Likely to cause new Flow errors:

• $ObjMap and $TupleMap become stricter. The following code now errors: example

IDE:

• Linked JSX editing will now only trigger if you edit the opening tag, instead of both the opening and the closing tag.
• We now provide IDE services in user-defined library definitions.

Notable bug fixes:

• Fixed a bug where recursive types defined across multiple files caused spurious errors and led to unsound types
• Add .databases() to IDBFactory (thanks @bobrovnikov)
• Mark DOMStringList as iterable, so that it works with Array.from(...) (thanks @bobrovnikov)
