[1.9.0] - 2026-10-22

Latest stable

Highlights

A code editor that knows your code: hover cards with types and docs, go to definition, find references, rename across the project, quick fixes (ruff, ty, auto-imports, uv add) and sticky scroll.
A Figma-style Properties panel: numbers you drag, position and size first, auto layout for flex and grid containers, a margin/padding box model, file and folder pickers and animations on events.
Dates, files and the system: date, range and time pickers, a calendar, a file picker, a drop zone, popups and pyzed.system (system info, launcher, network and power monitors).
Settings that follow you: one Settings dialog with search, user profiles, per-project settings, Reset to default and the project’s renderer (GPU or CPU) in pyproject.toml.

Features

✨ IDE features in the code editor: hover, go to definition (F12, Ctrl+click), type definition, back/forward, find references, rename symbol (F2), quick fixes (Ctrl+.) and sticky scroll; the language servers fall back to the designer’s Python when the project has no .venv. PR #183 by @albakore.
✨ Component icons take the color of their role (layout, input, action, navigation, display, media, system, custom) in the toolbox, the outline, the tray and the Properties/Events headers, and the Design tab is now called Toolbox. PR #184 by @albakore.
✨ One Settings dialog with search, user profiles, per-project settings and Reset to default; a project picks its renderer (GPU or CPU, graphics API, GPU and vsync) in pyproject.toml, and the MCP server reads and changes it. PR #185 by @albakore.
✨ Keyboard focus for selects, switches, check boxes, sliders, segmented controls and radio groups, pz.focusable for any control, and tooltip shortcuts shown as key caps from the keymap. PR #186 by @albakore.
✨ A Figma-style Properties panel: draggable numbers, Position first with align buttons, Text/Fill/Border/Spacing sections, auto layout, group and ungroup (Ctrl+G, Ctrl+Shift+G), path pickers for every file or folder property and animations on events. PR #188 by @albakore.
✨ ui.Calendar, ui.DatePicker, ui.DateRangePicker, ui.TimePicker, ui.file_input, ui.DropZone, pz.popup and pyzed.system (SystemInfo, Launcher, NetworkMonitor, PowerMonitor), with the toolbox split into Forms, Date & time and System. PR #189 by @albakore.

Fixes

🐛 A WSL project opened from Windows still lists its tools when Windows can’t reach the distro. PR #180 by @albakore.
🐛 A project’s components load whenever it opens, and a missing one is drawn as a warning instead of breaking the form. PR #182 by @albakore.
🐛 Windows updates no longer keep the old version: the installer clears the old files before copying, and Restart to update stops child processes, retries the folder swap and says so if it fails. PR #192 by @albakore.
🐛 Component descriptions show without raw reST marks: inline code in the Properties header and clean tooltips. PR #187 by @albakore.

Refactors

♻️ Custom events have their own place in the Events tab, apart from the built-in ones. PR #181 by @albakore.

[1.8.1] - 2026-10-22

Highlights

Updates that get out of the way: the update button moves to the top right of the title bar with a subtle blink, new versions download in the background, and Pyzed Design restarts cleanly on Windows after updating.

Features

✨ The update button sits in the title bar next to View, Help and Settings and blinks softly while it waits; the version found by the automatic check downloads in the background, the check runs again every 4 hours while the designer is open, a finished download is reused and old downloads are cleaned up. PR #178 by @albakore.

Fixes

🐛 Restarting after an update on Windows no longer fails with 'NoneType' object has no attribute 'flush' or opens several console windows. PR #178 by @albakore.

Docs

📝 The README is in English (Spanish in README.es.md), the repository has a CITATION.cff, and the docs sitemap carries real dates, unique titles and image descriptions. PR #177 by @albakore.

[1.8.0] - 2026-10-22

Highlights

A faster designer: Pyzed draws only what changed (cached components, form controls and panels), skips rebuilds for pointer moves that change nothing and redraws big forms for less.
Projects that stay in sync: Pyzed Design warns when a project needs a newer pyzed-ui or a sync, and the Dependencies tab keeps itself up to date.

