      * `pmdalinux`: The networking and `hugepages` kernel metrics were updated.
      * `pmdaamdgpu`: This new agent collects metrics from `libdrm` and `libdrm-amdgpu` libraries.
      * `pmdabpftrace`: The start of this agent with many or slow `bpftrace` scripts was fixed.
      * `pmdaproc`: This agent now collects new metrics from AMD GPUs from the Linux `fdinfo` interface.
      * `pmdahacluster`: Metrics were updated to support new Pacemaker versions.
      * `pmdastatsd`: A bug was fixed to avoid crashes under load.
      * `pcp-htop`: AMD GPU metrics support was added.
      * `pcp-htop`: Platform settings were fixed to enable screen tabs.

      Update PCP to latest stable upstream version.  This is expected to add a number of security improvements for two recent CVEs as well as numerous libpcp and pmcd hardening changes.  Several fixes from earlier zstreams targeting SAP HANA are also in this next release.

      Features include new kernel metrics and support for vLLM metrics for RHEL AI.
