Starting with Drupal 8.8.0, the Content Moderation and Workspaces modules are no longer incompatible, so they can be installed and used together.
When both modules are installed, the Latest revision local task provided by Content Moderation is no longer available because Workspaces always shows the latest workspace-specific revision on the canonical entity view page (e.g. /node/1
).
Additionally, when a moderation workflow is enabled for an entity type/bundle and if there are entities in draft (non-default/unpublished) moderation states in a workspace, that workspace can not be published to Live until all the draft entities reach a publishable moderation state.
