    Red Hat Ansible Automation Platform provides an enterprise framework for building, deploying and managing
    IT automation at scale. IT Managers can provide top-down guidelines on how automation is applied to
    individual teams, while automation developers retain the freedom to write tasks that leverage existing
    knowledge without the overhead. Ansible Automation Platform makes it possible for users across an
    organization to share, vet, and manage automation content by means of a simple, powerful, and agentless
    language.

    Security Fix(es):
    * python3-django/python39-django: Potential denial of service vulnerability in
    django.utils.encoding.uri_to_iri() (CVE-2023-41164)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and
    other related information, refer to the CVE page(s) listed in the References section.

    Additional changes:
    * ansible-core has been updated to 2.15.4 (AAP-16010)
    * ansible-runner has been updated to 2.3.4 (AAP-15594)
    * automation-controller has been updated to 4.4.4 (AAP-15594)
    * python3-django/python39-django has been updated to 3.2.21 (AAP-15704)

    Updates and fixes for automation controller:
    * Fixed job error handling so that we correctly report error text from ansible-runner or receptor in cases
    we previously showed Job terminated due to error (AAP-12917)
    * The constructed inventory edit form no longer hangs indefinitely in the loading state for users with
    edit permissions (AAP-15099)
    * Added views for a monthly summary of host metrics (AAP-15677)
    * Added host metrics to exported analytics data (AAP-15677)
    * Introduced a periodic task and management command for cleaning up old host metrics (AAP-15677)
    * Fixed bug where rapidly clicking on launch button in preview step would launch multiple jobs (AAP-15689)
    * Fixed incorrect capacity for remote execution nodes when resource limits are set in OpenShift
    (AAP-15736)
