• Fix an issue with [include] entries containing both globs and relative paths on Windows
• Fix crash when declaring a destructured binding in a library definition
• Fix missing autocomplete results for JSX component properties when the component's type is recursive
• Fix analysis of unreachable += expressions
• Fix incremental typechecking bug when adding files in Haste mode

Parser:

• Fix parser exception when parsing export interface ... or export enum ...
