This release fixes the following bugs:

• Previously, node upgrade playbooks scoped all nodes instead of just the nodes that are filtered by the openshift_upgrade_nodes_label. As a result, nodes that were not intended to be upgraded had yum excluders disabled but not reenabled. With this release, the initialization of the variable for filtering nodes to upgrade is moved to earlier in the play, and preconfiguration is scoped to the filtered list of nodes. As a result, only the nodes that are intended for upgrade have yum excluders disabled. (BZ#1917013)

• Previously, node-based facts, such as l_kubelet_node_name, were set late in the upgrade cycle, causing the fact to be undefined when referenced. With this release, node-based fact initialization happens earlier in the upgrade cycle so that facts are set prior to being referenced. (BZ#1933090)

• Previously, a bug fix in Ansible 2.9.10 changed the behavior of delegate_to for plays using connection: local with hosts: localhost. This change caused tasks that are intended for remote hosts to be executed locally. With this release, connection: local is removed for the affected play, and tasks intended for remote hosts are executed on the remote host. (BZ#1934136)

Security Fix(es):

• golang-github-gorilla-websocket: integer overflow leads to denial of service (CVE-2020-27813)
