Camera Bits has posted the first public beta of the next release of its pro photo browser Photo Mechanic. Version 4.6.9 public beta 1 improves support for photos taken with the Canon EOS 5D Mark III, fixes a handful of bugs and more. Once out of beta, v4.6.9 is expected to be the last v4.x iteration of Photo Mechanic before the company ushers in Photo Mechanic 5.

Download links are in a Camera Bits forum post. A complete list of the changes in v4.6.9 public beta 1 is below.

Version 4.6.9
* Added support for the Exif 2.3 Serial Number tag for newer cameras that actually write this field (i.e. not guaranteed to be there even if camera is writing Exif 2.3).
* Improved support for the Canon EOS 5D Mark III.
* Added support for RAW ORF files from the Olympus E-PL3 and E-PM1.
* Fixed various memory leaks that could eventually cause a memory allocation failure for users editing or ingesting a very large number of photos.
* Fixed an issue when sequentially ingesting cards with filenames that overlap. This can happen when the user sets their camera preference to start filer numbering at 0001 for each card.
* Fixed a problem updating XMP in LZW-compress TIFF files saved by Capture NX2.
* Added a workaround for viewing NEF files processed by Nikon Image Transfer that are not written properly.
* Fixed a problem with adding GPS coordinates to Canon 30D JPEG files.
* The Exif Digitized Date/Time tag is now updated when using the Adjust Capture Times command.
* Ingest now ignores Fuji FFDB.DAT files, Canon Comstate files, and EYEFI folders.
* Lossless JPEG rotation now uses default DPI setting instead of Save As DPI setting.
* Fixed a problem with PM SlideShow playback becoming unresponsive with a large number of files.
