OpenVPN v2.4.0 was audited for security vulnerabilities independently by
Quarkslabs (funded by OSTIF) and Cryptography Engineering (funded by
Private Internet Access) between December 2016 and April 2017. The
primary findings were two remote denial-of-service vulnerabilities.
Fixes to them have been backported to v2.3.15. Our official security
announcement is here:

Compared to OpenVPN 2.3 this is a major update with a large number of
new features, improvements and fixes. Some of the major features are
AEAD (GCM) cipher and Elliptic Curve DH key exchange support, improved
IPv4/IPv6 dual stack support and more seamless connection migration when
client's IP address changes (Peer-ID). Also, the new --tls-crypt feature
can be used to increase users' connection privacy.

OpenVPN GUI bundled with the Windows installer has a large number of new
features compared to the one bundled with OpenVPN 2.3. One of major
features is the ability to run OpenVPN GUI without administrator privileges.
