facebook/flow v0.307.0

on GitHub

Notable bug fixes:

• Support numeric literal object keys when importing/exporting object literals
• Allow type keywords like infer to appear as member names in qualified type access (e.g. type S = O.infer;).
• Allow type keywords (readonly, keyof, infer, etc.) as function type parameter names

Parser:

• It is now a parse error to have a ? optional modifier in various places this does not make sense, e.g. const x? = 1;

Misc:

• API change: flow check becomes an alias of flow status. You can use flow full-check to trigger a full foreground check of a Flow root.
