A new major release arrived today, Subsurface 4.6, which introduces numerous exciting new features. Prominent ones include heatmap visualization of deco tissue loading, support for importing DAN DL7, SmartTrack (.slg), and Underwater Technologies AV1 log files, and revamped Facebook access from the GUI. The visualization and handling of dive computer events have been improved in the dive profile, allowing the user to group them into info, alert, and warning. Surface intervals and dive runtimes will now be prominently displayed in the planner, and separate deco models are now available for both the planned and the log.
