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.
[Solved] Cannot open APP today. Stuck on 'Initializing OpenGL'.
As the title says. I have a 2020 M1 Mac and Sonoma 14.1, running beta 26 of APP.
APP has worked fine for months, but today it is stuck on 'Initializing OpenGL' at the splash screen forever, while the process is using 21% of the CPU doing... who knows what.
I haven't made any changes to my Mac.
Restarting the Mac does not fix it.
EDIT by Mabula : solved with version 2.0.0-beta28

Thank you for the error report, the error which is thrown seems to be caused by our development platform, not by our code at first sight... I will check if there are known problems with our development platform and the latest macOS updates 😉
Thank you, clearly, this error is in macOS Sonoma and not in APP's code, is there a way to revert the sonoma updates? I am not quite sure if apple even allows this ?
The error seems to indicate that Metal is still used as well... did you first uninstall the previous APP version before installing beta27? Metal should have been disabled.

That is awesome ! With beta28 for you? or perhaps with a new macOS update? Please be aware that the issue is caused by a broken metal framework in macOS Sonoma, and Apple will likely fix it in a newer update.
