  • PolarSSL support as a drop-in replacement for OpenSSL
  • New plug-in API providing direct certificate access, improved logging API and easier to extend in the future
  • Added 'dev_type' environment variable to scripts and plug-ins - which is set to 'TUN' or 'TAP'

  • New feature: --x509-username-field, where other X.509v3 fields can be used for the authentication instead of Common Name
  • Improved client-kill management interface command
  • Improved UTF-8 support - and added --compat-names to provide backwards compatibility with older scripts/plug-ins
  • Improved auth-pam with COMMONNAME support, passing the certificate's common name in the PAM conversation
  • More options can now be used inside <connection> blocks

    • "generic": cross-compile on *NIX platforms (e.g. Linux -> Windows)
    • "msvc": build using MSVC on Windows
    • "windows-nsis": generate Windows installers on *NIX

These changes have resulted in a number of user-visible changes:

  • "easy-rsa" and "tap-windows" removed from the OpenVPN Git tree
  • All Windows executables and libraries cross-compiled with mingw_w64 and signed
  • Rewrite of the openvpn autotools buildsystem

In addition, there a number of changes not related to the above:

  • Many bugfixes
  • Stabilized the PolarSSL support
  • Enabled IPv6 support on OSX
  • General code cleanup
  • Improved UTF-8 support in Windows

OpenVPN 2.3-alpha1

This release includes a large number of new features:

  • Complete IPv6 support, both transport and payload
  • Optional PolarSSL support (build time configuration)
  • Improved plug-in API (v3) which can more easily be expanded in the future. Includes support for direct access to X.509 certificate data in plug-ins
  • New build-time configuration option: --enable-lzo-stub - Clients tell the server if they support LZO or not, and server can automatically disable LZO for that client.
  • New OpenVPN-GUI
  • New options / updated options
    • --stale-routes-check: remove routes that haven't had activity recently
    • --client-nat: one-to-one NAT to avoid IP address conflicts between local and remote networks
    • --extra-certs: certificates which completes the CA chain, without trusting these certificates
    • --verify-hash: Fingerprint matching on level-1 certificates
    • --memstats: Write live usage stats to memory mapped binary files
    • --crl-verify directory mode: file names in this dir which matching the serial numbers are treated as a revoked certificate. These files itself may be empty, as it is only done a match against the file name.
  • Management interface improvements
    • New option --management-external-key: Load RSA keys via management interface
    • New option --management-up-down: notify management interface on tunnel up/down events
    • New management command for servers: client-kill
    • New management command for clients: auth-token provides a feature to avoid storing passwords in memory and use a temporary token as an alternative to passing the password.
    • New management command for clients: remote which can override the configured --remote options

Many enhancements are also included:

  • Management command for server, status, can report username for each connected user (requires status log version >= 2)
  • UTF-8 support for certificate fields
  • Windows UTF-8 support: Filenames may now contain wide characters and environment variables handled as UCS-2 characters
  • Fixed client issues with DHCP Router option extraction/deletion with layer 2 DHCP proxies.
  • Added "on-link" routes on Linux. This solves --redirect-gateway issues where routes are set up with devices instead of IP addresses
  • Several configuration options are now supported inside <connection> blocks
  • Add extv3 X509 field support to --x509-username-field
  • Several man page updates

A few changes have been made which may affect existing installations:

  • 'echo' options will no longer be written to log files and will only be available via the management interface.
  • The certificate strings have changed syntax to the new standard provided newer OpenSSL APIs. Earlier the format was:

/CN=Common Name/O=Organisation/L=Location

The new format will look like:

CN=Common Name, O=Organisation, L=Location

This change impacts plug-ins, scripts and --tls-remote which parses these certificate strings.
