oSlide2 v0.2.1 — Release Notes

Toast Notification System

js/components/toast.js — 5 notification types: SUCCESS (green), ERROR (red), WARNING (yellow), INFO (blue), LOADING (blue + spin animation)
Auto-dismiss (3s) or persistent (LOADING)
Returns .dismiss() for manual control
Integrated into AI chat errors, file save success/errors, export operations
main.js IPC handlers wrapped with try/catch; error/success events sent to renderer
preload.js exposes onFileSaved / onFileError listeners
css/toast.css — slide-in-right animation, color-coded backgrounds

Diff-based thumbnail rendering (renderThumbs) — DOM operations only for added/removed slides; existing nodes reused. dataset.bg and dataset.thumb skip innerHTML updates when unchanged
CSS caching (renderSlide) — dataset.css skips style.cssText writes when unchanged
Content caching (renderSlide) — dataset.ck skips element re-render when content unchanged
Batch updates (canvas.js onUp) — multi-select drag calls single renderSlide() + renderThumbs() instead of per-element updEl() (N renders → 1 render)
Element handles — only added to newly created elements, skipped on updates

docs/ARCHITECTURE.md — state flow diagram, module dependency graphs, undo/redo flow, canvas coordinate system
docs/API.md — full IPC handler reference (with param/return types), config schema, .slidelab format, Element Schema and Type Definitions sections
docs/CONTRIBUTING.md — code style rules (no semicolons, JSDoc required), load order, security rules, PR process
docs/JSDoc-STYLE.md — JSDoc3 format templates, single-line/multi-line rules, typedef examples
docs/DEVELOPMENT.md — setup, project structure, build commands, known issues, debugging
JSDoc comments added to all 10 JS modules (state.js, actions.js, renderer.js, canvas.js, panels.js, ai.js, ai-ui.js, fileManager.js, export.js, main.js): @param, @returns, @throws, @async, @typedef CoreState

main.js — validateConfig(): type/range checks for config values, catches corrupt configs
main.js — validateThemeColor(): enforces #RRGGBB format, rejects invalid colors, defaults to #ffffff
main.js — save-project-themes IPC handler validates colors before saving
homeTheme.js — _sanitizeColor() added, XSS prevention in renderThemes() innerHTML
renderMD() — href protocol whitelist only allows http:// and https://
Missing read-image IPC handler added to main.js (was defined in preload but handler was missing)

open-file-dialog IPC handler now returns { data, filePath, fileName } (structured object instead of raw JSON)
homeProject.js openFileDialog — _projectName and _projectPath passed to editor
editor.js loadData — defensive theme object handling (defaults to 'default' if .name missing)
.slidelab rect elements corrected: fill (background), borderColor, borderWidth, borderRadius — old bg/color fields removed
.slidelab files added to .gitignore, removed from version control (git rm --cached)

home.js split into homeTheme.js, homeSettings.js, homeProject.js; home.js reduced to 4-line orchestrator
All hardcoded hex colors migrated to CSS variables (19 variables in :root, managed via _setCSS())
theme.js — _setCSS() sets both light and dark mode CSS variables
ai.js — 4 separate system prompts consolidated into single SYSTEM_PROMPT constant
cloneObj() replaced with structuredClone()
editor.js split into ai-ui.js + export.js
AGENTS.md preserved, new docs/ folder created
Old LICENSE links removed from README
Version bumped 0.2.0 → 0.2.1
