 Maintainer Notes:
-Release builds calculate version code dynamically. This is unsuitable for us
-because it depends on date and time. Use default version code (supposed to be
-used in debug builds): it's a well-formed static constant bumped every release.
+Cannot use AUM/UCM because version code is not updated, see
+https://github.com/mozilla-mobile/focus-android/issues/1528.
+
+Increment version code by 1 on each release.
