What's New in Wing Pro

Wing 12.1 introduces autonomous Python development. You write the specification, answer questions, and review results, while the new Tasks Manager and its worker agents write, test, debug, review, document, and commit the code. Wing keeps you in control of what you delegate, how you review the results, and when code ships.

Wing Pro 12.1 works with your choice of AI agent: Claude Code, Codex, Antigravity, Copilot, Cursor, goose, OpenCode, or any other agent that speaks the Agent Client Protocol (ACP).

These build on the AI agent integration introduced in Wing 12: an AI Agent tool, a Tasks tool for planning and reviewing agent work, and a set of MCP servers that give the agent access to Wing's source code analysis, unit testing, and debugging features. Use convenient FIX actions to ask the AI agent to fix bugs, failing tests, code warnings or write missing tests. See Autonomous Development with AI Agents for details.

Wing 12 also adds pseudo-terminal support for OS Commands and Debug I/O, tools in editor splits, a reorganized Tools menu, automatic test discovery, Preferences search, and more.

The release of Wing 12 comes with some changes to the product line: The Commercial vs. Non-Commercial use distinction has been replaced by two feature-based tiers -- Wing Pro (with AI agent tools) and Wing Classic (traditional IDE features only). Wing Personal has been discontinued. See Pricing and the Upgrading section below for details.

Previously, Wing 11 added support for Python 3.14, package management with uv, improved Python code analysis, updated the UI localizations, improved diff/merge, and added easier custom key binding assignment. Wing 10 added support for Python 3.13 and 3.12 (including faster debugging with the new PEP 669 low-impact monitoring API), support for running the IDE on arm64 Linux, Poetry for package management, and Ruff for code warnings and reformatting.

Autonomous Development with the Tasks Manager

Wing 12.1 adds the Tasks Manager, an agent that runs the Tasks tool's queues for you. You write tasks, mark the ones you want started as Ready, and review what comes back. The Manager decides task order, keeps apart work that edits the same files, and runs closely related tasks in a shared session. Tasks run autonomously: each works as far as it can and ends with a report of the judgement calls it made and any questions it has left. A new Questions tab collects everything waiting for you in one place for your review. Problems agents notice along the way are added to the Plan tab. Those closely related to ongoing work may be queued; others wait for your review. Wing keeps you in control: every decision and change the Manager makes is tracked and can be reverted or revisited. Commits remain manual unless you choose otherwise. Turn the Manager on with the Turn On button in the Manager area at the top of the Tasks tool's Execute tab.

Your Choice of AI Agent

Wing Pro 12.1 works with Claude Code, Codex, Antigravity, Copilot, Cursor, goose, and OpenCode, and any other agent that speaks the Agent Client Protocol (ACP). Agents with their own terminal interface run it inside Wing's AI Agent tool. Others may run through ACP in Wing's own AI agent conversation UI. Set Up for AI Agent in the Project menu configures your project for each AI agent you wish to use with it. Each queue in the Tasks tool can use a different type of agent. You bring your own subscription or API key for the agent you choose. A new Configure AI Agents window points Wing to your API keys and other credentials.

AI Agent Integration and MCP Servers

Wing 12 integrated AI agents directly with the IDE. Wing's MCP (Model Context Protocol) servers give the agent structured access to source code analysis, the debugger, unit tests, and code review -- so the agent finds definitions without grepping, runs only the tests affected by its changes, and uses real breakpoints instead of guessing. In our benchmarks with Claude Code this reduced token use and time for many common tasks. See Autonomous Development with AI Agents for details.

Tasks Tool

The Tasks tool lets you plan, queue up, execute, review, and audit the history of AI agent development tasks, making it easier to supervise the agent's work and inspect changes before committing them to revision control. Wing 12.1 lets you set goals aside for later, triage what agents found in a new Incoming view, and see what runs next in every queue with Up Next. Tasks that agents create are marked with their origin, and a Compact button fits more tasks on screen. Every task has a short label such as T12 that links to the task wherever it is cited, and every tab has mini-search.

