Is Scapple Still Being Developed?

I read somewhere on the internet that this software is no longer being developed and has been abandoned. Is this true? I downloaded the trial a few days ago and have been impressed by how it functions as a brainstorming tool. It would be a great shame if it was no longer developed, I’m sure there are still many things which could be done with the program, especially keeping up its compatibility with new updates of Scrivener and any Windows or Mac OS changes. Although the clean, pared down functionality is a main part of its attraction, I do agree with others who’ve asked for the option of coloured and otherwise formatible connector lines. I like to brainstorm at speed, then look at the pattern as a whole to make certain elements more important, or to establish different types of relationship.
I do hope that the developers haven’t abandoned Scapple.
