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 am hoping someone can help, or at least provide me info on how I can determine the issues I have been having with APP after upgrading to the 2.0 BETA.
I am running Ubuntu 20.04, system is updated. I am running a 12 Gen I9 with 128 GIG of memory. I am running the software and processing data that resides on 6T of NVME Gen 4 drives. Graphics card is GForce 3080.
I have done the obvious things like uninstall, reinstall the software, insure I am at correct versions of libs.
The issues i see are APP just stop processing, it will get to about 80% and stall. The other issue is at times, it just hard freezes the machine, and several times it caused the machine to reboot.
The data set that I can constantly get it to fail (Lock up the Linux machine) is 60 frames of NGC7380 that was done over 2 nights. Not even close to the largest data set that I have processed with APP. However, without fail, when I try to process this data from the 2 nights, during integration my machine hard freeze's and requires a reset of the machine.
I can not even say how frustrating this is, and how long it takes or my machine to check drives and restart. I can not find any errors logged. Tonight I will rollback to the version to see if these issues can be reproduced.
Well like anything, ask a question, try a few more things out, and solutions, well at least for the Freezing while processing this data.
I reverted back to the stable version, and it was able to process with no errors, however the final results looks like someone blasted half of it with light. This caused me to go back and examine the frames. What I found was somehow I had half an image, the top half was fine, the bottom half was all white.
I removed this image and reprocessed and once I was happy with results, I installed the BETA 4 and ran the same process without the bad image. I was able to process the data just fine. So, not sure why this half image caused a lockup, but I have the data and if needed I can provide.
