Version 2.7

Release Summary

The 2.7 version replaces the beta 2.6 version with an operational version of the new portal. Enhancements were made to partition real-time from historical data feeds to quicken load speeds. Additionally, real-time conditions are available on a mouse hoiver and persist to selected data views.
