   * Added new toolbar APIs:
   ```kotlin
+  val toolbar = BrowserToolbar(context)
   toolbar.textColor: Int = getColor(R.color.photonRed50)
   toolbar.hintColor: Int = getColor(R.color.photonGreen50)
   toolbar.textSize: Float = 12f
   toolbar.typeface: Typeface = Typeface.createFromFile("fonts/foo.tff")
   ```
-    These attributes are also available in XML (except for typeface):
-  ```xml
-  <mozilla.components.browser.toolbar.BrowserToolbar
-    android:id="@+id/toolbar"
-    app:browserToolbarTextColor="#ff0000"
-    app:browserToolbarHintColor="#00ff00"
-    app:browserToolbarTextSize="12sp"
-    android:layout_width="match_parent"
-    android:layout_height="wrap_content"/>

 * **concept-storage**:
   * Added a new concept for describing an interface for storing browser data. First iteration includes a description of `HistoryStorage`.

   Before adding a first session to the engine, initialize the history tracking feature:
   ```kotlin
   val historyTrackingFeature = HistoryTrackingFeature(
-    components.engine,
-    components.historyStorage
+      components.engine,
+      components.historyStorage
   )
   ```
   Once the feature has been initialized, history will be tracked for all subsequently added sessions.
 * **sample-browser**:
   * Updated the sample browser to track browsing history using an in-memory history storage implementation (how much is actually tracked in practice depends on which engine is being used. As of this release, only `SystemEngine` provides a full set of necessary APIs).
 * **lib-crash**
   * Added option to display additional message in prompt and define the theme to be used:
-  ```Kotlin
-    CrashReporter(
-    promptConfiguration = CrashReporter.PromptConfiguration(
-      // ..
+  ```kotlin
+  CrashReporter(
+      promptConfiguration = CrashReporter.PromptConfiguration(
+        // ..
 
-      // An additional message that will be shown in the prompt
-      message = "We are very sorry!"
+        // An additional message that will be shown in the prompt
+        message = "We are very sorry!"

   ).install(applicationContext)
   ```
   * Showing the crash prompt won't play the default activity animation anymore.
