SynaBun Changelog

Raw internal changelogs are archived in changelog/.

v.2026.03.31

Added — Message Queue System

• Queue messages while Claude is processing — Stack multiple messages in a FIFO queue that auto-advances between turns. Includes drag-to-reorder, inline editing, pause/resume, and a collapsible queue tray UI
• Keyboard behavior change — Enter while running now queues the message; Shift+Enter triggers the existing /btw interrupt. Send button icon updates dynamically based on state

Added — Notification Click-to-Navigate

• Clicking a notification focuses the exact source — Toast clicks route to the specific terminal session or Claude panel tab that triggered the notification. OS banner notifications use service worker postMessage relay for click-through routing
• All 10 notification call sites updated — 8 panel calls pass tab ID, 2 terminal calls pass session ID

Added — Hook-Side Auto-Recall

• Top 3 related memories injected into every prompt — The prompt-submit hook calls /api/hook-recall on every substantive user prompt, auto-detects project from cwd, and injects matching memories (score >= 0.4) directly into additionalContext with a 3-second timeout and silent fallback

Added — Browser Stream Toggle

• Disable screencast to save ~50% CPU — New toggle in Settings > Browser. When disabled, all CDP frame capture, encoding, and WebSocket broadcasting stops. All MCP browser tools continue working — only the Neural Interface preview stream is affected

Added — Edit Plan in Code Editor

• Open plan files directly in the Neural Interface editor — Clicking "Edit plan" on the post-plan action card opens the MD file in the code editor with a green accent banner. On save, the updated plan is auto-sent to Claude. Falls back gracefully for plans from prior sessions

Added — Recall Settings Redesign

• 4 recall profiles replace basic token budget — Quick (3 results, tight matching), Balanced (5 results), Deep (10 results, loose matching), Custom (opens all individual controls). Profile selection auto-configures all parameters
• Fine-tune controls — Results per recall, minimum importance, similarity threshold, content length, session context toggle, and recency boost
• Impact indicator — Shows estimated tokens per recall, reachable memories, and session context status

Added — Isolated Agent System

• Spawn Claude Code as independent child processes — Full session isolation with no hook interference, no MCP cross-talk, and cross-platform process management (no node-pty dependency). Each agent gets its own session ID, strict MCP config, and bypass permissions
• Agent cards in Automation Studio — Live-streaming output with tool call count, cost display, elapsed time, and stop/remove controls

Added — Image Gallery

• Floating draggable panel for browsing captured images — Search, type filters (Screenshots/Attachments/Whiteboard/Pastes), sort options, favorites toggle. Full lightbox with keyboard navigation (arrow keys, Escape) and action buttons (favorite, add to whiteboard, download, delete)

Added — Cron-Driven Schedule System

• Create recurring automations with cron expressions — Timezone support, day-of-week themes for content calendars, 18 cron presets across 3 groups (Frequency, Daily, Weekly). Full CRUD API with WebSocket events for live UI updates. Schedules tab in Automation Studio with status badges and test-fire button

Added — Multi-Browser Session Isolation

• Dedicated browser per automation — Each automation gets its own browser session with environment-based pinning via SYNABUN_BROWSER_SESSION. Concurrent automations no longer fight over the same browser. Browser cleanup on loop stop

Added — Multi-Tab Browser Architecture

• Tabs per browser session — Create, switch, and close tabs via REST and WebSocket. Each tab stores its own page, CDP session, URL, and title. Active tab aliases preserve backward compatibility with all existing MCP tools

Added — Notifications Settings Tab

• Dedicated notifications panel — Master toggle, system permission status with color-coded indicator, sound controls with volume slider and test button, OS banner toggle, action-only filter, and end-to-end test notification button

Added — Auto Backup System

• Scheduled ZIP backups to a user-chosen folder — Configurable frequency (30min to 24h), native OS folder picker, atomic write pattern, single-file replacement. Settings UI with last backup time, file size, and error status

