Breaking changes in Unity

Breaking changes in Unity will be handled as follows:

  • Changes that require a change to the NServiceBus.Unity API (e.g. changes to IUnityContainer) will be released in a new major version of NServiceBus.Unity.
  • Changes that do not require a change to the NServiceBus.Unity API will be released as a patch release to the latest minor version of NServiceBus.Unity.
  • If Unity releases a new major version, it will be supported in a new minor release of NServiceBus.Unity.
