- Nov 9, 2026 1.15.0- Another new leg agreement algorithm "Slope-corrected angular deltas" that ought to solve issues with taking repeated readings on steep legs while remaining close in spirit to BCRA Grade 5; testing and feedback welcome (#321) - Splays can now be marked as going to another feature, such as a stal. Survex ... is imported as another feature. Older versions of SexyTopo open these as ordinary splays to a wall (thanks Andrew Atkinson) - Splays can be disabled from the leg menu or the edit dialog to hide readings (for calibration checks for example). Disabled splays are crossed out in the table, hidden in sketches, and dropped or commented out in file exports (thanks Andrew Atkinson). - Fix Survex and Therion import of legs that were shot backwards, which were placed in the opposite direction (thanks Andrew Atkinson) - Fix promoting a splay onto a leg that was shot backwards, which turned the leg round and added the splay in the wrong direction (thanks Andrew Atkinson) - Fix splays restored from a promoted leg being listed the wrong way round in the table (thanks Andrew Atkinson) - Fix editing a leg averaged from several shots, such as renaming one of its stations, which replaced the shots with their average. The shots are now kept unless the readings themselves are changed (thanks Andrew Atkinson) - Fix leg and station comments added from the menu not being treated as an unsaved change (thanks Andrew Atkinson) - Survex export now writes ISO dates (2026-01-05), which needs Survex 1.4.13 or later; Therion keeps 2026.01.05. Importing either accepts year-month-day dates separated by ".", "/" or "-" (thanks Andrew Atkinson) - New flowstone symbol, exported to Therion as a flowstone point
