OpenVPN 2.7_beta3 -- Released 13 October 2025

The OpenVPN community project team is proud to release OpenVPN 2.7_beta3. This is the third Beta release for the feature release 2.7.0. As the Beta name implies this is an early release build, it is not intended for production use.

Feature changes since 2.7_beta2:

• improvements on PUSH_UPDATE handling on the server side
• improve "recursive routing checks", prepare the way for a policy-based setup where "packets to VPN server" could end up in the tunnel without interfering with OpenVPN operations
• add support for "epoch" data format to DCO on Windows
• clean up and remove outdated stuff from COPYING

Important bug fixes since 2.7_beta2:

• bugfixes reconnect and PUSH_UPDATE handling on the client side (notably handling of ifconfig/ifconfig-ipv6/redirect-gateway ipv6 if the server is not always pushing the same address families)

For a list of all changes see the git log.

Highlights of 2.7 include:

• Multi-socket support for servers -- Handle multiple addresses/ports/protocols within one server
• Improved Client support for DNS options
  • Client implementations for Linux/BSD/macOS, included with the default install
  • New client implementation for Windows, adding support for features like split DNS and DNSSEC
• Architectural improvements on Windows
  • The block-local flag is now enforced with WFP filters
  • Windows network adapters are now generated on demand
  • Windows automatic service now runs as an unpriviledged user
  • Support for server mode in win-dco driver
  • Note: Support for the wintun driver has been removed. win-dco is now the default, tap-windows6 is the fallback solution for use-cases not covered by win-dco.
• Improved data channel
  • Enforcement of AES-GCM usage limit
  • Epoch data keys and packet format
• Support for new upstream DCO Linux kernel module
  • This release supports the new ovpn DCO Linux kernel module which will be available in future upstream Linux kernel releases. Backports of the new module to current kernels are available via the ovpn-backports project.
• Client-side support for new PUSH_UPDATE control-channel message
  • This allows servers to send updates to options like routing and DNS config without triggering a reconnect.
• PUSH_UPDATE server support (minimal)
  • New management interface commands push-update-broad and push-update-cid to send PUSH_UPDATE option updates.
• TLS 1.3 support with bleeding-edge mbedTLS versions
• Two new environment variables have been introduced to communicate desired default gateway redirection to plugins like Network Manager.
• Support for Epoch data channel on Windows, using the win-dco driver (2.8.0+)
• "Recursive Routing" check is now more granular, and will only drop packets-in-tunnel if destination IP, protocol and port matches with those needed to reach the VPN server.
• COPYING: license details only relevant to our Windows installers havebeen updated and moved to the openvpn-build repo

For details see Changes.rst

Windows MSI changes since 2.7_beta2:

• Built against OpenSSL 3.6.0
• Included openvpn-gui updated to 11.56.0.0
• Included win-dco driver updated to 2.8.0

OpenVPN 2.6.15 -- Released 22 September 2025

The OpenVPN community project team is proud to release OpenVPN 2.6.15. This is a bugfix release.

For details see Changes.rst

Bug fixes:

• On Windows, do not use "wmic.exe" any longer to set DNS search domain (discontinued by Microsoft), use "powershell" fragment instead.
• On Windows, logging to the windows event log has been improved (and logging of GetLastError() strings repaired). To make this work, a new "openvpnmsgserv.dll" library is now installed and registered.
• DNS domain names are now strictly validated with a positive-list of allowed characters (including UTF-8 high-bit-set bytes) before being handed to powershell.
• Apply more checks to incoming TLS handshake packets before creating new state - namely, verify message ID / acked ID for "valid range for an initial packet". This fixes a problem with clients that float very early but send control channel packet from the pre-float IP (Github: OpenVPN/openvpn#704, backported from 2.7_beta1).
• Backport handling of client float notifications on FreeBSD 14/STABLE DCO (see https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=289303)
• Update GPL license text to latest version from FSF
• On Linux, on interfaces where applicable, OpenVPN explicitly configures the broadcast address again. This was dropped for 2.6.0 "because computers are smart and can do it themselves", but the kernel netlink interface isn't, and will install "0.0.0.0". This does not normally matter, but for broadcast-based applications that get the address to use from "ifconfig", this change repairs functionality.

Windows MSI changes since 2.6.14-I004:

• Built against OpenSSL 3.5.3
• Included openvpn-gui updated to 11.56.0.0
  • Fix "Cannot open the System Tray Menu with Keyboard" (Github: OpenVPN/openvpn-gui#763)
