# What's New in PyCharm 2026.2.1

**[JetBrains](https://daily.dev/sources/jetbrains)** · 4 min read · 0 upvotes · 0 comments

## Summary

PyCharm 2026.2.1 lets AI agents like Claude Code and Codex work directly inside Jupyter notebooks against a live kernel, preserving variables and models across cells. A new agent environment coordinator ensures agents target the correct Python interpreter and tool (uv, Poetry, pip, conda) instead of a system environment. The release also adds a third-party marimo notebooks plugin, redesigns the Python Packages tool window with a collapsible dependency tree and search popup, improves type-mismatch error messages, and unbundles low-usage plugins (Data Wrangler, Hugging Face, Google Colab support). Bug fixes include blocking venv creation for end-of-life Python versions (2.7, 3.6, 3.7) and fixing SQLAlchemy 2.0 Session.get() type inference.

## Questions this post answers

### Does PyCharm 2026.2.1 let AI agents like Claude Code work directly inside Jupyter notebooks?

Yes, PyCharm 2026.2.1 introduces a Jupyter notebook skill that lets AI agents such as Claude Code and Codex create, edit, and run .ipynb notebooks through PyCharm's notebook model against a live kernel. This means variables, models, and data persist across cells rather than disappearing when the agent runs disconnected scripts, resulting in more reliable notebook work with fewer tokens used. It requires a JetBrains AI subscription.

### How does PyCharm 2026.2.1 stop AI agents from installing packages into the wrong Python environment?

A new agent environment coordinator skill gives the AI agent the project's configured interpreter and tool (uv, Poetry, pip in a venv, or conda) so commands target the correct environment instead of a system one. If no environment exists yet, the agent can set one up via PyCharm itself, then decides how to use that information when installing or running commands. It also requires a JetBrains AI subscription.

### Does PyCharm still create virtual environments for Python 2.7 or 3.6?

No, PyCharm 2026.2.1 no longer creates virtual environments for end-of-life Python versions 2.7, 3.6, and 3.7. Developers who still need one of these environments can create it manually from the command line and then add it to the IDE afterward rather than relying on PyCharm's built-in environment creation.
