   - Ability to set custom file where relay node log can be saved after tests run
   - Ability to set to set custom port for `chain-idex`
   - Ability to set custom directory for cluster data files
+  - Ability to set budget multiplier on estimated budget for rare case of incorrect estimation
 - Default cluster data files delivered via `data-files` package property
 - Contract execution result returns current contract state for failure cases too
 - Implementing tasty integration