Features

✨ Pyzed Design warns when a project needs a newer pyzed-ui or a sync, and keeps the Dependencies tab up to date. PR #172 by @albakore.
✨ Hidden dialogs and drawers stay off the designer canvas until one is selected. PR #171 by @albakore.
✨ Select and copy text in the Agent, Logs and Console panels, and close any tab. PR #173 by @albakore.
⚡️ Pointer moves that change nothing no longer rebuild the view, and big forms are cheaper to redraw. PR #174 by @albakore.
⚡️ Only what changed is drawn again: cached components, form controls and designer panels. PR #175 by @albakore.

Fixes

🐛 New projects are no longer created in the installed app’s folder (where they failed, or were deleted by the next update): Pyzed Design offers the last project’s folder or ~/Pyzed Projects, and refuses folders it cannot write to with a clear message. PR #170 by @albakore.

Docs

📝 The docs reach search engines and AI answer engines sooner: new and changed pages are sent to IndexNow on every deploy, Google, Bing and Yandex ownership checks come from repository variables, the PyPI page links the docs, and the FAQ tells Pyzed apart from the ZED camera SDK’s pyzed module. PR #176 by @albakore.

[1.7.0] - 2026-10-22

1.6.0 was tagged but never published (its wheels failed to build), so this release carries all of it.

Highlights

Sound in your apps: pyzed.audio, an audio engine in Rust with 23 modules joined by cables (oscillators, filters, effects, sampler, drums, sequencer, MIDI) and low-latency output on every system, plus waveform, spectrum, knobs, faders, a webcam view and a VCV-style rack with animated cables.
Export your app: Pyzed Design builds apps for Windows, macOS and Linux on x64 and ARM with PyInstaller or Nuitka, with an icon and a splash screen. An Android prototype builds APKs too.
Components that do work: timers, shortcuts, file watchers, processes, workers and web requests as non-visual components in Pyzed Design, and pyzed.services in code.
Hot reload that keeps your app running: the state stays and new attributes, initial values and methods are picked up without restarting.
A fuller designer: every library component in the toolbox (Dock included) with its properties and events, the startup form, any Pyzed file open in the editor, and animations you start from code with an easier timeline.
Tabs anywhere and WSL as Windows: any tab goes to any dock or window of its own, and under WSL Pyzed opens its windows as native Windows programs.

Features

✨ Put any tab anywhere: panels next to the forms, forms in docks, and a clearer tab drag. PR #136 by @albakore.
✨ Interface and code fonts and sizes in the editor settings, and duplicating lines on every cursor. PR #135 by @albakore.
✨ Non-visual components in Pyzed Design and pyzed.services: timers, shortcuts, file watchers, processes, workers, web requests and more. PR #138 by @albakore.
✨ An audio engine, pyzed.audio: modules joined by cables, low-latency devices (WASAPI, CoreAudio, PulseAudio/PipeWire, ALSA), MIDI, offline rendering to WAV and analysis for visualizers. PR #139 by @albakore.
✨ Audio UI components, a webcam view, a VCV-style rack with animated cables, audio demos and the Audio docs section. PR #142 by @albakore.
✨ Windows open as native Windows windows when Pyzed runs in WSL (pyzed windows setup, PYZED_WINDOWS=0 for WSLg). PR #150 by @albakore.
✨ Every demo in the welcome gallery of Pyzed Design: audio, games, animation, styling, shaders, AI and more. PR #153 by @albakore.
⚡️ Faster views with shared button parts, and the CPU renderer when the GPU is emulated. PR #157 by @albakore.
✨ Export apps from Pyzed Design for Windows, macOS and Linux on x64 and ARM, with PyInstaller or Nuitka, icons and a splash screen. PR #158 by @albakore.
✨ Android prototype: build APKs of Pyzed apps. PR #159 by @albakore.
✨ Hot reload keeps the state and picks up new attributes, initial values and methods without restarting. PR #164 by @albakore.
✨ Editor: choose the startup form, open every Pyzed file, indent with tabs and pace a held Backspace. PR #166 by @albakore.
✨ The library’s missing components in the designer’s toolbox (Dock included), with their properties and events. PR #165 by @albakore.
✨ Clearer animations: start them from code, an easier timeline and a “Start here” guide. PR #167 by @albakore.

