• Commits,

Milestone, API reference

• 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 nowResource.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*.
