 # @backstage/plugin-techdocs
 
+## 0.5.5
+
+### Patch Changes
+
+- 5fa3bdb55: Add `href` in addition to `onClick` to `ItemCard`. Ensure that the height of a
+  `ItemCard` with and without tags is equal.
+- e44925723: `techdocs.requestUrl` and `techdocs.storageUrl` are now optional configs and the discovery API will be used to get the URL where techdocs plugin is hosted.
+- 019fe39a0: Switch dependency from `@backstage/plugin-catalog` to `@backstage/plugin-catalog-react`.
