v0.196.0

Likely to cause new Flow errors:

• Instead of mixed, type the result of Object.values and Object.entries on a dictionary to be the dictionary values, and Object.entries keys to behave like Object.keys. Closes #2174, #2221, #4771, #4997, #5838.
• Ban array inputs to Object.values and Object.entries.
• Function's name and length property are now not writable.
• Fix Object.keys, $Values, and $Keys on interfaces with indexers.
• Delete $Subtype and $SuperType utilities.
• Delete deprecated-utility Flow lint.

New Features:

• An annotation is no longer required when exporting + expressions (e.g., export default (3 + 3 : number) can now just be export default 3 + 3;).

Notable bug fixes:

• Fix unary and binary arithmetic operations on bigints being exported/imported across modules as any or number.
• Fix autocomplete of string literals in bracket syntax, after a quote has already been typed.
• Improve sorting of results when autocompleting types.
• Boolean CLI flags must now be 1 or true to be truthy. Before, anything other than 0 and false was considered truthy.

Misc:

• Autocomplete results are now sorted case-insensitively.
• Autocomplete results are now sorted using a fuzzy score, in the same manner as VSCode.

Library Definitions:

• Add ReactSetStateFunction type alias in react. This is the type of setVal in const [val, setVal] = React.useState(...).
