Photo Mechanic version 4.6.2.2 public beta 3 is available for download immediately, for either Mac OS X users or Windows users. Photo Mechanic is compatible with Microsoft's Windows 7, Vista, or XP Service Pack 1 - 3, as well as Apple's Mac OS X 10.4.11, or 10.5.x operating systems.

Courtesy of Camera Bits, the full list of changes in the new version is as follows:

Both platforms:

• Changed how QuickTime files are opened to prevent QuickTime from showing UI dialogs/windows on our background threads which would cause Photo Mechanic to crash.

• FTP and SFTP uploader templates now handle destination folder paths with {variables} in such a way that attached files (e.g. XMP and WAV sidecar files) will end up in the same destination folder as the photo they belong to. Also, using variables like {folderpath} now return the path to the original image where it resides.

• Added preference to control whether Structured Keywords will be written only to the lr:hierarchicalSubject field or if they will be written to both the hierarchicalSubject field and dc:subject field when updating XMP. All keywords, flat or structured will be always written to the IPTC keywords field since there is no other place to put them in IPTC.

• Improved handling of low memory conditions.

Mac only:

• Ingest now uses OS-supplied copy facility to copy images from the card. This was done in an attempt to speed up Ingests on Mac OS X 10.6.x.

• Copy/Move of files via drag and drop now handles case where multiple files with the same name are copied/moved to the drop destination folder. Files that arrive and have a file with the same name at the destination are now renamed to allow them to exist at the destination folder.

Windows only:

• Fixed a hanging bug in the Import GPS Coordinates command.
