Mar 28 2026 APP 2.0.0-beta40 will be released in 7 days.
It did take a long time to have the work finished on this and it will have a major performance boost of 30-50% over 2.0.0-beta39 from calibration to integration. We extensively optimized many critical parts of APP. All has been tested to guarantee correct optimizations. Drizzle and image resampling is much faster for instance, those modules have been completely rewritten. Much less memory usage. LNC 2.0 will be released which works much better and faster than LNC in it's current state. And more, all will be added to the release notes in the coming weeks...
Update on the 2.0.0 release & the full manual
We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version.
Once 2.0.0 is released, the price for APP will increase. Owner's license holders will not need to pay an upgrade fee to use 2.0.0, neither do Renter's license holders.
I seem to have a problem with my flats in the sense that they do not correct vignetting or take out some artifacts in the optical train (that don't seem to be dust bunnies). I image using a 300mm lens and a full spectrum modded Pentax K-5. I have taken the calibration frames (50 bias, 20 darks and 20 flats) and the flats (see attachment) also show the vignetting and artifacts, but don't remove these from the final stacked image. Does anyone know what may cause this? I will take the flats in the morning with the white t-shirt method and the camera in Av mode using the same ISO and no changes to the optical train.

Many thanks in advance,

Take a look at the file name after you do the calibration step. If it only shows CA next to the name it's not applying ANY calibration frames. Recently I've been having this issue with APP and I don't know how to fix it.Â
