WinPcap, though still available for download (v4.1.3), has not seen an upgrade in many years and there are no road map/future plans to update the technology. While community support may persist, technical oversight by Riverbed staff, responses to questions posed by Riverbed resources, and bug reporting are no longer available.
Gordon Lyon, Nmap project founder, has created Npcap, a packet capture library for Windows, that includes WinPcap compatibility and may be a suitable replacement for WinPcap and WinPcap Pro. Information can be found at https://nmap.org/npcap/.
