After update config.xml differs from new ionic project

I just updated my project using the changelog guide.
After updating my project and comparing it to a newly generated project the config.xml files differ, mainly in the breakout of the resources for ios/android.


 <platform name="android">
    <allow-intent href="market:*"/>
  <platform name="ios">
    <allow-intent href="itms:*"/>
    <allow-intent href="itms-apps:*"/>

new snippet:

<platform name="android">
    <allow-intent href="market:*"/>
    <icon src="resources/android/icon/drawable-ldpi-icon.png" density="ldpi"/>
    <icon src="resources/android/icon/drawable-mdpi-icon.png" density="mdpi"/>
    <icon src="resources/android/icon/drawable-hdpi-icon.png" density="hdpi"/>
    <icon src="resources/android/icon/drawable-xhdpi-icon.png" density="xhdpi"/>
    <icon src="resources/android/icon/drawable-xxhdpi-icon.png" density="xxhdpi"/>
    <icon src="resources/android/icon/drawable-xxxhdpi-icon.png" density="xxxhdpi"/>
    <splash src="resources/android/splash/drawable-land-ldpi-screen.png" density="land-ldpi"/>
    <splash src="resources/android/splash/drawable-land-mdpi-screen.png"

I am also missing these 2 lines:

<preference name="SplashScreen" value="screen"/>
<preference name="SplashScreenDelay" value="3000"/>

Have I missed something in the migration, or possibly a plugin?
