Version 5.1.1

- Fixed a bug causing MPPE key decryption to fail when MPPE was used with an EAP-message attribute. - Addresses an issue in prior v5.x.x releases where the running proxy stops responding to incoming RADIUS requests. - Added the Microsoft Visual C++ 2015-2019 Redistributable to the Windows Authentication proxy installer to ensure all required DLLs are present on the target system.
