Updates

First release. The installer bundles the OpenSCAD engine, so the 3D view shows the exact rendered mesh — booleans really cut — with nothing else to install. Parts and assemblies, click-two-faces snapping, a parametric vacuum-hardware library, an AI assistant, and a big Examples menu.

The mini window gains Open Folder and New Instance, so you can switch project without leaving the cockpit — and opening a folder now opens its entry point (main.py, or a script named after the folder) so Run works straight away. Also fixes Run in the installed build: interpreter discovery skips the Microsoft Store python.exe placeholder and falls back to registered and standard Python install locations, even when Python was never added to PATH.

Errors now show in red in the Output panel, which reads like a real console — the interpreter, script and working directory are echoed before every run, and a failed Run can no longer be silent. Projects never run in KhervePY's own virtualenv. The mini window shrinks to a real cockpit (Output left, Log right), and KhervePY can now check GitHub for updates and install them.

KherveFitting now updates itself — it checks GitHub Releases, installs the new version silently and reopens, showing a What's New panel filtered to what changed. Export to KherveSheet carries the plot as well as the numbers: series colours, axis ranges and a picture of the figure, with each chart series bound to its own cells and fitted peaks shaded. The 3D waterfall is rebuilt with intensity shading, a floor map, peak tracks, 32 colour ramps and settings that persist, and Sample Manager can replace the spectrum number with a custom sample axis. Fixes: VAMAS import reads the .vms in place and releases the workbook, and F2/F3/F4 image export no longer uses the single-plot size.

ARPES becomes a full workspace — dispersion heatmap on the main plot, constant-energy and Fermi-surface views, two arrow-key crosshairs, 3D cut-away cube and stacked-slice views, Brillouin-zone overlay, and Diamond I05 NeXus / netCDF import. Sample Manager gains .kfit drop-to-merge and insert-plot-as-image, the Tools and Import menus are reorganised per technique, and plot image export size and DPI are now set per kind of plot.

Fixes a crash on a fresh install where opening any file failed with "'MyFrame' object has no attribute 'usage_tracking'". Preference defaults now apply whether or not a config file exists, and a new installation creates its settings from a shipped default configuration on first run.

Note (rich-text) cells and File-attachment cells with inline previews for xlsx, ksheet and kfit; SVG drawing tools with grid and snap that open in KhervePaint; open code in KhervePY and sheets in KherveSheet with reload-on-save; and Help ▸ Report an Issue.

New single-file .kfit project format (much faster for large projects), KherveSheet export, Spectral Denoiser, PCA noise analysis, ARPES import, D-parameter calibration, and per-user settings/library/backups so it works when installed under Program Files.

New Measure menu — scale bar, mm edge rulers, protractor, and a live shape-size readout in mm. Right-click the canvas for tools and the symbol library. The eraser and pencil now edit the pixels of imported images.

Live program output now streams into the Output panel as it happens (python -u). Adds Check requirements.txt to flag & install missing packages, and runs scripts in the project's own virtualenv.

Type directly in the Terminal — the console is editable in place, like a real shell. New KPy icon, rendered natively at every size.

NIST XPS binding-energy database viewer.

A Jupyter-inspired computational notebook as a native desktop app.

Hideable AI assistant sidebar grounded in the active document.

AI panel on by default with a toolbar toggle; equation-editor slot UX.

An Excel-inspired spreadsheet workbench for scientific data.

Fixed a Windows encoding crash in git/pip output, themed folder icons.

Hybrid raster + vector drawing for scientific figures.
