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.
is there a way to add subs to an already integrated process?
let's assume I stacked light frames (with corresponding calibration). I want to add another session with new subs but use only the result from the earlier integration in order to save integration time. is that possible?
There is yes, just load in the integrated lights and add the new data as well. I would first get enough extra data and calibration data to make an integration of that and then combine them.

If I may expand on this a bit: On M31 I have Ha, L, R, G, and B integrations I am happy with qualty-wise. However the total times could be higher, especially the L data.
Next year could could I shoot more Lights, calibrate them, and the add the new L channel integration to the old L intgration?
If so, would this be done in the Integration tab, or the RGB Combine tool? Presumably I would use the Registration tab 4 to register New to Old.
Conceptually then the Integration file is a Master Light. This would imply good news for my disk management as I could delete individual subs once I have good integration files, in the same fashion as Master Darks, Bias, and Flats.Â
You can yes. Given your integrations are calibrated well with enough calibration frames, you should have clean integrations with good signal so those will add nicely when stacked. Theoretically it's better to stack all subframes, but personally I haven't noticed a massive difference in that sense. I would test it for yourself first as well.
You simply load your integrations as lights, without calibration data and integrate.
