Version 8.0.2 (10 September 2008)
Fix: PowerPC Mac only: transparent 'holes' in generated panoramas

Version 8.0.1 (9 September 2008)
Faster stitching and blending on PowerPC Macs
Fix: occasional crash

Version 8.0 (2 September 2008)
Redesigned memory management, resulting in faster stitching
The 64 bit version (PTGui Pro for Windows only) now efficiently uses all RAM on 64 bit Windows systems, resulting in faster stitching of large panoramas
Output crop feature: drag the edges of the panorama in the Panorama Editor to crop
New blender: faster, requires less memory and gives better blending quality
Panorama Editor now shows blended panorama
Source images are automatically reloaded if the original file on disk is modified
Control point generator is more sensitive
Improved blending and exposure fusion at nadir and zenith of 360 x 180 degree spherical panoramas
GPS support: If the EXIF data of one or more source images contain GPS coordinates, the coordinates are averaged and copied to the output (currently works for JPEG and TIFF only)
Exchanging projects between the Mac and Windows versions of PTGui is now supported by replacing the path separator in file names (slash or backslash)
Ability to output 'flattened' .psb and .psd files, with only a background layer. This can be selected by pressing the 'Settings' button in the Create Panorama tab. Please note that Photoshop does not support transparency in flattened images.
Options/Preferences: 'Show Exif dialog' option removed (obsoleted by the 'Automatic' checkbox in Project Assistant)
Create Panorama button in Project Assistant becomes enabled after applying a template, even if there are no control points
After running Align Images in the Project Assistant, the panorama size is set to the optimum size, but limited to 20 megapixels (was 4 megapixels)
When optimizing using PTOptimizer, control point errors are now calculated at the 'optimum size' of the panorama. Thus the reported quality of optimization no longer depends on the configured panorama size.
PTGui for Windows can now be forced to be running on 1 processor/core only (so called 'processor affinity'). This is a workaround for a Hyperthreading bug in certain older Pentium D processors.
Added sensor size data of new cameras
Fix: optimizer bug causing failed optimization if the project has images with a pitch close to +90 or -90 degrees
Fix: if the size or aspect ratio of a source image was changed after adding it to a PTGui project, PTGui would ignore the change and still use the former size of the image, resulting in incorrect stitching.
Fix: Mac: PTGui could hang indefinately while waiting for enblend to finish
Fix: Menu item "Generate Control Points For Images .. and .." would sometimes show the wrong image numbers
Fix: For line-type control points, selecting a control point in the control point list would not always scroll the control point into view in the Control Points tab
Fix: PTGui Pro would refuse to use the Panotools optimizer if one of the images had viewpoint correction enabled, even if 'use control points of' for all viewpoint corrected images was disabled.
Fix: PTGui Pro failed to load certain .hdr files
Fix: Mac: 'Delete all/worst control points' was sometimes incorrectly greyed out
Fix: Occasional crashes
Fix: Mac: loading a corrupt or incompatible jpeg file would cause PTGui to crash
Fix: Reset button in Exposure/HDR did not reset the Exposure Offset
Fix: 32 bit tiff source images were degraded to 8 bit
