New version of UFRaw, a free Raw processing tool, is out with some important improvements, including lens distorsion fixes and new denoising feature.

Here is the list of changes:

• Official support for LensFun, a library to fix various optics distorsions, autoadjustment implemented;
• Added a despeckling/denoising algorithm to solve issues with images taken
  under very difficult lighting conditions, like deep sea diving.
  It may be useful in other situations too. Patch by Frank van Maarseveen.
• Enabled hot pixel elimination by default.
• Calculate live histogram from working color-space instead of display
  color-space. Calculate live histogram from cropped area only.
• Added auto-crop option.
• Allow up to 400% zoom.;
• Newly supported cameras (DCRaw 8.99):
  • Canon PowerShot S90
  • Canon EOS 550D / Digital Rebel T2i / Kiss Digital X4
  • Canon EOS-1D Mark IV
  • Casio EX-Z750
  • Fuji FinePix S200EXR
  • Pentax K-x
  • Samsung NX10
