Features added since Pacemaker-2.0.0

• fencing: SBD may now be used in a cluster that has guest nodes or bundles
• fencing: synchronize fencing history among all nodes
• fencing: stonith_admin now has option to clear fence history
• tools: crm_mon now supports showing fencing action failures and history
• tools: crm_resource --clear supports new --expired option
• Pacemaker Remote: option to restrict TLS Diffie-Hellman prime length

Changes since Pacemaker-2.0.0

• tools: restore stonith_admin ability to confirm unseen nodes are down
  (regression since 1.1.12)
• Pacemaker Remote: avoid unnecessary downtime when moving resource to
  Pacemaker Remote node that fails to come up (regression since 1.1.18)
• tools: crm_resource -C could fail to clean up all failures in one run
  (regression since 2.0.0)
• build: spec file now puts XML schemas in new pacemaker-schemas package
• build: spec file now provides virtual pcmk-cluster-manager package
• pacemaker-attrd: wait a short time before re-attempting failed writes
• pacemaker-attrd: ignore attribute delays when writing after node (re-)join
• CIB: inform originator of CIB upgrade failure
• controller: support resource agents that require node name even for meta-data
• controller: don't record pending clone notifications in CIB
• controller: DC detects completion of another node's shutdown more accurately
• controller: shut down DC if unable to update node attributes
• controller: handle corosync peer/join notifications for new node in any order
• executor: cancel recurring monitors if fence device registration is lost
• fencing: check for fence device update when resource defaults change
• fencing: fix possible pacemaker-fenced crash with stonith_admin misuse
• fencing: limit fencing history to 500 entries
• fencing: stonith_admin now complains if no action option is specified
• pacemakerd: Linux kernel.sysrq is no longer modified
• scheduler: avoid unnecessary recovery of cleaned guest nodes and bundles
• scheduler: ensure failures that cause fencing are not expired until fencing completes
• scheduler: start unique clone instances in numerical order
• scheduler: convert unique clones to anonymous clones if not supported by standard
• scheduler: associate pending tasks with correct clone instance
• scheduler: don't send clone notifications to a stopped remote node
• scheduler: ensure bundle clone notifications are directed to correct host
• scheduler: avoid improper monitor rescheduling or fail count clearing for bundles
• scheduler: honor asymmetric orderings even when restarting
• ACLs: assume unprivileged ACL user if can't get user info
• Pacemaker Remote: get Diffie-Hellman prime bit length from GnuTLS API
• libcrmservice: order systemd resources relative to pacemaker_remote
• libpe_status: add public API constructor/destructor for pe_working_set_t
• tools: make crm_mon CIB connection errors non-fatal if previously successful
• tools: improve crm_mon messages when generating HTML output
• tools: crm_mon cluster connection failure is now "critical" in nagios mode
• tools: crm_mon listing of standby nodes now shows if they still have active resources
• tools: crm_diff now ignores attribute ordering when comparing in CIB mode
• tools: improve crm_report detection of logs, CIB directory, running processes
• tools: crm_verify returns reliable exit codes
• tools: crm_simulate simulated resource history uses same name as live cluster would
