+       * 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.
