OpenVPN 2.7_beta1 -- Released 04 September 2025

The OpenVPN community project team is proud to release OpenVPN 2.7_beta1. This is the first 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_alpha3:

• Introduction of route_redirect_gateway_ipv4 and _ipv6 env variables
• PUSH_UPDATE server support (via management interface)
• Rewrite of the management interface "bytecount" infastructure to better interact with DCO

Important bug fixes since 2.7_alpha3:

• Bugfixes in --dns-updown script for linux systems using resolvconf
• A large number of signed/unsigned related warnings have been fixed

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.

Windows MSI changes since 2.7_alpha3:

• Included dco-win driver updated to 2.7.1
  • add support for multipeer stats
• Built against OpenSSL 3.5.1
• Included openvpn-gui 11.55.0.0

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)

For Community-maintained packages for Linux distributions see OpenVPN Software Repositories.
