Why atlassian latest SDK has only support confluenec server 9.0.3?

In the latest SDK for Confluence, which is listed on the market place, only the version 9.0.3 is supported, why does not the latest version? If I build a confluence macro using these SDKs, will the build run properly?

I had no problems using the SDK together with the newest confluence version - most of the stuff is handled by maven anyway and is pretty version agnostic
