[dependabot[bot]]

Bumps helmet-csp from 2.7.1 to 3.1.0.

Changelog

Sourced from helmet-csp's changelog.

3.1.0 - 2016-11-03

Added

• csp now allows frame-src directive

3.0.0 - 2016-10-28

Changed

• csp will check your directives for common mistakes and throw errors if it finds them. This can be disabled with loose: true.
• Empty arrays are no longer allowed in csp. For source lists (like script-src or object-src), use the standard scriptSrc: ["'none'"]. The sandbox directive can be sandbox: true to block everything.
• false can disable a CSP directive. For example, scriptSrc: false is the same as not specifying it.
• In CSP, reportOnly: true no longer requires a report-uri to be set.
• hsts's maxAge now defaults to 180 days (instead of 1 day)
• hsts's maxAge parameter is seconds, not milliseconds
• hsts includes subdomains by default
• domain parameter in frameguard cannot be empty

Removed

• noEtag option no longer present in noCache
• iOS Chrome connect-src workaround in CSP module

2.3.0 - 2016-09-30

Added

• hpkp middleware now supports the includeSubDomains property with a capital D

Fixed

• hpkp was setting includeSubdomains instead of includeSubDomains

2.2.0 - 2016-09-16

Added

• referrerPolicy middleware

2.1.3 - 2016-09-07

Changed

• Top-level aliases (like helmet.xssFilter) are no longer dynamically required

Deprecated
