  • Improved detection of OpenGL versions (prevents potential crash on more operating systems with ancient gfx drivers)
  • Improve the map widget editing behavior. Allow updating the location of a marker that is being edited by entering new coordinates in the text field in “real-time”. Also, don’t place new markers at the 0,0 coordinate and instead place them at the current map center.

New in Subsurface 4.7.2 (Nov 1, 2017)

  • Fix potential crash when running with French localization and downloading dives from a dive computer
  • Fallback to old behavior if Facebook album creation fails
  • Fix UI issue when adding dives to trip below
  • Fix UI issue when closing filters
  • Add small behavior changes to the map widget

  • Fix error where newly created cloud accounts failed to create the remote repository on Windows
  • Detect and try to work around the fact that the map module requires at least OpenGL 2.1 (previously Subsurface would crash when OpenGL was too old -- often on old Win32 versions)

New in Subsurface 4.7.1 (Oct 23, 2017)

  • Add support for OSTC 4 configuration.
  • User interface changes:
  • New map widget. No more rotating globe, but much better support for the underlying widget -- so overall an improvement.
  • Many small bug fixes and tweaks.
  • Green gas change icon when switching to EAN100
  • Imports and exports:
  • Better support for importing dive data from Shearwater desktop, DL7, Datatrak and other 3rd party formats.
  • Dive planner:
  • Improved and more user friendly cylinder handling
  • Print delta pressure for minimum gas calculation in results
  • Identify overlapping dives when calculating dive plan
  • Compute plan variations: How does decompression time change when changing the bottom time by one minute or the depth by one meter?
  • Faster planning for long decompression times
  • Dive computer support:
  • Early and limited support for Bluetooth LE dive computers. Currently BLE isn’t supported at all on Windows due to lack of support for Windows in the underlying toolkit that we use. BLE appears to work reasonably well on Mac and works on Linux if Subsurface is built against Qt 5.9.2 or newer. Older versions of Qt will give you mixed results, depending on the specific dive computer you use. Side note for those on Windows or a Linux distro that doesn’t allow BLE support just yet: you can use Subsurface-mobile 2.0 or later on Android and download from your BLE dive computer there and then transfer the dive data via Subsurface cloud storage.
  • Support for multiple tank sensors reporting pressure at the same time. This is something that we hadn’t seen before outside of CCR dives, but some newer dive computers support this for example for side mount divers. We now correctly download these data from the dive computers that support it, store and retrieve the pressure data, and visualize multiple tank pressure readings at the same time.
  • Add support for the following dive computers:
  • Aqualung i200
  • Cochran Commander II, Commander TM
  • Dive Systems/Ratio iDive2 Deep, iDive2 Easy, iDive2 Free, iDive2 Tech+, iX3M Deep, iX3M Easy, iX3M Pro Deep, iX3M Pro Easy, iX3M Pro Tech+, iX3M Reb, iX3M Tech+
  • Heinrichs Weikamp OSTC+
  • Shearwater Perdix AI (only available where BLE is supported)
  • Suunto D4f

New in Subsurface 4.5.2 (Nov 8, 2015)

  • This release only adds a few small updates to our dive computer support, including support for downloading dives from OSTC dive computers with the latest firmware.

New in Subsurface 4.5.1 (Nov 8, 2015)

  • Several errors in translations were fixed, one of which could cause a crash when running Subsurface in German and using the dive planner.
  • Many translations have been improved, especially the Hebrew translation has made a huge leap forward and is now complete.
  • Two issues related to our integration with divelogs.de were addressed: uploads now work from Windows and uploads from all platforms now correctly recreate location / site information if that information had previously been downloaded from divelogs.de.
  • We fixed a problem that caused a situation where in some environments users weren’t able to edit the print templates.
  • The Suunto EON Steel is now supported on Mac.
  • Tank sizes set on the Suunto EON Steel are now downloaded and added on the equipment tab of the dive.
  • Further support for free divers.
  • Several algorithmic improvements leading to better profiles, better SAC rate visualization, and better detection of the time offset when matching pictures to dives.
  • We fix several UI issues.

