Both PhotoTune 3.0.1 and PhotoTools 2.5.1 improve compatibility with ATI video cards on Windows PCs, although the onOne blog notes that memory errors are still possible with PhotoTune under 32-bit Windows). PhotoTune 3.0.1 also has improved stability, and better memory handling, leading to a reduced memory footprint. Mask Pro 4.1.7 also has improved performance on Windows machines, as well as fixing an error with cursor tracking, and an erroneous out of memory error. Performance with large brushes has also been improved, and a Mac OS X specific issue with the Mask Pro window moving unexpectedly has been corrected. onOne Suite 5.0.1 incorporates all of these changes, bringing its component parts up to their latest versions. Finally, onOne Photo Essentials 3.0.1 corrects an error with cursor tracking in Cut It Out, improves Windows ATI graphics card compatibility for Make It Better and Make It Cool, and reduces the memory footprint while increasing stability for Make It Better.

onOne Plug-In Suite 5 consists of Genuine Fractals 6 for resizing images, Mask Pro 4 for removing backgrounds, PhotoTune 3 for color correction, FocalPoint 2 for creating depth of field / focus effects, PhotoTools 2.5 offering a range of filter effects, and PhotoFrame 4.5 to add frames to images. onOne Plug-In Suite 5.0.1 requires the existing 5.0 version to be installed prior to updating, and is available from onOne Software's website for both Mac and Windows platforms. Plug-In Suite 5 costs about $600 for the full version, or $200 for an upgrade version which requires that the user own Plug-In Suite 1, 2, 3 or 4.x. onOne Photo Essentials 3 costs $70 for the full version, or $50 for the upgrade version.
