 Version History

Version 8.3.1 — 2023.12.18

• FIXED: A bug that would cause FaultKin to crash on Windows or Linux when a row of data was selected in the listbox (Thanks, Ali!). There are no new features or fixes for the Mac version but it has been updated to this version number as well.

Version 8.3.0 — 2023.11.09

• The Mac Version now uses an Apple Maps satellite view for showing the location of your data. This view is provided for free to Mac programs but cannot be used on any other platform. The Google Maps images that I was using in earlier versions of the program are no longer freely available to programers so the Map Tab has been eliminated from both Windows and Linux versions. Sorry!

• The Mac version is now a universal binary, meaning the it will run natively on either the new M-series Macs or on older Intel-based Macs.

• Swath profiles constructed (usually from earthquake data) can now be saved or copied to clipboard in PDF format.

• The User manual has been updated with the new functionality related to the Map View (Mac only).

Version 8.1.2 — 2019.12.12

• Fixed a bug in the Rotation dialog that could cause a crash.

Version 8.1.1 — 2019.10.18  (the “PDFs FINALLY work” release!)

• Fixes some bugs with printing.

• Page Setup is now separate from Print. You only need to do page setup once.

Version 8.1.0 — 2019.10.10  (the “PDFs FINALLY work” release!)

• Robust new PDF engine. Saved PDFs are now way more compatible and open polygons (essentially any great or small circle) are saved to the pdf as a single open path rather than unconnected line segments making manipulating the PDF in a graphics program much easier.

• When the Plot Pane has the focus, you can use Edit>Copy to copy the graphic to the clipboard as a PDF (cropped to the szie of the graphic). You can then paste the graphic directly into any modern vector graphics, word processing, or presentation software that can accept PDF data on the clipboard.

• The Mac version is now distributed as an Apple Installer package that has been hardened and notarized by Apple so that it will work in Mac OS Catalina (10.15).

• Cosmetic changes to arrow symbols

• Bug fixes...

Version 8.0.7 — 2018.12.17

• Checkbox in Inspector palette enables the plotting of the average of multiple measures of the same event rather than just plotting all of them

• Added a “Find in any Field” command to quickly search and select all instances of the entered text snippet in any field

• Fixed batch annotation errors pertaining to seismic moments

• Streamlined various selection routines.

Version 8.0.5 — 2018.12.11

• Numerous improvements to the Map Tab interactivity (Mac only). See revised manual for how these work in detail

  • measure distances by holding down the Control Key

  • select a group of data points on the map by holding down the Shift Key

  • Construct a swath profile by holding down the Option Key

    • You can select points on the swath profile by holding down the Shift Key while clicking and dragging

    • You can save the swath profile (especially useful for analyzing earthquake data) as a text file

• Revised manual describes in detail the Map Tab functionality

• Corrected a bug that would cause the program to crash when saving as PDF (thanks, Jonathan!)

Version 8.0.0 — 2018.11.14

• Upload to your StraboSpot account with calculated P&T axes as tensors in the spot

• Batch annotation of selected faults

• Updated manual

• Revamped map Window is vastly more functional on the Mac but, sadly, not on Windows. [Mapping is considerably more of a drama now that Google requires registration and charges for static map hits. This required going to a simpler embedded map, and graphic overlays on embedded maps do not work in Windows, unfortunately…]

  • Show as many faults as you want

  • Visualize elevation and magnitude with color and point size, respectively

  • Plot beach balls on the map for N <= 100

  • Read latitude and longitude of the cursor within the window

• New internal data architecture should improve stability once the bugs are ironed out, especially when it comes to deleting datums and sorting

• the Windows versions now come wrapped in a real Windows installer program which will put everything where it is supposed to go on your system!

• support for “Dark Mode” on OS X Mojave
