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.

And to add:
Beta6 works OK
Beta7 does not work (does not start)
Beta8 does not work (does not start)
@itarchitectkev Same for me with Opensuse 15.4. Mabula is working on that issue. I reported it on Dec. 9th.
Hi @itarchitectkev & @juergenn,
Thank you both for reporting this issue on Linux.
FYI: All is fine on our Linux test systems which are Fedora28 and Mint20 and the thrown error is related to our implementation of using the native file choosers since 2.0.0-beta7. I would almost think that your Linux distributions are missing an OS dependency in the window manager somehow, so I will be investigating:
- adjusting code so it just works
- or finding the required OS dependency so it will work on your systems.
Will keep you updated, this issue is now at the top of our ToDo list to get to 2.0.0-stable.

I have solved this issue @itarchitectkev &Â @juergenn and will soon provide a fixed version 
Mabula
Great to hear 🙂

Hi @juergenn & @itarchitectkev,
Please try 2.0.0-beta9 which has just been released. It should work now on your linux installations 😉
Mabula
I can confirm this is now working on Ubuntu 22.04. Thanks!
@mabula-admin :
I can also confirm that Beta 9 is working for me with OpenSuse 15.4, thank you Mabula!
Excellent ! Thank you all for your quick feedback 🙂 it's my pleasure !
