I installed 1.4.3.0 on several PCs without problems and will update them to 1.4.3.1 in the next days.
But one question: Can we get an IPv6 enabled version please ? Or is it already available an I missed something ?
After more 1 000 000 (one million) views on forum for 1.5.0.x development versions... and 1.6.1.0, 1.6.3.0-dev versions
A new stable version, UltraVNC 1.6.4.0 and UltraVNC SC 1.6.4.0 have been released: https://forum.uvnc.com/viewtopic.php?t=38095

Re: ipv6 mode grayed out in server settings
Hi Vort,
thanks for your effort to support ipv6 with your patches. Nevertheless, according to my knowlegde 0225:9a7e:5c30:662e:317b:0ccb:0f93:e024 is not a valid format for an ipv6 address. According to this site

Re: 1.2.3.0 preview
Perhaps a dummy monitor plug ( display emulator ) is the easiest solution ?

Re: 1.2.24 Release ( web release for 15/03/2019)
Just did a short test today:
I was able to send and receive files to and from the server via an IPv6 connection. Nevertheless, I only used small files with a size of a few 100mb for this test. Both machines are on Windows 10 1903 Pro 64bit ( Build 18362.418 )

Re: 1.2.24 Release ( web release for 15/03/2019)
I can happily confirm that IPv6 now, at least locally tested in my LAN, works correct again. I will do a real world test over the internet tomorrow.
Many thx for your effort
The real world test over the internet also showed that Ipv6 connections do work again.

Re: 1.2.24 Release ( web release for 15/03/2019)
Sorry for bothering you, Rudi, but I think you forgot to recompile the IPv6 enabled binaries ? :wink:
I am asking for them because here in Germany, the cable companies mostly provide access to the internet using ds-lite. And therefore it is very helpful to have an actual and working UVNC version ...