Added — Whiteboard Enhancements

• Shape picker submenu — Rectangle, Circle, and Triangle presets with inline SVG icons
• Floating move handle — 4-directional arrow on selected text/list elements, mirroring the rotate handle
• Backdrop toggle button — Eye icon on all windows to show/hide the backdrop overlay
• Multi-select shortcut — M key toggles multi-select mode

Added — Automation Studio Icon Picker Expansion

• 13 new icons — Social media (X, Instagram, Facebook, LinkedIn, TikTok, YouTube, WhatsApp, Discord), AI platforms (Claude, OpenAI, Gemini), Leonardo, and pin

Added — Content Negotiation & Markdown Extraction

• Browser markdown extraction — Strips noise elements, prefers main/article content areas, converts via node-html-markdown. New format: "markdown" parameter on browser_content tool
• Lightweight HTTP fetch — Accept: text/markdown header negotiation with Cloudflare header detection and HTML fallback

Added — LinkedIn Jobs Browser Extractor

• Structured job listing extraction — Handles search results and homepage recommendations. Extracts 11 fields per job including salary parsing across multiple currencies. De-duplicates by job ID

Fixed — Permission Spam in Claude Code Sidepanel

• Events leaked through buffer gate — All message types now blocked during active permission prompts or ask questions (except control_request). Denying a permission now properly kills the running process. Queue and buffer cleared immediately on deny

Fixed — AskUserQuestion Card Duplication

• Buffer flush ordering — Reordered to flush while dedup flag is still active. Added DOM-level guard against rendering duplicate ask cards when an active card already exists

Fixed — Edit Plan Auto-Implementing

• Edited plans now show review card — After saving in the code editor, a PLAN UPDATED card renders with Implement/Compact/Edit buttons instead of auto-sending to Claude. Edited content is preserved and sent when implementing

Fixed — Neural Interface Memory Leaks (11GB+)

• DOM pruning — Messages capped at 600 nodes with batch removal of oldest 150. Message buffer capped at 500 during permission prompts. Event listener cleanup on Automation Studio panel close — previously leaked 6 document-level listeners per open/close cycle

Fixed — Context Gauge Showing Inflated Values

• Cumulative token counts replaced with per-turn values — Gauge now uses correct per-turn usage from assistant events instead of cumulative result event values that could reach multiples of the context window

Fixed — Plan System "PLAN COMPLETE" Card Not Rendering

• Detection moved to assistant events — In --print mode, built-in tool results aren't emitted. ExitPlanMode detection now fires from tool_use blocks in assistant events with flag-based handoff to the result/done handlers

Fixed — Plan Storage Cross-Session Leak

• Plans now matched by content instead of modification time — Four matching strategies (filename, exact content, substring, heading) replace the old blind "newest file wins" approach that grabbed wrong plans when multiple sessions were in plan mode

Fixed — Floating Browser Close Button After Reconnection

• ID-based lookup replaces object identity — Close and pin handlers now re-find the live session by ID instead of using stale closure-captured references that go invalid after session reconnection

Fixed — Loop Cross-Session Leaks

• Terminal session ownership tracking — Loop driver, hook pending claims, fallback scans, and session-start detection all now filter by terminalSessionId instead of blindly grabbing the first available loop

Fixed — Loop Time Cap Silently Clamped

• Raised from 60 to 480 minutes — The terminal loop endpoint had a stale Math.min(..., 60) cap that silently truncated all values. Iteration cap raised from 50 to 200. UI sliders updated to match

Fixed — Browser Screencast Freezing

• Backpressure-aware frame renderer — Replaced unbounded Image() creation with a latest-frame-wins pattern. Only one decode runs at a time; stale frames are dropped. Applied to all three rendering surfaces (terminal, floating, panel)

Fixed — White Dropdown Backgrounds on Windows

• color-scheme: dark declaration — Added to :root so native form controls render in dark mode on Windows Chrome/Edge

Fixed — Session Isolation Leak Across Tabs

• Project/model/effort are now per-tab state — Previously stored in shared global storage, causing one tab's project selection to leak into another. Standalone chat page also fixed with sessionStorage-based tab isolation

