This page outlines the release process for OpenVPN 2.x. It also works as a release checklist.

External systems involved

  • Microsoft Partner Portal
    • For attestation signing Windows drivers
  • Windows signing computer
    • For Authenticode signing drivers meant for Windows 7/8
    • For building Windows drivers such as tap-windows6
  • The staging website
  • The production website

Build tools


The openvpn-vagrant repository contains VirtualBox/Vagrant setup that can help with the release, see below.


Many release preparations can be automated with openvpn-release-scripts.


Ubuntu and Debian packages are built with sbuild_wrapper. It is available as a VirtualBox / Vagrant VM ("sbuild") in openvpn-vagrant.


Windows installer are built with openvpn-build. The easiest way is to use the build system is to use the VirtualBox / Vagrant VM from openvpn-vagrant:

  • msibuilder: for OpenVPN 2.6 (OpenSSL 3)
  • msibuilder25: for OpenVPN 2.5 (OpenSSL 1.1.1x)

Pre-release checklist

Notifying external entities

OpenVPN Inc website team

The OpenVPN Inc. website team makes weekly website releases. Any changes to the website should be made to the staging web server first, then released in production. In case of emergency releases an off the cycle website release can be made, but that needs to be coordinated with the website team.

OpenVPN Inc marketing

OpenVPN Inc. marketing people should be notified 7 days prior to a new major release is about to be released. At minimum, allow for 48 hours.

Access Server team

OpenVPN Inc. Access server team should be notified prior to a release that affects the Access Server. This means primarily releases with security fixes.

Package maintainers

Downstream package maintainers (Debian, Ubuntu, Red Hat, etc) should be notified about releases with major security fixes. This is easiest to do via the oss-security mailing list.

All website changes have to go through the usual website release process (staging -> production). This means that package publishing should generally happen at the same time as website releases.

The package release process is the following:

  • Copy release files to with openvpn-release-scripts

Release announcements should be sent once packages have been published and the website updated:

  • Mailing lists (attach changelog)

Tag release and push tags to Git for all repositories that changed:

  • tap-windows6 (when needed)

  • In openvpn-build/windows-msi use PRODUCT_VERSION 2.5.0xx for release/2.5 and 2.5.1xx for release/2.6+. This ensures smooth upgrades.
  • Remove GitHub tokens if you pushed to Git from the Windows signing computer
