+- 💥[Feature] The `openedx-assets` command is replaced with `npm run` subcommands.
+  This will slightly reduce the build time for edx-platform assets and comprehensive themes.
+  It will also open up the door for more significant build time reductions in the future.
+  Here is a migration guide, where each command is to be run in the `lms` or `cms` container.
