The OpenVPN community project team is proud to release OpenVPN 2.4.8. It
can be downloaded from here:


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
* Latest OpenVPN-GUI
* Considerable performance boost due to new compiler optimization flags

A summary of all included changes is available here:


A full list of changes is available here:


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

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.

Please note that OpenVPN 2.4 installers will not work on Windows XP.
