Currently two languages are supported for Bamboo Specs, Java and YAML. However, the implementation of these are not equal as the Java side is enabled to work with multiple bamboo plans where the YAML side is restricted to just one.
As we're a non-java shop currently we prefer the YAML side as it simplifies the technology stack (ansible using YAML as well).
When will the YAML side be upgraded to keep in sync feature-wise with the Java side?
