-Difficulty chart would fail to populate if the shared_pages.difficulty setting was 'Hybrid' and is now handled properly. The chart now supports 2 datasets: POW and POS -NetworkHistory.difficulty field was renamed to difficulty_pow and a new difficulty_pos field was added -The shared_pages.page_header.network_charts.difficulty_chart.line_color setting was renamed to pow_line_color -The shared_pages.page_header.network_charts.difficulty_chart.fill_color setting was renamed to pow_fill_color NOTE: If you have existing NetworkHistory data from before this update, it will be automatically assumed to be POW. If it was actualy POS, you will need to either manually fix the data in mongo or simply wait a couple hours while syncing to eventually push the old data out of the chart
