Fixed issues and improvements

For a list of fixed issues and improvements made for this release, see the following

Deprecated features

Following features are deprecated in this release and will be removed in the next release.

  • Management Console (This will be replaced with an alternative monitoring mechanism in a future release)
  • MSF4J profile (In the future we see more value to users from the WSO2 MSF4J GitHub project and its artifacts. This is because most of the microservice developers use it as a dependency rather than a server runtime. So it is our understanding that MSF4J is more useful to developers in its GitHub-based release cycle rather than packaging it in WSO2 Enterprise Integrator).
  • Priority Executors, Enqueue Mediator
  • Bean Mediator
  • POJO Command Mediator
  • Conditional Router Mediator
  • In and Out Mediators
  • Event Mediator and In memory Topics
