+### Subtitle block and `parameters.componentSubtitle`
+
+The `Subtitle` block now accepts an `of` prop, which can be a reference to a CSF file or a default export (meta).
+
+`parameters.componentSubtitle` has been deprecated to be consistent with other parameters related to autodocs, instead use `parameters.docs.subtitle`.
+
## From version 7.x to 8.0.0
### Portable stories
