// _Subsurface_ 4.7.5 Release Notes _Subsurface_ 4.7.5 - Month dd, 2017 ------------------------------------------ Some of the changes since _Subsurface_ 4.7.4 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - Limit min. GFlow to 10 and min. GFhigh to 40 in preferences for profile and planner - Fix issues related to debug logging on Windows - Add "Bluetooth mode" in the BT selection dialog: Auto, LE, Classical - Correct display of cylinder pressures for merged dives - Allow user defined cylinders as default in preferences (#821) - mobile: fix black/white switch in splash screen (#531) - UI: tag editing. Comma entry shows all tags (again) (#605) - mobile: enable auto completion for dive site entry (#546) - Printing: the bundled templates are now read-only and are always overwritten by the application. The first time the user runs this update, backup files of the previous templates would be created. (#847). Some of the changes since _Subsurface_ 4.7.2 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - Small UI fixes - Improvement to oxygen breaks code in planner - Write log messages into files when not started from a console on Windows - 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. - Improve calculation of VPM-B decompression ceiling displayed in profile. In 4.7.2 the VPM-B ceiling was generally under-estimated for decompression dives and could be grossly over-estimated for what were actually no-decompression dives. Some of the changes since _Subsurface_ 4.7.1 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - 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 - Change to a more consistent way to show errors in Subsurface - Solve several potential issues with the cloud account authentication flow - Fix a potential problem when saving data that was loaded from a git repository into cloud storage - 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) Some of the changes since _Subsurface_ 4.6.4 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - 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. - New map widget. No more rotating globe, but much better support for the underlying widget - so overall an improvement. - Many small UI fixes - 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. - 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 due to changes of bottom time by one minute or depth by 1m? - Faster planning for long decompression times - Option in user preferences to display units in main dive list table - Show green tank change icon when switching to EAN100 - Better support for importing dive data from Shearwater desktop, DL7, Datatrak and other 3rd party formats. - Support for OSTC 4 configuration - Updated Facebook support to use a newer, still actively supported API. - Many bug fixes - Added 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 Some of the changes since _Subsurface_ 4.6.3 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - Allow direct entry of dive depth and duration for manually added dives - Improved table labels and tooltips in planner - Minimum gas calculation mode in planner - Better handling of notes when replanning dives - Many consistency changes for the terms used across the application - Support border width setting in printing templates - Fix situations in which cylinder pressures would incorrectly be marked in red - Many improvemens to CSV export and import - Small fixes to DivingLog import - Attempt to parse dive logs as Latin-1 if uft-8 parsing fails - Add support for importing latest Suunto DM5 format - Correctly sync unit system between Subsurface and Subsurface-mobile (using cloud storage) - Fix several rounding related problems - Fix several potential crashes - Better handling of Uwatec memomouse tank pressure values - Better handling of Cobalt imports with unused tanks - libdivecomputer: - fix bug in Subsurface version of libdivecomputer that could cause buffer overflow - several small bugfixes from upstream libdivecomputer Subsurface-mobile: - Fix problems with the app showing the wrong dive in the details view, both when tapping on a dive in the dive list, and when rotating the phone - Fix problem with map display when running the app in a non-English locale. We now send decimal GPS coordinates to Google Maps - Switch to Kirigami 2 - Fix numerous small UI issues around editing and adding dives. Some of the changes since _Subsurface_ 4.6.2 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - Fix cloud storage access for users with non-ASCII paths on Windows - Allow using ctrl-scrollwheel to scale the font size of dive plan notes both in the UI and when printing - Ensure that keyboard shortcuts via Ctrl/Cmd work in localized versions of Subsurface - Improve a number of UI strings for consistency and typos - Make sure column labels for cylinder table get translated - Improve dive merging: deal with water temperature, better handling of dive sites - Fix typo in saturation / desaturation rates used in Buehlmann calculations; this has a small impact on some dive plan deco times - Improve some icons used in Preferences dialog - Fix CSV export of weights in lbs - Various small fixes - Massive improvements for several of the translations - Update Russian user manual - Add Catalan translation Some of the changes since _Subsurface_ 4.6.1 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - Planner: update altitude limits with unit change - Fix potential crash when merging dives - Handle dive dates before 1970 correctly - Include geo location when exporting to divelogs.de - Add credits button to about screen - Many updated translations (and add Greek as