https://github.com/deepskystacker/DSS/releases/tag/4.2.0-Release

Changelog:
程式碼:
    Support for images from cameras that use the Fujitsu X-Trans sensor (new in 4.2.0 Beta 2).
    The image is converted to a 3 colour RGB image and interpolated using Frank Markesteijn's algorithm using LibRaw::Process().
    Please note that the interpolation is quite slow (about 40 seconds per image on my Core i7 laptop).
    The image is then imported as if it were a Foveon colour image.

    BSD 3 clause license file added.

    A fix was made to correct crashes caused by a thread-unsafe assignment in the smart pointer code.

    The "Stop" button on the progress dialogs should now actually work!

    The space key can now be used to check/uncheck images in the picture list.

    The user's default browser will be used instead of IE to open URLs.

    Miscellaneous code cleanups and performance improvements including Median-Kappa-Sigma processing.

Cheers
Tom

https://github.com/deepskystacker/DSS/releases/tag/4.2.1-Release

程式碼:
The main changes from 4.2.0 are:
1. Fixed a memory leak in the new code that uses LibRaw.
2. Further performance enhancements to Median-Kappa-Sigma processing (20% faster than 4.2.0).

Cheers
Tom

https://github.com/deepskystacker/DSS/releases/tag/4.2.2-Release

程式碼:
This release is all about performance, though other areas have been enhanced as well. The main changes since 4.2.1 are:
1.    Changes to star registration code to detect larger stars than before. Star radius of up to 50 pixels is now valid (it was 20 pixels). This was needed to accomodate higher resolution sensors.
2.    Allow larger star sizes to the specified in the Star Mask creation dialogue. Star diameter of up to 100 pixels is now allowed. This was needed to accomodate higher resolution sensors.
3.    OpenMP speedup of Star Mask image reading code.
4.    Huge speedup of final image display by using much larger rectangles and OpenMP speedup of the bitmap extraction code.
5.    Speed up star registration by updating progress indicator once every 25 iterations instead of each iteration.
6.    Computing Final Picture using Kappa-Sigma Clip processing is now about 50 times faster!
7.    Computing Final Picture using Auto Adaptive Weighted Average is now about 43 times faster!
8.    Auto-Adaptive Weighted Average now re-written completely. It should no longer produce whited out images or other strange results. Thanks to Michael A. Covington and Simon C. Smith for their immense help in locating references and getting this working. Thanks are also due to Dr. Peter B. Stetson who very kindly provided a web link to his original lecture notes, emailed a PDF copy of his original paper, and provided helpful guidance.
9.    Update LibRaw to 0.19.3.
10.   Reverted Entropy calculation code in CEntropyInfo::InitSquareEntropies() to NOT compute in parallel - some called code wasn't thread safe.
11.   Entropy Weighted Average complete stack of 50 lights is now about 20 times faster on my laptop, down from 4hrs 22min to 12min 55 sec.
12.   Bug fix - changing "Set the black point to 0" or "Use Camera White Balance" after an image was loaded didn't change the rendering.
13.   When loading raw files, check that the camera is listed in the LibRaw supported camera list. Issue a warning if not.
14.   User request to change the file open dialog to default to all supported image types including raw files.
15.   Three times performance improvement in star registration.
16.   As requested by Ray Butler, use relative paths in saved file lists while continuing to accept older file lists using absolute paths.
17.   Miscellaneous other performance tweaks.
18.   Display lens aperture information in the image lists for DeepSkyStacker and DeepSkyStackerLive.
19.   Don't check for LibRaw camera support if processing DNG file.

Cheers
Tom

https://github.com/deepskystacker/DSS/releases/tag/4.2.3-Release

程式碼:
The main changes in this release are:

1.   The 32 bit version will now run on Windows XP SP3. It is likely that the next release of DeepSkyStacker will not do so.
2.    The stacking settings dialog width has been increased to reduce or eliminate the need to scroll the tabs.
3.    Add .rw2 to list of RAW file extensions.
4.    Change the colour scheme for DeepSkyStacker Live to make it more "night vision" friendly.
5.    Recognise and use GAIN values in FITS file from CMOS/CCD cameras in a manner similar to how ISO is handled for matching darks, lights etc.. Please note this is not the same as EGAIN (e-/ADU). It refers to the camera's scaling of EGAIN.
6.    Update help files. My thanks to Estela Nuñez, Giovanni Benintende, Günter Heberger, José Mozart Fusco, Luc Coiffier, Михаил Тимофеев (Mickle Timofeyev), and Premysl Lukavský for their immense help with all the translation work needed for this release. Dutch help is deferred until the next release.
7.    Issue #83: Provide the option to perform NO White Balance processing at all (requested by Ivo Jager for StarTools).
8.    Fix for issue #42 - the stacking method "Average" wasn't always reported in the recap html file.
9.    Common control library 6 now used so some cosmetic changes such as filled progress bars.
10.    Make the progress dialogs non-modal so that DeepSkyStacker can be minimised while processing.
11.    Update the DeepSkyStacker taskbar icon with a progress bar that matches the main progress bar.
12.    Saving of final TIFF file is now faster, and a number of other performance enhancements have been made.
13.    Ctrl-A will select all images in the file list (not the same as "Check All").
14.    Del key will delete an image from the file list so you don't need right click and select "Remove from list"
15.    Bug fix - if you change the type of an image from the file list "Properties" dialogue, the icon was changed, but the text wasn't.
16.    Bug fix - Settings were handled incorrectly in 4.2.3 Beta 1

Cheers
Tom
