Release Notes

Released on 2026-04-28.

Notable changes

• ty now prefers the declared type of an annotated assignment in more situations (#24802). Consider this example:

  from some_library import untyped_function
  threshold: int | None = 0
  result: str = untyped_function()

  ty previously favored the inferred type of the right hand side expression when threshold and result were used. This is useful for threshold, as it allows something like threshold += 1 to work without an error: we know that threshold could later become None, but right now, we see that it is an int. However, for result, the inferred type is Unknown. This is not a useful type and it can lead to false negatives. Starting with this release, ty will therefore prefer the declared type if the inferred and declared types are mutually assignable. In the above example, threshold will still be inferred as int (or rather Literal[1]), but result will now be inferred as str. If you previously added casts to work around this behavior, you should be able to remove them after upgrading.

Bug fixes

• Fix reporting of annotation-only locals as unused (#24811)
• Fix project and workspace selection (#24824)
• Fix go-to definition for generic classes (#24714)
• Fix receiver coloring for aliased decorators (#24884)

LSP server

• Add support for go-to definition in literal enum member inlay hints (#24792)
• Add support for "baking" keyword argument inlay hints into the source code (#24667)
• Don't allow inlay hint edits when introducing a non global scope symbol (#24797)
• Omit semantic highlighting for unresolved symbols (#24718)

Core type checking

• Support narrowing with aliased conditional expressions (#24302)
• Model short-circuiting control flow in Boolean expressions (#24458)
• Handle finally blocks where all try/except blocks are terminal (#24882)
• Detect invalid ClassVar vs instance-attribute overrides (#24767)
• Emit diagnostic for invalid uses of Unpack[...] (#24868)
• Infer lambda parameter types with Callable type context (#24317)
• Support ** unpacking of TypedDict in dict-literal assignments (#24703)
• Support Unpack[TypedDict] in **kwargs signatures (#24653)
• Treat [*xs] as an irrefutable pattern when matching on Sequence (#24787)
• Improve generics solving for unions in invariant positions (#24698)
• Improve generics solving for unions when matching against protocols (#24837)

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
