+
+All notable changes to enowX Coder are documented here.
+
+---
+
+## [0.2.5] — 2026-04-23
+
+### Excalidraw Canvas — Collaborative Whiteboard
+- **New feature**: Full Excalidraw whiteboard integrated as a Canvas tab — switch between Chat and Canvas via segmented control in header
+- Drawings persist per project in SQLite — auto-save every 1 second, auto-load on project switch
+- Dark/light theme syncs with app theme toggle
+- Full Excalidraw toolbar: shapes, arrows, text, freehand, colors, layers, export to disk
+
+### AI Canvas — Generate Diagrams with AI
+- **New feature**: AI prompt bar floating at bottom of canvas — describe what to draw, AI generates Excalidraw elements
+- AI generates native Excalidraw JSON (rectangles, ellipses, diamonds, text, arrows with bindings)
+- **Context-aware editing**: Existing canvas elements are sent to AI as context — ask "change color of 2021 to yellow" and AI modifies only that element while preserving everything else
+- Provider and model selector in canvas prompt bar (shared with chat)
+- Merge behavior: AI returns full element set for edits, appends for new drawings
+
+### Conversation Memory — Smart Context Management
+- **New feature**: AI now remembers previous messages in the same chat session
+- Loads user messages + agent outputs from DB, interleaved chronologically
+- **Sliding window**: Max 20 recent message pairs to prevent token overflow
+- **Strip html:preview blocks**: Widget HTML (5-10KB each) compressed to ~300-500 byte summaries preserving chart data, labels, colors, metrics
+- **Token budget**: History capped at ~32K chars (~8K tokens), prioritizing recent messages
+- **Smart truncation**: User messages max 500 chars, assistant max 1500 chars, cut at word boundary
+- `summarize_html_widget()` extracts Chart.js datasets, labels, colors, metric values from HTML for targeted edits
+
+### Provider System Overhaul
+- **Enable/disable toggle**: Per-provider on/off switch in Settings detail panel — disabled providers hidden from chat dropdown
+- **Add Provider flow**: "Custom" replaced with "+ Add Provider" button — create unlimited custom providers with name, base URL, API key, model
+- User-created providers appear in sidebar list with enable/disable dot indicator
+- Delete provider resets selection to enowX Labs
+- `is_enabled` column added to providers table (migration)
+- **Manual model add**: Input field in Available Models section — type model name, click Add, auto-enabled
+- Manual models persist in DB and appear in list even after Settings reopen (merged with API-fetched models)
+
+### Token Optimization
+- **MAX_REACT_ITERATIONS reduced**: 20 → 10 — prevents excessive API calls per request while still allowing complex tasks
+- **Auto-select provider + model on app start**: If only 1 provider enabled, auto-selected as default. First available model auto-selected. No manual selection needed.
+- Provider dropdown shows as label when only 1 provider (no unnecessary dropdown)
+
+### Dark Mode — Warm Claude Palette
+- Replaced cold pure black (#0a0a0a) with warm Claude-inspired tones
+- Background: #1a1816 (warm dark brown), Surface: #201e1b, Text: #e8e4de (warm off-white)
+- Accent color: #D4845A (terracotta/copper) matching light mode
+- Borders, links, focus rings all use warm tones
+- Danger colors updated to Claude red palette (#E24B4A)
+
+### Markdown Table Fix
+- `fixMarkdownTables()` rewritten — fixes malformed tables from streaming
+- Auto-corrects separator row column count to match header
+- Splits crammed rows (multiple rows on one line)
+- Injects missing separator rows without duplicating between data rows
+- Applied to both agent streaming output and final chat messages
+
+### Scroll Bounce Fix
+- Removed gradient overlay conditional mount/unmount (caused layout shift loop)
+- Added `isAutoScrolling` guard — scroll events from auto-scroll ignored
+- Throttled streaming scroll to 80ms intervals
+- `requestAnimationFrame` for scroll-to-bottom to avoid layout thrashing
+
+### UI Polish
+- Left sidebar font sizes increased: project names, session titles, labels from 12px to 13px
+- Model dropdown: `max-height: 360px` with scroll for long model lists
+- Footer bar removed for cleaner layout
+- Right sidebar toggle button in header (hidden when sidebar open)
+- enowX Flux tooltip on hover with description and token usage info
+
+---
+
+## [0.2.0] — 2026-04-22
+
+### enowX Flux — Generative UI System
+- **New feature**: enowX Flux — AI generates interactive charts, diagrams, SVG illustrations, dashboards, and widgets inline in chat
