Some of the changes since Subsurface 4.2
+Subsurface now supports flexible filtering of the dive list. 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 (see image below)
+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. (See image below)
+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 Suuntu 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. Here is a dive profile for a Poseidon MkVI:
+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 +
+
+
Known bugs
-
+
-
+
+There appears to be a bug in Qt: when changing the password needed + authenticate with a proxy, Subsurface will not use the new password + until after a restart +
+
+
Subsurface 4.2
+The Subsurface developer team is proud to announce the release of the +next update of Subsurface.
Subsurface is an open source divelog program that runs on Windows, Mac +and Linux.
With Subsurface the user can download dive information directly from a +large number of supported dive computers. Subsurface is able to track +single- and multi-tank dives using air, Nitrox or TriMix. It displays +a dive profile with all related information including air consumption +and alarms. It also allows logging of information like weights and +exposure protection used, dive masters and dive buddies, and enables +the user to rate dives and provide additional dive notes.
With Subsurface the user can track dive locations including GPS +coordinates (which can also be conveniently entered using a map +interface). Subsurface calculates a wide variety of statistics of the +user’s diving and keeps track of information like the user’s SAC rate, +partial pressures of O2, N2 and He, calculated deco information, and +many more.
Subsurface allows the user to print out a detailed log book including +dive profiles and other relevant information. The program is localized +in about 20 languages and well supported by an active developer +community. This community also made new and shiny offline manuals in +Spanish and Russian possible.
One of the major strengths of Subsurface is its support of a wide range +of dive computers (most common dive computers are supported with the help +of libdivecomputer); a detailed list is in the SupportedDivecomputers.txt +file. Subsurface can also import existing dive logs from several sources +including MacDive, Suunto DM3/DM4, JDiveLog and divelogs.de. Another +strength is its ability to visualize the depth profile (and, if +available, the tank pressure curve) in very innovative ways that give +the user additional information on relative velocity (and momentary +air consumption) during the dive through the coloring of the graphs.
Some of the changes since 4.1
-
+
-
+
+The Windows installer is now a 64bit installer including Qt5 +
+
+ -
+
+There is still a deprecated 32bit installer including Qt4, but that has + several known issues (among others, printing has a number of bugs that + were fixed in Qt5). +
+
+ -
+
+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 + out users +
+
+ -
+
+improved and extended user manuals +
+
+ -
+
+new translated user manuals in Spanish and Russian +
+
+
Known issues:
-
+
-
+
+(Windows specific) Many Windows fonts don’t support specific characters, + specifically subscript "2" (eg in pO₂). New installations of Subsurface + will automatically pick a font that contains this character, but if you + had Subsurface installed on a specific system before, it likely has + saved the previous font in its settings. In that case the best solution + is to manually change the font to one that contains this character, + e.g. Calibri. +
+
+ -
+
+(Windows specific) When upgrading from Subsurface 4.1, after saving of a + logfile the logfile’s name may be listed a second time in the files menu + because of a change in the representation of logfiles filename in the + Windows registry. +
+
+ -
+
+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. +
+
+ -
+
+(Windows specific - only 64bit) If an ad blocker is used and set to + offline mode, the manual check for an update crashes Subsurface. +
+
+ -
+
+When using the globe / map widget to edit dive locations, double clicks + some times fail to set the correct position. +
+
+ -
+
+Sometimes the globe will show the same pane several times. Try to zoom + in or out of the location and give the system time to download the map + tiles in the background - on slower network connections this can take a + while. +
+
+
New in version 4.1 (compared to Subsurface 4.0.3):
+-
+
-
+
+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 +

+
+ -
+
+enable https in Windows binaries +
+
+
New in version 4.0 (compared to Subsurface 3.1):
+With version 4.0 the Subsurface team switched to a different UI +toolkit. This caused the need to do a complete rewrite of a large +chunk of the Subsurface code base. We decided to keep much of the +logic and core of the existing code around, but used the opportunity +for quite a bit of cleanup and many improvements.
The basic concepts are the same, most of the basic features are the +same, but trying to create a concise list of changes that summarizes +the more than 1600 commits that have gone in since version 3.1 seems a +daunting task.
Here are some of the highlights:
-
+
-
+
+new map widget with a spinning globe to visualize dive locations +
+
+ -
+
+much more "native" look and feel under Windows and Mac +
+
+ -
+
+ability to edit dives "in place": simply click on an entry in the + Dive Notes or Equipment tabs to start editing +
+
+ -
+
+more data about each dive is presented in the Dive Notes and can + be edited without separate dialogs and without having to go through + context menues +
+
+ -
+
+graphical editor for dive profiles for manually added dives +
+
+ -
+
+better information overlay for the dive profile +
+
+ -
+
+addition of a "ruler" tool in the profile window that allows + measuring of many properties between two points in the profile +
+
+ -
+
+better tag system with both predefined user-specified free text tags +
+
+ -
+
+better integration with divelogs.de (upload & download support) +
+
+ -
+
+ability to show the user manual from within the application without + a life internet connection and without opening the manual in an + external browser window +
+
+ -
+
+better statistics (with per-trip statistics available) +
+
+
Known issues:
-
+
-
+
+Filter→Select Events is not implemented +
+
+ -
+
+Dive planner has been disabled for now +
+
+ -
+
+https support for divelogs.de on Windows is disabled +
+
+
New in version 3.1 (compared to Subsurface 3.0.2):
+-
+
-
+
+track tags for dives (things like boat, shore, deep, etc) +
+
+ -
+
+enable filtering by tags +
+
+ -
+
+ability to modify events from a context menu in the dive profile + (this includes the ability to add gaschange events) +
+
+ -
+
+direct export / upload to the divelogs.de online logbook +
+
+ -
+
+import of Suunto DM4 files +
+
+ -
+

+
+ -
+
+dive planning: add option for last stop at 6m/20ft +
+
+ -
+
+added support for Heinrichs Weikamp OSTC3 and Suunto DX +
+
+ -
+
+native support for the Shearwater Petrel (much faster download) +
+
+ -
+
+various bug fixes +
+
+
New in version 3.0.2 (compared to Subsurface 3.0.1):
+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 version 3.0.1 (compared to Subsurface 3.0):
+-
+
-
+
+Several bug fixes for importing log files from other divelog software; + especially imports from DivingLog should work much better now, but + also new importer functions for UDDF and UDCF +
+
+ -
+
+Fixes for SAC calculation and gas volume estimates at high pressures + (air and nitrox are NOT ideal gases in the physics sense) +
