- update to 2.4.0:
  + Add hwloc/cpukinds.h for reporting information about hybrid CPUs.
    - Use Linux cpufreq frequencies to rank cores by efficiency.
    - Use x86 CPUID hybrid leaf and future Linux kernels sysfs CPU type
      files to identify Intel Atom and Core cores.
    - Use the Windows native EfficiencyClass to separate kinds.
  + Properly handle Linux kernel 5.10+ exposing ACPI HMAT information
    with knowledge of Generic Initiators.
  + lstopo has new --cpukinds and --no-cpukinds options for showing
    CPU kinds or not in textual and graphical modes respectively.
  + hwloc-calc has a new --cpukind option for filtering PUs by kind.
  + hwloc-annotate has a new cpukind command for modifying CPU kinds.
  + Fix hwloc_bitmap_nr_ulongs(), thanks to Norbert Eicker.
  + Add a documentation section about
    "Topology Attributes: Distances, Memory Attributes and CPU Kinds".
  + Silence some spurious warnings in the OpenCL backend and when showing
    process binding with lstopo --ps.
  + Add hwloc/memattrs.h for exposing latency/bandwidth information
    between initiators (CPU sets for now) and target NUMA nodes,
    typically on heterogeneous platforms.
    - When available, bandwidths and latencies are read from the ACPI HMAT
      table exposed by Linux kernel 5.2+.
    - Attributes may also be customized to expose user-defined performance
      information.
  + Add hwloc_get_local_numanode_objs() for listing NUMA nodes that are
    local to some locality.
  + The new topology flag HWLOC_TOPOLOGY_FLAG_IMPORT_SUPPORT causes
    support arrays to be loaded from XML exported with hwloc 2.3+.
    - hwloc_topology_get_support() now returns an additional "misc"
      array with feature "imported_support" set when support was imported.

- hwloc_topology_get_support() now returns an additional "misc"
array with feature "imported_support" set when support was imported.
+ Add hwloc_topology_refresh() to refresh internal caches after modifying
the topology and before consulting the topology in a multithread context.
+ Add a ROCm SMI backend and a hwloc/rsmi.h helper file for getting
the locality of AMD GPUs, now exposed as "rsmi" OS devices.
Thanks to Mike Li.
+ Remove POWER device-tree-based topology on Linux,
(it was disabled by default since 2.1).
+ Command-line options for specifying flags now understand comma-separated
lists of flag names (substrings).
+ hwloc-info and hwloc-calc have new --local-memory --local-memory-flags
and --best-memattr options for reporting local memory nodes and filtering
by memory attributes.
+ hwloc-bind has a new --best-memattr option for filtering by memory attributes
among the memory binding set.
+ Tools that have a --restrict option may now receive a nodeset or
some custom flags for restricting the topology.
+ lstopo now has a --thickness option for changing line thickness in the
graphical output.
+ Fix lstopo drawing when autoresizing on Windows 10.
+ Pressing the F5 key in lstopo X11 and Windows graphical/interactive outputs
now refreshes the display according to the current topology and binding.
+ Add a tikz lstopo graphical backend to generate picture easily included into
LaTeX documents. Thanks to Clement Foyer.
+ The default installation path of the Bash completion file has changed to
${datadir}/bash-completion/completions/hwloc. Thanks to Tomasz Kłoczko.
