Installer and debug symbols available from https://npcap.org/ . Note the version number structure change.

• Fix a bug in the BPF packet filter engine that caused capture filters with
  byte offsets to reject packets due to fragmentation within NET_BUFFER
  structures. See #1406 and
  #1438.

• Fix a bug that caused several network device drivers to crash when using the
  pcap_sendqueue_transmit function, due to queued network packets being
  allocated from paged memory that paged out before the drivers accessed it.
  See #1398.

• Fix a crash (SYSTEM_EXCEPTION_NOT_HANDLED_M) in WSKCloseSocket due to
  double-free, reported via Microsoft crash telemetry.

• Fix a BSOD inherited from WinPcap triggered when PacketGetStats is called
  with low system resources. See #1517.

• Properly quote the path to the CheckStatus.bat script in the
  npcapwatchdog scheduled task. See #1513.

• Fix errors when installing in WinPcap API-compatible mode over WinPcap when
  Npcap install directory does not already exist. See
  #1456.
