19-Feb-2019
- Fixed bug that caused application to crash if adding a single time log to an empty survey.
18-Feb-2019
- Resolved issue with several DepthAxis views being shown when loading files with several depth channels(e.g DEPTH and DEPT). Now each survey will have only one depth axis called “Depth”.This will crash the application if loading an older LV1 which contains a Depth Axis called “DEPT”.

23-Jul-2018
- Added additional decimals to the stretch factor line-edit to avoid effects of round off errors when re-applying a stretch-factor
22-Jul-2018
- The stretch and shift parameters in LogFile Properties were always in US number format regardles of application settings. This gave undefined results when typing in european number format.

10-Jul-2018
- Refactored DLIS conversion code. Added MNEN filter
9-Jul-2018
- Previous issues parsing DLIS files turned out to originate from the lack of suppot for multi-dimensional arrays. This has now been implemented for 2 dimensions (i.e data channels containing an [m]x[n] matrix).
4-Jul-2018
- Added ability to ignore parse-errors when converting DLIS files where the estimated FDATA length differes from the actual length of the IFLR data. This is a quick-fix and doesn’t address the underlying problem as to why the length differs(probably software bug)
19-Jun-2018
- Fixed bug in LAS Import that resulted incorrect parsing if CurveInfo header contained an empty line
1-May-2018
- DLIS converter/browser will now parse DLIS files with Set Type = AXIS

- Interpretation zones table has been changed to generic zones table(as used by perf/prod)
- Added extra digit on depth scale at high zoom factors to avoid equal depth values
2-Apr-2018
- Fixed a bug with the way the depth distance between samples was calculated. The previous method introduced round-off errors in the result which in turn resulted in incorrect indices to be calculated when calculating the sample index at a given depth.
27-Mar-2018
- Made size of dialogs independent on screen resolution(by using fractions of screen size as width/height instead of absolute number of pixels)
- Improved curve trackers with a cursor and higher contrast background
26-Mar-2018
- Perforations are now ordered by depth both compared to other perforations and the From/To depth
- Added “Curve Tracking Mode” where the values of the currently selected log-pass curves will be shown on each data view at the cursor depth.
24-Feb-2018
- Added support for DLIS files containing 440-CHANNEL(Schlumerger) LABELS of type “MULTI_INSTANCE_RAW_NAME”
2-Feb-2018
- When all dataviews are removed from a column window the Z and depth view widgets are now hidden so only a white screen is shown
- Settings unit is used for depth shift parameter
- MFC Cross Plot now shows diameters instead of radius. Diameters are calculated as the sum of two opposing finger readings
- The NULL value from the LAS file header is now used to determine the invalid value(usually -999.25)

- Optimized floating point formating when converting to strings
- Fixed a big where the application would crash if all data was deleted from a non-visible survey
26-Nov-2017
- Added option to switch between MFC dataview drawing modes (icon next to settings)
- Floating point number format selection has been implemented throughout application. Including depth view and delta tool.
23-Nov-2017
- Changed MFC Dataview mode to increase the width of the individual finger curves thereby increasing detail. Each finger will not have it’s own space anymore. In future versions it may be possible for the user to switch between modes.
22-Nov-2017
- Polished the Mulfifinger Caliper Data View. It now ensures that finger readings do not extend beyond the width of the data view (auto scaling) and shows the finger index in the data view scale.
- Now generates unique names for each MFC data view in survey (allows for multiple MFC DVs in each survey. Still some weird bug with only updating one 3D view when scrolling)
- Each MFC DV scale will contain the applicable logpass filename
21-Nov-2017
- Optimized depth marker annotation so that redraws only takes around 25% of the previously required time
15-Nov-2017
- Fixed bug that would crash the application if loading an lv1 file without any surveys
- Corrected misc. issues in the Well Details dialog(sorting of depth markers, 2 instead of 1 decimal in depth marker depths)

- Added blue semi-transparent rectangle when zooming
- Fixed bug that lead to application crash when selecting properties for an empty User DataView
8-Nov-2017
- Fixed bugs in DLIS conversion (unable to convert ASCII to Floating Point)
- Implemented Multifinger Caliper Settings tab in Global Settings. It is now possible to control which MNEMs will trigger an MFC dataview generation
7-Nov-2017
- Changed the scale widget so that line, MNEM and actual scale values will be removed (in that order) if the scale widget is too narrow (to avoid drawing on top of each other)
- Fixed bug in curve renderer that, under special conditions, would result in selecting the incorrect processed/optimized curve. This would lead to the introduction of infinities in the rendered curve and very slow rendering speeds
1-Nov-2017
- Made slight adjustment to icon positions
- Fixed bug with data browser not updating the data channels in UserDataViews when loading files
- Copy of table data only copies selected rown and columns
