LifeRing 5.08 has the ability pre-cache maps of a certain area and at a certain zoom level, so you can quickly recall them later when you might not have access to internet-based or server-based maps.  This is valuable when traveling

LifeRing 5.08 has the ability to access data from databases outside of LifeRing.  Past versions of LifeRing were dependent on data or content that was added by LifeRing users or received from external datalinks and stored in the LifeRing database
