 - Refined error messages for serviced-based evaluators and simulators.
 - Introduced environment variable `AI_EVALS_DISABLE_EXPERIMENTAL_WARNING` to disable the warning message for experimental features.
 - Changed the randomization pattern for `AdversarialSimulator` such that there is an almost equal number of Adversarial harm categories (e.g. Hate + Unfairness, Self-Harm, Violence, Sex) represented in the  `AdversarialSimulator` outputs. Previously, for 200 `max_simulation_results` a user might see 140 results belonging to the 'Hate + Unfairness' category and 40 results belonging to the 'Self-Harm' category. Now, user will see 50 results for each of Hate + Unfairness, Self-Harm, Violence, and Sex. 
+- For the `DirectAttackSimulator`, the prompt templates used to generate simulated outputs for each Adversarial harm category will no longer be in a randomized order by default. To override this behavior, pass `randomize_order=True` when you call the `DirectAttackSimulator`, for example:
+```python
+adversarial_simulator = DirectAttackSimulator(azure_ai_project=azure_ai_project, credential=DefaultAzureCredential())
+outputs = asyncio.run(
+    adversarial_simulator(
+        scenario=scenario,
+        target=callback,
+        randomize_order=True
+    )
+)
+```
