## Dimension integration manager has been removed from the playbook
The [Dimension integration manager](./docs/configuring-playbook-dimension.md) has been removed from the playbook, as it has been unmaintained.
The playbook will let you know if you're using any `matrix_dimension_*` variables. You'll need to remove them from `vars.yml` and potentially [uninstall the component manually](./docs/configuring-playbook-dimension.md#uninstalling-the-component-manually).
## (BC Break) Hydrogen role has been relocated and variable names need adjustments
The role for Hydrogen has been relocated to the [mother-of-all-self-hosting](https://github.com/mother-of-all-self-hosting) organization.
