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.
Are Bias nessary if I use Dark Flats? I am using both at the moment, but read that both together can cause more harm than help supress noise.
Also, are Darks unnessary if I use a modern cooled astrocamera like ASI2600MC that has no amp glow?
I dither and use BPM.

@digitaliz-se Hi again,
Regarding using Bias when also using Dark Flats: if the dark flats have the same temperature, gain, offset and exposure time as the flats then you will not need bias.
Regarding using darks, if you create the BPM using warm darks with a long exposure time and if you dither well enough, then darks are not needed when processing the lights, indeed. However, you may want to check the integration results and make sure that no hot pixels are visible in them.

Ok,
Thanks!
@digitaliz-se Sorry, I made a mistake. In order to be able to perform flat field calibration properly, APP needs either bias or darks as well. This is necessary for subtraction of the bias pedestal. So as a minimum bias is necessary.