partially supported language) Some of the changes since _Subsurface_ 4.6 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - Fix problems with incomplete localization in Windows builds - Fix Seabear import issues - Prevent double click on dive number in dive list from (temporarily) editing dive number - Improve cylinder handling when merging dives - Store a few more preferences in the cloud storage so we can match certain aspects of the profile configuration in Subsurface-mobile - Fix scaling issue that prevent the visual dive editor from reaching certain dive durations - Many fixes and improvements in the dive planner: - Fix uninitialized variable that could cause odd problems in the planner when the dive list was empty - Changed VPM-B calculation for repetitive dives: Resets the maximum crushing pressures and the maximal ambient pressure between repetitive dives to prevent anomalies that a dive produces a shorter deco when following another one than without - Allow the user to disable tanks while planning dives (this makes it much easier to evaluate different scenarios) - Re-enable ctrl-click to remove remaining dive points in planner - Improve printed dive plan (no more 0-length segments at gas changes) - Print additional information with the dive plan (assumed SAC values, altiude) - Fixes for dive computer support and new dive computer support (through the great work of libdivecomputer) - add support for Aqualung i450T, i550, and i750TC - add support for Cressi Drake - add support for Hollis DG02 - add support for Oceanic F10 - fixes for Hollis DG03 Some of the changes since _Subsurface_ 4.6 Beta 2 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - Many updates and improvements to the user mannual - Many translation updates - Improved OSTC 4 support - Bugfix for parsing AP Divesight dive log - Fix deco algorithm confusion between planner and log - Display surface interval in planner Some of the changes since _Subsurface_ 4.6 Beta 1 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - Add support for importing Underwater Technologies AV1 log files - Fixed problems posting to Facebook - Fixed problems opening pictures from picture tab - Improvements to OSTC firmware update handling - Small improvements to dive planner (show repetitive dives) - Fix surface pressure in dive planner - Updated Windows and Mac binaries to Qt 5.7.1 (and newer versions of several other support libraries). Some of the changes since _Subsurface_ 4.5.6 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - Fixed spurious errors when saving to cloud storage - Better handling of slow network connections when using cloud storage - Add --cloud-timeout= command line argument that allows to wait longer (or shorter, for that matter) before we time out waiting for cloud storage. Very useful when in areas with poor internet connectivity - Add --user= command line argument that allows switching between different users from the command line - Many fixes to CVS importer - DAN DL7 import - SmartTrack .slg import - Fixes to Divelogs.de import and export - Fixes to UDDF exporter - Small fix to Uemis downloader for yet another corner case (Uemis downloader is known to be broken for some users - it is no longer actively maintained) - Improved handling of dive computer events (grouping them into info, warning and alert - best supported on Suunto EON Steel) - Add heatmap visualization of deco tissue loading - Many small fixes to the dive planner - Many fixes for various errors - Added support for additional divecomputers - aqualand: Citizen Hyper Aqualand - meridian: Scubapro Mantis - nitekq: Dive Rite NiTek Q, NikTek Trio - Aeris: 500 AI, XR-1 NX - Aqualung: i300, i550T - Beuchat: Mundial 2, Mundial 3, Voyager 2G - Cressi: Giotto - Hollis: TX1 - Mares: Airlab, Smart Apnea, Puck 2 - Oceanic: OCi - Scubapro: XTender 5 - Sherwood: Amphos, Amphos Air, Vision - Subgear: XP-3G, XP-Air - Uwatec: Aladin 2G Some of the changes since _Subsurface_ 4.5.5 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - Fix crash when downloading from Bluetooth based dive computers - Small fixes to VPM-B ceiling calculations - Import picture URLs from divelogs.de - Add support for the new version of the Suunto DX - Don't get caught in endless loop of git authentication errors - Fix time parsing of Divesoft Freedom - Support DAN DL7 import Some of the changes since _Subsurface_ 4.5.4 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - Update to latest libdivecomputer which adds support for Cochran Commander and EMC, Uwatec Aladin Sport, Suunto Zoop/Vyper Novo, Suunto D4i and D6i with latest firmware, Heinrichs & Weikamp OSTC4, Aqualung i450T and Cressi Newton. - In the dive planner, switch pressure unit when planning in recreational mode and setting a tank reserve - In the dive planner, show the correct VPM-B + conservatism on the profile when planning in VPM-B mode and show the planner specific gradient factors in Bühlman mode. - Enable showing a VPM-B based "ceiling" on the profile - Fix bug regarding depth parameter in OSTC/OSTC3 configuration - Fix bug in CSV export - Fix bugs in Suunto DM5 import - Fix potential race when immediately switching to Add dive or Planner while accessing cloud storage - Fix issue for some users with cloud storage passwords Some of the changes since _Subsurface_ 4.5.3 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - Update to latest libdivecomputer to fix a number of issues in the parsing of dive computer data (Shearmos Amphos Air, Shearwater Predator, several Oceanic models) - Add support for Oceanic / Aeris F11, DiveSystem iX3M, Shearwater Perdix - Fix