+- Features added since Pacemaker-2.1.5
+  + CIB: utilization attributes may be set as transient
+  + CIB: alerts and alert recipients support an "enabled" meta-attribute
+  + All daemons support --output-as/--output-to options including
+    XML output with interactive options
+  + tools: attrd_updater supports --wait parameter that can be set to
+           "no" (return immediately after submitting request, which is
+           the default and previous behavior), "local" (return after the
+           new value has taken effect on the local node), or "cluster" (return
+           after new value has taken effect on all nodes)
+  + tools: attrd_updater supports -z/--utilization to modify utilization
+           attributes
+  + tools: attrd_updater supports --pattern to affect all attributes
+           matching a given pattern
+  + tools: crm_attribute supports --pattern with permanent node attributes
+           (in addition to previous support for transient attributes)
+  + tools: crm_mon displays resource descriptions if --show-description or
+           --show-detail is given
+  + tools: crm_mon shows maintenance mode when enabled per-resource
+  + tools: crm_mon --interval can be used to update XML and text output
+           (in addition to previous support for HTML)
+  + tools: crm_mon fencing history includes microseconds in timestamps
+  + tools: crm_mon shows which node it was run on
+  + tools: crm_mon shows whether Pacemaker or Pacemaker Remote is running or
+           shutting down
+  + tools: deprecate crm_mon --simple-status
+  + tools: crm_resource --element option can be used with --get-parameter,
+           --set-parameter, and --delete-parameter to modify resource
+           properties such as class, provider, type, and description
+  + tools: crm_resource --list shows resource descriptions better
+           (including when --output-as=xml is used)
+  + tools: crm_shadow supports standard --output-as/--output-to arguments
+
+- Fixes since Pacemaker-2.1.5
+  + Pacemaker Remote: remote nodes wait for all-clear from cluster before
+                      shutting down (regression introduced in 2.1.5)
+  + tools: attrd_updater --query without --node shows attributes from all
+           nodes instead of local node (regression introduced in 2.1.5)
+  + CIB manager: successful CIB schema upgrade always forces a write
+  + controller: avoid election storm when joining node has CIB newer than DC
+                can accept
+  + controller: avoid election storm due to incompatible CIB
+  + controller: avoid use-after-free when disconnecting proxy IPCs during shutdown
+  + controller: delay join finalization if a transition is in progress
+  + controller: avoid double-incrementing failcount for simulated failures
+  + controller: avoid reprobing remote nodes when target is a cluster node
+  + controller: shutdown gracefully if scheduler connection is interrupted
+                during shutdown
+  + fencer: avoid crash during shutdown when action is pending
+  + fencer: calculate fencing timeout correctly when watchdog is used with
+            topology
+  + scheduler: fix a number of corner cases with colocations, including
+               preventing a resource from starting if it has a mandatory
+               colocation with a group whose start is blocked, preventing
+               optional anti-colocation from overriding infinite stickiness,
+               and correctly considering a group's colocation dependents
+               when the group is itself colocated with a clone
+  + scheduler: handle orderings with bundles more correctly
+  + scheduler: ensure expired results never affect resource state
+  + scheduler: handle cleaned migrate_from history correctly
+  + scheduler: prevent pending monitor of one clone instance from causing
+               unexpected stop of other instances
+  + scheduler: prevent inactive clone instances from starting if probe is
+               unrunnable on any node
+  + agents: SysInfo calculates cpu_load correctly
+  + tools: cibadmin --scope accepts status
+  + tools: crm_attribute -p "" works same as -p when called from resource agent
+  + tools: crm_attribute recognizes "-INFINITY" as value instead of options
+  + tools: crm_mon avoids displaying recurring monitors as pending if first
+           attempt fails
+  + tools: crm_mon --daemonize shows disconnected message when CIB connection
+           is lost instead of continuing to display last known state
+  + tools: crm_mon avoids crash when built without curses library support
+  + tools: crm_mon supports --output-as=none correctly
+  + tools: crm_resource --ban or --move works with single-replica bundles
+  + tools: crm_shadow --commit now works with CIB_file
+  + tools: crm_simulate failure injection avoids crash if node name is unknown
+
