Update Crashlytics.
Fix showing upload/posting progress views after seeing preview.
Fix possible unreadable text color when restoring compose view from state.
Fix showing images-for-upload in "new thread" previews.
Long-press "post" button to preview posts even when "confirm new posts" setting is off.

Switch PM action button to "reply" button.
Formatting.
