Hello,
A new release candidate (1.11rc2) is available with the following
noticeable additional changes:
* Tools
+ lstopo
- Add --restrict-flags to configure the behavior of --restrict.
- Really export all verbose information to the given output file.
* Misc
+ Fix hwloc/cudart.h for machines with multiple PCI domains,
thanks to Imre Kerr for reporting the problem.
+ Fix some corner case in the building of levels on large NUMA machines
with non-uniform NUMA groups and I/Os.

> --------------
> * API
> + Socket objects are renamed into Package to align with the terminology
> used by processor vendors. The old HWLOC_OBJ_SOCKET type and "Socket"
> name are still supported for backward compatibility.
> + HWLOC_OBJ_NODE is replaced with HWLOC_OBJ_NUMANODE for clarification.
> HWLOC_OBJ_NODE is still supported for backward compatibility.
> "Node" and "NUMANode" strings are supported as in earlier releases.
> * Detection improvements
> + Add support for Intel Knights Landing Xeon Phi.
> Thanks to Grzegorz Andrejczuk and Lukasz Anaczkowski.
> + Add Vendor, Model, Revision, SerialNumber, Type and LinuxDeviceID
> info attributes to Block OS devices on Linux. Thanks to Vineet Pedaballe
> for the help.
> - Add --disable-libudev to avoid dependency on the libudev library.
> + Add "MemoryDevice" Misc objects with information about DIMMs, on Linux
> when privileged and when I/O is enabled.
> Thanks to Vineet Pedaballe for the help.
> + Add a PCISlot attribute to PCI devices on Linux when supported to
> identify the physical PCI slot where the board is plugged.
> + Add CPUStepping info attribute on x86 processors,
> thanks to Thomas Röhl for the suggestion.
> + Ignore the device-tree on non-Power architectures to avoid buggy
> detection on ARM. Thanks to Orion Poplawski for reporting the issue.
> + Work-around buggy Xeon E5v3 BIOS reporting invalid PCI-NUMA affinity
> for the PCI links on the second processor.
> + Add support for CUDA compute capability 5.x, thanks Benjamin Worpitz.
> + Many fixes to the x86 backend
> - Add L1i and fix L2/L3 type on old AMD processors without topoext
> support.
> - Fix Intel CPU family and model numbers when basic family isn't 6 or 15.
> - Fix package IDs on recent AMD processors.
> - Fix misc issues due to incomplete APIC IDs on x2APIC processors.
> - Avoid buggy discovery on old SGI Altix UVs with non-unique APIC IDs.
> + Gather total machine memory on NetBSD.
> * Tools
> + lstopo
> - Collapse identical PCI devices unless --no-collapse is given.
> This avoids gigantic outputs when a PCI device contains dozens of
> identical virtual functions.
> - The ASCII art output is now called "ascii", for instance in
> "lstopo -.ascii".
> The former "txt" extension is retained for backward compatibility.
> - Automatically scales graphical box width to the inner text in Cairo,
> ASCII and Windows outputs.
> - Add --rect to lstopo to force rectangular layout even for NUMA nodes.
> - Objects may have a Type info attribute to specific a better type name
> and display it in lstopo.
> + hwloc-annotate
> - May now operate on all types of objects, including I/O.
> - May now insert Misc objects in the topology.
> - Do not drop instruction caches and I/O devices from the output anymore.
> + Fix lstopo path in hwloc-gather-topology after install.
> * Misc
> + Fix PCI Bridge-specific depth attribute.
> + Fix hwloc_bitmap_intersect() for two infinite bitmaps.
> + Improve the performance of object insertion by cpuset for large
> topologies.
> + Prefix verbose XML import errors with the source name.
> + Improve pkg-config checks and error messages.
> + Fix excluding after a component with an argument in the HWLOC_COMPONENTS
> environment variable.
> + Fix the recommended way in documentation and examples to allocate memory
> on some node, it should use HWLOC_MEMBIND_BIND.
> Thanks to Nicolas Bouzat for reporting the issue.
> + Add a "Miscellaneous objects" section in the documentation.
> + Add a FAQ entry "What happens to my topology if I disable symmetric
> multithreading, hyper-threading, etc. ?" to the documentation.
