What's New in Windows Packet Filter 3.6.2

Overview

This patch release (v3.6.2) delivers important maintenance updates to the Windows Packet Filter driver.
It is fully binary compatible with version 3.6.1, so no rebuilds of other components are required.
Only the Windows 7 and later drivers have been rebuilt for this release.

Fixes and Improvements

• Driver Signing Certificate Update:
  Fixed an issue where version 3.6.1 could fail to load due to an expired driver signing certificate.

• Bluetooth Stack Stability Fix:
