Features added since Pacemaker-2.0.5

• support for OCF Resource Agent API 1.1 standard
  • allow Promoted and Unpromoted role names in CIB (in addition to Master and Slave, which are deprecated), and use new role names in output, logs, and constraints created by crm_resource --ban
  • advertise 1.1 support to agents, and provide notify_promoted_* and notify_unpromoted_* environment variables to agents with notify actions
  • support "reloadable" parameter attribute and "reload-agent" action in agents that advertise 1.1 support
  • support 1.1 standard in ocf:pacemaker:Dummy, ocf:pacemaker:remote, and ocf:pacemaker:Stateful resource agents
  • add "promoted-only" (in addition to "master-only", which is deprecated) in crm_mon XML output for bans
• support for noncritical resources
  • colocation constraints accept an "influence" attribute that determines whether dependent influences main resource's location (the default of "true" preserves the previous behavior, while "false" makes the dependent stop if it reaches its migration-threshold in failures rather than cause both resources to move to another node)
  • resources accept a "critical" meta-attribute that serves as default for all colocation constraints involving the resource as the dependent, as well as groups involving the resource
• detail log uses millisecond-resolution timestamps when Pacemaker is built with libqb 2.0 or later
• CIB: deprecate the remove-after-stop cluster property, can_fail action meta-attribute, and support for Upstart-based resources
• controller: the PCMK_panic_action environment variable may be set to sync-crash or sync-reboot to attempt to synchronize local disks before crashing or rebooting, which can be helpful to record cached log messages but runs the risk of the sync hanging and leaving the host running after a critical error
• tools: CIB_file="-" can be used to get the CIB from standard input

Build process changes since Pacemaker-2.0.5

• Pacemaker requires newer versions of certain dependencies, including Python 3.2 or later (support for Python 2 has been dropped), glib 2.32.0 or later, libqb 0.17.0 or later, GnuTLS 2.12.0 or later (to enable Pacemaker Remote support), rpm 4.11.0 (if building RPMs), and a C library that provides setenv() and unsetenv()
• configure: --enable-legacy-links (which is deprecated) defaults to "no", meaning that symbolic links will not be created for the Pacemaker 1 daemon names
• configure: --enable-compat-2.0 prevents certain output changes (most significantly role names) to maintain compatibility with older tools, scripts, and resource agents that rely on previous output
• configure: --with-resource-stickiness-default sets a resource-stickiness default in newly created CIBs
• configure: --with-concurrent-fencing-default specifies default for concurrent-fencing cluster property
• configure: --with-sbd-sync-default specifies default for syncing start-up with sbd
• configure: --with-ocfrapath specifies resource agent directories to search
• configure: --with-ocfrainstalldir specifies where to install ocf:pacemaker agents
• configure: --with-gnutls="no" explicitly disables support for Pacemaker Remote and the remote-tls-port cluster property
• configure: --with-acl has been removed (support for ACLs is always built)
• configure: deprecated --with-pkgname, --with-pkg-name, --with-brand, --enable-ansi, and --enable-no-stack options have been removed
• environment variables file (typically /etc/sysconfig/pacemaker or /etc/default/pacemaker) will be installed when "make install" is run
• documentation has dependency on python3-sphinx instead of publican, and is generated beneath doc/sphinx

Fixes since Pacemaker-2.0.5

• controller: always refresh agent meta-data after start, in case agent was updated (regression introduced in 1.1.18)
• tools: avoid crash when running crm_mon in daemonized mode with CGI output (regression introduced in 2.0.3)
• tools: correctly treat unspecified node as all nodes instead of local node when attrd_updater --query or crm_resource --cleanup is run on a Pacemaker Remote node (regressions introduced in 1.1.14 and 1.1.17)
• pacemaker-attrd: avoid race condition where transient attributes for a leaving node could be reinstated when the node rejoins, potentially causing a node that was just rebooted to exit the cluster immediately after rejoining
• controller,scheduler: fix year 2038 issues affecting shutdowns, remote node fencing, last-rc-change, and ticket last-granted dates
• controller: retry scheduler connection after failure, to avoid cluster stopping on a node without stopping resources (clbz#5445)
• fencing: avoid pending fencing entry getting "stuck" in history if originating node was unreachable when result was received
• fencing: retry getting agent meta-data if initial attempt fails
• fencing: detect when devices have been removed from configuration
• scheduler: constrain clone-min, clone-max, clone-node-max, promoted-max, and promoted-node-max options to non-negative values
• scheduler: constrain resource priorities and node-health-base to score range
• scheduler: treat invalid duration fields in time-based rules as 0, not -1
• scheduler: node attribute rule expressions with a value-source of "param" or "meta" work when rsc or rsc-pattern with an inverted match is given, as well as when rsc-pattern with a regular match is given
• scheduler: node attribute rule expressions with a value-source of "param" work with a resource parameter that itself is determined by a node attribute rule expression
• scheduler: avoid remote connection shutdown hanging when connection history for node hosting connection is not last in CIB status
• scheduler: route monitor cancellations behind moving remote connections correctly
• libcrmcommon: avoid potential integer overflow when adding seconds to times
• tools: cibsecret syncs to remote nodes and guest nodes as well as cluster nodes
• tools: show other available cluster information in crm_mon even if fence history is not available
• tools: retry failed fencer and CIB connections in crm_mon
• tools: crm_mon reports if Pacemaker is waiting for sbd at start-up
• tools: respect rules when showing node attributes in crm_mon
• tools: improve messages when crm_mon is run on disconnected remote node
• tools: constrain node IDs to non-negative values for crm_node -N
• tools: crm_node -l on restarted node works even when Corosync 2 is used without node names specified in Corosync configuration
• tools: fix issues in calculation of non-sensitive resource parameter digests that made crm_simulate wrongly think configuration changed