several issues with imports from CSV, divelogs.de and other sources - Add better support for OSTC3 configuration - Fix potential rounding error when exporting weight systems - If XML file contains actual salinity (instead of the density value that we call salinity), correctly interpret that value - Add statistics by dive type - Small UI fixes Some of the changes since _Subsurface_ 4.5.2 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - Fix confusing warning about different number of tanks and gases on some Suunto dive computers - Fix missing temperatures on some Suunto dive computers - Fix several corner cases in the Uemis support - Fix a few random UI inconsistencies (UI elements not being cleared / removed / reset in certain circumstances) - Cloud storage: no longer store picture binary data in the Subsurface cloud storage - this can cause excessively long sync times - When matching dive site names when entering a location name, match anywhere in the location name, not just from the beginning (this makes it much easier to find existing dive locations if you remember only part of the name) - Some fixes for importing data from other formats - English user manual has been updated for language consistency and readability Some of the changes since _Subsurface_ 4.5.1 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - No code changes to Subsurface, just an update to libdivecomputer and new binaries on all platforms. Some of the changes since _Subsurface_ 4.5 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - Subsurface no longer crashes on Windows when run in the German localization and using the planner - avoid a situation in the planner where the user ends up with no usable cylinder when trying to create a plan - work around an issue where in some environments the user wasn't able to edit the existing print templates (and no error was shown, the edits were just silently ignored) - link against hidapi if it exists; this is required to add support for the Suunto EON Steel on Mac when using the matching version of libdivecomputer - get tank sizes from Suunto EON Steel (using the matching version of libdivecomputer) - increase cloud storage timeout to increase the chance that this works on very poor internet connections (which appear to be rather typical for great dive locations) - mention the Shearwater Nerd as supported computer (should be identical to the Petrel 2) - some more adjustments to better suit the needs of freedivers - fix problem with Uemis downloader on Ubuntu - fix algorithm to calculate the picture time shift based on a picture of the time displayed on a dive computer - fix incorrect sample depth when dive computer sends samples without depth (instead these samples now get interpolated) - fix visualization of SAC rates that had some issues in certain corner cases - fix UI issue on Mac where selecting a location with enter/return did not result in the expected behavior - fix upload of dives to divelogs.de on Windows - change divelogs.de export to match the import behavior when it comes to splitting dive location and dive site Some of the changes since _Subsurface_ 4.4.2 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - 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 and authenticate with the same email address and password as set up in _Subsurface_. - Dive site handling. + Dive sites are now a first class citizen in _Subsurface_ and can be managed as such. Dives include a reference to a dive site. This also caused changes to our file format (and we bumped the file format version to 3). On first open old data files will be backed up and converted to the new format. - Geo taxonomy. + A web lookup service has been implemented that allows the user to get geo taxonomy data based on a GPS fix - so for a dive site that contains GPS data _Subsurface_ can look up the closest body of water, the country or closest city. - Significantly improved print support. + Printing is now template driven and allows the user to customize the format in which dives are presented in print. - Better Bluetooth device support. + Instead of having to manually set up BT devices in the OS, _Subsurface_ now has a much more intuitive UI that allows the user to work with BT dive computers. - VPM-B support for dive planning. + The dive planner module in _Subsurface_ now offers a choice of deco algorithms with both Bühlmann ZH16 and VPM-B. The VPM-B implementation is new and has been developed from scratch. We have tested this against a number of known good profiles from the Fortran reference code but would certainly recommend a bit of extra caution when using it for dive planning. - Recreational mode for dive planning + A new planner mode for dives within no decompression limits using a single ascent gas. This mode computes the remaining bottom time for a diver that avoids mandantory decompression stops and stays within the given amount of gas. This is a natural extension of non-decompression dive tables and aids like the RDP. - Better support for freediving. + The dive list context menu now allows the user to split a dive into multiple dives at a surface interval. If the dive computer reports "free dive" mode the split(s) happen at every surface interval of at least 10 seconds, otherwise the threshold is 60 seconds. - Improved image import and management, + _Subsurface_ now does a better job when handling changes in image folder location and can add images from URLs instead of just local files. - Undo / redo support. + While this does not cover all operations, yet, many operations can now been un-done and subsequently re-done. - Many fixes and improvements for import third part files and CSV files - Ability to load dives exported with OSTCTools - Support for more GPS coordinate formats - Fix SAC rate calculation for dive computers reporting samples after the diver reached the surface - Don't zoom out the globe to "sky view" when a dive site has no GPS data - Various other small fixes Some of the changes since _Subsurface_ 4.4.1 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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 Known issues (and this was the case in 4.4 and 4.4.1 as well): Suunto Eon Steel support on MacOS is currently not working as MacOS grabs the device before Subsurface gets to see it. Some of the changes since _Subsurface_ 4.4 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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. 