KrakenD Enterprise is excited to announce the release of its API gateway software v2.3, available for download. This upgrade delivers an improved experience for users looking to simplify their operations.

With KrakenD v2.3, users will experience greater simplicity, eliminating the need for several plugins and adding automated processes to import OpenAPI and gRPC contracts.

This upgrade has been designed to address the joint pain points customers experience when managing their APIs.

Simplifying Operations with KrakenD Enterprise

We’ve heard you, and we’ve acted. With KrakenD v2.3, you’ll experience simplicity like never before. No more fumbling for the wildcard, gRPC, redirect, or web proxy functionalities - no plugins needed anymore!

For instance, use the /path/to/* syntax for easier wildcards instead of adding the server and client plugins mix, or create a catalog of proto files and add automatic gRPC backends.

End-to-end testing has been made easier with JSON Schema definition tests, and the multiple merge of OpenAPI contracts lets you import numerous contracts in a single operation. Plus, there’s a new OpenAPI serve command to start a KrakenD server from an OpenAPI file; no import is required.

Example of wildcard simplification: Before and After.

Resolving Your Pain Points

Our mission is to make your API management as seamless as possible. The new version includes NTLM authentication for legacy Microsoft Dynamics ERP.

Adding service-to-service authentication flow on Google Cloud and shared caching of JWK URLs enhances your security and efficiency, so you can stop managing these pieces on your own.

Finally, KrakenD Designer allows you to apply changes on a local KrakenD directly from the web.

Enhancements and Fixes

We’re always looking for ways to improve KrakenD, and we implement functionalities our customers ask for. For example, the New Relic integration now accepts additional headers to report. The new back-off strategies for AMQP make an easier administration. The API key functionality adds support for legacy API keys that don’t add a Bearer or Basic indication and per-endpoint strategy override as well. The Security Policies engine adds bitwise operations. All these new functionalities were requested by Enterprise customers.

We’ve also made several fixes, including support for JMESpath for json.Number or previous problems with WebSockets and forced Gzip, or the upgrade to Go version 1.20.4, which ensures an even safer environment with crypto packages’ security fixes.

In essence, KrakenD Enterprise v2.3 is a product of our commitment to providing you with an easy-to-use, efficient, and secure API management solution. So gear up for a hassle-free API journey with KrakenD v2.3!

Deprecation notes and migration instructions

All deprecated components continue to work as usual in v2.3, but they will be removed in future versions, so we encourage you to make the changes now.

The no-redirect and http-proxy plugins are now considered deprecated. Instead, you have the same functionality more conveniently through the native HTTP Client options component that handles all these functionalities together and frees the usage of HTTP client plugins for other usages.

The OpenAPI functionality adds a new command that defaults to OpenAPI 3, and the previous one continues to work in this version.
