+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.
+
+2017-11-17 Martin Mares <mj@ucw.cz>
+
+ * Released as 3.5.6.
+
+ * Improvements of the FreeBSD back-end: read-only access for non-root,
+ support DragonFly BSD, support extended config space.
+
+ * MN VPD keyword is decoded correctly.
+
+ * As usually, updated pci.ids to the current snapshot of the database.
+
+2017-07-05 Martin Mares <mj@ucw.cz>
+
+ * Released as 3.5.5.
+
+ * Better decoding of AER capability.
+
+ * "Slot Implemented" flag is decoded for PCI/PCI-X to PCIe bridges.
+
+ * Minor fixes of decoding other capabilities.
+
+ * As usually, updated pci.ids to the current snapshot of the database.
+
+2017-02-25 Martin Mares <mj@ucw.cz>
+
+ * Released as 3.5.4.
+
+ * Previous version broke compilation on systems, for which lib/types.h
+ did not provide a 64-bit integer type. It is provided everywhere now.
+
+2017-02-15 Martin Mares <mj@ucw.cz>
+
+ * Released as 3.5.3.
+
+ * When lspci looks for Linux kernel modules, it uses the default
+ path to module directory provided by libkmod. Previously,
+ it tried to construct the path explicitly, which need not
+ work on all systems.
+
+ * Improved formatting of memory and I/O ranges behind a bridge.
+
+ * PCIe link capabilities now display GEN4 speed (16GT/s).
+
+ * PCIe device capabilities now show bits related to atomic operations.
+ Thanks to Satanand Burla for a patch.
+
+ * As usually, updated pci.ids to the current snapshot of the database.
+
+2016-10-03 Martin Mares <mj@ucw.cz>
+
+ * Released as 3.5.2.
+
+ * The L1 power management capability is now decoded more
+ thoroughly. Thanks to Rajat Jain for the patch.
+
+ * The table of configuration registers used by setpci
+ had a bug in the definition of SUBSYSTEM_VENDOR_ID.
+
+2016-05-22 Martin Mares <mj@ucw.cz>
+
+ * Released as 3.5.1.
+
+ * Fixed symbol versioning of pci_init().
+
+2016-05-19 Martin Mares <mj@ucw.cz>
+
+ * Released as 3.5.0.
+
+ * New capabilities decoded: Downstream Port Containment,
+ Precision Time Measurement. Thanks to Keith Busch and
+ Jonathan Yong.
+
+ * Domain numbers extended to 31 bits. This will be used by the
+ Linux kernel on some machines in near future.
+
+ * Enhanced allocation regions are now decoded on Linux.
+
+ * The NetBSD back-end supports PCIe extended configuration space.
+
+ * Updated pci.ids to the current snapshot of the database.
+
+2016-01-03 Martin Mares <mj@ucw.cz>
+
+ * Released as 3.4.1.
+
+ * New capabilities decoded: Process Address Space, Page Request
+ Interface, Enhanced Allocation. Thanks to David Daney and
+ David Woodhouse.
+
+ * DevCap SlotPowerLimit is now decoded for all components with
+ upstream ports.
+
+ * Database mirror at SourceForge moved to GitHub.
+
+ * Updated pci.ids to the current snapshot of the database.
+
+2015-09-14 Martin Mares <mj@ucw.cz>
+
+ * Released as 3.4.0.
+
+ * On Linux, we report NUMA nodes of devices.
+
+ * The sysfs back-end does not die on read errors
+ of optional attributes. Instead, a warning is produced.
+
+ * Fixed several minor bugs.
+
+ * Updated pci.ids to the current snapshot of the database.
+
+2015-04-09 Martin Mares <mj@ucw.cz>
+
+ * Released as 3.3.1.
+
+ * Removed hacks for backward compatibility with Linux libc5,
+ which were breaking newer non-glibc Linux systems. Thanks
+ to Felix Janda.
+
+ * Display VirtIO vendor-specific capability. Patch by Gerd
+ Hoffmann.
+
+ * Fixed memory leak in name cache.
+
+ * Updated pci.ids to the current snapshot of the database.
+
+2014-11-10 Martin Mares <mj@ucw.cz>
+
+ * Released as 3.3.0.
+ (celebrating a one-year anniversary of the previous version :))
+
+ * Device names exported by BIOS are displayed on Linux.
+
+ * On Linux systems, HWDB is used to look up device names
+ when our ID database gives no match. (More precisely,
+ HWDB is consulted after local pci.ids, but before using
+ network to query online pci.ids.) Thanks to Tom Gundersen
+ for the initial patch.
+
+ * Added experimental back-end for OS X / Darwin. Thanks to
+ Richard Yao for providing it.
+
+ * Filters now support matching by device class. Original
+ patch by Matthew Wilcox, wrappers for ABI compatibility
+ by me.
+
+ * Interrupt Pin and Interrupt Line registers are displayed
+ for bridge devices, too.
+
+ * Several portability bugs have been fixed.
+
