We're getting close to a 1.5 final release... I would like to nominate OpenVPN 1.5-beta14 to be release candidate 1 for OpenVPN 1.5. Beta14 has been out for a week or so without any bugs reported thus far. If you think you've found a bug, please report it ASAP.
There have been a number of reports about certain things working on early versions of the beta cycle running on Windows, i.e. before beta 8 or 9, then not working on later versions. Most of these problems have been attributed to the new --ip-win32 option which changed default behavior. The default is now --ip-win32 ipapi, but two other methods exist, "netsh" and "manual" -- please consult the man page and try these other options if you are running the Windows version of the beta and experienced problems after upgrading to recent versions of OpenVPN, i.e. beta12 or greater. If you follow the CVS, I've merged beta14 back into the HEAD branch as 1.5-rc1, and started a new branch BETA20 for ongoing development of major new features such as forking server support and point-to-multipoint mode which will ultimately be released as OpenVPN 2.0. Bug fixes and minor or moderate feature additions will go into the HEAD branch for release on a shorter development & test cycle. James
