| 6.0.0-alpha |
| ------------------ |
| |
| SkyWalking 6 is totally new milestone for the project. At this point, we are not just a distributing |
| tracing system with analysis and visualization capabilities. We are an **Observability Analysis Platform(OAL)**. |
| |
| The core and most important features in v6 are |
| 1. Support to collect telemetry data from different sources, such as multiple language agents and service mesh. |
| 1. Extensible stream analysis core. Make SQL and cache analysis available in core level, although haven't |
| provided in this release. |
| 1. Provide **Observability Analysis Language(OAL)** to make analysis metrics customization available. |
| 1. New GraphQL query protocol. Not binding with UI now. |
| 1. UI topology is better now. |
| 1. New alarm core provided. In alpha, only on service related metrics. |
