The OpenVPN community project team is proud to release OpenVPN This is a small bugfix release. For details see Note License amendment all new commits fall under a modified license that explicitly permits linking with Apache2 libraries mbedTLS, OpenSSL - see COPYING for details. Existing code will fall under the new license as soon as all contributors have agreed to the change - work ongoing. Feature changes DCO support kernel-triggered key rotation avoid IV reuse after 232 packets. This is the userland side, accepting a message from kernel, and initiating a TLS renegotiation. As of release, only implemented in FreeBSD kernel. Windows MSI changes since Rebuilt included tap-windows driver with the correct version of the old Windows 7 driver, removing a warning about unsigned driver on Windows 7 installation.

Windows MSI changes since Several Windows-specific issues fixed ensure interactive service stays enabled after silent reinstall, see GH openvpn-build348, openvpn-build349 and openvpn-build351 repair querying install path info for on some Windows language versions, see GH openvpn-build352. MSIs are now built against OpenSSL Update included openvpn-gui to This update removes the ability to change the password of a private key from the GUI. This was a niche feature which caused a direct dependency of GUI on OpenSSL. Use directly if you need to edit a private key. Note Windows MSI was updated to I003 on April 26th. Changes in I003 The GPG subkey for creating the .asc files for the downloads has been updated. You might need to re-download or update the GPG key if verifying the signatures. Fix the encoding of some documentation/sample files included in the installer. See GH openvpn-build358 Update include tap-windows6 driver to Fixes a problem with sending small non-IP packets PPPoE over the VPN connection. See GH tap-windows6158 Note The new driver is only used on Windows 10 and newer. We can't rebuild drivers for Windows 7/8 since Microsoft doesn't support the signing mechanism anymore. We include the previous driver version to still allow installation on Windows 7/8. Update included openvpn-gui to Fixes a problem with passphrase prompt was sometimes not displayed. See GH openvpn-gui619 Adds "Password Reveal" feature which allows you to see passwords while entering them.

For details see Feature changes implement byte counter statistics for DCO Linux p2mp server and client implement byte counter statistics for DCO Windows client only -dns server address ... now permits up to 8 v4 or v6 addresses Important note for Linux DCO users New control packets flow for data channel offloading on Linux changes the way OpenVPN control packets are handled on Linux when DCO is active, fixing the lockups observed with under high client connect/disconnect activity. This is an INCOMPATIBLE change and therefore an ovpn-dco kernel module older than commit ID 726fdfe0fa21 will not work anymore and must be upgraded. The kernel module was renamed to " in order to highlight this change and ensure that users and userspace software could easily understand which version is loaded. Attempting to use the old ovpn-dco with will lead to disabling DCO at runtime.

For details see Feature changes Dynamic TLS Crypt When both peers are OpenVPN OpenVPN will dynamically create a tls-crypt key that is used for renegotiation. This ensure that only the previously authenticated peer can do trigger renegotiation and complete renegotiations. CryptoAPI Windows support issuer name as a selector. Certificate selection string can now specify a partial issuer name string as "-cryptoapicert ISSUER" where is matched as a substring of the issuer CA name in the certificate. Note configure now enables DCO build by default on FreeBSD and Linux. On Linux this brings in a new default dependency for libnl-genl for Linux distributions that are too old to have a suitable version of the library, use "configure -disable-dco" Windows MSI changes since Update included ovpn-dco-win driver to Windows 64-bit MSI installer GnuPG Signature Windows ARM64 MSI installer GnuPG Signature Windows 32-bit MSI installer GnuPG Signature Source archive file GnuPG Signature The OpenVPN community project team is proud to release OpenVPN This is a new stable release with some major new features.

New features and improvements in compared to Data Channel Offload DCO kernel acceleration support for Windows, Linux, and FreeBSD. OpenSSL 3 support. Improved handling of tunnel MTU, including support for pushable MTU. Outdated cryptographic algorithms disabled by default, but there are options to override if necessary. Reworked TLS handshake, making OpenVPN immune to replay-packet state exhaustion attacks. Added -peer-fingerprint mode for a more simplistic certificate setup and verification. Added Pre-Logon Access Provider support to OpenVPN GUI for Windows. Improved protocol negotiation, leading to faster connection setup.

One of the fixes is to password prompting on windows console when stderr redirection is in use - this breaks on Win11/ARM, and might also break on Win11/amd64. Windows executable and libraries are now built natively on Windows using MSVC, not cross-compiled on Linux as with earlier releases. Windows installers include updated OpenSSL and new OpenVPN GUI. The latter includes several improvements, the most important of which is the ability to import profiles from URLs where available. Installer version I602 fixes loading of pkcs11 files on Windows. Installer version I603 fixes a bug in the version number as seen by Windows was not Installer I604 fixes some small Windows issues.

If you really need to use an unsupported OpenVPN or even older release and need to stay on BF-CBC not recommended, the OpenVPN based client will need a config file change to re-enable BF-CBC.

In uncertain cases please contact our developers first, either using the openvpn-devel mailinglist or the developer IRC channel openvpn-devel at For generic help take a look at our official documentation, wiki, forums, openvpn-users mailing list and user IRC channel openvpn at Important you will need to use the correct installer for your operating system. The Windows 10 installer works on Windows 10 and Windows Server 2016/2019. The Windows 7 installer will work on Windows 7/8/ 2012r2. This is because of Microsoft's driver signing requirements are different for kernel-mode devices drivers, which in our case affects OpenVPN's tap driver tap-windows6.

You can use EasyRSA 2 or EasyRSA 3 for generating your own certificate authority. The former is bundled with Windows installers. The latter is a more modern alternative for UNIX-like operating systems. The Windows installers are bundled with OpenVPN-GUI - its source code is available on its project page and as tarballs on our alternative download server. This is primarily a maintenance release with bugfixes and improvements. One of the big things is enhanced TLS support. A summary of the changes is available in and 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 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. We are moving to MSI installers in OpenVPN but OpenVPN will remain NSIS-only. Compared to OpenVPN 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 One of major features is the ability to run OpenVPN GUI without administrator privileges.

The Windows 10 installer will not work on Windows 7/8/ 2012r2. This is because Microsoft's driver signing requirements and tap-windows6. For the same reason you need to use an older installer with Windows Server 2016. This older installer has a local privilege escalation vulnerability issue which we cannot resolve for Windows Server 2016 until tap-windows6 passes the HLK test suite on that platform. In the meanwhile we recommend Windows Server 2016 users to avoid installing OpenVPN/tap-windows6 driver on hosts where all users can't be trusted. Users of Windows 7-10 and Server 2012r2 are recommended to update to latest installers as soon as possible.

The Windows installers are bundled with OpenVPN-GUI - its source code is available on its project page and as tarballs on our alternative download server. This is primarily a maintenance release with minor bugfixes and improvements, and one security relevant fix for the Windows Interactive Service. Windows installer includes updated OpenVPN GUI and OpenSSL. Installer I601 included tap-windows6 driver which had one security fix and dropped Windows Vista support. However, in installer I602 we had to revert back to tap-windows due to driver getting reject on freshly installed Windows 10 rev 1607 and later when Secure Boot was enabled. The failure was due to the new, more strict driver signing requirements. The version of the driver is in the process of getting approved and signed by Microsoft and will be bundled in an upcoming Windows installer.
