+
+       * Released as 3.9.0.
+
+       * We decode Compute Express Link (CXL) capabilities.
+
+       * The tree mode of lspci is now compatible with filtering options.
+
+       * When setpci is used with a named register, it checks whether
+         the register is present in the particular header type.
+
+       * Linux: The intel-conf[12] back-ends prefer to use ioperm() instead
+         of iopl() to gain access to I/O ports.
+
+       * Windows: We have two new back-ends thanks to Pali Rohár.
+         One uses the NT SysDbg interface, the other uses kldbgdrv.sys
+         (which is a part of the Microsoft WinDbg tool).
+
+       * Windows: We support building libpci as a DLL. Also, Windows
+         binaries now include meta-data with version.
+
+       * Hurd: The Hurd back-end works again.
+
+       * mmio-conf1(-ext): Added a new back-end implementing the intel-conf1
+         interface over MMIO. This is useful on some ARM machines, but it
+         requires manual configuration of the MMIO addresses.
+
+       * As usually, updated pci.ids to the current snapshot of the database.
+

+
+       * Released as 3.8.0.
+
+       * Filters can now match devices based on partially specified
+         class code and also on the programming interface.
+
+       * Reporting of link speeds, power limits, and virtual function tags
+         has been updated to the current PCIe specification.
+
+       * We decode the Data Object Exchange capability.
+
+       * Bus mapping mode works in non-zero domains.
+
+       * pci_fill_info() can fetch more fields: bridge bases, programming
+         interface, revision, subsystem vendor and device ID, OS driver,
+         and also parent bridge. Internally, the implementation was rewritten,
+         significantly reducing the number of corner cases to be handled.
+
+       * The Windows port was revived and greatly improved by Pali Rohár.
+         It requires less magic to compile. More importantly, it runs on both
+         old and recent Windows systems (see README.Windows for details).
+
+       * Added a new Windows back-end using the cfgmgr32 interface.
+         It does not provide direct access to the configuration space,
+         but basic information about the device is reported via pci_fill_info().
+         For back-ends of this type, we now provide an emulated read-only
+         config space.
+
+       * If the configuration space is not readable for some reason
+         (e.g., the cfgmgr32 back-end, but also badly implemented sleep mode
+         of some devices), lspci prints only information provided by the OS.
+
+       * The Hurd back-end was greatly improved thanks to Joan Lledó.
+
+       * Various minor bug fixes and improvements.
+
+       * We officially require a working C99 compiler. Sorry, MSVC.
+
+       * As usually, updated pci.ids to the current snapshot of the database.

        * Released as 3.7.0.
