 For a complete example implementation,
 [check out the OHIFCornerstoneViewport's Toolbar Module](https://github.com/OHIF/Viewers/blob/master/extensions/cornerstone/src/toolbarModule.js).
 
+##### Toolbar Custom Component
+
+Toolbar elements can define its own custom react component to be consumed when rendering it. So far, it accepts `Functional` and `Class` Components. For that, you just need to expose your `CustomToolbarComponent` as the value of key `CustomComponent`. In case the property `CustomComponent` is not present, a default toolbar component will be used to render it. See bellow
+
+```js
+definitions: [
+...
+    {
+        id: 'Custom',
+        label: 'Custom',
+        icon: 'custom-icon',
+        CustomComponent: CustomToolbarComponent,
+    }
+...
+]
+
+```
+`CustomComponent` components will receive the following props:
+- parentContext: parent context. (In most of the cases it will be a ToolbarRow instance)
+- toolbarClickCallback: callback method when clicking on toolbar
+- button: its own definition object
+- key: react key prop
+- activeButtons: list of active elements
+- isActive: if current

+### Features
+
+* Use QIDO + WADO to load series metadata individually rather than the entire study metadata at once ([#953](https://github.com/OHIF/Viewers/issues/953)) ([9e10c2b](https://github.com/OHIF/Viewers/commit/9e10c2b))

+
+
+### Bug Fixes
+
+* Temporarily sort SEG files to the end of the display set list as a workaround for several metadata issues ([#987](https://github.com/OHIF/Viewers/issues/987)) ([b3b4c10](https://github.com/OHIF/Viewers/commit/b3b4c10))

+
+
+### Bug Fixes
+
+* Check for Value in 00081155 sequence (Few patient protocol images doesn't have this value) and removed a duplicate declaration ([#921](https://github.com/OHIF/Viewers/issues/921)) ([d0ec9cf](https://github.com/OHIF/Viewers/commit/d0ec9cf))

+
+### Bug Fixes
+
+* 🐛 Add DicomLoaderService & FileLoaderService to fix SR, PDF, and SEG support in local file and WADO-RS-only use cases ([#862](https://github.com/OHIF/Viewers/issues/862)) ([e7e1a8a](https://github.com/OHIF/Viewers/commit/e7e1a8a)), closes [#838](https://github.com/OHIF/Viewers/issues/838)
