Tyk Dashboard v4.1

Last updated: 4 minutes read.

Release Highlights

OpenAPI as a native API definition format

Tyk has always had a proprietary specification for defining APIs. From Tyk v4.1 we now support defining APIs using the Open API Specification (OAS) as well, which can offer significant time and complexity savings. This is an early access capability.

As we extend our OAS support, we would very much like your feedback on how we can extend and update to best meet your needs: .

This capability is available in both the open source and paid versions of Tyk. See our High Level Concepts for more details, or jump to OAS Getting Started documentation.

MDCB Synchroniser

Tyk Gateway v4.1 enables an improved synchroniser functionality within Multi Data Centre Bridge (MDCB) v2.0. Prior to this release, the API keys, certificates and OAuth clients required by worker Gateways were synchronised from the controller Gateway on-demand. With Gateway v4.1 and MDCB v2.0 we introduce proactive synchronisation of these resources to the worker Gateways when they start up.

This change improves resilience in case the MDCB link or controller Gateway is unavailable, because the worker Gateways can continue to operate independently using the resources stored locally. There is also a performance improvement, with the worker Gateways not having to retrieve resources from the controller Gateway when an API is first called.

Changes to keys, certificates and OAuth clients are still synchronised to the worker Gateways from the controller when there are changes and following any failure in the MDCB link.

Go Plugin Loader

When upgrading your Tyk Installation you need to re-compile your plugin with the new version. At the moment of loading a plugin, the Gateway will try to find a plugin with the name provided in the API definition. If none is found then it will fallback to search the plugin file with the name: {plugin-name}_{Gw-version}_{OS}_{arch}.so

From v4.1.0 the plugin compiler automatically names plugins with the above naming convention. It enables you to have one directory with different versions of the same plugin. For example:

  • plugin_v4.1.0_linux_amd64.so
  • plugin_v4.2.0_linux_amd64.so

So, if you upgrade from Tyk v4.1.0 to v4.2.0 you only need to have the plugins compiled for v4.2.0 before performing the upgrade.



  • Added support for new OAS api definition format, and new API creation screens
  • Dashboard boostrap instalation script extended to support SQL databases
  • Added TYK_DB_OMITCONFIGFILE option for Tyk Dashboard to ignore the values in the config file and load its configuration only from environment variables and default values
