 # Changelog
 
+## 0.56.1 - 2023-11-12
+
+### Changes
+
+**Fix `uvicorn[standard]` version** (be409c4)
+
+Uvicorn was updated to version 0.23.2 in 2590d8a and 0.56.0, but the
+version number for `uvicorn[standard]` was not updated correspondingly.
+This release will update `uvicorn[standard]` to 0.23.2.
+
+**Update to Material for MkDocs 9** (ab692a3, 90f75b0)
+
+Docs will now be built with
+[Material for MkDocs 9](https://squidfunk.github.io/mkdocs-material/changelog/).
+The most notable user-facing change is the new dark theme color palette,
+which has undergone a few small changes since its release in version
+9.4.0 (https://github.com/squidfunk/mkdocs-material/issues/6061).
+Code block copy behavior has undergone some small changes as well. Code
+blocks in the documentation have been reformatted for easier copying.
