This release introduces powerful new features for API management including
internal route invocation and improved authentication policies.

### Breaking Changes 🛠

- Removed the deprecated Aserto authorization policy due to
  [Aserto shutting down](https://www.aserto.com/blog/the-final-chapter-for-aserto).
  If you're currently using this policy, please migrate to an alternative
  authorization solution.

### New Features 🎉

- **Internal Route Invocation**: Added `context.invokeRoute` capability that
  allows you to internally invoke a route without making an external HTTP
  request. This enables more efficient internal API calls and better performance
  for complex routing scenarios.

- **Enhanced Client IP Parsing**: Improved parsing of client IP addresses from
  the X-Forwarded-For header, providing more accurate client identification for
  rate limiting and analytics.

- **CLI Log Verbosity Control**: Added a new flag to control log verbosity
  levels in the Zuplo CLI, making debugging and troubleshooting easier during
  local development.

- **Custom Domain Aliases**: Introduced support for custom domain aliases,
  allowing you to map multiple domains to a single API deployment for more
  flexible domain management.

- **Web Bot Authentication**: New policy for authenticating and managing web bot
  traffic, helping you control automated access to your APIs.
  [See the policy docs for more details](https://zuplo.com/docs/policies/web-bot-auth-inbound)

- **API Key Management Enhancement**: You can now delete the default API key,
  providing more flexibility in API key lifecycle management.
  [See documentation](https://zuplo.com/docs/articles/accounts/default-api-key)

### Bug Fixes 🐛

- Fixed an issue that prevented changing deployments for custom domains.
- Increased the body size limit on GitHub webhooks to support larger payloads.
- Enhanced error handling in mock API policy to support single example
  responses.

### Documentation 📚

- Updated documentation for the
  [Auth0 JWT authentication policy](https://zuplo.com/docs/policies/auth0-jwt-auth-inbound).
