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've being having trouble with one set of images during normalization the quality score changes to infinity symbol integrate and the snr and noise  reads nan-0 nan-0 nan-0 on all but my ref frame which reads  quality 143.73 ref snr and noise 4.5571e+00- 8.3523e-04  5.8484e+00 8.8900e-04   infinity -0. Each sub I pull up looks fine but the stacked image is blank.I am running a mac and app ver 1.082
Oeh I've seen this one before. Could you try with the latest APP 1.083? If it still shows, then there may be something with the calibration files.
@vincent-mod It is something with the calibration data. Seems to work fine until the normalization step, then things go sideways. I tried to update I get APP can't be opened because Apple cannot check it for malicious software.
You'd have to go into your security settings on MacOS and allow APP, we will address this in an upcoming release so it shouldn't be needed anymore.
Other than that, did you test not using calibration files? If that works, you can add bias, check again, then flats, check again and then darks. To see where it's causing an issue. After first testing the new APP version of course.
I traced my troubles my dark frames everything seems to be fine nowÂ
