Features added since Pacemaker-1.1.16

• New "bundle" resource type for Docker container use cases (experimental)
• New "PCMK_node_start_state" environment variable to start node in standby
• New "value-source" rule expression attribute in location constraints to
  compare a node attribute against a resource parameter
• New "stonith-max-attempts" cluster option to specify how many times
  fencing can fail for a target before the cluster will no longer
  immediately re-attempt it (previously hard-coded at 10)
• New "cluster-ipc-limit" cluster option to avoid IPC client eviction in
  large clusters
• Failures are now tracked per operation type, as well as per node and
  resource (the "fail-count" and "last-failure" node attribute names now end
  in "#OPERATION_INTERVAL")
• attrd: Pacemaker Remote node attributes and regular expressions are now
  supported on legacy cluster stacks (heartbeat, CMAN, and corosync plugin)
• tools: New "crm_resource --validate" option
• tools: New "stonith_admin --list-targets" option
• tools: New "crm_attribute --pattern" option to match a regular expression
• tools: "crm_resource --cleanup" and "crm_failcount" can now take
  --operation and --interval options to operate on a single operation type

Changes since Pacemaker-1.1.16

• Fix multiple memory issues (leaks, use-after-free) in libraries
• pengine: unmanaging a guest node resource puts guest in maintenance mode
• cib: broadcasts of cib changes should always pass ACL checks
• crmd,libcrmcommon: update throttling when CPUs are hot-plugged
• crmd: abort transition whenever we lose quorum
• crmd: avoid attribute write-out on join when atomic attrd is used
• crmd: check for too many stonith failures only when aborting for that reason
• crmd: correctly clear failure counts only for a specified node
• crmd: don't fence old DC if it's shutting down as soon-to-be DC joins
• crmd: forget stonith failures when forgetting node
• crmd: all nodes should track stonith failure counts in case they become DC
• crmd: update cache status for guest node whose host is fenced
• dbus: prevent lrmd from hanging on dbus calls
• fencing: detect newly added constraints for stonith devices
• pengine: order remote actions after connection recovery
  (regression introduced in 1.1.15)
• pengine: quicker recovery from failed demote
• libcib: determine remote nodes correctly from node status entries
• libcrmcommon: avoid evicting IPC client if messages spike briefly
• libcrmcommon: better XML comment handling prevents infinite election loop
• libcrmcommon: set month correctly in date/time string sent to alert agents
• libfencing,fencing: intelligently remap "action" wrongly specified in config
• libservices: ensure completed ops aren't on blocked ops list
• libservices: properly detect and cancel in-flight systemd/upstart ops
• libservices: properly watch writable DBus handles
• libservices: systemd service that is reloading doesn't cause monitor failure
• pacemaker_remoted: allow graceful shutdown while unmanaged
• pengine,libpe_status: don't clear same fail-count twice
• pengine: consider guest node unclean if its host is unclean
• pengine: do not re-add a node's default score for each location constraint
• pengine: avoid restarting services when recovering remote connection
• pengine: better guest node recovery when host fails
• pengine: guest node fencing doesn't require stonith enabled
• pengine: allow probes of guest node connection resources
• pengine: properly handle allow-migrate explicitly set for remote connection
• pengine: fence failed remote nodes even if no resources can run on them
• tools: resource agents will now get the correct node name on
  Pacemaker Remote nodes when using crm_node and crm_attribute
• tools: avoid grep crashes in crm_report when looking for system logs
• tools: crm_resource -C now clears last-failure as well as fail-count
• tools: implement crm_failcount command-line options correctly
• tools: properly ignore version with crm_diff --no-version
