Changelog

All notable changes to local_chemillusion are documented here. This project
adheres to Semantic Versioning and the Moodle plugin
versioning convention (version.php).

Unreleased

Added

• GitHub Actions CI (Moodle Plugin CI on 4.3/4.5) and release packaging workflow.


• Bug report issue template and pull request template.

Changed

• Public repository preparation: removed internal dev/PRD documents; aligned repo name with Moodle convention (moodle-local_chemillusion).

0.2.0 - 2026-06-23

Changed

• Renamed plugin display name from "ChemIllusion Study Cards" to ChemIllusion Study Tools throughout user-facing text and documentation.


• Aligned Moodle support documentation: range 4.3 through 5.0.x, automated CI on 4.3/4.5, local dev/testing on 5.0.8.

Fixed

• Privacy API now fully covers local_chemillusion_events (metadata, context discovery, user listing, export, deletion).


• Privacy API now declares pubchem_pug_rest as an external location.


• lookup_molecule AJAX endpoint: alt_types return schema corrected from scalar to array.


• All top-level page scripts now use plugin-relative require_once(__DIR__ . '/../../config.php') instead of fragile $_SERVER['DOCUMENT_ROOT'] bootstrap.


• Release packaging (scripts/package-plugin.sh) now fails hard when RDKit assets are missing; added --without-rdkit flag for local-only builds.


• RDKit.js pin updated to npm version 2024.3.5-1.0.0 (previous 2024.09.6 URL returned 404 on unpkg).

0.1.0 - 2026-06-13

Initial Phase 1A + Phase 1B scaffold.

Added

• Admin settings: operating mode, external-service toggles, ChemIllusion
  connection (base URL + signing secret), and privacy controls.


• PubChem PUG REST client with server-side cache and a cleanup scheduled task.


• Molecule lookup page with progressive-enhancement (works without JavaScript)
  and a live AJAX lookup web service (local_chemillusion_lookup_molecule).


• Study decks and cards: data model, repository, card generator, and a
  local_chemillusion_save_deck web service.


• Reagent (Organic 1/2) and functional-group dictionaries (with SMARTS).


• Account-link funnel: signed, time-limited launch state and minimal local
  mapping table; no grades or rosters are sent.


• Local-only usage counters and a teacher/admin dashboard.


• Privacy API provider covering links, decks, cards, and the external link.


• Phase 1B RDKit.js/WASM lazy loader, SVG renderer, SMILES validation,
  functional-group matcher, and static highlighting (binary fetched via
  scripts/update-rdkit-js.sh).


• Accessible, keyboard-operable flashcard player (no auto-flip).


• PHPUnit and Behat test scaffolding, Moodle Plugin CI, and packaging scripts.
