The most relevant features for the 0.7 release are increased metrics and tracing options, and functionality that has been requested by many, the sequential proxy merger. During this release, we also updated the KrakenD brand with a new logo, and we added more documentation.

On the metrics side, we can now send structured events using GELF to your Graylog Cluster. Opencensus middleware adds new functionality to push metrics to your Google StackDriver account.

The sequential proxy merger is a mechanism that allows you to use cascading calls with your backends to feed endpoints. Meaning that you can call backends, capture the output fields, and use them as the input of subsequent backend queries.

The Krakend Playground and the KrakenDesigner (UI) are also updated.

KrakenD framework

The KrakenD framework continues being stable and complete for the evolution of the gateway. The changes added are:

  • Default configuration parser accepts now custom file readers. File formats accepted:
    • .json
    • .toml
    • .yaml
    • .yml
    • .properties
    • .props
    • .prop
    • .hcl
  • Replace the http package by transport. Getting ready for gRPC? (oops, spoiler)
  • Do not close a nil body (on the proxy layer)
  • Expose the HTTP server construction
  • Delay endpoint method sanitization until required
  • Sequential proxy merger
  • Add error details into the HTTP response
  • Bugfix: HTTP client timeout was set to 15 maximum seconds (no limit now)
  • Updated brand, new logo!

Between 0.6 and 0.7, we have published an intermediate release 0.6.1 with:

  • Support for HTTP2/HTTPS
  • FIX: query string parameters works now with arrays and repeated variables (e.g.: ?a[]=a1&a[]=a2&b=b1&b=b2)
  • Added Go 1.11 to the build matrix
