This is mainly a bug fix release for the reported bugs in beta47. In addition it has a significant User Interface performance improvement noticable when you need to process 1000s of images in APP.
2026-10-03 APP 2.0.0-beta47 has been released !
This is a very big release... many code optimizations/rewrites, many parts of APP are much faster and more precise, especially star analysis and registration are much faster ! Big mosaics will go much faster 🙂
And we introduce a new preview filter, which includes the new Adaptive Deep Sky Stretch and a General Levels Stretch, this has been long over due. The old preview filter (the panel on the right side to stretch and preview your data) has not been updated for a couple of years and it is a critical part of any APP session.
Adaptive Deep Sky Stretch or ADSS is a much more intuitive stretch algorithm. It is also color preserving (which is a great new addition in itself ! ) which means that the highlights are no longer bleached, color is maintained from the linear data while stretching. You can simply stretch your data using the sky background level and signal width sliders which work much easier and more intuitive. You no longer need to fiddle with the old complicated sliders with zoom buttons. All the zoom buttons for the sliders are made redundant. And you can enter slider values in the slider value fields yourself. I will make a youtube video in the coming days to explain and fully introduce ADSS. Once the video is ready, it will be highlighted on the forum.
RGB Combine upgrade !. The RGB Combine Tool has been rewritten mostly. The tool is faster and easier to use and most importantly, the Luminance slider to inject a luminance channel or channels into the RGB composite is now working correctly. It no longer bleaches the RGB colors. Combined with the new ADSS preview, you will get much better and easier great composites with great color! I will also explain this in a new youtube video.
I have 2.0 v20 updated. APP will not allow me to load files from my documents, all pictures are just greyed out and can't select them. This is the first time this has ever happened? What should I do?
From which version did you upgrade? Have you tried completely removing APP first and then installing beta20 ? It sounds like something is messed up with your privileges running APP on your system. On which Operating System does this occur?
@mabula-admin I upgraded from v17 but had the same issue (previously functioning normally last I used it about 6 weeks ago). I’m running OS Ventura 13.4.1. I’ve gone to privacy options and don’t have any permissions to give. Still troubleshooting…thanks for the quick reply.
Okay, that is great to hear. Please let us know if it happens again though. I have never seen this before. For my information, did you in fact re-install APP?
I think I know what happened, the File Chooser window in macOS should have a button with show/hide options, if you show the options, you can select a file format filter. In your case the file format filter was set in such a way that your ARW files could not be selected and thus they were greyed out. In your screenshot I do not see this show/hide options button and this can be caused by some setting in macOS I think. On my mac computers, the button is always there. The file format filter is set by default to be able to load all APP supported files. I guess a re-installation of APP fixed that for you?
