Hello, my name is Roman Telezhynskyi and was the original author and the maintainer of Valentina project.
I just want to clarify several things mostly because you read only the forum i do not control anymore. Especially because people there very hostile to me. > My understanding is that the original author will no longer develop the program (at least not as a FLOSS project) and that the only surviving FLOSS project is the forked one, but I may be mistaken. You are wrong. I decided to fork my work to reduce influence from people who do not share my point of view. It will stay open source, i don't have plans to close it. At least until i have enough resources to continue developing. Some more info for you guys to decide which fork to support. I made big part of the code. And thing is, they don't have developers. None. This project has very few contributors, interest in pattern making is very very rare among developers as i know. So, think twice before supporting the project in coma. Their leader good woman, but don't want to be a maintainer or developer (doesn't know C++). They even cannot find people to backport simple patches with bug fixes i made. Just go to their github repo page. Check their commits, well, if you know something about developing you will understand what i mean. Another important thing. Two projects not compatible anymore. Because i continue developing the file format, my version still can open all patterns, but their version not anymore. Also i support package for debian, but don't know how good it is. No one ever gave me feedback. God, i wish i was the problem here and after my leaving it has a lot developers and very active community. But reality is different. :(
