2.1.0

New features:

• forbidCast: denies casting you configure - by default only (object), (array) and (unset)
• enforceNativeReturnTypehint: enforces usage of native return typehints if supported by your PHP version
• forbidPhpDocNullabilityMismatchWithNativeTypehint: denies invalid phpdocs without null when native type contains null
• forbidNullInInterpolatedString: disallows using nullable expressions within double-quoted strings like "Hi $name!"

Fixes:

• forbidUnusedMatchResult: Do not report if all arms contain assignment.

Dependencies:

• phpstan/phpstan now requires at least 1.8.7 (was 1.8.1, see #69)
• nikic/php-parser now requires at least 4.14.0 (was 4.13.2, see #69)
