2026-10-09 APP 2.0.0-beta48 has been released !
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 installed version 1.075 Bata4 today. Directly after starting APP was told that GL4 (green) is active.
After loading a light frame the button changed to OpenGL (orange). A change to GL4 is no longer possible, not even by pressing the OpenGL button. Loading an image is now very slow.
Is there an error here?Â
Windows 10 Home
I have the same exact problem as well. Once I load a light frame GL4 turns from green to orange.
Thanks everyone for letting us know. I informed Mabula about it.
And I just got word he's aware of it and working on it.
Thank you very much for your feedback. Then I wish you a lot of success in solving the problem.
Greetings 😀Â

It should be, I have it on my Mac mini 2012. It's an issue with the beta and already fixed for the next release.
I have a similar problem with the official release version 1.075 I just installed. I am now unable to run under OpenGL (orange) but am forced to GL4 (green). I'm running Win 10, latest version, and Intel UHD Graphics 620 with latest drivers on a Toshiba Yoga 920. On previous versions I was able to run OpenGL. Display still works but appears slower. Any thoughts?
Mmm, not right away, is GL4 not simply OpenGL 4? If that's green it should indicate it works and clicking on it will deactivate OpenGL and that's why it's orange.
@vincent-mod
Ahh, I suppose GL4 could just be short for OpenGL 4... the pop-up help says if OpenGL is not supported then it will be orange, but upon further reading I see GL4 is simply the abbreviation. I appreciate the very quick response!
Yep, I agree that can be a bit confusing because of the different names for the same thing. Glad it is cleared up though!
