 * The Mesos agent now requires the new `TASK_RESOURCE_LIMITS` feature. This capability is set by default, but if the `--agent_features` flag is specified explicitly, `TASK_RESOURCE_LIMITS` must be included.
+<a name="1-10-x-synchronous-authorization"></a>
+* Authorizers now must implement a method `getApprover(...)` (see the
+  [authorization documentation](
+  and [MESOS-10056](
+  that returns `ObjectApprover`s that are valid throughout their whole lifetime.
+  Keeping the state of an `ObjectApprover` up-to-date becomes a responsibility
+  of the authorizer. This is a **breaking change** for authorizer modules.
+<a name="1-10-x-tasks-pending-authoirization-deprecated"></a>
+* The field `pending_tasks` in `GetTasks` master API call has been deprecated.
+  From now on, this field will be empty. Moreover, the notion of
+  *tasks pending authorization* no longer exists
+  (see [MESOS-10056](
+<a name="1-10-x-allocator-module-changes"></a>
+* Allocator interface has been changed to supply allocator with information on
+  resources actually consumed by frameworks. A method
+  `transitionOfferedToAllocated(...)` has been added and the signature of
+  `recoverResources(...)` has been extended. Note that allocators must implement
+  these new/extended method signatures, but are free to ignore resource
+  consumption data provided by master.
