Alright! Found it in the commits to the nighly builds:
There is a new config option for views:
$ionicConfigProvider.views.swipeBackEnabled(false);
This disables the Swipe to go back feature. It’s only good if view cache is enabled, which is not possible for me because it acts odd (shows same views on all pages even though different urls etc).
Also, to solve to open menu on all pages with back button enabled. Add this to ion-side-menus:
enable-menu-with-back-views="true"
