Modern Android libraries are starting to phase out support for Android 5 (API levels 21 to 22). This makes sense to me since Android 6 was released 10 years ago.

Since a lot of libraries are no longer supporting Android 5 it means that to keep dependencies updated, Summit can no longer support Android 5 either.

If this is a huge concern to any users of Summit please flag in the comments. Otherwise I will be removing support for these versions of Android in the next release.
