✨ New & Improved

Area	What’s new
Type Checking	- Limit the width of inferred return types to prevent large unions. - Comparison checks involving Any now yields Any (not bool), matching gradual typing expectations and avoiding overly-confident boolean results
Language Server	- IDE diagnosticMode now includes an experimental workspace mode. When set to workspace, Pyrefly publishes diagnostics for all files in a project once any file from that project is opened. - Support added for the TSP typeServer/getPythonSearchPaths message. - Relative imports now work for go-to-definition and completions (including site-packages), reducing “can’t resolve import” / missing navigation cases
Type Errors	- Default severities have been tuned to reduce noise: implicit-import errors downgraded to warning; unreachable and redundant-condition errors default to warning (are configurable back to errors if desired) - New error code `non-convergent-recursion`, read the docs
Performance Improvements	- Added dedicated thread pool for LSP operations to prevent blocking main thread during rechecks
