This build focuses on expanding core type system capabilities, optimizing ecosystem integrations like uv and Pyright, and enhancing overall IDE stability: Code insight and type checking

• Assign string variables and get accurate Literal type evaluations from the type checker without incorrect type leaks - PY-46450.
• Rely on accurate type inference across complex, multi-variable iterable unpacking sequences - PY-43585, PY-27205, and PY-89977.
• Use the new lazy import keyword with full coding assistance and type checking support for PEP 810 syntax compliance - PY-88664.
• Generate core setups instantly using new built-in completion templates for @dataclass, Enum, and TypedDict structures - PY-84226. LSP and external tools
• Configure typing tools precisely with newly separated, independent environment settings for Pyright and Basedpyright - PY-90401. Interpreter and package management
• Use custom script paths and Windows .bat wrappers as fully functional project interpreters - PY-89236.
• Synchronize and resolve multi-project dependencies across nested monorepos using improved uv tool parsing - PY-89677 and PY-90207. Jupyter notebooks and frameworks
• Increase workspace scales past 100% inside Jupyter Notebooks without breaking cell boundaries or inflating text areas out of proportion - PY-85890.
• Keep execution details in clear view without the final cell output randomly vanishing from the bottom of a notebook - PY-90321.
• Use the Open Table Documentation action from the DataView layout without hitting dead or broken URLs - PY-88390. Debugger and runtime stability
• Terminate active debug sessions completely as the debugpy engine now ensures all spawned background subprocesses close alongside it - PY-90340.
• Run execution sessions securely on macOS without runtime pycache drops invalidating the signed app bundle signature - PY-90668.
• Launch complex pytest configurations smoothly with macros expanding perfectly right at execution startup - PY-90680.
