• Improved generic type checking launched in v0.140. The deprecated implementation and the temporary generate_tests=true flowconfig option have now been removed.
• Fixed an issue with logical operators (&&, ||, ??) and union types
• Object rest properties (let {foo, ...rest} = obj) now retain the indexer of the object being destructured. In this example, if obj is {[string]: string}, then rest is also {[string]: string}.
• Made the parser recover gracefully in some cases when in the middle of typing, allowing language services to work better in the rest of the file
• Improved experimental cross-module autocomplete to include globals and built-in modules. Can be enabled with the autoimports=true flowconfig option.
• Fixed a bug so that the server no longer exits when merely touch-ing the .flowconfig without changing it
