+### Changed
+
+- The CLI entrypoint is now `pypi-attestations` 
+  ([#82](https://github.com/trailofbits/pypi-attestations/pull/82))
+- The CLI `verify` subcommand has been changed to `verify attestation`,
+  as in `pypi-attestations verify attestation --identity ...`
+  ([#82](https://github.com/trailofbits/pypi-attestations/pull/82))
+
+### Added
+- The CLI has a new subcommand `verify pypi`, which takes a URL to a
+  PyPI distribution (either a wheel or a source distribution) and a
+  GitHub/GitLab repository. The command verifies the distribution by
+  downloading it and its provenance from PyPI, verifying them using
+  `sigstore` and checking that the repository matches the one in the
+  PyPI provenance file.
