Npcap 1.84

Installer and debug symbols available from https://npcap.com/#download

  • Fixed a regression in #742 (previously fixed in Npcap 1.80). The fix changes
    to libpcap had been overwritten in our local branch, causing the same
    Application Verifier faults to recur.

  • Resolve an issue in the installer/uninstaller where x64-emulated processes on
    ARM64 (and possibly 32-bit processes on both x64 and ARM64) that were using
    Npcap were not correctly terminated, leading to failed installations.

  • New DriverQuery.exe diagnostic tool. This will be run as part of
    DiagReport
    on new installations, but can be run independently on older installations for
    better diagnosis of connection issues.

  • Added performance metrics for time spent processing packets. These can be
    queried with the DriverQuery diagnostic tool or via PacketGetInfo() using
    the NPF_GETINFO_STATS query ID.

  • Added additional checks to ensure data structures allocated when injecting
    packets are freed. No leaks were reported, but it is possible some packets
    could have been leaked when using the SendToRx feature.

  • An experimental feature, adaptive buffer sizing, can be enabled in Packet.dll
    by setting the PACKET_EXPERIMENTAL_OPTIMIZATION environment variable.
    See (#622).
