I just made a bug release version of UFRaw. The fixed bug are:
* Recognize Sony's *.arw file type.
* Redirect exiv2 warnings from the terminal to the log.
* Fix build for some build environments (libjpeg errors).
* Treat Minolta's Alpha and Maxxum models as the Dynax model for WB presets.
If non of these bugs effect you there is no need to upgrade,
