+- Specify execution order for System `PreUpdate` and `Update` callbacks
+  ([gz-sim#2487](https://github.com/gazebosim/gz-sim/pull/2487),
+  [gz-sim#2500](https://github.com/gazebosim/gz-sim/pull/2500)).
+
+  - While the `PreUpdate`, `Update`, and `PostUpdate` phases of gz-sim systems
+    allow some control over the order in which code is executed, there are
+    cases in which more control is desired. For example, the `UserCommands`
+    system can create new models during its `PreUpdate` callback in response
+    to `EntityFactory` messages (see the
+    [entity creation tutorial](https://gazebosim.org/api/sim/9/entity_creation.html)),
+    and that callback should happen before any other system callbacks that
+    expect to operate on all entities in the scene. Now, the order of execution
+    for `PreUpdate` and `Update` callbacks for a System can be specified using
+    an integer priority value, with smaller values executing first.
+    The default system priority can be specified at compilation time by
+    implementing a new `SystemConfigurePriority` interface in that system,
+    and the priority can be overridden by specifying an XML parameter in the
+    system's SDFormat `<plugin/>` tag.
+  - Constant priority values have been defined in
+    [gz/sim/System.hh](https://github.com/gazebosim/gz-sim/blob/gz-sim9_9.0.0-pre1/include/gz/sim/System.hh#L106-L129)
+    for the `Physics` and `UserCommands` systems to ensure that
+    `UserCommands::PreUpdate` and `Physics::Update` execute before other
+    system callbacks with default priority.

+- Improve determinism of ForceTorque sensor
+  ([gz-sensors#449](https://github.com/gazebosim/gz-sensors/pull/449),
+  [gz-sim#2487](https://github.com/gazebosim/gz-sim/pull/2487),
+  [gz-sim#2494](https://github.com/gazebosim/gz-sim/pull/2494),
+  [gz-sim#2500](https://github.com/gazebosim/gz-sim/pull/2500)).
+
+  - The wrenches measured by ForceTorque sensors are now written to the ECM
+    in addition to publishing to a gz-transport topic, offering a more
+    deterministic data path for sensor data.
+  - Writing sensor data to the ECM required moving the sensor update from the
+    `PostUpdate` callback, which allows read-only access to the ECM with
+    parallel execution, to the `Update` callback, which allows write-access to
+    the ECM with sequential execution. It also uses the system execution order
+    priority to ensure that the ForceTorque `Update` callback occurs after
+    the `Physics` system `Update`.
