You can change back to the way it worked in Wowza Media Server 2 by adding the following properties to the HTTPStreamer/Properties container in [install-dir]/conf/[application]/Application.xml (be sure to get the correct <Properties> container - there are several in Application.xml):
Set cupertinoRelativePlaylistPlaylists to false to enable absolute urls in the returned playlist.m3u8 url.
<Property> <Name>cupertinoRelativePlaylistPlaylists</Name> <Value>false</Value> <Type>Boolean</Type> </Property>
<Property> <Name>cupertinoRelativePlaylistItems</Name> <Value>false</Value> <Type>Boolean</Type> </Property>
