+# 0.24 (2018-09-21)
+
+* [Commits](https://github.com/mozilla-mobile/android-components/compare/v0.23...v0.24),
+[Milestone](https://github.com/mozilla-mobile/android-components/milestone/24?closed=1),
+[API reference](https://mozilla-mobile.github.io/android-components/api/0.24/index)
+
+* Compiled against:
+ * Android
+ * SDK: 27
+ * Support Libraries: 27.1.1
+ * Kotlin
+ * Standard library: 1.2.61
+ * Coroutines: 0.23.4
+ * GeckoView
+ * Nightly: 64.0.20180905100117
+ * Beta: 63.0b3 (0269319281578bff4e01d77a21350bf91ba08620)
+ * Release: 62.0 (9cbae12a3fff404ed2c12070ad475424d0ae869f)
+
+* **dataprotect**:
+ * Added a component using AndroidKeyStore to protect user data.
+ ```kotlin
+ // Create a Keystore and generate a key
+ val keystore: Keystore = Keystore("samples-dataprotect")
+ keystore.generateKey()
+
+ // Encrypt data
+ val plainText = "plain text data".toByteArray(StandardCharsets.UTF_8)
+ val encrypted = keystore.encryptBytes(plain)
+
+ // Decrypt data
+ val samePlainText = keystore.decryptBytes(encrypted)
+ ```
+* **concept-engine**: Enhanced settings to cover most common WebView settings.
+* **browser-engine-system**:
+ * `SystemEngineSession` now provides a way to capture a screenshot of the actual content of the web page just by calling `captureThumbnail`
+* **browser-session**:
+ * `Session` exposes a new property called `thumbnail` and its internal observer also exposes a new listener `onThumbnailChanged`.
+
+ ```Kotlin
+ session.register(object : Session.Observer {
+ fun onThumbnailChanged(session: Session, bitmap: Bitmap?) {
+ // Do Something
+ }
+ })
+ ```
+
+ * `SessionManager` lets you notify it when the OS is under low memory condition by calling to its new function `onLowMemory`.
+
+* **browser-tabstray**:
+
+ * Now on `BrowserTabsTray` every tab gets is own thumbnail :)
+
+* **support-ktx**:
+
+ * Now you can easily query if the OS is under low memory conditions, just by using `isOSOnLowMemory()` extension function on `Context`.
+
+ ```Kotlin
+ val shouldReduceMemoryUsage = context.isOSOnLowMemory()
+
+ if (shouldReduceMemoryUsage) {
+ //Deallocate some heavy objects
+ }
+ ```
+
+ * `View.dp` is now`Resource.pxtoDp`.
+
+ ```Kotlin
+ // Before
+ toolbar.dp(104)
+
+ // Now
+ toolbar.resources.pxToDp(104)
+ ```
+* **samples-browser**:
+ * Updated to show the new features related to tab thumbnails. Be aware that this feature is only available for `systemEngine` and you have to switch to the build variant `systemEngine*`.
