+On Monday this week, we have released our [weekly release][2021W33] of the
+cheeses.
+
+[2021W33]: https://lists.sr.ht/~cnx/ipwhl-announce/%3CCDQ7HRSRNOHF.3TNAR9NHH0KV1%40nix%3E
+
+With the increasing number of packages declared in our repository, it is harder
+and harder to keep track and decide which packages to package next.  To address
+this, [McSinyx][cnx] has written a script to check which packages can be
+declared next:
+
+[cnx]: https://cnx.srht.site
+
+```python
+from importlib.metadata import distributions
+from glob import glob
+
+from packaging.utils import canonicalize_name
+
+def declared(project):
+    name = canonicalize_name(project).replace('-', '_')
+    return glob(f'ipwhl-data/pkgs/*/*/{name}-*')
+
+for distribution in distributions():
+    name = distribution.metadata['Name']
+    if declared(name): continue
+    for dep in distribution.metadata.get_all('Requires-Dist') or []:
+        if not declared(dep.split(maxsplit=2)[0]): break
+    else:
+        print(name)
+```
+
+On the other hand, I have written a [tracker page][status] to see how far we
+have progressed this project.  Packages that have not been declared yet are
+emphasized and colored red[^0].
+
+[status]: /projects/ipwhl/status/
+
+[^0]: I'm not sure if this is accessible enough for colorblind readers
+  and readers who use text browser or screen reader.  If you're aware of a
+  better way to highlight please tell me.
