UPDATE FROM MABULA
I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred  after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.
Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.
APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46. Â Before I release it, I will make sure that everything is working properly and then I will release it.
Astro Pixel Processor 2.0.0-beta46 release notes
- Improved Internal Memory configuration and improved performance as a consequence.
The latest beta's all had changes relating to memory controls, that means how much memory APP can use, how much memory it will reserve for usage and how much memory will be released back to the Operating System while processing. We have done more testing and beta46 probably has the final optimized configuration going forward for the 2.0 stable release. Beta46 will use quite a bit less memory than beta 43,44,45. It will compact it's memory usage now using the Shenandoah garbage collector from the OpenJDK development platform. The compact mode ensures that while APP receives memory allocations, APP will immediately clean things up and release the memory if possible. So instead of APP using a big part (30-70 %) of the computer's memory, beta46 will show much less usage and as a consequence, it will show better performance. Using more memory can actually be a drag on performance it turns out. We see several % performance improvement because of this change in several benchmarks.
All the optimizations that were implemented in the last year or so, gives APP a big performance boost and the old way of the memory controls that was used until beta39 became problematic. The memory could not be cleaned up in time because of the performance improvements, causing memory defragmentations and stalling of performance on big datasets. With Beta 46 this should definitely be a thing of the past and performance should continuously be good even on very big datasets.
- FIXED Set Save Directory
2.0.0-Beta45 had a regression bug where setting the Save Directory did not work as expected. This has been fixed. It was reported here: https://www.astropixelprocessor.com/community/windows/problem-setting-save-directory-in-app-2-0-0-beta-45/#post-34703
- FIXED 2.0.0-beta45 startup issue
Beta45 would not start on a computer that has less than 8 cpu threads. This has been fixed.
- FIXED ArrayIndexOutOfBounds Exception in SumSignalInCropWorkerÂ
As reported here https://www.astropixelprocessor.com/community/appreleases/beta-44-crashes-when-trying-to-register-existing-stacks/#post-34587 APP would throw an error in the SumSignalInCropWorker module if you try to normalize a multi-channel image with a monochrome reference image. This bug is a regression from previous optimizations and rewriting the normalization engine. It has now been properly fixed and you can normalize multi-banded images with a monochrome reference and vice versa.
- FIXED 2-panel mosaic works now in mosiac mode
As reported here https://www.astropixelprocessor.com/community/main-forum/2-panel-mosaic-error/#post-34674 it you would try to register a 2-panel mosaic in the mosaic mode, it would error with an ArrayIndexOutOfBoundsException. The data could still be registered though in normal mode. The mosaic mode works now as well.
