Apr 9 2026 APP 2.0.0-beta40 has been released !

It has a major performance boost of 30-50% over 2.0.0-beta39 from calibration to integration, for mosaics even faster! 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. Improved Outlier Rejection with LN 2.0 rejection. macOS CMD+A works now in file chooser ! And more, all will be added to the release notes in the coming hours...

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 get this error (see attached screenshot) when integrating and LNC is anything but off.  Is this a problem with my data or workflow?

Hi @geordan,

This shouldn't be a problem with your data or workflow.

But it's helpfull if you provide more information:

  • how many frames are you integrating?
  • did you enable outlier rejection in integration? If so, which filter was chosen?

I think it could be related to a bug in the LN rejection filters, did you enable this by any chance?

I will work on upgrading LNC and the LN filters soon to solve this error.
