[Gmsh] Next stable release?

[Matthias Sedlmaier]

Hello Gmsh developers,
I plan to write an application, which uses Gmsh as an external process. 
Unfortunately, I can't use the current stable version because I need to 
create meshes forCalculiX. And that's why I wanted to ask if there is a 
rough estimate of when the new stable version will be released?
Should i start developing my code based on the latest nightly build or 
is it worth waiting for the next stable version?

Thanks in advancefor your answers.
Matthias
