no configureAudioSession in core anymore?

[brianomchugh]

I am just playing around with linphone 5.4 SDK with the iOS app-- and I notice that the following methods are removed, but I can't find any documentation on when and why they were deprecated:

• Core.callkitEnabled
• Core.configureAudioSession
• Core.activateAudioSession

But the most recent iOS tutorials still reference these values. If I try to comment them out, there is no audio on the calls. Any hint on how the newer SDK works with iOS?
