Customers who've purchased Photo Mechanic since February 2009 can upgrade for free. The full program costs $160 for new users, or $100 for users upgrading from an older version of Photo Mechanic 4.x. If the physical CD isn't required, there's a $10 discount available; International users needing the CD will have to pay an extra $15 for shipping.
Courtesy of Camera Bits, the full list of changes in the new version is as follows:
Improved support for the Canon EOS-1D Mark IV model.
Fixed problems with soft crops in RAW files not showing correctly, primarily with DNG files that have a cropped preview generated by DNG Converter and Nikon NEF files saved by Capture NX 2 with a rotation or crop applied.
RAW files with existing Photo Mechanic end-of-file preferences will be updated as necessary regardless of setting to "Allow RAW (non-DNG) files to be modified" (so that the existing data doesn't become "stale").
Fixed a bug in the Save As dialog where the root save folder path wasn't being saved and restored properly in the preferences.
(Win) Tag/Rating/Color Class advance to next photo in Preview window now works properly and updates the info text and histogram.
(Win) Fixed Arrangements issue when reusing Contact Sheet tabs.
(Mac) Loupe tool now works for RAW files that contain no embedded JPEG preview as long as ImageIO supports them.
- (Mac) Fixed Tooltip "ghosting" issue.
