The Subsurface development team proudly announces the release 4.9.8 of Subsurface, an open source dive log and dive planning program for Windows, Mac and Linux.

This release fixes a number of issues in 4.9.7 and adds a couple of new features. The highlight is the new, significantly more flexible dive list filtering setup. Some of the changes in Subsurface 4.9.8:

new features:

  • filter: more flexible filtering system based on individual constraints

  • add Garmin Descent Mk2/Mk2i support for Linux, macOS, and 64bit Windows

  • add Scubapro Aladin A2 support

  • desktop: allow adding dives to arbitrary trips

  • equipment: use pO2 from prefernces for MOD display

  • core: make device management undoable

  • Windows: add separate 32bit and 64bit builds - the 32bit build does NOT support the Garmin Descent Mk2/Mk2i


  • desktop: improve the appearance in dark mode

  • desktop: fix crash on drag&drop into tag widgets [#3030]

  • desktop: respect page-up, page-down, home and end keys for selection change [#2957]

  • core: improve merging of cylinder pressures [#2884]

  • macOS: fix issue with HID dive computers like Suunto Eon Core/Steel [#2999]
