The Subsurface development team proudly announces release 4.4 of Subsurface, an open source divelog and dive planning program for Windows, Mac and Linux.

Binaries are available for Windows, Mac, and a number of Linux flavors (Ubuntu, Debian Jessie, Linux Mint, Fedora, and openSUSE). Please take a look at our Downloads page for details.

Some of the changes since Subsurface 4.3

Subsurface supports posting a dive with profile pictures and some of the relevant data to a user’s timeline on Facebook.

Subsurface now allows the user to select which of the dives downloaded from a dive computer will be added to the dive list.

We have added more capabilities to the CSV import for manually kept dive logs; this now includes start and end pressure for the main tank as well as air and water temperatures.

There is also a new interactive dialog that makes it much easier to identify the meaning of various columns in CSV import.

Subsurface can now import dive databases from the Cobalt divelog program.

Subsurface profile drawing has been sped up significantly which also improved the situation when using the visual editor to add dives or plan dives.

We have made more progress with PSCR support -- still not fully functional, but getting closer. It is now possible to select the type of a dive (OC, CCR, PSCR) in the UI.

Changes to a dive location on the globe now trigger dive edit mode and can be rejected. GPS coordinates are shown immediately when selecting a dive site on the globe.

For owners of the Heinrichs & Weikamp OSTC 3 and OSTC Sport Subsurface now supports updating the firmware and informs users of new firmware releases.
