"- New upstream release

  - Actually reload the DFU device after upgrade has
    completed

  - Capture the dock SKU in report metadata

  - Correctly set the Logitech device protocol

  - Do not use shim for non-secure boot configurations

  - Ensure that the DeviceID is set for child devices

  - Fix an error when detaching MSP430

  - Fix the DeviceID set by GetDetails

  - Force the prometheus minor version from 0x02 to 0x01

  - Parse the CSR firmware as a DFU file

  - Prevent dell-dock updates to occur via synaptics-mst
    plugin

  - Rather than hardcoding thunderbolt to PCI slot numbers,
    use domain in GUID

  - Remove a dock device from the whitelist that is never
    going to be updated

  - Validate that gpgme_op_verify_result() returned at least
    one signature

  - Wait for the cxaudio device to reboot after writing
    firmware

  - Fixes CVE-2020-10759

description block directly from the Fedora update system website.
