1.16.0 — Change History & AI cost visualisation

Change History. Every save to a test (and to an execution plan) now produces a version entry with field-level diffs, so you can see what changed and when. See Change History.

AI cost visualisation. The Dashboard and the execution overview now show the actual AI cost of executions, not only the raw token consumption. See Home.

Snippets imported as individual objects from Xray. Xray Call Test references now produce real, individually-imported snippets in msg.ZenTestAI and stay synchronized — existing snippets are reused automatically. See External Systems → Snippets and external systems and Reusability — Snippets.

Integration stability. Better support on the msg side for BMW density, React Aria and SAP WebGUI.
