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.
Hi Neil - I've seen this happen when I've deleted or renamed the working directory (or a parent directory). As soon as I choose a valid working directory, APP reports the correct amount of space available.

Hi Neil & Scott,
Yes indeed, the 0GB space hard drive bug happens when you remove the directory from the file system, that is set as the current work directory. I will fix this now 😉 so it makes the release of 1.056..

Hi Neil,
It will be fixed in 1.056 ;-), the zero space won't show anymore. If you remove a folder that is set as the work directory, APP will now automatically set the work directory to your Operatings Systems user folder, so will show the free space of the drive on which your user directory is installed, and it will ask you if you want to select a new work directory.
