UPDATE FROM MABULA
I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred  after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.
Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.
APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46. Â Before I release it, I will make sure that everything is working properly and then I will release it.
I am currently using another product for my astrophoto's. I tried APP about 9 months ago and decided to wait until APP had more features / capabilities in gradient removal, noise removal and masks. Where can I find a detailed list features / capabilities for the current release?
I don't think there is a dedicted feature list yet, this will probably be part of the upcoming documentation. Gradient removal is the 'light pollution filter and LNC', noise removal and masks are not part of it yet. The tools almost everyone has high on their list are; noise removal, HDR, comet registration and deconvolution. Mabula will work on those first, I think the GPU acceleration has top priority now and these tools will come after that.
