I changed the versioning file from txt to xml. The advantage is that I have more control over the code because I serialize and deserialize with the help of a special class. This way, it’s enough to deserialize the versioning data once, in order to obtain and easily use all information stored in it. Of course, the older versions with the versioning file as txt won’t work with this one. Even more, the updater code is not completed yet. It is possible that some nightly builds had old updater code. If you have problems starting NaroCAD in the last period, it might be due to unfinished code. If you have such problems, it is best to reinstall NaroCAD. Also be aware that nightly builds might not always work correctly due to unfinished tools.