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. image::images/subsurface-dive-computer1.png["Subsurface divecomputer download dialog",align="center"] 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. image::images/subsurface-csv.png["Subsurface csv import dialog",align="center"] _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. We added support for importing logs from the Divesoft Freedom We went back to a single, Qt5 based 32bit binary that works on all versions of Windows, 32 or 64bit, all the way back to Windows XP. Some of the changes since _Subsurface_ 4.2 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ _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 (see the panel below the main menu in the image below) image::images/V4.3_Subsurface_filter.jpg["Subsurface panel",align="center"] 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) image::images/V4.3_CylBars.jpg["Cylinder bars and tissue saturation graph",align="center"] 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. Here is a dive profile for a Poseidon MkVI: image::images/V4.3_CCR.jpg["CCR dive profile",align="center"] *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 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 - improved CSV import and added CSV 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 New in version 4.0.3 (compared to _Subsurface_ 4.0.2): ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - fixed unitinialized variable bug that caused errors downloading from divecomputers New in version 4.0.2 (compared to _Subsurface_ 4.0.1): ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - fixed potential crash when importing dive data without dive computer model information - improve parsing of equipment data; this now accepts localized units as well as input in units that are not the display units (so if you run _Subsurface_ in metric, but went diving in a place where weights are in US Pounds (lbs), you can now enter the weight in lbs and _Subsurface_ does the right thing) - fix temperature conversion when downloading data from Uemis SDA - improve autocompletion to always be case insensitive - improve selection handling in the dive list - include event data in libdivecomputer dump - improve profiles generated for dives with no depth samples and no average depth New in version 4.0.1 (compared to _Subsurface_ 4.0): ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - fixed several bugs handling non-ASCII text both in dive info text fields as well as in Windows file names - added support for generating libdivecomputer log and dump files - many improvements for import and export of other file formats - XSLT files are built-in as resources, avoiding issues with not finding them - support more GPS coordinate formats - fixed several bugs around editing of manually entered dives - fixed several bugs with entering data for weights and tanks - increase the number of tracked weight systems to 6 - fixed font setting in preferences - improved look and feel when running dark themes - support older versions of Mac OS/X with default DMG (>= 10.5) - 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 - improved printout formatting and printer dialog - support for color printing - 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) - Added Help link to the online user manual - Improved the user manual - random other bug fixes New in version 3.0 (compared to _Subsurface_ 2.1): ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - Many new divecomputers supported, bugfixes for existing divecomputers - Cressi Leonardo, Seemann XP5, Mares Matrix, Mares Puck Pro, Mares Nemo Wide 2, Shearwater Petrel, Shearwater Predator, Aeris A300 AI, Hollis DG03 - significant improvements for the Heinrichs Weiskamp OSTC - Significantly improved selection of divecomputers for direct download - Map display of GPS locations of dives and ability to enter and edit those - Improved automatic dive numbering - Data overlay for profile plot (with additional statistics information) - Zoom function for profile plot - Dive planner - Improved printing support - Improved dive trip handling - Support for downloading dives from multiple computers (so for example both your main and your backup computer) - Added ability to import existing divelogs from Suunto DM3 (no manual unpacking needed anymore), MacDive and divelogs.de - Lots of features to make tec divers happy: - Experimental deco calculation with optional display of a calculated ceiling (Buhlmann ZH16 with gradient factors) - Display of deco information from some divecomputers that support this - TriMix support - CCR support (fixed or variable setpoint, on dive computers that support this) - Optional pO₂, pN₂ and pHe graphs - CNS tracking for supported divecomputers - Lots of bug fixes
