+* Removed deprecated Otter Assign format v0
+* Disabled editing for question prompt cells in the notebooks generated by Otter Assign per [#431](https://github.com/ucbds-infra/otter-grader/issues/431)
+* Removed `ucbdsinfra/otter-grader` Docker image and made default image for Otter Grade `ubuntu:22.04` per [#534](https://github.com/ucbds-infra/otter-grader/issues/534)
+* Make `xeCJK` opt-in behavior for exporting notebooks via LaTeX per [#548](https://github.com/ucbds-infra/otter-grader/issues/548)
+* Convert from use of deprecated `PyPDF2` package to `pypdf`

+* Deprecated the `variables` key of the assignment config in favor of `generate.serialized_variables`
+* Enabled Otter Generate for all assignments created with Otter Assign

+* Removed `linux/amd64` platform specification for Docker images in Otter Grade
+* Updated Otter Assign to normalize notebooks before writing them with `nbformat.validator.normalize` per [#658](https://github.com/ucbds-infra/otter-grader/issues/658)
+* Added summary of assignment questions to Otter Assign logging per [#564](https://github.com/ucbds-infra/otter-grader/issues/564)
+* Converted to Mamba from Conda for package management in grading containers per [#660](https://github.com/ucbds-infra/otter-grader/issues/660)
+* Upgraded default Python version in grading containers from 3.7 to 3.9
+

-### Test Docker Images
-
-To build a Docker image suitable for testing, use the Makefile target `docker-test`. This will
-build a Docker image tagged `otter-test` which includes the development version of Otter in your 
-local copy of the repo as the installed version of Otter.
-
-```
-make docker-test
-```
-
-If you need to build testing images for grading assignments, use the `docker-grade-test` target to 
-edit the Dockerfile in `otter/grade` and then install your local copy of the rpeo:
-
-```
-make docker-grade-test
-pip install .
-```
-
-**Do not commit any changes made by this Makefile target.**
-
-Once you finish, make sure to run the `cleanup-docker-grade-test` target to undo your changes. 
-
-```
-make cleanup-docker-grade-test
-```
-
-
 ## Building the Documentation
 
 To build a local copy of the documentation, use the `docs` target of the Makefile.
