This release introduces significant improvements to the Zuplo CLI, rate limiting
capabilities, and developer portal experience. Key highlights include a new CLI
command for migrating to the redesigned developer portal, enhanced rate limiting
with adaptive timeouts, and support for wildcard subdomains in CORS policies.

### New Features 🎉

- **New Developer Portal Migration Command** - Added
  `zuplo source migrate dev-portal` CLI command to help users migrate to the new
  [Zuplo Developer Portal](https://zuplo.com/docs/dev-portal/migration) built on
  the Zudoku framework. This simplifies the transition to the enhanced portal
  experience.

- **Enhanced Rate Limiting with Adaptive Timeouts** - The
  [rate limiter policy](https://zuplo.com/docs/policies/rate-limit-inbound) now
  supports adaptive and configurable timeouts, providing more flexible control
  over API rate limiting behavior and improved performance under varying load
  conditions.

- **CLI Project Creation** - New CLI command for creating Zuplo projects
  directly from the command line, streamlining the project setup workflow. See
  the [CLI documentation](https://zuplo.com/docs/cli/overview) for usage
  details.

### Bug Fixes 🐛

- **OpenAPI Transpiler Type Handling** - Fixed an issue where the
  [OpenAPI transpiler](https://zuplo.com/docs/handlers/openapi) now correctly
  defaults to "type: object" when properties are defined, ensuring proper schema
  generation and type safety.

- **CLI Tunnel Command Validation** - Added missing account argument validation
  for the create tunnel command in the
  [Zuplo CLI](https://zuplo.com/docs/cli/tunnels), preventing errors when
  setting up local development tunnels.

### Improvements 🔄

- **Wildcard Subdomain Support for CORS** - The
  [CORS policy](https://zuplo.com/docs/programmable-api/custom-cors-policy) now
  supports wildcard subdomains, enabling more flexible cross-origin
  configurations for APIs serving multiple subdomains or multi-tenant
  applications.

- **Enhanced SSO and MFA Security** - Improved security for enterprise accounts
  by enforcing SSO and MFA requirements, ensuring better access control and
  compliance with enterprise security policies.