Fixes

🐛 Claude Code, Codex and other agents start when Pyzed Design is opened from the desktop’s menu (Node.js found where nvm, volta and fnm put it), Retry no longer repeats the message, and Pyzed’s MCP server is added to Zed’s settings even when they have comments. PR #137 by @albakore.
🐛 The silent audio clock keeps real time when the system timer wakes late. PR #144 by @albakore.
🐛 Pyzed builds from source on Linux without ALSA’s headers: audio devices and MIDI come with the alsa feature, which the released wheels turn on. PR #149 by @albakore.
🐛 Claude Code and Codex run their current ACP adapters, so the new models and effort levels show. PR #151 by @albakore.
🐛 Your checkout and everything Pyzed Design starts run on Windows when they come from WSL. PR #152 by @albakore.
🐛 The Windows core builds without Windows’ folders on PATH, so maturin does not pick the Microsoft Store’s python.exe. PR #154 by @albakore.
🐛 Pyzed Design on Windows no longer freezes when it opens or creates a WSL project. PR #155 by @albakore.
🐛 The agents’ local servers no longer print dropped connections (WinError 10054) on Windows. PR #156 by @albakore.
🐛 A release stays a draft until its files are attached, and the download page links only files that exist. PR #163 by @albakore.

Refactors

♻ The new app template is centered with a flex box now that pz.box centers on the cross axis. PR #132 by @albakore.
♻ The agent settings show the everyday ones first and fold the rest under Advanced. PR #137 by @albakore.

Docs

📝 Game tutorials and the Animation docs section. PR #146 by @albakore.
🍱 Pyzed Design captures retaken with the event tray. PR #148 by @albakore.
📝 The events of every component, with imperative, declarative and functional examples. PR #168 by @albakore.

Internal

📦 pyzed-ui installs only from the prebuilt wheels, never compiling the Rust core. PR #140 by @albakore.
✅ The real-time audio test waits for the audio clock instead of a fixed sleep. PR #141 by @albakore.
👷 CI decides which jobs run from git diff, so pull requests with over 300 files still run their tests. PR #147 by @albakore.
💚 The release wheels build and test again: tests no longer share styles or need maturin, and the musllinux wheels build without ALSA. PRs #162 and #163 by @albakore.

[1.5.0] - 2026-10-20

Highlights

Program apps like the web: hover, pressed and focus styles with transitions, CSS-like stylesheets, pz.box (block, flex, grid and stack layouts), media queries with pz.viewport(), and components with children and context.
Errors never take the editor down: a Logs panel, error boundaries, an error dialog and a selectable console.
Agents you can follow: every agent step shows live, each agent’s modes and models in the composer, and Pyzed’s MCP server is added to the coding agents and editors on this computer.

Features

✨ Every agent step shows live, each agent’s modes, models and options in the composer, a Thinking toggle, remembered Always allow permissions, and Pyzed’s MCP server added to the AI agents and editors of this computer (Claude Desktop, Cursor, Windsurf, Gemini CLI, Codex, VS Code, Zed and more).

✨ State styles and transitions, CSS-like stylesheets, pz.box, media queries and breakpoints with pz.viewport(), children, context and animate= for components. PR #125 by @albakore.
⚡ Pyzed Agent designs faster: it starts out knowing the toolbox, themes, pz.ui components and best practices, gets the open document with each message and lays out a whole form with one add_controls call. PR #123 by @albakore.
✨ The agent’s steps go to the Logs panel: each message, tool call and result, files, permissions and errors. PR #126 by @albakore.
✨ MCP tools for timeline animations (.pzanim) and component states. PR #127 by @albakore.
✨ The MCP writes apps like a web page: boxes, stylesheets, media queries and nesting components. PR #128 by @albakore.

