OK, a few details (from rc3, ex Gutsy)...
- Selection tools have been improved out of sight. Well, actually, they&rquo;ve been improved into sight in some cases. You get heads-up display of the options, & the rectangular selection allows you to dynamically add & alter rounded corners. Slight, but nifty new feature.
- Foreground Selection now has another method available: paint on an object within the general selection area & GIMP will select the whole object. You can re-paint instantly if the clues you gave turned out oddly.
- Alignment of objects now includes layers, paths & guides; aligned on an object, the selection or the whole image.
- New menu entries make colour management simpler.
- More file formats: PS’s ABR brushes; more EXIF stuff for JPEGs; clipping paths in TIFFs; deeper bitmaps & Alpha support in BMPs; PSDs get layer masks; more icon types can be read & saved to.
- One-keystroke full-screen toggle.
- Colour profiles.
- Much smarter Crop tool.
- Simpler, clearer Print page.
- Nifty new RedEye removal tools.
- Cloning with a perspective outcome.
- Lens distortion (barrel, vignetting) correction.
- Sticky JPEG quality settings.
- Plugins have been turbocharged, & can appear in any menu. Some (such as SpeedBlur) have had useful new modes added.
- A whole plethora of new Scripts were added.
- The Scheme interpreter has been improved immensely. It can handle UTF8 charsets, for example, & has regexps & other useful new parts.
- & so on...
I said that it added up to a lot; there’s much more I could cover, but that looks like a reasonable dose already.
