2.10.8

• Change dispatching of availability states in case an availability
  handler of a service instance is blocked in user code: Availability
  states of a service instance are now never dispatched parallel. The
  next availability state for a service instance is only dispatched
  after the blocked availability handler returned from user code. If
  the availability of the service instance changes in the meantime,
  subsequent incoming messages of the service instance are queued
  until the availability change was reported to the user code.
• Subscriptions to remotely offered services are now always done based
  on the protocol(s) the remote service is offered with. The
  subscription_type parameter of the application::subscribe method is
  ignored.
• Added wildcard support ("any") for the uid and gid json parameters
  in the security configuration.
• Fix possible deadlock on application shutdown
