Note that OpenVPN 2.5.x is in Old Stable Support status (see SupportedVersions). This usually means that we do not provide updated Windows Installers anymore, even for security fixes. Since this release fixes several issues specific to the Windows platform we decided to provide installers anyway. This does not change the support status of 2.5.x branch. We might not provide security updates for issues found in the future. We recommend that everyone switch to the 2.6.x versions of installers as soon as possible.
