# Upgrade to 3.0.0

CBSecurity 3 is a major release and it will require some updates in order for you to fully upgrade your previous versions.

## JwtService Validator Deprecated

In the previous releases the validator for JWT was `JwtService@cbsecurity`. This has now changed to `JwtAuthValidator@cbsecurity`. So make sure you update your configurations.

## CBAuthValidator Deprecated

The `CBAuthValidator` has been renamed to just `AuthValidator`. This validator is now not `cbauth` focused but `IAuthService` focused. It also supports role and permission based authorization.

## Settings Structure

The entire settings structure has been redesigned to support many features in a a more concise and block approach. All top-level settings have been removed and added to specific sections. Please review the [Configuration](/getting-started/configuration.md) section in detail to see where the new settings belongs to.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://coldbox-security.ortusbooks.com/readme/upgrade-to-3.0.0.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
