Today the minimum version of VCL available across our network increased, unlocking the following changes:

## Improved content

- `subfield()` updated to note that it cannot be used on a `Set-Cookie` header
- `uuid.version4()` documentation was incorrectly showing the definition of a different function, and has been updated
- Documentation for `client.ip`, `fastly_info.state`, and `obj.hits` has been significantly updated and expanded

## New functions

- `querystring.get`
- `setcookie.delete_by_name`
