问题
I'm applying Android 6.0 runtime permissions into an app which listens to carrier data connection state changes. I first tried to just remove the READ_PHONE_STATE from the manifest to check where the app requires the permission. To my surprise the app didn't crash at all.
After this I've tried the same installation on two pre 6.0 devices which did actually crash on it. To me it seems like Android 6.0 does no longer require the permission. Is there any way to confirm this?
The line below is the one on which the pre 6.0 devices crashes:
tm(TelephonyManager).listen(this, PhoneStateListener.LISTEN_DATA_CONNECTION_STATE);

Yes, this commit removes the request of READ_PHONE_STATE when register the event type LISTEN_CALL_STATE, LISTEN_DATA_ACTIVITY and LISTEN_DATA_CONNECTION_STATE:
Do not enforce PHONE_STATE_PERMISSION to register listener PHONE_STATE_PERMISSION should not be required to register to the following event types:
- PhoneStateListener.LISTEN_CALL_STATE
- PhoneStateListener.LISTEN_DATA_ACTIVITY
- PhoneStateListener.LISTEN_DATA_CONNECTION_STATE
In case of LISTEN_CALL_STATE, an empty string should be passed instead of incomingNumber, when caller has no PHONE_STATE_PERMISSION.

The documentation on developer.android.com was updated and correctly shows that the permission are not required.
If your code doesn't need the permission READ_PHONE_STATE for other reason apart from LISTEN_DATA_CONNECTION_STATE you can change your AndroidManifest.xml adding maxSdkVersion to the uses-permission:
<uses-permission android:name="android.permission.READ_PHONE_STATE" android:maxSdkVersion="22" />

There is no special permission listed for PhoneStateListener.LISTEN_DATA_CONNECTION_STATE in the official android documentation.
