Yes you can expect maintenance releases for Dolphin. As you know Dolphin is currently an excellent tool for building Win32 based applications and one wouldn't expect that support for Win32 is going away anytime soon in the Windows OS. So, it shouldn't be too difficult for us to keep Dolphin running under future versions of Windows providing the Win32 base remains supported. Indeed, we have to do this for applications that we have running in house.
The announcement back in August was intended to convey the fact that, given the poor commercial performance of Dolphin, we just do not have the resources to commit to a major development programme; the sort that would be required to port Dolphin to .NET.
So, I guess nothing has changed but perhaps I didn't explain the situation clearly enough back in August.
This is great news!