Fixed — Image Pipeline

• File attachments now reach Claude — Fixed 5 separate issues: disabled send button ignoring files, early return blocking file-only sends, path chips persisting after send, no framing text for attached files, BTW interrupt discarding files
• Pasted/dropped images — Saved as temp files with Read tool instruction instead of multimodal (unsupported in --print mode)
• Clipboard operations — Fallback for non-HTTPS contexts when accessing Neural Interface over LAN

Fixed — Agent Launch Dialog

• DOM values read before dialog destruction — All input reads moved before closeLaunchDialog() which calls .remove(). Previously all 5 reads returned null, making agents launch with empty MCP config and no browser session

Fixed — Cost Tracking

• Navbar label stuck at $0.00 — Event payload now includes session cost field. Widget no longer overwrites navbar with monthly total. Docked widget fetches data on init

Fixed — Pencil Tool Screenshot Rendering

• Smooth bezier curves replace polygonal line segments — Screenshot capture now uses pre-computed SVG path data instead of straight lineTo() segments. Increased smoothing passes and reduced jitter threshold

Fixed — Window Controls Overlay on macOS

• CSS specificity fix — WCO padding no longer silently overwritten by base styles. Theme color matched to navbar composited appearance. Vertical alignment matched to traffic light midpoint

Fixed — Notifications in Safari PWA

• Service worker routing — Replaced direct Notification constructor with serviceWorker.postMessage() → registration.showNotification() flow

Fixed — Whiteboard List Items Lost on Reload

• Content synced before persisting — List contenteditable DOM content now flushed to the model array before serialization. Added flush calls to all exit paths

Changed — Toolbar Modernization

• Apple-style unified frosted glass pills — Top-right navbar and bottom-right workspace toolbar converted from separate button groups to continuous pill bars with shared backdrop blur. Refined hover effects with spring animations, unified active state dots, and cleaner SVG icons

Changed — Window Header Modernization

• Unified design language across 13+ window types — Gradient backgrounds, softer borders, lighter title weight, ghost-style action buttons, and red-tint close hover

Changed — Batched AskUserQuestion Submission

• Options toggle freely until submitted — Submit button with progress counter (Submit 2/3) enables when all questions answered. Free-text questions render inline input instead of using the main chat box

Changed — Leonardo.ai Converted to 100% Browser-Based

• Removed all API tools — 4 browser tools replace 14 API tools. No API key required. Comprehensive UI map with 18 image models, 23 video models, 39 motion controls, and 3-layer style stacking. Skill modules expanded with full questionnaire flows

Changed — Automation Studio Launch Flow

• Inline panel replaces overlay modal — Launch configuration renders directly inside the detail view. New "Run in" destination toggle for Floating vs Side Panel

Changed — Focus Mode Zero-Resource Consumption

• All event handlers paused in 3D and 2D views — Pointer, keyboard, wheel, and camera input fully disabled during focus mode. Resize handlers intentionally left active

Changed — Session Monitor Rewritten

• Proper draggable/resizable window — Replaces narrow fixed panel. Three tabs: Sessions (cards with uptime/PID), Agents (status badges/cost), Health (leak severity grouping with cleanup actions)

Changed — Browser Screencast Optimizations

• 30fps frame cap — Frames arriving faster than 33ms are dropped before decoding
• Pause on minimize — Minimized browser pills stop CDP screencast entirely
• Focus-based throttling — Non-focused browser windows throttle to ~2fps
• 5-minute idle timeout — Auto-pause after inactivity; canvas interaction resumes
• Server-side backpressure — Clients with congested WebSocket buffers are skipped

Changed — Window Close Behavior

• Outside-click closing disabled — All windows now close exclusively via ESC or close button. ESC key handlers added to Settings, Sessions, Help, Image Gallery, and Terminal dir picker

Changed — Custom Dropdowns for Settings

• Native <select> elements replaced — All 4 Settings dropdowns converted to themed custom dropdown components for consistent cross-platform appearance

Changed — Settings Add Project

• Native OS folder picker — Replaces custom inline folder browser that had no drive/volume switching on Windows
