Changelog — Topical Drift Updates

v2.3 — Concept mode polish + node highlight

Week of Sun Apr 12 – Sat Apr 18, 2026 · Released: 2026-04-18

Concept Mode Map Editor Map Generator UI

Added

Canvas background lightens when a node is clicked — the active neighbourhood stands out against a slightly lighter canvas. Fades back smoothly on panel close.

Improved

BuildConceptParentIndex replaced with AI — more accurate concept hierarchy and parent assignment in generated concept maps.
AI prompts improved to handle edge cases in concept relationship classification.
Text rendering inside circle nodes improved — labels wrap cleanly and scale to fit without overflow.

Fixed

Info box showing wrong value for Concept Type — now displays the correct label for the selected node.
Fit View not working when switching between Topical and Concept modes — re-centres correctly on mode change.
Arrow heads not displaying on edges after switching modes — marker definitions now reload on mode switch.

v2.2 — Concept map pipeline + AI entity classifier

Week of Sun Apr 5 – Sat Apr 11, 2026 · Released: 2026-04-11

Added

Concept map integrated into the generation pipeline — generated automatically alongside topical maps as part of the standard pipeline.

Text placed inside circle nodes in concept mode — labels render inside the circle boundary, scaling to fit.

Improved

Concept map option surfaced in the generator UI — select concept map output directly from generation settings.

Fixed

Concept node type assignments incorrect for entities with ambiguous category membership — AI classifier now resolves these consistently.
