Version history:


- Fixed a crash with very large DNG files, and potentially improved stability with large files in general

- Fixed a bug with collapsing My Computer / This PC in the file browser



- Fixed the missing highlight warning button in version 2.26

- Fixed wrong colours with some cameras in the 2.26 version (eg. Canon EOS 5D III)

- Fixed a missing dll in the new 64-bit installer, which prevented the program from starting on some older CPU-s, like many of the early Core 2 Duo-s

- Program automatically maximises its window on start if it was maximised the last time it was closed

- A minor performance optimisation



- Now a 64 bit program

- Fixed using arbitrary rotation resulting in zero sized TIFF files if set to 16 bit/channel

- Much better white balancing and more realistic colours under in-door lighting

- Increased colour temperature slider range

- Fixed most user interface issues with Windows text DPI settings other than 100% (main UI elements are not scaled now - proper high-DPI support is coming soon)

- Preferences, save options, and crop tool window now scaled according to Windows DPI setting

- Set one of the fonts slightly larger to make it more readable on high resolution displays

- Made the vertical slider automatically change size when the mouse is over it

- Vertical slider auto hides if all controls fit on the screen

- Fixed shifted edit box issue with the slider values on Windows 10

- Added support for Canon EOS 6D Mark II

- Better calibration for the Canon EOS 5D III

- Some minor bug fixes



- Support has been added for:

Canon EOS 77D, 800D, M5, M6, M100, G9 X, G9 X II

Nikon D750, D3400, D5600, D7500,

Leica TL, TL2, CL, M10,

Olympus E-PL8, E-PL9, E-M1 II, TG-4

Panasonic Lumix G8, G9, GX8, GX9, G80, G81, G85, GH4, GH5,

Pentax K3 II, KS2, Q7, QS1

Sony α7, α7 III, α9, α3000, α3500, α5000, α5100, α6000, α6300, QX1, RX0, RX10 II, RX10 III, RX10 IV, RX100 II, RX100 III, RX100 IV, RX100 VI

- Support has been removed for Samsung NX10, NX11, and NX20

- Fixed stripe on the edge of the image for many camera models with the Scarab demosaic method (this was only visible zoomed in)

- Fixed black level/calibration issues (reddish shadows) the software had with Leica and Panasonic cameras, and on many Canon, Nikon, Olympus, and Pentax models.

- Improved image quality with the Hybrid demosaic method

- Reduced purple glow around highlights with the Scarab and hybrid demosaic methods

- Fixed some artifacts that would occasionally appear in highlights with the Scarab demosaic and hybrid methods

- Fixed a bug, which resulted in poor detail rendition with the default Scarab demosaic algorithm on many cameras (Canon and Sony not affected)

- Improved highlight recovery

- Fixed a crash bug that occurred with a few raw files from some camera models

- Fixed support for the Olympus E-M10 Mark II

- Created workaround for buggy behaviour when editing a slider value while the crop tool is open

- Fixed a small memory leak (each time when editing a slider value)

- Delete on keyboard now deletes current image (ie. keyboard short-cut for delete)

- Changed the default black level, saturation, vibrance, and the tone curve for more natural colours and better contrast.

- Better resilience to damaged raw files

- Fixed white level (occasional purple or overly clamped highlights) on: Canon 80D, Leica D-Lux 5, Nikon D200, Panasonic FZ330, DMC-G1, G5, D80, Sony A65, and some variants of the A55

- Performance optimizations

- Added matching for Japanese/American names of Canon camera models to identify them: Kiss X7i (700D), REBEL T6i / X8i (750D), 8000D / Rebel T6s (760D), Kiss X70/ REBEL T5 (1200D), Kiss X80/ REBEL T6 (1300D)

- Other minor improvements



- Added support for Canon EOS 7D Mark II, 1D X Mark II, M3, M10, 80D, 100D, 750D, 760D, 1200D, and 1300D

- New thumbnails are now automatically loaded when files are added to the current directory. This allows one to already start processing the pictures while copying them from the memory card.

- Fixed a crash bug, which occurred in version 2.23 with Nikon P330, P7700, and P7800 raw files

- Corrected dark edges problem on Canon PowerShot S95.

- Fixed a memory leak, which occurred when deleting an image.

- Changed default vibrance to 0.10 and the black level back to 0.01.

- A small optimization for faster loading (and slightly increased memory consumption).

- Fixed a texture filtering problem on the right edge of the image (it didn't affect the saved image).

- Fixed a tiny imprecision with image rotation.

- The error dialog window for unsupported cameras is now always on top.

- A change in the handling of mouse capture events.

- Much better resilience to damaged raw files

- Canon EOS 1D and 1Ds III support fixed and re-added

- Canon EOS 1D II(N) support fixed and re-added

- Removed support for Canon EOS 20D (crashes in 2.23)

- Small code changes preparing for a 64 bit version
