• Increase strictness in checking for and restoring adapter parameters modified during capture:
  hardware packet filter and lookahead will only be modified if the original value can be
  determined. This fixes issues with connectivity on certain adapter types (WWAN and some WiFi
  adapters) after a capture is closed.

• Modify NDIS binding parameters so that Npcap will bind both above and below a NIC teaming or
  network bridge IM driver. This may improve capture options in related situations, like #115.

• Updated build configurations to enable DEP and ASLR for npcap.sys, which were missing from the
  original configs inherited from WinPcap. Additionally, enabled Control Flow Guard for Packet.dll
  and all helper EXEs.

• Fix a BSoD issue on Windows 8.1 due to registering a service without a name. Fixes #565.

• Fix an issue with admin-only mode where high-integrity processes (UAC not enforced) could not open
  or list adapters. Fixes #606.

• Restored an undocumented data member of the struct ADAPTER that is not used internally. Directly
  accessing members of the ADAPTER struct from Packet32.h is highly discouraged, since the
  API in Packet32.h is not intended for use apart from libpcap. Closes #609.

• Extensive refactoring of driver code for performance and maintainability.
