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.
Hi,
With V2B1 release I seem to have a problem displaying images when switched to Open 4GL, see screen grab. The image is cropped, does not fill the available window space, and when I try to draw area select boxes, the box APP displays on the screen does not correlate with the mouse positions used when drawing. I have used the Open 4GL display option without problem on previous releases.
If I switch to CPU display the image displays as I would expect and area box display works correctly.
I am using a Lenovo X1 Carbon 6 laptop (i7 8550U procesor) running Windows 11. The system has Intel Iris graphics.
Â
Cosmetically I am very used to having the working image in centre screen. In my opinion it would be nice if this arrangement could be retained but as things stand the image window disappears each time a display adjustment is attempted. Maybe an 'always on top' option could be provided for this window?
On the other hand, I find the fonts etc used in new release mean thhe side bars are much slimmer thus providing a greater area for image display. A big improvement in my opinion.
Regards
Mike
Hi Mike @mestutters,
Thank you for reporting the OpenGL issue with this new 2.0.0-beta1.
Can you check the following for me:
- the exact graphical hardware
- the exact graphical driver that is installed on windows 11
I suspect that you might be using microsoft drivers instead of the proper manufacture graphical drivers, can this be the case? We now that the microsoft drivers are (very) poor for these intel on-board graphical chips... giving exactly issues like this.
I will check if we can add a selectbox to have the image viewer always on top 😉
Thank you very much for your feedback Mike

Hi,
I have the same problem on my Linux (OpenSuse Tumbleweed) with KDE. I am using Radeon graphics driver. CPU viewer works fine (although much slower).

Hi Karol,
Which version did you install? the HiDPI installer or the regular one?
Mabula
Lenovo X1 C6 lap-top is equipped with Intel UHD 620 GPU.Â
It is currently installed with:Â Intel HD Graphics Driver (Windows 10 Version 1709 or later) -10 [64] - 27.20.100.8476.
Looking at Lenovo web-site there is a slightly later driver available: 27.20.100.9749. I will try upgrading to this later today to see if it makes a difference.

Dear Mike,
Please check for a Windows 11 compatible driver, you are running windows 11 right?

Dear Mike,
Oh, i think I already know what the issue is. Can you check the windows configuration -> System -> Monitor/Screen -> scaling of text and apps? I think our new developmemt platform is not yet detecting the Scale ratio here...
Mabula
Hi,
I'm running screen at 2560 x 1440 resolution. Scaling is 175%.

Hi Mike @mestutters & @karolbe,
Thanks !
I have solved it for Windows, Linux and macOS ;-). It had to do with desktop scaling and I have now implemented a robust fix which will also work in multiple monitor setups with possible different desktop scalings and it works on all operating systems.
Will soon release 2.0.0-beta2 with the fix !

I was about to report this, but I see other people already have.
