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'm having crashes and or errors in the last 2 days. Previously with release 29, no issues until yesterday. I downloaded release 30 and no change. Some errors if I actually get to integration result in the program closing. I'm using a Windows 10 PC.
One frequent error is as follows:
Encountered error in module:Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â
FileDetailListUpdater
 Error message:
java.lang.IndexOutOfBoundsException: pos < flushedPos!
Â
Cause:
pos < flushedPos!
java.desktop/javax.imageio.stream.FileImageInputStream.seek(Unknown Source)
oX.a(BitReader.java:71)
oZ.seek(BufferedRawImageInputStreamImpl.java:128)
oO.<init>(Exif.java:73)
Â
So what could have changed overnight?
Edit by Mabula: below new topic added here, since it is the same topic.
Â
Today I uninstalled APP and then reinstalled version 29 (since it was the last working version).Â
Loaded some lights, darks and bias files. Upon "create masters & assign to lights" it ran for a few seconds and crashed, closing the program.Â
I checked the log file and there's nothing that stands out.Â
I also tried again using the CPU instead of openG4L with the same result. Tried again dropping the theads to 6 from 8 with same crash.Â
Maybe it's my data that's corrupt? Is there anywhere I can download a sample file for lights, darks and bias?Â
Hi Colin @astrocirrusp,
Thank you very much for reporting this issue.
The error:
Encountered error in module:
FileDetailListUpdater
Error message:
java.lang.IndexOutOfBoundsException: pos < flushedPos!
Cause:
pos < flushedPos!
java.desktop/javax.imageio.stream.FileImageInputStream.seek(Unknown Source)
oX.a(BitReader.java:71)
oZ.seek(BufferedRawImageInputStreamImpl.java:128)
oO.<init>(Exif.java:73)
indicates to me that one or more files that you load into APP are probably corrupt somehow, especially since before a couple of days ago all was fine right?
Can you download and try this dataset from this tutorial: https://www.astropixelprocessor.com/complete-lrgb-tutorial-of-ngc292-the-small-magellanic-cloud-by-christian-sasse-itelescope-net-new-version-app-1-081/
The link to download the data is here: https://apastropixelprocessordl.s3.eu-central-1.amazonaws.com/iTelescopeNGC292Tutorial/RawLights-CalibrationFrames.zip
Can you load and process these files without issues? If so, then it is vey likely that one or more of your files are corrupt. If not, then please let me know. I will then give you upload instructions so I can test what is going on with your data.

Thank you for your quick reply. You were correct, my data is corrupt. I loaded your sample data and it works like a charm! Our recent cloudy skies have not allowed me to get out and collect new data so I was unable to test.
I understand your workload is huge right now and appreciate your help on this issue.
Cheers...Colin
