Changelog

Sourced from helmet's changelog.

8.3.0 - 2026-07-11

Changed

• Content-Security-Policy: improved performance by ~7% when there are no dynamic directives
• Content-Security-Policy: improved error handling for invalid directive names

Fixed

• Content-Security-Policy: useDefaults: false with no directives is no longer valid, both at runtime and the type level
• Content-Security-Policy: dynamically-computed directive values would throw, not call next, when invalid
• Content-Security-Policy: dynamically-computed directive value entries would throw, not call next, when function threw

8.2.0 - 2026-05-21

• Cross-Origin-Opener-Policy: support noopener-allow-popups. See #522
• Improve error message when passing duplicate options

8.1.0 - 2025-03-17

Changed

• Content-Security-Policy gives a better error when a directive value, like self, should be quoted. See #482

8.0.0 - 2024-09-28

Changed

• Breaking: Strict-Transport-Security now has a max-age of 365 days, up from 180
• Breaking: Content-Security-Policy middleware now throws an error if a directive should have quotes but does not, such as self instead of 'self'. See #454
• Breaking: Content-Security-Policy's getDefaultDirectives now returns a deep copy. This only affects users who were mutating the result
• Breaking: Strict-Transport-Security now throws an error when "includeSubDomains" option is misspelled. This was previously a warning

Removed
