+### Workspace-aware changelogs
+
+When you select a Craft release workspace, automatic changelogs include commits
+that change files in that workspace and commits that change shared files outside
+all workspaces. Commits confined to another workspace are excluded. Craft detects
+package ownership from pnpm, npm, or Yarn workspaces as well as the release
+workspaces in `.craft.yml`. Commits spanning workspaces appear in each affected
+workspace's changelog. This also scopes automatic version detection; single-unit
+repositories keep their existing behavior.
+
+If a release includes files from another workspace, add its directory to
+`includePaths` on that release unit. Paths are relative to the repository root,
+match whole directory names, and cannot escape the repository:
+
+```yaml
+workspaces:
+  packages/cli:
+    changelog:
+      policy: auto
+      includePaths:
+        - apps/cli-docs
+```
+
+Most workspaces need no `includePaths` setting.
+
 ### Title Stripping (Default Behavior)
 
 By default, conventional commit prefixes are stripped from changelog entries.
