+- [4299](https://github.com/Azure/azure-cosmos-dotnet-v3/pull/4299) Query: Adds environment variable for overriding EnableOptimisticDirectExecution default (#4299)
+  > Note: This change provides another way to manage the upgrade to `3.38`. It provides an option to avoid potential disruption due to the breaking change (see the note below) if only config deployment is preferred, instead of any explicit code modification.
+  > With this change, users can set the environment variable AZURE_COSMOS_OPTIMISTIC_DIRECT_EXECUTION_ENABLED to false in their production environments while upgrading from previous minor version (`3.37` or below) to `3.38.1` (or above).
+  > This will signal the SDK to disable Optimistic Direct Execution by default.
+  > Once the environment is fully upgraded to the target version, the environment variable can be removed (or set to true) to enable ODE.
+  > It is recommended that the environment variable is used only to manage the upgrade and removed once the deployment is complete.
+  > Please note that environment variable acts as the override only for choosing the default value. If the code explicitly modifies the setting, that value will be honored during actual operations.
