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:

  deff(xs: object):
  ifisinstance(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.
