The OpenVPN community project team is proud to release OpenVPN 2.6_rc1.
This is the first release candidate (and the third beta release) for
the feature release 2.6.0.

Changes since Beta 2:

* Officially deprecate NTLMv1 proxy auth method in 2.6. Will be removed in 2.7.
* Support unlimited number of connection entries and remote entries.
* New management commands to enumerate and list remote entries.
* Various bugfixes, see

Windows MSI changes since Beta 2:
* Included openvpn-gui updated to See
  * New feature: Connections active on exit/logout are now automatically 
restarted in the next session of the GUI
* Windows installers are now built with Visual Studio 17 2022 (previously built 
with VS 16 2019)

Some highlights of 2.6.0 are:

* 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.
* Reworked TLS handshake, making OpenVPN immune to replay-packet state 
exhaustion attacks.
* Added --peer-fingerprint mode for a more simplistic certificate setup and 
* Improved protocol negotiation, leading to faster connection setup.

More details can be found in the Changes document:

common problems encountered when using OpenVPN with OpenSSL 3)
