Npcap 0.9997 [2020-08-25]

    Fix an integer underflow in the amount of free buffer space
available leading to excessive memory consumption. Fixes #223.

    Significantly reduced per-packet memory overhead for packets in the
kernel capture buffer.

    Replaced object pool/slab allocator with Windows lookaside lists,
improving performance by avoiding spinlocks and allowing the system to
adjust memory consumption.
