This release includes a number of minor improvements and important bug fixes.

New Features

You can now use 0 as an android:defaultValue for reference arguments.

Behavior changes

Exact deep link matches are now prioritized over deep links with .* or argument matches.

Bug Fixes

popBackStack() and navigateUp now correctly return false when popping the last destination on the back stack, fixing a regression introduced in 1.0.0-beta01.

Navigation now correctly sets the ClassLoader during restoration of saved instance state, avoiding issues when using custom classes in Navigator saved state or in arguments sent to a NavDestination. 

Safe Args generated NavArgs classes no longer crash when restoring a Parcelable[] argument from saved instance state.

Safe Args now properly cleans up unnecessary generated Kotlin classes.
