs.
+# Upstream roll their bundled Clang every two weeks, and the bundled Rust
+# is rolled regularly and depends on that. While we do our best to build
+# with system Clang, we may eventually hit the point where we need to use
+# the bundled Clang due to the use of prerelease features.

+# USE=bundled-toolchain is intended for users who want to use the same toolchain
+# as the upstream releases. It's also a good fallback in case we fall behind
+# and need to get a release out quickly (less likely with `dev` in-tree).
+
+# Since m133 we are using CI-generated tarballs from
+# https://github.com/chromium-linux-tarballs/chromium-tarballs/ (uploaded to S3
+# and made available via https://chromium-tarballs.distfiles.gentoo.org/).
+
+# We do this because upstream tarballs weigh in at about 3.5x the size of our
+# new "Distro tarballs" and include binaries (etc) that are not useful for
+# downstream consumers (like distributions).

+Subject: [PATCH] work around dead oauth2 credentials, correcting the previous bad patch
+
+Google doesn't let us bake in OAuth2 credentials, and for some time,
+Google sign-in has been broken. Arch dealt with this in March, and so
+did we to some degree, but in the last few months, our sign-in
+credentials have been broken. It appears that we actually did remove API
+credentials in March around Chrome 89, but they got added back, perhaps
+when rotating newer versions to replace older versions. Work around this
+by following Arch's lead: we remove the predefined credentials, as
+before, but also we patch Chromium so that people can use their own
+easily, using Arch's patch for that.
