Changelog

Sourced from helmet's changelog.

6.0.0 - 2022-08-26

Changed

• Breaking: helmet.contentSecurityPolicy no longer sets block-all-mixed-content directive by default
• Breaking: helmet.expectCt is no longer set by default. It can, however, be explicitly enabled. It will be removed in Helmet 7. See #310
• Breaking: Increase TypeScript strictness around some arguments. Only affects TypeScript users, and may not require any code changes. See #369
• helmet.frameguard no longer offers a specific error when trying to use ALLOW-FROM; it just says that it is unsupported. Only the error message has changed

Removed

• Breaking: Dropped support for Node 12 and 13. Node 14+ is now required