+- Integrated Claude.ai's reverse-engineered design system (CSS variables, SVG color ramps, pre-styled form elements, light/dark mode)
+- `html:preview` code blocks render as live interactive iframes with full JS/CSS support
+- Chart.js, D3, Canvas, and CDN libraries supported inside previews
+- Debounced iframe rendering during streaming (400ms) to prevent flicker
+- Auto-resize iframe to match content height via direct DOM measurement + ResizeObserver
+- Re-measure on window resize for responsive behavior
+- Expand preview to fullscreen modal with source code view and copy button
+- Toggle button in header to enable/disable Flux (saves ~3K tokens per request when off)
+- Custom tooltip on hover explaining what enowX Flux does
+- Enhanced `PREVIEW_GUIDE` with full Claude guidelines: diagram types, illustrative patterns, interactive examples, UI components, art/illustration
+
+### Welcome Screen
+- Welcome screen with greeting + quick action chips (Write, Learn, Code, Personal, Brainstorm)
+- Chips prefill prompt in input bar on click
+- Auto-create project + session when user sends first message (no need to open folder first)
+- Input bar always enabled — no more "Open a folder to start chatting"
+
+### Chat Improvements
+- **Streaming output**: Agent responses now stream token-by-token with blinking cursor, instead of appearing all at once
+- **Auto-rename chat**: After first AI response, LLM generates a short 2-5 word title (e.g. "Greeting", "React Auth Setup")
+- **Copy response**: Copy button below each AI response with model name and generation duration
+- **Agent info relocated**: Model name and duration moved to bottom of response, agent type stays at top
+- **Markdown table fix**: `fixMarkdownTables()` utility fixes malformed tables from streaming — auto-corrects separator column count, splits crammed rows, injects missing separators
+- **Scroll bounce fix**: Removed gradient overlay mount/unmount loop, added `isAutoScrolling` guard, throttled streaming scroll (80ms)
+
+### Sidebar
+- **Left sidebar toggle**: Click logo icon to collapse/expand with smooth CSS grid animation (0.25s cubic-bezier)
+- **Right sidebar toggle**: Toggle button inside sidebar header + in chat header when closed
+- **Sidebar font size**: Increased project names, session titles, and labels from 12px to 13px for readability
+- **Footer removed**: Cleaner layout, sidebar toggles moved to header
+
+### Settings & Providers
+- **Custom provider fix**: Added "Default Model" input field for Custom/Ollama providers — fixes silent save failure
+- **Error feedback**: Save errors now shown as red inline messages instead of silent `console.error`
+- **Base URL save**: Can now save base URL even when provider doesn't exist yet (auto-creates)
+- **Model dropdown scroll**: Fixed dropdown clipping — added `max-height: 360px` with scrollbar for long model lists
+
+### Header & Navigation
+- **Rename chat**: Click pencil icon → inline edit with Enter/Escape
+- **Three-dot menu**: New Chat + Delete Chat options
+- **Delete confirmation**: Custom dark-themed confirm dialog (replaced broken native `window.confirm`)
+- **Theme toggle**: Dark/light mode switch in header
+- **enowX Flux toggle**: ON/OFF pill button with status tooltip
+
+### Theme & Design
+- **Dark mode warm palette**: Replaced cold pure black (#0a0a0a) with warm Claude-inspired tones (#1a1816 bg, #e8e4de text, #D4845A accent)
+- **Light/dark preview sync**: iframe previews now use class-based theme switching (`.light`/`.dark`) instead of `prefers-color-scheme` media query — syncs with app toggle
+- **Tauri dialog permissions**: Upgraded from `dialog:allow-open` to `dialog:default` for full dialog support
+
+### Bug Fixes
+- **Agent request fix**: Fixed parameter mismatch — frontend now wraps `run_agent` params in `request` object matching Rust `RunAgentRequest` struct
+- **API key pre-flight**: Added validation check before API calls — clear error message instead of cryptic 401
+- **First message missing**: Fixed race condition where `setActiveSessionId` triggered DB reload that wiped optimistic user message
+- **Clippy warnings**: Fixed all Rust clippy warnings — dead code removal, parameter struct refactoring, simplified patterns
+
+### Infrastructure
+- **Tauri capabilities**: Added `dialog:default` permission for ask/confirm/message dialogs
+- **Generate title command**: New `generate_title` Tauri command — LLM generates chat title via non-streaming API call
