v3.1.0

[vagkaratzas]

Added

• Network upload accepts a minimal 2-column edgelist (SourceNode, TargetNode only) — all nodes are spread out in a single default layer named Layer1. The optional Weight and Channel columns still apply. A downloadable example lives in the Help → Examples tab.

• Edge weight can now be shown as edge thickness, not only opacity. The Edge Actions panel replaces the "Edge Opacity By Weight" checkbox with a "Show Edge Weight As" radio — Nothing / Opacity / Width / Both — plus intra- and inter-layer width sliders for whichever property weight isn't driving. Sessions carry the choice as the independent edgeOpacityByWeight and edgeWidthByWeight booleans; files written before this default to opacity, so they render unchanged. Thickness needed Line2 (instanced quads) because WebGL renders every line primitive at exactly 1px regardless of linewidth.

Changed

• Channel curvature sliders reach much further — intra-layer 10–60 (was 10–20), inter-layer 1–30 (was 1–10) — so the channels of a multi-channel edge can be pulled well apart instead of running nearly parallel. Defaults are unchanged, so existing sessions render exactly as before.

Fixed

• Edges no longer glow. Thick edges cover a large share of the screen, and bloom on all of them was blinding against dark backgrounds. Bloom is now selective (three's off-screen bloom-composer pattern) and reads from node spheres alone, so nodes still glow, edges and layer planes stay crisp, and the extra pass costs a few spheres rather than a second full scene.
• Curved channel edges rendered as dotted lines with beads at the curve points once thickness landed. LineMaterial's worldUnits mode assumes a perspective camera — its fragment shader traces a view ray from the camera origin and discards anything farther than half a width from the segment, which under this app's orthographic camera discards along the whole segment. Widths are now screen-space, sized against a shared resolution uniform kept on the frustum size (so the numbers still mean world units), retargeted on resize and for the PNG export.
• Node colors rendered washed out/dark in the 3D scene compared to the 2D navigator. The bloom composer was blitting linear color straight to the sRGB canvas (missing OutputPass), and the ambient light was left at the pre-r155 intensity that physical lighting divides by PI.

Backend dependencies updated to latest via uv lock --upgrade; transitives moved with them (notably starlette 1.3.1 → 1.6.0 and websockets 16.0 → 17.0.1). No known vulnerabilities on either side. pydantic-core stays at 2.46.4 — pydantic pins it exactly. TypeScript stays on 6.0.3: 7.0.2 typechecks fine but typescript-eslint 8.x refuses to load against the TS 7 API, so linting breaks; revisit once typescript-eslint ships TS >=7.1 support. CI now runs uv sync --frozen so it installs exactly the locked set the Docker image ships.
