What’s New in PyCharm 2026.2.1

This PyCharm release is a big one for anyone building with AI. Your agents can now roll up their sleeves inside your Jupyter notebooks – working against a live kernel instead of firing off disconnected scripts. And they finally know which Python to use, so packages land in the right environment every time.

We’re also welcoming marimo notebooks into the IDE and introducing changes to bundled plugins to keep PyCharm fast and focused.

Release highlights

Jupyter notebook skill for AI agents

Let AI agents such as Claude Code and Codex create, edit, and run .ipynb notebooks via PyCharm’s notebook model and a live kernel, so variables, models, and data persist across cells instead of disappearing when the agent shells out. For you, this means more reliable notebook and ML work – with fewer tokens used. To start, just open the AI chat and ask the agent to work in your notebook.

This functionality is available with a JetBrains AI subscription.

Agent environment coordinator

Tired of AI agents installing packages into the wrong Python environment? This new skill gives the agent your project’s configured interpreter and tool – uv, Poetry, pip in a venv, or conda – so commands target the right environment, not a system one. If none exists, it can set one up via PyCharm, and the agent decides how to use the information. To start, ask the agent to run or install something in your project.

This functionality is available with a JetBrains AI subscription.

marimo notebooks in PyCharm [third-party plugin]

You can now open, edit, and run marimo notebooks directly in PyCharm with the new plugin developed by the marimo team. 

Work with reactive cells and interactive UI elements in a dedicated notebook without leaving your IDE. Because marimo notebooks are stored as Python files, they are Git-friendly, executable as scripts, and easy to integrate into your existing Python projects.

Changes to bundled plugins in 2026.2

As part of ongoing maintenance, we are unbundling and deprecating low-usage plugins, including Data Wrangler, Hugging Face, and Google Colab support. You can continue to install compatible versions from JetBrains Marketplace, but these plugins are no longer bundled or actively maintained by the PyCharm team. A more focused set of bundled plugins means a leaner codebase, helping us keep PyCharm fast and responsive and invest our effort where it has the most impact.

Redesigned Python Packages tool window

• Packages now appear in a collapsible tree alongside their dependencies so you can see what’s installed and why – with new icons, right-aligned versions, and inline Install/Update links.
• A new floating search popup (think “Search Everywhere” but for packages) makes finding and installing fast. It also shows you which environment will be used and lets you pick a module and dependency group.
• You can install a package into specific uv/Poetry dependency groups like dev or test per workspace member, change versions inline or through the new Change Version dialog, and install from VCS via Custom Installation.
• Package repositories can be enabled or disabled, with state remembered across sessions. In addition, unreachable URLs show a clear error, and Remote Development support is substantially improved.

Clearer type checking

Get clearer, more actionable type messages:

• Richer type-mismatch errors, now with a breakdown of why the types don’t match.
• A type diff for callables and other composite types, so both sides read the same way.
• Fully rendered names and types in inspection tooltips, with clickable links.

Bug fixes

• Virtual environments for end-of-life Python: PyCharm no longer creates venvs for Python 2.7, 3.6, and 3.7. You can still create a new env from a command line and add it to the IDE manually.
• SQLAlchemy 2.0 Session.get() inference: Session.get(Entity, id) (and SQLModel) is now inferred as a model instance rather than the class.

Download PyCharm

All of these updates are available in PyCharm 2026.2.1. Update right from the IDE or the Toolbox App, or download the latest version to try everything out on your own projects. As always, we’d love to hear your feedback.
