+
+ * Will be released as 3.11.0.
+
+ * update-pciids now supports XZ compression. If libpci is configured
+ with support for compression, all downloaded files are recompressed
+ as gzip. Otherwise they are stored as plain text.
+
+ * update-pciids now sends itself as the User-Agent.
+
+ * Added a pcilmr utility for PCIe lane margining. Thanks to Nikita
+ Proshkin for contributing it.
+
+ * Re-factored access to i386 ports on all relevant platforms.
+
+ * Added i386 port access on OpenBSD.
+
+ * Linux systems without pread/pwrite are no longer supported
+ as they are hopefully long gone. This helps avoid the tricky check
+ for presence of pread which was found to fail on musl libc.
+
+ * Improved decoding of PCIe control and status registers.
+
+ * Decoding of CXL capabilities now supports up to CXL 3.0.
+
+ * lspci now displays interrupt message numbers consistently across
+ different capabilities.
+
+ * Cache of IDs resolved via DNS, which was located in ~/.pci-ids
+ by default, is now stored according to the XDG base directory
+ specification in $XDG_CACHE_HOME/pci-ids.
+
+ * All source files now have SPDX license identifiers.
+
+ * Internal: The "aux" fields of structs pci_access and pci_dev
+ reserved for use by back-ends were renamed to backend_data to better
+ reflect their meaning.
+
+ * As usually, various minor bug fixes and updated pci.ids.
+
+2023-05-01 Martin Mares <mj@ucw.cz>
+
+ * Released as 3.10.0.
+
+ * Fixed bug in definition of versioned symbol aliases
+ in shared libpci, which made compiling with link-time
+ optimization fail.
+
+ * Filters now accept "0x..." syntax for backward compatibility.
+
+ * Windows: The cfgmgr32 back-end which provides the list of devices
+ can be combined with another back-end which provides access
+ to configuration space.
+
+ * ECAM (Enhanced Configuration Access Mechanism), which is defined
+ by the PCIe standard, is now supported. It requires root privileges,
+ access to physical memory, and also manual configuration on some
+ systems.
+
+ * lspci: Tree view now works on multi-domain systems. It now respects
+ filters properly.
+
+ * Last but not least, pci.ids were updated to the current snapshot
+ of the database. This includes overall cleanup of entries with
+ non-ASCII characters in their names -- such characters are allowed,
+ but only if they convey interesting information (e.g., umlauts
+ in German company names, but not the "registered trade mark" sign).
+
+2022-11-20 Martin Mares <mj@ucw.cz>
+
+ * 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.
+
+2022-04-18 Martin Mares <mj@ucw.cz>
+
+ * 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.
+
+2020-05-31 Martin Mares <mj@ucw.cz>
+
+ * Released as 3.7.0.
+
+ * Added or improved the following capabilities: Designated Vendor-Specific,
+ Compute eXpress Link, Resizable BARs, VF Resizable BARs, Link
+ Capabilities 2, Link Status 2.
+
+ * On Linux, lspci can show IOMMU groups.
+
+ * setpci can be asked to skip bus scan and operate on a device
+ completely specified by its domain/bus/dev/func address. This
+ involved major internal cleanup.
+
+ * The above feature of setpci uses the pci_get_dev() function,
+ which obtains a struct pci_dev without doing a bus scan. This was
+ always possible, but apparently little used, because back-ends
+ frequently choked when operating on such devices. Fixed a lot
+ of minor bugs related to this.
+
+ * Also, back-ends which do not support domains now correctly fail when
+ trying to access devices outside domain 0.
+
+ * Semantics of pci_fill_info() and pci_dev->known_fields was underspecified,
+ which lead to inconsistencies between back-ends. Improved documentation
+ to give a more precise definition and updated all back-ends to conform
+ to it. Most importantly, pci_dev->known_fields shows all fields requested
+ over the lifetime of the pci_dev, but never those which are not supported
+ by the back-end.
+
+ * As usually, updated pci.ids to the current snapshot of the database.
+
+2020-01-25 Martin Mares <mj@ucw.cz>
+
+ * Released as 3.6.4.
+
+ * A new back-end for the GNU Hurd was contributed by Joan Lledó.
+
+ * When printing VPD item identifiers, non-ASCII characters are escaped.
+
+2020-01-22 Martin Mares <mj@ucw.cz>
+
+ * Released as 3.6.3.
+
+ * `lspci -t' (tree mode) can be combined with `-s' to show a sub-tree.
+ We also fixed potential buffer overflows in the tree dumper.
+
+ * Cleaned messy code for dumping of I/O, memory, and ROM regions.
+ This helped fixing a bug, which caused some 64-bit regions to be
+ reported as virtual. All flags are now printed after the address
+ (previously, "[virtual]" and "[enhanced]" were before it for no good
+ reason).
+
+ * Added pci_find_cap_nr() to the library, which handles capabilities
+ which occur multiple times in a single device.
+
+ * Minor improvements in printing of PCIe capabilities.
+
+ * We now decode the Multicast and Secondary PCI Express extended
+ capabilities.
+
+ * The list of capability names available to setpci was updated.
+
+ * Minor bugs were fixed in FreeBSD and Solaris ports.
+
+ * We now prefer HTTPS URLs in all documentation
+
+ * The pci.ids file has a man page.
+
+ * As usually, updated pci.ids to the current snapshot of the database.
+
+2018-08-12 Martin Mares <mj@ucw.cz>
+
+ * Released as 3.6.2.
+
+ * Added "-P" and "-PP" switches to lspci, which display the path
+ through bridges to each device.
+
+ * Fixed a couple of bugs in computation of bus topology. It was
+ previously used only for the tree display, but we re-use it for
+ computing the paths.
+
+ * As usually, updated pci.ids to the current snapshot of the database.
+
+2018-07-12 Martin Mares <mj@ucw.cz>
+
+ * Released as 3.6.1.
+
+ * Fixed compilation issues on Linux systems with MUSL libc.
+
+2018-06-30 Martin Mares <mj@ucw.cz>
+
+ * Released as 3.6.0.
+
+ * BARs reported by the OS, but not set on the device itself are
+ reliably marked with "[virtual]".
+
+ * Library: Introduced a generic mechanism of string properties. This
+ avoids lots of special cases and makes ABI compatibility easier.
+
+ * On Linux systems with OpenFirmware, report corresponding device tree nodes
+ as device properties.
+
+ * VPD decoder knows several non-standard extensions.
+
+ * When PCIe link speed is less than the maximum supported by the
+ device, it is explicitly marked as "downgraded".
+
+ * Several new capabilities are not decoded yet, but at least their
+ names are printed.
+
+ * The Null capability is easily decoded.
+
+ * Formatting of several capabilities was cleaned up.
+
+ * The VGA16 bit in the bridge control register is now supported.
+
+ * Added a port to SylixOS. Thanks to YuJian Gong for contribution.
+
+ * Added a port to DOS/DJGPP. Thanks to Rudolf Marek for contribution.
+
+ * The order in which back-ends are probed was decoupled from the
+ internal back-end IDs. This helps, because new back-ends must have
+ their ID allocated at the end to keep the ABI, but they might need
+ to be probed earlier.
+
+ * The fbsd-device back-end should work again.
+
+ * Fixed a couple of bugs. Most notably, DeviceName was not printed.
+
+ * As usually, updated pci.ids to the current snapshot of the database.

layout of htype2, so I'm a bit unsure about it wrt capabilities
