This is primarily a maintenance release with bugfixes and improvements. The Windows installers (I601) have several improvements compared to the previous release:
- New tap-windows6 driver (9.24.2) which fixes some suspend and resume issues
- Latest OpenVPN-GUI
- Considerable performance boost due to new compiler optimization flags
Please note that LibreSSL is not a supported crypto backend. We accept patches and we do test on OpenBSD 6.0 which comes with LibreSSL, but if newer versions of LibreSSL break API compatibility we do not take responsibility to fix that.
Also note that Windows installers have been built with NSIS version that has been patched against several NSIS installer code execution and privilege escalation problems. Based on our testing, though, older Windows versions such as Windows 7 might not benefit from these fixes. We thus strongly encourage you to always move NSIS installers to a non-user-writeable location before running them. Our long-term plan is to migrate to using MSI installers instead.
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. The new OpenVPN GUI features are documented here.
Please note that OpenVPN 2.4 installers will not work on Windows XP.
