• The Nmap Project's (Insecure.Com LLC) code signing certificate has been
  renewed, and no longer exists as a SHA-1 certificate. Windows Vista and
  Server 2008 may therefore not recognize the digital signatures on the
  filter driver so a warning may be presented upon install. Please note
  that Microsoft is ending support for these operating systems in January 2020.

• WinPcap API-compatible mode no longer installs a separate filter driver.
  Packet.DLL will translate NPF device names so that they are all serviced by
  the npcap.sys driver. The npf.sys driver has been removed. See
  #1812.

• Improve the speed of pcap_findalldevs by reducing the number of calls to
  GetAdaptersAddresses, removing a redundant function call, and improving
  buffer reallocation. Patch by Tomasz Moń
  (#20).

• Temporary DLLs unpacked during installation are now signed with our code
  signing certificate.

• Fixed a bug in the uninstaller preventing downgrades to prior versions of
  Npcap. On 64-bit Windows, the driver file npcap.sys was not properly
  removed, and Windows would not replace it with any older version. Fixes
  #1686.
