Most of my projects are on github ( https://github.com/uwerat ) and I will indeed move the repository sooner or later. But I might continue using sourceforge for releases, mailing list, feature requests and bugs - let's see.

The next release will drop support for very outdated Qt versions ( < Qt 5.6 ) what changes my opinion on this issue. So yes - Qwt 7.x will use cmake as primary build system.

Why does the curve behave this way when using NaN values?

Using NaN values to split a curve into segments is not implemened. You have to use one curve per segment or overload drawCurve/drawSeries where you do the segments

Incompatybility with Qt 6.8

Nobody suggested that: the other bug reports indicate, that the problem has been fixed in Qwt 6.3.0. And for the record: AFAIR it was about an incompatibility between Qt versions - nothing I could have known in advance when releasing Qwt 6.2.x. So again: are you sure that you are running Qwt 6.3 ?