Fixes

🐛 Recent projects stay in PYZED_CONFIG_DIR when it is set. PR #125 by @albakore.

Docs

📝 The error and AI agent components in the component library. PR #130 by @albakore.

[1.4.0] - 2026-10-20

1.3.0 was tagged but never published: its Windows wheel build failed a test that is fixed in this version. Everything listed under 1.3.0 ships for the first time in 1.4.0.

Highlights

Detachable panels and work layouts: drag any panel out of Pyzed Design, stack panels together and save layouts for each kind of work.
A Zed-like Agent panel: new-thread menu, thread history, settings inside the panel, the ACP agent registry, skills, keep or reject each edit, external agent sign-in, follow-agent, a context meter, notifications, and threads and rules per project.

[1.3.0] - 2026-10-20

Highlights

Shader graphs: build shaders from nodes in the new Shader view of Pyzed Design, like Godot’s visual shaders, saved as .pzshad and compiled to WGSL (pyzed.shading).
Pyzed Design as an app: native installers for Windows (per user, no admin), macOS (.dmg) and Linux (install.sh), a preview update channel and a welcome window with 24 example projects.
Agents that build whole apps: sign in to Claude in the browser or with a Claude subscription, run_app and a plan checklist in the Agent panel, and MCP tools that plan an app (plan_app), show it live while it is built and work in the project’s environment (.venv, WSL).
Projects in the title bar: the project, branch and environment, with a project picker for open and recent projects.
New docs site: sections with a header navbar, every Designer view documented, a shader node catalog, basic, intermediate and advanced tutorials, every variant of each component and retaken screenshots and clips.

Features

Internal

👷 Speed up CI: cache the docs images, run jobs only for the files they check, a smaller PR matrix and parallel tests. PR #104 by @albakore.

[1.2.0] - 2026-10-20

Highlights

Games: a game loop (pz.frames), held keys (pz.pressed), on_key_up, sprites and pyzed.game, with Snake, Breakout and Neon Invaders demos and tutorials.
Shaders: pz.shader paints a widget with a WGSL function on the GPU, with showcase demos (game HUD, main menu, inventory, glass dashboard).
Integrations: tutorials and runnable demos for FastAPI, SQLAlchemy, SQLModel, Django, httpx and Pydantic, with pz.validation_errors and ui.field(error=).
A stronger AI agent: images, external MCP servers, external agents through ACP (Gemini CLI, Codex…), GitHub Copilot, Google Vertex AI, Claude through identity federation, sign-in from Pyzed Design and a Zed-like composer.
Pyzed Design feels like Zed: the project’s files with Zed’s right-click menu, any text file in the code editor, tabs you drag out into their own windows, a custom window frame, anchors that follow while you design, a compact details panel for properties and an icon picker.
Faster by default: import pyzed takes 78 ms instead of 178 ms, lighter view rebuilds and mimalloc in the native core.
Why Pyzed: a new docs section comparing Pyzed with tkinter, Qt, Kivy, Flet and others, with measured benchmarks.

Features

Internal

👷 Bundle the Agent panel’s GitHub and Google sign-in apps into the release builds from Actions secrets. PR #72 by @albakore.

[1.1.0] - 2026-10-19

Highlights

Large data: virtual lists and tables that only build the rows in view (200 000 rows in 0.2 ms per view) and @pz.memo to reuse view subtrees.
Real effects: animate rotation, size, padding and font size, with real blur, backdrop blur and bloom on the GPU and in software.
A better Pyzed Design: copy and paste between forms, data binding and validation, and a theme and language preview.
Accessibility: Tab focus between fields, the system’s reduce motion setting and a screen reader guide.
Input methods: Chinese, Japanese and Korean input in the code editor.
Safer by default: private agent threads, hidden secret files, a hardened sign-in and checked updates.
More platforms: wheels for musllinux, tested on Python 3.10 to 3.14 and on ARM Linux, Pyzed Design builds for Linux ARM and Intel Macs, and build attestations.

