• dict is not assignable to TypedDict (#21238)
• Allow values of type None in type expressions (#21263)
• Add narrowing for isinstance() and issubclass() checks that use PEP-604 unions (#21334)

• Support subscripting typing.Literal with a type alias (#21207)

LSP server

• Don't provide completions when in a class or function definition (#21146)
• For autocompletions, favor symbols defined in the current file over auto-imported symbols (#21194) and builtin symbols (#21285)

Diagnostics

• Add diagnostics for isinstance() and issubclass() calls that use invalid PEP-604 unions for their second argument (#21343)
• Don't assume in diagnostic messages that a TypedDict key error is about subscript access (#21166)

Other changes

• Consistently wrap tokens in parser diagnostics in backticks instead of 'quotes' (#21163)
• Discover the site-packages directory from the environment that ty is installed in (#21286), improving the ergonomics of uvx ty check
