com.unity.ml-agents/CHANGELOG.md

  - Unused static methods from the `Utilities` class (ShiftLeft, ReplaceRange, AddRangeNoAlloc, and GetSensorFloatObservationSize) were removed.
  - The `Agent` class is no longer abstract.
  - SensorBase was moved out of the package and into the Examples directory.
+ - `AgentInfo.actionMasks` has been renamed to `AgentInfo.discreteActionMasks`.

docs/Migrating.md

 * The `SetMask` method must now be called on the `DiscreteActionMasker` argument of the `CollectDiscreteActionMasks` method.
 * The method `GetStepCount()` on the Agent class has been replaced with the property getter `StepCount`
 * The `--multi-gpu` option has been removed temporarily.
+* `AgentInfo.actionMasks` has been renamed to `AgentInfo.discreteActionMasks`.
 
 ### Steps to Migrate
 * Add the `using MLAgents.Sensors;` in addition to `using MLAgents;` on top of your Agent's script.
