LibRaw 0.7.0-Alpha4 is out. In this version we focused on new features, introduced in Alpha3:

• It is possible to get RAW data without tone-curve applied for all relevant bayer-sensor cameras. This mode supported for Nikon compressed NEFs, some Kodak cameras, all cameras with 8-bit RAW (including Sony A700/A900 cRAW), PhaseOne backs.
• unprocessed_raw sample application supports 'no tone curve' mode (use -N command-line switch).
• Non-rotated Fuji SuperCCD extraction is supported for DNG format.
• Fresh dcraw imported.

See Changelog for more detailed explanation.

This version available for download at usual place.
