# 0.24 (2018-09-21)
* 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*`.
