Announcing Subsurface 4.9

The Subsurface development team proudly announces the release 4.9 of Subsurface, an open source dive log and dive planning program for Windows, Mac and Linux.

Some of the changes in Subsurface 4.9:

  • Major rewrite of the undo facility. Most operations can now be undone at a much finer granularity. With the exception of tanks and weights this removes the “edited” state in the UI
  • Dive sites as first class citizens with better user interface and ability to track them separately from dives, including the ability to export and import dive sites
  • Show surface gradient factor in infobox
  • Add ability to save dive data as subtitle file for videos
  • Split individual dive computers into distinct dives
  • Add stats by depth and temperature ranges to yearly stats
  • Allow to filter for logged/planned dives
  • Include average max depth in statistics
  • Planner: Allow for a final segment at the surface to display further desaturation
  • Planner: Add UI element for bailout planning for rebreather dives
  • Bluetooth: only show recognized dive computers by default
  • New LaTeX export option
  • Add media to closest dive, not all selected dives
  • Sort dives by number if at the same date
  • Fix bug in get_distance() to correctly compute spherical distance
  • Fix a bug related to non-ASCII characters in user names
  • Merge overlapping trips on import
  • Fix bug in cloud save after removing dives from a trip
  • Perform more accurate OTU calculations, and include OTU calculations for rebreather dives
  • Import: Small enhancements on Suunto SDE import
  • Import: Initial support for importing Mares log software
  • Dive computer support:
    • Add support for Mares Genius
    • Add support for Oceanic Geo 4.0
    • Add support for Scubapro Aladin H Matrix, G2 HUD
