facebook/flow v0.136.0

on GitHub

Likely to cause new Flow errors:

• Flow now raises errors when generic type variables escape out of the scope in which they were defined.

Notable bug fixes:

• Fix a race condition related to saved state and cancelable rechecks that caused internal errors of Requires_not_found or Sig_requires_not_found.

Misc:

• Added documentation to core.js builtins.
• Add optional propTypes to React.AbstractComponentStatics (thanks @Brianzchen).
