v0.46.1

This is bugfix release to resolve an issue in the release pipeline. Everything else is the same as 0.46.0, which contains a mix of bugfixes, optimizations, and new features:

New language feature: refs in rule heads

With this version of OPA, we can use a shorthand for defining deeply-nested structures in Rego:

Before, we had to use multiple packages, and hence multiple files to define a structure like this:

{
  "method": {
    "get": {
      "allowed": true
    }
    "post": {
      "allowed": true
    }
  }
}

package method.get
default allowed := false
allowed { ... }

package method.post
default allowed := false
allowed { ... }

Now, we can define those rules in single package (and file):

package method
import future.keywords.if
default get.allowed := false
get.allowed if { ... }
default post.allowed := false
post.allowed if { ... }

Note that in this example, the use of the future keyword if is mandatory
