- [Bugfix] Fix ORA2 file uploads in CMS. As the cache settings are shared between CMS and LMS, the settings are moved from `common_lms.py` to `common_all.py`. (by FatemeKhodayari)

- [Improvement] No more large dev images. This was fixed by adding `--no-log-init` option to useradd command and reducing space usage of `/var/log/faillog`. (by CodeWithEmad)
- [Improvement] Upgrade the Open edX default version to open-release/palm.3. (by regisb)

- [Improvement] Adds `connect=False` to the LMS and CMS' MongoDB connection to prevent `ServerSelectionError` after a cluster failover. (by open-craft)

- 💥[Bugfix] Apply "fix mysql crash after upgrade to Palm" from 16.1.0 to `tutor k8s` deployments, as well. Users previously running `tutor k8s` with `RUN_MYSQL: true`, with any version between 16.0.0 and 16.1.0 including, might have to fix their data manually. For users running `tutor local`, this change has no effect, as the underlying issue was already fixed in 16.1.0. For users running `tutor k8s` with `RUN_MYSQL: false`, this change is also a no-op.

- [Improvement] Improve support of legacy non-BuildKit mode: (by regisb)
- [Bugfix] Fix building of openedx Docker image.
- [Improvement] Remove `--cache-from` build option.
- [Improvement] Add a warning concerning the lack of support of the `--build-context` option.
- 💥[Bugfix] Fix mysql crash after upgrade to Palm. After an upgrade to Palm, the mysql client run by Django defaults to a utf8mb4 character set and collation, but the mysql server still runs with utf8mb3. This causes broken data during migration from Olive to Palm, and more generally when data is written to the database. To resolve this issue, we explicitely set the utf8mb3 charset and collation in the client. Users who were running Palm might have to fix their data manually. In the future we will upgrade the mysql server to utf8mb4. (by regisb)
- [Improvement] We upgrade to MySQL 8.1.0 to avoid having to restart the server after the upgrade.
- [Bugfix] Ask whether user wants to run locally during `tutor local launch`. (by regisb)
- [Bugfix] Fix a race condition that could prevent a newly provisioned Studio container from starting due to a FileExistsError when creating logs directory.
