WireMock 3.13.0 Released

The WireMock team is excited to announce the release of WireMock version 3.13.0. This release includes quite a few new features, a number of bug fixes and the usual dependency updates. See the changelog for more details.

Next Steps

If you haven’t yet updated to WireMock 3.x, this is an excellent opportunity to do so! You can download the standalone jar directly from our website and if you use Docker, the official docker images have been updated. For the dependencies in your code, WireMock 3.13.0 can now be found in Maven Central

Please feel free to reach out to us on the WireMock Community Slack channel if you need any assistance.

WireMock Version 4

The WireMock team is now looking past the 3.x releases to what version 4 of WireMock might look like. We are in the process of releasing the first 4.x beta versions. The beta versions are under active development and we recommend you try them out. We would love to hear your feedback on the WireMock Community Slack.

We have given this release a beta label due to the fact that as we move forwards with the 4.x release there will be breaking changes. These are the current updates to the 4.x release:

  • Java 17 is now the baseline java version
  • Jetty 12 is shipped by default so there is no longer a specific jetty 12 release of 4.x and Jetty 11 is no longer supported.
