[dependabot]

Bumps ty from 0.0.68 to 0.0.69.

Release notes

Sourced from ty's releases.

0.0.69

Release Notes

Released on 2026-08-06.

Core type checking

• isinstance narrowing for generic classes is now more gradual by default (#27308)

  This new behavior is more similar to what other major type checkers do. For example:

  def f(xs: object):
      if isinstance(xs, list):
          reveal_type(xs)  # now: `list[Unknown]`, before: `Top[list[Unknown]]`

  Note: you might consider enabling analysis.strict-generic-narrowing if you prefer the strictly correct behavior.
