## Source excerpt

Pssst! If you're an Android developer, you might not have heard yet...the N Preview started today! As part of the festivities, a new alpha version of the support libraries was released. There was no changelog that I could find, so I decided to make one. Here's what has changed (so far) in the public API of a few of these libraries: Support-V4: diff -U 0 -N support-v4-23.2.0_df13b086/android.support.v4.app.FragmentController support-v4-24.0.0-alpha1_41849fd4/android.support.v4.app.FragmentController --- support-v4-23.2.0_df13b086/android.support.v4.app.FragmentController 2016-03-09 19:28:24.000000000 -0500 +++ support-v4-24.0.0-alpha1_41849fd4/android.support.v4.app.FragmentController 2016-03-09 19:28:24.000000000 -0500 @@ -11,0 +12 @@ + public void restoreAllState(android.os.Parcelable, android.support.v4.app.FragmentManagerNonConfig); @@ -12,0 +14 @@ + public android.support.v4.app.FragmentManagerNonConfig retainNestedNonConfig(); diff -U 0 -N support-v4-23.2.0_df13b086/android.support.v4.app.FragmentManagerNonConfig support-v4-24.0.0-alpha1_41849fd4/android.support.v4.app.FragmentManagerNonConfig --- support-v4-23.2.0_df13b086/android.support.v4.app.FragmentManagerNonConfig 1969-12-31 19:00:00.000000000 -0500 +++ support-v4-24.0.0-alpha1_41849fd4/android.support.v4.app.FragmentManagerNonConfig 2016-03-09 19:28:24.000000000 -0500 @@ -0,0 +1,2 @@ +public class android.support.v4.app.FragmentManagerNonConfig { +} diff -U 0 -N support-v4-23.2.0_df13b086/android.support.v4.app.FragmentTransaction support-v4-24.0.0-alpha1_41849fd4/android.support.v4.app.FragmentTransaction --- support-v4-23.2.0_df13b086/android.support.v4.app.FragmentTransaction 2016-03-09 19:28:24.000000000 -0500 +++ support-v4-24.0.0-alpha1_41849fd4/android.support.v4.app.FragmentTransaction 2016-03-09 19:28:24.000000000 -0500 @@ -34,0 +35,2 @@ + public abstract void commitNow(); + public abstract void commitNowAllowingStateLoss(); diff -U 0 -N support-v4-23.2.0_df13b086/android.support.v4.content.Conte
