Changelog

Every release, every feature. From day one to now.

October 2026

v3.6.2

Design Systems — Every Detail, in Both Directions

  • New: Design Systems — 34 ready design languages, from editorial and bento to glassmorphism, mission-control and trading-terminal, each with its own written spec and token contract.
  • Not a mood board — a contract. Attach a system and every artifact must paste its `:root` block and reference everything through `var(--name)`: no invented tokens, no stray hex. See it rendered as a live specimen (type scale, palette, buttons, surfaces, spacing) before you commit to it.
  • Make it yours — ask an agent to create, refine or retire a design system and it lands in `.codey/design-systems/`, editable and portable, and packages copied from OpenDesign drop in without conversion.
  • Browser, rebuilt for smoothness — the frame stream now trades JPEG quality before it ever touches resolution, decodes off the main thread in a worker pool, and drops superseded frames before painting, so Retina panels stay sharp on calm pages and heavy animations stop janking.
  • Preview what you build, right where you built it — the browser opens your project's own HTML and SVG from disk with fit-to-panel, zoom and inspect intact, confined to your workspace and never reachable from the AI tool or the web app.
  • Every Codey tool, inside your CLI agent — Claude Code, Codex and the rest now call browser, blueprint, design systems, web search, skills and your MCP servers through one turn-scoped bridge, running Codey's real permission pipeline on every call.
  • Arabic, completely — Codey now mirrors properly end to end: titlebar, side panel, tab strip, settings, sliders, segmented toggles and menus all follow right-to-left, with directional icons, mirrored glyphs and every string translated across all 15 languages.
  • Colors that stay put — a versioned theme engine clears out stale cached palettes on boot, the native window background now matches the app so no dark edge flashes on resize, and custom themes survive in the packaged app.
  • Faster where it counted — long sessions render lighter: collapsed steps release their memory, scroll tracking stops forcing layout, hidden terminal output queues, and only visible file tabs are polled.
  • A calmer prompt dock — context usage is now a quiet gauge instead of a button, and the thinking-effort slider and Act/Plan toggle finally behave at every width and in both directions.
  • New app icons — one layered source now drives macOS appearance, so the Dock icon follows your system's Default, Dark, Tinted and Clear styles instead of shipping a separate dark copy.
  • And a long list of fixes — prompt improvement no longer returns reasoning tags or broken mentions, free-tier models are grouped correctly across Desktop and TUI, transient capacity errors retry instead of failing the turn, and browser startup is bounded with real progress instead of a silent wait.
September 2026

v3.6.1

Blueprint — Every Plan, Perfectly in Order

  • Meet Blueprint — the next evolution of Plan & Tasks. Ideas become a living board: a plan header, and tasks you can shape, refine, and keep.
  • Every task is self-contained — a full prompt with its own goal, files, and definition of done. Run it as its own session, prompt already loaded.
  • Saved and ordered better — the board persists per project, survives restarts, and rearranges with a simple drag.
  • Live progress, at a glance — tasks move to In Progress, Blocked, Done, or Failed on their own as their sessions work.
  • Edit anytime, everything follows — rename or refine a task and its session keeps up: new name, new prompt on next open.
  • Ask, and it's recorded — agents save a discussed plan to the board on request, only after you approve the split.
  • A calmer Codey — fixed the flicker and full-app refresh when the side panel opened, tabs changed, or the model list scrolled.
  • Fixed prompt hand-off — running a task always opens its session with the exact, latest prompt.

v3.6.0

Reimagined — Simpler, Faster, Smarter

  • Simpler by design — we threw away the template and redrew every page around one question: why is this here? The result is quieter, calmer, and radically clearer.
  • Dramatically faster — we rebuilt the engine underneath. Responses, session loads, and file operations now feel instant. No jank, no waiting.
  • Smarter agents, smarter workflow — Prometheus, Athena, Matis and Hermes now think deeper before they act, plan better, and delegate without losing context.
  • Local CLI, for the first time — run Claude Code, Codex and any agentic CLI directly inside Codey. Auto-detected, authenticated, and streamed live in one workspace.
  • Providers, finally fixed — add any custom provider in one click, discover models instantly, and see exactly what each model costs and can do.
  • Everything opens inside Codey — Word, Excel, PowerPoint, PDFs, images, audio and video, natively. No external apps, no broken previews.
  • Hardened everywhere — VCS diffs, binary files, RTL, scroll, permissions and subscriptions. Hundreds of small frustrations are just gone.
  • New Agent & Skill Studios — visually inspect, scope, and control every agent and skill. What was hidden is now clear.
  • Seamless updates — new upgrade experience with TUI dialogs, Homebrew support, and one-click rollback when you need it.
  • Refined sessions — safer deletion, cleaner sync across devices, and unified tabs for files, review and terminal. Your history stays clean.
  • Safer edits — new apply_patch engine makes every file change more accurate and more predictable.
  • Every pixel reconsidered — fresh icons, refined animations, and polished micro-interactions. Codey just feels right.
