Super timely post as I just uploaded a 1.5 Maintenance Release and a new 1.6 alpha.
Lots of new features and improvements in both (see CHANGELOG file for details) vs 1.3.5 and even 1.4. If you're doing narrowband, have a look at the 1.6 alphas, as you can now choose from a great number of popular color blends ("Matrix" option the the Color module) with the click of a button
without having to recomposite and redo your processing. SHO, HOS, Duoband and more are supported.
Clear skies!
PS Lovely M8!
