+name: Run Release Please
+
+# Cuts the specification's releases. Until now its vX.Y.Z tags were created by hand, which
+# is easy to postpone and easy to get wrong; release-please proposes the next version and
+# the changelog as a pull request, and tags once that pull request is merged.
+#
+# The tag shape is unchanged: include-component-in-tag is false in release-please-config.json,
+# so a release is tagged vX.Y.Z, continuing from v0.9.0 rather than restarting. Versioning
+# stays below 1.0.0 for now, so a breaking change bumps the minor.
+#
+# This repository enforces DCO, so the bot's own commits need a sign-off too. That is the
+# signoff key in release-please-config.json: as of v5 it is a configuration-file option, and
+# an action input of the same name is ignored.
