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.
Hello Mabula, I am getting around to doing some processing again, and very much enjoying the changes in 1.0.61. They have really helped the flow.
I had reason to re-install the application, and happened to notice that it required all 32 bit libraries. This likely has always been the case, but it made me curious if you had tried the 64 bit versions?
Thanks
Jim

Hi Jim @xsnrg,
APP 1.062 has been released today 😉 so check it out...
This is particular to installing the RPM package on Linux distributions. The RPM package manager indicates which dependencies are needed for APP to work.
These 32bits libraries are not selected or controlled by me or the APP code base, they have to do with 64bits Java dependencies in this case. It sounds strange ( I know, because I think it's strange myself) but apparently some of these packages are only available in 32bits in the RPM repositories.
So, while APP is fully 64bits, these 32bits libraries will not break or bring down APP and they are simply needed since 64bits versions of the dependencies are not available.
It might be different with different Linux distributions, I haven't tested them all (there are quite a lot...).
On which Linux distribution are you?
Probably, when I upgrade to Java 9 or 10 with APP, this will chance as well I think.
Cheers,
Mabula
I certainly will check out 1.0.62, thanks for the hard work!
This is with Fedora 28, and it is odd that is pulls the 32 bit libs in as the 64 bit versions of these are already installed in the system.
Hi Jim @xsnrg,
😉
Okay thank you for the info, I will do more investigation on this then. I didn't select those libraries as dependencies, the java RPM packager did, so I will try to found it why it only wants the 32bits versions of these packages.
APP does work correctly on your Fedora 28 system, right?
Mabula
