Fixes in

The following issues have been fixed in this release.

ID Number Description
825049-1 New code signing was not possible as the code signing certificate expired on December 11, 2019. With this release, the Edge Client includes a newer signing certificate.
838909-1 Previously, a malicious captive portal could prompt the user to provide his enterprise credentials and get access to the password hash. Now, with this release Edge client does not respond to such credential requests from captive portals.
857689-1 Previously, when using DTLS connection, the CPU usage could increase to 100%, impacting performance and throughput. Now, the issue is fixed, and the throughput speed is not impacted.
862641-1 Previously, in the Edge Client for Windows, the Stonewall service failed to disconnect traffic after the VPN is disconnected, and the user could access resources over the internet. Now, this issue is fixed, and traffic is blocked when the VPN is disconnected.
862709-1 On Windows Enterprise LTSC 2019, the Edge Client crashes after being connected for a period of time. Now, the issue is fixed, and the Edge Client no longer crashes.
863957-1 If the OPSWAT Endpoint Security (EPSEC) package is signed using a newer version of the certificate than the APM client, then each time the user logs in and an endpoint check is performed, OPSWAT components are downloaded and installed in a new folder. APM release fixes this issue and is compatible with the latest version of EPSEC. Refer EPSEC Release Notes and follow the guidelines to ensure APM client compatibility with EPSEC.
867413-1 Previously, in the Edge Client for macOS, sometimes the captive portal resolution feature did not work after reboot due to an issue in detecting the captive portal state. Now, the captive portal state is successfully detected, and this issue is fixed.