New in Subsurface 4.5 (Oct 15, 2015)

  • Additional ways to store divelogs. Subsurface cloud storage is now available for a user’s dive data. Now it’s simple to call up your data from any computer running Subsurface, protected with a user name and password. You can even access your data via the web.
  • Dives now reference to dive sites, making it easier to maintain a set of set of sites that can be used again when the user repeatedly dives at the same location. Notes and descriptions of dive sites can now be added as well.
  • GPS data can be used to look up the closest body of water, country, or city
  • Improved print support, letting users customize formats for printing
  • Improved Bluetooth device support
  • VPM-B support for dive planning, giving users a choice of deco algorithms (now works with both Buhlmann ZH16 and VPM-B)
  • Recreational dive planner mode which computes the remaining bottom time for a diver that avoids mandantory decompression stops and stays within the given amount of gas
  • Improved support for freediving
  • Improved image import and management
  • Partial Undo/Redo functionality added
  • Ability to load dives exported with OSTCT tools
  • Additional upgrades include fixes for importing third party files and CSV files, support for more GPS coordinate formats, better SAC rate calculations and many other fixes.

New in Subsurface 4.5 Beta 1 (Sep 4, 2015)

  • Cloud storage:
  • Subsurface offers a cloud storage backend that allows using the same dive data from multiple computers. Accounts are free and tied to an email address. An account can easily be created from within Subsurface (Preferences, Network tab; simply enter a valid email address and a password). After the user receives a verification pin and enters this in the corresponding field in the Preferences all is set up and the cloud storage can be transparently used from within Subsurface. While this is nice for many users who have more than one computer on which they use Subsurface, it is espcially useful with our upcoming Subsurface-mobile app on Android (the beta test for that will start soon).
  • Web view:
  • Dives stored in the Subsurface cloud storage backend can also be accessed with a web interface. Simply go to https://cloud.subsurface-divelog.org/user/

New in Subsurface 4.4.2 (May 5, 2015)

  • Highlights:
  • Improved editing of tags when multiple dives are selected.
  • Improved handling of the sample interval when uploading data to divelogs.de
  • Fixed several issues with downloads from the UEMIS SDA
  • Added support for the new models of the Heinrichs & Weikamp OSTC 2 and OSTC 3
  • Added support for the Tusa IQ-700
  • Added support for the Mares Smart
  • Added more DiveSystems iDive models
  • Added support for Scubapro Meridian and Chromis
  • Added / improved support for Oceanic Veo 2, Veo 3 and VTX

New in Subsurface 4.4.1 (Feb 19, 2015)

  • Spanish, Russian and French translations of the user manual have been updated.
  • Better and more flexible parsing of GPS coordinates.
  • Small fixes to the HTML export.
  • Fixed a problem where dives imported from some Shearwater dive computers would be considered CCR dives. For dives imported in the past, manually setting them to OC works around the issue.
  • Several fixes to imports from other divelog, including importing from MacDive.
  • New build script that should make it easier to build Subsurface from source on Linux distribution we don’t provide packages for.

New in Subsurface 4.4.0 (Feb 5, 2015)

  • 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.
  • 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.
  • Add support for importing logs from the Divesoft Freedom

New in Subsurface 4.4 Beta 3 (Feb 2, 2015)

  • Lots and lots of small fixes and improvements (especially for the CSV import) but most interestingly a late new feature that had been waiting for approval from Facebook: you can now connect Subsurface with your Facebook account and post a dive profile and some of the corresponding information directly to your time line.

New in Subsurface 4.4 Beta 2 (Jan 26, 2015)

  • 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.
  • We added support for importing logs from the Divesoft Freedom.
  • 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.

New in Subsurface 4.3 (Dec 18, 2014)