Breaking Changes

⬆️ Pyzed now requires Python 3.10 or newer. PR #52 by @albakore.

Features

✨ Add virtual lists and tables and memoized view subtrees for large data. PR #55 by @albakore.
✨ Add copy and paste between forms, data binding and validation, and theme/language preview to Pyzed Design. PR #56 by @albakore.
✨ Support input methods (IME) for Chinese, Japanese and Korean in the code editor. PR #57 by @albakore.
✨ Animate rotation, size, padding and font size, with real blur, backdrop blur and bloom. PR #58 by @albakore.
♿ Add Tab focus between fields, follow the system’s reduce motion setting and document screen reader support. PR #54 by @albakore.

Fixes

🔒️ Keep agent threads private (0600, with a Keep conversations switch), hide secret files such as .env and keys from agents, ignore forged sign-in callbacks and refuse updates without a checksum. PR #52 by @albakore.
🐛 Read component props on Python 3.14, where annotations are lazy. PR #52 by @albakore.

Internal

👷 Test on Python 3.10, 3.12 and 3.14 and on ARM Linux; build musllinux wheels, Pyzed Design for Linux ARM and Intel Macs, optional signing and notarization, and build provenance attestations. PR #52 by @albakore.
✅ Add visual regression tests and tests for workspace, navigation, overlays and agent threads. PR #53 by @albakore.

[1.0.1] - 2026-10-19

Fixes

🔒️ AI agents refuse tools marked writes=True when confirm_writes is on (the default) and no confirm callback was given, instead of running them without asking. Pass confirm= or set confirm_writes=False to keep the old behavior.
🔒️ pyzed mcp --transport streamable-http no longer offers the screenshot tool, which runs the code it receives, unless you add --allow-code. Over stdio nothing changes.
🐛 Pyzed Design refuses a .pzform or component saved by a newer Pyzed instead of opening it and losing what it does not know.
🏷️ Type stubs for the Rust core (_core.pyi) and py.typed, so editors and type checkers see every widget and command.

Docs

📝 Add the Stability and known limitations guide: the versioning and deprecation policy and what Pyzed does not do yet.

[1.0.0] - 2026-10-19

First stable version. From 1.0.0 on, the public API follows semantic versioning: breaking changes only land in a new major version.

Highlights

Animations and effects: animate any widget property, with ready-made animations, transitions between windows and visual effects such as glow, bloom, glass and transparency, in the library and in Pyzed Design.
AI agents: an Agent panel in Pyzed Design and pyzed.agents in the library, to write code and generate components and forms, with browser login or personal tokens kept in the system keychain. pyzed mcp also exposes Pyzed to external agents.
Built-in reference: a searchable, Godot-style reference of every component and function, inside Pyzed Design and from the library.
A Zed-grade code editor: Zed’s actions and keys, multiple cursors, find and replace.
Updates: Pyzed Design updates itself like Zed, with a What’s new tab.
New docs site: a component library, the Pyzed Design manual and a download page.

Features

✨ Add Zed-style updates to Pyzed Design with a What’s new tab. PR #40 by @albakore.

[0.4.0] - 2026-10-19

Highlights

Component Designer: draw reusable components with typed properties, state, methods and events, inherit from them and use them like any widget, with a Component view, tabs and a New component button.
A much richer designer: containers, dockable panels, menus, templates, a debug console, a Style section with a floating color picker, list and table editors, drag and drop from the outline, and a code editor with completion, diagnostics, folding and a minimap.
Styles and layout: CSS-like styles for every widget with global styles, gradients and masks, plus track grids, flex, resizable panels and a Zed-style dock.
Apps and projects: common events for every widget, translations, ready-made dialogs, uv projects and pyzed build to package an app.
Full API docs: every function, method, class and component is documented.
