Hugo 0.67.0: Custom HTTP headers

The two main items in Hugo 0.67.0 is custom HTTP header support in hugo server and include/exclude filters for Hugo Deploy.

Being able to configure HTTP headers in your development server means that you can now verify how your site behaves with the intended Content Security Policy settings etc., e.g.:

server:
  headers:
  - for: /**.html
    values:
      Content-Security-Policy: script-src localhost:1313
      Referrer-Policy: strict-origin-when-cross-origin
      X-Content-Type-Options: nosniff
      X-Frame-Options: DENY
      X-XSS-Protection: 1; mode=block

[server]
[[server.headers]]
  for = '/**.html'
  [server.headers.values]
    Content-Security-Policy = 'script-src localhost:1313'
    Referrer-Policy = 'strict-origin-when-cross-origin'
    X-Content-Type-Options = 'nosniff'
    X-Frame-Options = 'DENY'
    X-XSS-Protection = '1; mode=block'

{
   "server": {
      "headers": [
         {
            "for": "/**.html",
            "values": {
               "Content-Security-Policy": "script-src localhost:1313",
               "Referrer-Policy": "strict-origin-when-cross-origin",
               "X-Content-Type-Options": "nosniff",
               "X-Frame-Options": "DENY",
               "X-XSS-Protection": "1; mode=block"
            }
         }
      ]
   }
}