  • Subsurface now supports flexible filtering of the dive list. When the filter is opened,one can specify a combination of different criteria like tags, people who were on the dive, dive site, suit, etc. While filtering one can see how many dives
  • match any of the criteria, and how many dives match the combination of the selected criteria.
  • When editing a dive, one can now copy information about a dive and paste it into one or more other dives. This makes it easy to add the same equipment, buddies, tags or other aspects of a dive into a group of dives with similar characteristics.
  • The dive profile now offers an easy to understand tissue saturation graph that shows tissue saturation at any point during the dive.
  • In the dive profile one can turn on an improved visualization of the gas combinations used during a dive (aka “tank bar” with different gases represented by different colours, see image above).
  • Owners of the Heinrichs & Weikamp OSTC 2 and 3 as well as dive computers in the popular Suunto Vyper family of dive computers can configure the settings of their dive computers using Subsurface.
  • For a number of dive computers Subsurface now downloads additional data and shows them in a new tab on the screen. This includes (depending on the dive computer) information like battery levels, no fly times, Gradient Factors used during the dive, etc. This feature is enabled in all official Subsurface binaries and includes the Uemis Zurich SDA. When building from source this requires a custom version of libdivecomputer (as explained in the INSTALL file).
  • The dive planner now offers the ability to re-plan dives and to create duplicate dive plans in order to plan multiple scenarios.
  • We added support for several new dive computers including the Suunto EON Steel, Aeris A300 CD, and Aeris F11.
  • Subsurface can now import dive logs from Liquivision and Cochran software as well as the new Suunto DM5.
  • We made many improvements for UDDF and CSV import, UDDF export now complies with the latest version of the standard.
  • Many issues with the HTML export were addressed.
  • Initial support for closed circuit rebreathers (CCR) and pSCR was added. Dive logs from the Poseidon MkVI CCR can be imported. Visualization of dive logs as well as dive planning should work -- but this feature is fairly early in its development and we assume that there may be a few bugs and mis-features hidden in this area.
  • Other notable improvements:
  • Import of manually logged dives (e.g., from an existing paper logbook) is now much better documented in the user manual. Instead of having to individually enter each dive with the graphical profile editor users can add all their dives in a spreadsheet and import the data from there into Subsurface in one single operation.
  • Many other small improvements to the planner
  • Many small UI changes for better use on small displays (tighter columns and column headers on the dive list, the toolbox of icons no longer
  • forces a minimum height of the profile, etc)
  • Improvements on HiDPI displays
  • We fixed an annoying bug where when starting to edit a dive the pop-up with completions would cover the edit line (this usually happened when editing tags)
  • For the (rather unusual) dive computers that send a heading event in every sample we automatically declutter the profile display now
  • The Windows installer is smarter: the 64bit installer refuses to install its binaries on a 32bit OS and conversely the installer warns you when installing 32bit binaries on a 64bit OS
  • Better synchronization with divelogs.de, including support for multiple tanks

New in Subsurface 4.3 Beta 1 (Nov 20, 2014)

  • Quick summary of the highlights:
  • Multi filter: filter the dive list by many criteria including tags, people who were on the dive, location, suit, etc
  • Cut and paste support when editing dives: copy selected components of a dive and paste them into one or more other dives. This makes it easy to add the same equipment, buddies, tags or other aspects of a dive into others
  • Tissue saturation visualization
  • Configuration of the OSTC 2 and 3 as well as the Suunto Vyper family of dive computers
  • Support for extra data that can be downloaded from some dive
  • computers, including information like battery levels, no fly times,
  • Gradient Factors used during the dive, etc (only as supported by the
  • dive computer, at the time of this writing this requires a custom
  • version of libdivecomputer oder a Uemis Zurich SDA)
  • Better visualization of the gases used during a dive (“tank bar”)
  • Ability to re-plan dives
  • Support for several new dive computers including the Suunto EON Steel, Aeris A300 CD, Aeris F11 (Suunto EON Steel support is included with the Windows binaries but requires a patched version of libdivecomputer when building from source -- we expect the necessary patches to be upstream, soon)
  • Import dive logs from Liquivision and Cochran software
  • Import dive logs from the Poseidon Mk6 CCR
  • Import dive logs from Suunto DM5
  • Many improvements for UDDF and CSV import
  • Many improvements to HTML export
  • Many small improvements to the planner
  • Many small UI changes for better use on small displays (tighter columns and column headers on the dive list, the toolbox of icons no longer forces a minimum height of the profile, etc)
  • Improvements on HiDPI displays
  • Fix annoying bug where when starting to edit a dive the pop-up with completions would cover the edit line (this usually happened when editing tags)
  • Declutter profile for dive computers that send a heading event in every sample
  • on Windows, prevent installation of 64bit binaries on 32bit OS and warn when installing 32bit binaries on 64bit OS
  • support multiple tanks when syncing with divelogs.de
  • Experimental CCR and PSCR support

New in Subsurface 4.2 (Aug 9, 2014)

