Known regressions introduced in this release

Features added since Pacemaker-2.1.5
- CIB: deprecate "moon" in date_spec elements in rules
- CIB: deprecate support for Nagios resources
- 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
- pacemakerd: -S should wait for cluster to shut down before returning (regression introduced in 2.1.1)
- 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)
- pacemaker-attrd: Preserve a Pacemaker Remote node's transient attributes if its connection to the cluster is lost but reconnects
- 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: avoid double-incrementing failcount for simulated failures
- controller: avoid reprobing remote nodes when target is a cluster node
- controller: delay join finalization if a transition is in progress
- controller: initial fencing timeout includes any priority-fencing-delay
- 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
- fencer: apply priority-fencing-delay only to first device tried
- fencer: total and per-device fencing timeouts include any priority-fencing-delay and pcmk_delay_base
- 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: honor as many mandatory colocations as possible before considering any optional ones
- scheduler: ensure earlier group member starts occur after later member stops
- 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