FIX Actions and Write Tests

Wing 12 added AI agent driven FIX actions that hand off the current debugger bug, failing unit tests, or code warnings directly to your AI agent for resolution. Write Tests items in the Testing and editor context menus prompt the agent to write unit tests for selected code.

Pseudo-Terminal Support

The OS Commands and Debug I/O tools now default to using a pseudo-terminal that implements full ANSI terminal emulation, so you can run and debug programs that use color output, cursor positioning, or full-screen TUIs.

Tools in Editor Splits and Reorganized Tools Menu

Tools can now be added or dragged to editor splits, not just in the tool areas, allowing for much more flexible workspace layout. The Tools menu has also been reorganized into related groups, with an Other sub-menu for lesser-used or legacy tools, making the more commonly used tools easier to find.

Test Discovery and Preferences Search

Wing 12 adds an Auto-Discover Test Files option in the Testing tab of Project Properties, so you usually don't need to specify test file patterns or add test files individually to the Testing tool. Wing 12 also adds discovery of individual unit tests within files via Discover Tests in Project in the Testing menu. The Preferences dialog now supports text search and back/forward navigation, making it easier to find and change settings.

Python 3.11, 3.12, 3.13, 3.14, and 3.15

Wing 12 added support for Python 3.15. Wing 11 added support for Python 3.14. Wing 10 added support for Python 3.12 and 3.13, including (1) faster debugging with PEP 669 low impact monitoring API, (2) PEP 695 parameterized classes, functions and methods, (3) PEP 695 type statements, and (4) PEP 701 style f-strings.

Package Management with uv and Poetry

Wing 11 added support for package management with uv in the New Project dialog and in the Packages tool in the Tools menu. Wing 10 added support for package management with Poetry.

Ruff Code Warnings & Reformatting

Wing 10 added support for Ruff as an external code checker in the Code Warnings tool, accessed from the Tools menu. Ruff can also be used as a code reformatter in the Source > Reformatting menu group. Ruff is an incredibly fast Python code checker that can replace or supplement flake8, pylint, pep8, and mypy.

The change log on the downloads page contains a detailed list of all changes in each release.

Legacy AI Features

The single-query AI features originally introduced in Wing 11 (the AI Coder and AI Chat tools, used to set up and run individual queries against an LLM) are considered legacy in Wing 12 and hidden from the user interface by default. They remain available in projects that already use them, and can be re-enabled in the Project Properties > AI preferences area, for users that wish to continue using them. See Legacy AI Assisted Development for details.

Upgrading

If you are upgrading from an earlier major release of Wing, see Upgrading for details and Migrating from Older Versions for a list of compatibility notes.

Product line changes in Wing 12:

The old Commercial / Non-Commercial use distinction has been retired. Going forward, licenses are defined by features and price, not by who you are or what you do. Anyone can buy either tier for any purpose.

Wing Pro (the upper tier) is the full-featured Python IDE including AI agent development tools. Pricing is unchanged from prior versions,. Existing Commercial license holders automatically map to Wing Pro -- the upgrade path is unchanged.

Wing Classic (the base tier) is the complete traditional Python IDE for hands-on development, with no AI agent features. Existing Wing Pro Non-Commercial license holders automatically map to Wing Classic -- same license codes, same pricing, no use-case restriction.

Wing Personal is discontinued. It is no longer maintained as of Wing 12. Existing Wing Personal users have three options:

Stay on Wing Personal 11.x -- it continues to work indefinitely. No kill switch. Older versions remain available from the Wing Personal downloads page.

Switch to Wing 101 -- a free, simplified Python IDE for teaching and self-study. Available from the Wing 101 downloads page.

Purchase a Wing Classic license -- includes many features that were not available in Wing Personal including full debugger, code intelligence, project management with version control, refactoring, unit testing, framework support, etc. See Pricing.

Wing 101 is unchanged and continues as a separate, free download for teaching and self-study.