  • The Mac installer has also been updated to Qt5
  • A current development version of libdivecomputer is used for the Windows and Mac builds.
  • A Dive Planner got added again, using the graphical profile editor; it supports different ascent speeds, backgas breaks during deco and many other interesting features; it allows the user to print just the dive plan (without graphic profile); one shortcoming is that currently one cannot re-plan a planned dive, i.e., once you save a dive plan, you can no longer edit / change the plan; you have to start from scratch again. This is on the todo list.
  • Pictures can be associated with dives and shown in the profile.
  • Printing is much improved (but see above), including a “1 dive per page” mode, better rendering of dives (in our mind) and better data presented per dive.
  • Data entry for dives is much more intuitive and consistent.
  • We have a reasonably functional HTML exporter for the dive log (it’s still work in progress but already quite powerful, even though lacking localization support).
  • Support to import dive log files from Seabear dive computers.
  • We added a user survey to learn more about the interests and needs of our users.
  • Improved and extended user manuals
  • New translated user manuals in Spanish and Russian

New in Subsurface 4.1 (May 9, 2014)

  • New:
  • new and improved profile widget with animations, better info box, and a new toolbox to turn on and off many of the additional graphs and information displays
  • improved CVS import and added CVS export
  • import of exported log files from Sensus (CSV) and Shearwater Desktop (XML)
  • improved UDDF and divelogs.de support
  • generalized import dialog
  • much improved consistency for dialog boxes, keyboard shortcuts, etc
  • improved error handling when downloading from divecomputer
  • export an HTML world map with dive sites
  • make backups before overwriting XML files
  • don't display unused cylinders in the equipment tab (this can be turned off and the old behavior restored in the preferences)
  • lots of code cleanup, style fixes, improved consistency
  • improve Qt5 support (but there are still some visual oddities)
  • many improvements to the build infrastructure (out of tree builds, ability to build without Marble, make WIP planner a config option)
  • more than 50 bugs fixed
  • new translation (Greek, British-English, Latvian, and Romanian)
  • experimental "check for updates" feature (mostly for Windows and Mac)
  • experimental undocumented alternative storage format
  • Known bugs:
  • There are a number of small inconsistencies in the UI when editing multiple dives. For example, if multiple dives are edited and some of them already have coordinates set, under certain circumstances the changes aren't saved. To circumvent this bug only edit dives with the same coordinates or edit the dives individually.
  • When using the globe / map widget to edit dive locations, double clicks some times fail to set the correct position.

  • various bug fixes

New in Subsurface 3.0.2 (Mar 4, 2013)

  • This update was mainly triggered by a bug in the handling of pO2 values read from CCR / rebreather dive computers. This bug can lead to incorrect data being stored in the Subsurface XML file. Installing Subsurface 3.0.2 and re-downloading the dives will correct the incorrect data. In order to re-download the dives connect your dive computer (this should only affect people with certain tec dive computers like the Shearwater Petrel or Predator that store pO2 values read from a pO2 sensor in their dive log), open the download dialog, check the box "Force download of all dives" and download your dives. After you save your data file the correct pO2 data should be stored in the samples.
  • If you are using one of those dive computers, have saved data files with Subsurface 3.0 or 3.0.1 and have since deleted those dives from your dive computers, please contact the developers as we also have an experimental script that should be able to fix incorrect XML files - but re-downloading the data is the much more reliable way to address this issue.
  • In addition to this bug fix, 3.0.2 brings a number of other improvements:
  • A Portuguese localization of Subsurface was added.
  • Subsurface now remembers its window size and pane layout the next time it is started.
  • Several importers for data for third party dive software were improved.
  • Dives from the Heinrichs & Weikamp DR5 and from kenozooid can now be imported into Subsurface.
  • A crash with localized versions of Subsurface on Mac was resolved.
  • The map provider for the GPS maps is now configurable.
  • The layout of some dialog boxes was changed to improve usability on small screens.
  • It is now easier to edit date and time of existing dives (and you can now edit duration, maximum and average depth for dives that were manually entered).
  • Several small bugs were addressed.

New in Subsurface 3.0.1 (Feb 27, 2013)

  • Several bug fixes for importing log files from other divelog software; especially imports from DivingLog should work much better now, but we also added new importer functions for UDDF and UDCF.
  • Binary packages for Windows and Mac both had additional issues with importing from other divelogs; those have been addressed
  • Fixes for SAC calculation and gas volume estimates at high pressures (air and nitrox are NOT ideal gases in the physics sense)
  • Added Help link to the online user manual
  • Improved the user manual
  • random other bug fixes
