- 3fd69e7: Merge pull request Netflix#927 from chrisgray/chrisgray/dashboard_iscircuitbreakeropen
- ff5d4cf: [hystrix-dashboard] isCircuitBreakerOpen is a normally a boolean from the HystrixStream servlet, however these replace() operations assume that it is a string. There are certain instances where Turbine does not return back a String when isCircuitBreakerOpen is aggregated. This enforces the boolean to be a string first, regardless of what Turbine may/may not do.
