| ## Release Notes |
| |
| ## Apache ServiceComb Java-Chassis (Incubating) 1.0.0-m1 |
| |
| ### Major improvements: |
| |
| - Java Chassis can now use Apollo as configuration center. Users can now |
| change configurations like load balancing policy and those changes will |
| come into effect on the fly. |
| See [here](http://servicecomb.apache.org/users/dynamic-config/) for more |
| details. |
| |
| - Metrics was re-factored. We now uses events for collecting invocation data |
| instead of Hystrix. This reduces the performance penalty of computing |
| metrics. |
| Metrics can now be fetched via '/metrics' using HTTP. |
| See [here](http://servicecomb.apache.org/users/metrics-in-1.0.0-m1/) for |
| more details. |
| |
| ### Other Noticeable Changes: |
| |
| - The Java Chassis libraries are now under group "org.apache.servicecomb". |
| - We provide out of the box metrics support now. Prometheus is supported. |
| - Configuration center was re-factored and moved out from foundation. |
| Support for Apollo was added. |
| - Users can now use Object type for calling services. |
| - Users can now use Generics for calling services. |
| - Better integration with Spring MVC. |
| - Upgraded to zipkin2 internally, Java Chassis can now work with zipkin |
| server v1 and v2. |
| - We are in the process of supporting reactive programming. Pojo consumer |
| and provider now supports CompletableFuture. |
