Release Notes
This section records major implementation changes, evaluation notes, and technical decisions behind GeoSignal Preview.
Versions v0.1 through v0.4 are historical milestones reconstructed from the repository commit history. Detailed benchmark artifacts were not preserved for every early version, so these pages describe only changes supported by the source history. v0.5 and later include the more detailed evaluation records created during development.
General visitors can read Home, Demo, and Method first. These notes are mainly for readers who want to understand how the preview evolved across versions.
Versions
| Version | Main Focus |
|---|---|
| v0.1 | Initial CLI and SVRF-like geometry-rule experiments |
| v0.2 | Flask web prototype and layout preview |
| v0.3 | Modular geometry engine, width/space analysis, and density |
| v0.4 | Raster, Abbe imaging, contours, and hotspot evaluation |
| v0.5 | Selectable pya backend comparison beside the existing gdstk path |
| v0.6 | pya-native geometry path, candidate overview update, and printed metric refinement |
| v0.7 | Combined review GDS, candidate-specific contours, and bounded-memory imaging |
| v0.8 | Focus/dose process-window analysis, calibration, and PW artifacts |
| v0.8.1 | Backend-neutral imaging contract and focus/dose performance refactor |
| v0.9 | Exact Hopkins/TCC/SOCS cross-validation and bounded optical-mode caching |
| v0.10 | CD/area ranking, relative-dose fitting, source/pixel/ambit/DBU validation and result artifacts |
v0.8.0, v0.8.1, and v0.9.0 are tagged application releases. v0.9.0 retains Abbe as the public service default.
Reading Guide
Home, Demo and Method explain the workflow and interpretation; release notes collect version-specific evidence:
Home / Demo / Method
-> what the preview is
-> what the images show
-> how to interpret the result
Release Notes
-> why implementation choices changed
-> what was compared
-> what remains limited
The notes below are technical records. They are not required to understand the live demo.
