A future version of Go may change the defaults to
`tarinsecurepath=0` and `zipinsecurepath=0`.

Go 1.20 introduced automatic seeding of the
[`math/rand`](/pkg/math/rand) global random number generator,
controlled by the [`randautoseed` setting](/pkg/math/rand/#Seed).

Go 1.20 introduced the concept of fallback roots for use during certificate verification,

addition to default policies [readonly|readwrite|writeonly|consoleAdmin|diagnostics] ## you can define additional policies with custom supported actions and resources policies: [] ## writeexamplepolicy policy grants creation or deletion of buckets with name ## starting with example. In addition, grants objects write permissions on buckets starting with ## example. # - name: writeexamplepolicy # statements: # - resources: # - 'arn:aws:s3:::example*/*' # actions: # - "s3:AbortMultipartUpload" # - "s3:GetObject"...

Puedes aprender más en la **Guía de Usuario Avanzada** sobre cómo usar "scopes" de OAuth2, para un sistema de permisos más detallado, siguiendo estos mismos estándares. OAuth2 con scopes es el mecanismo utilizado por muchos grandes proveedores de autenticación, como Facebook, Google, GitHub, Microsoft, X (Twitter), etc. para autorizar aplicaciones de terceros para interactuar con sus APIs en nombre de sus usuarios....
