+
+File based Metric Map
+---------------------
+Allow watcher to load a yaml file which contains a map of internal metrics
+names (as expected by watcher) to real metrics names in use in the
+datasources.
+
+Global datasource preference
+----------------------------
+Some clouds might only have a single datasource available setting the
+datasource preference for every individual strategy is error prone and
+time consuming. A global datasource preference prevents errors and
+simplifies configuring watcher.
+
+Add resource_name in action input parameter
+-------------------------------------------
+Currently watcher has only UUIDs for users to distinguish different actions
+which is not friendly. This BP will add a resource_name field in action
+input parameters which is more user friendly.
+
+Add Show Datamodel API
+----------------------
+Add Show Datamodel API to see the information of the instance in
+the specified scope.
+
+Add force field to Audit
+------------------------
+As now, Watcher doesn't allow to launch a new audit when there is actionplan
+ongoing. This is because if the new audit has the same data model as the
+ongoing actionplan, the new audit may create a wrong actionplan.
+But if there are different data model scope, we should allow the new audit
+to run. We want to give the choice to User, if User set force to True when
+launching audit, Watcher will execute the audit even other actionplan is
+ongoing.
+
+Support Placement API
+---------------------
+Placement provides a service for managing, selecting, and claiming available
+resources in a cloud. Many Watcher strategies need to select a target host
+for VM migrating. Watcher can improve the process by the help of placement.
