Apparentely, The Gimp 2.0 had been available in Debian Sid for some time already before I found out. When I did (thanks to Michiel) I apt-getted it at once and started to play with it. I already tried to find a good article somewhere on the internet which discussed the new features in The Gimp 2.0 in depth, but couldn't find one. Better write one myself then, no?

Foreword
(Better cover myself). I'm no Gimp expert, though I've used it for quite a while. In this little article I'll discuss some of the things I found in the new Gimp, but that doesn't mean that I'm right about any of my assumptions. Some features, for instance, might already have been present in the old Gimp 1.2. Don't bust my balls if I'm wrong about something okay? Feedback is always welcome of course.
New stuff
To my disappointment, there isn't really a lot of new stuff in the Gimp 2.0. There are, however, a lot of subtle changes and improvements:
- User interface
One of the most noteworthy new things in the Gimp 2.0 is the interface. It's changed a lot since the old version but it's still recognisable. Gimp veterans will have no trouble finding the old stuff, and can be thrilled about the new user interface. Everything feels much more polished and easier. Frequently used options are moved to better reachable places and everything is just less obscure.
- Docks
Where in the old gimp you had to wrestle six or more dialogs with all kinds of options, in the new Gimp everything is dockable. Just drag and drop a dialog to a docking handler in one of the docks, and it will automatically dock there. Clicking the dashed undock handlebar will undock the window (surprise suprise!). It works great, although the number of docking handlers could have been more. Now they are only present at the top and bottom of the dock and sometimes you'll have to fiddle around a bit with the various docked dialogs in order to get them just the way you want.
- More dialogs
There are some new dialogs like a seperate color dialog (yes, I know you could already do this in the Gimp 1.2, but this still feels new somehow. At least now it's really useable). A font dialog shows all the fonts that can be picked easily. There's also a selection editor in which you can quite easily modify selections so you won't have to use the Rightclick->selection menu anymore. The navigation dialog is also quite nice, but I believe this was already present in some form or another in the old Gimp.
Remember that all these dialogs can be docked so they won't ever get in your way.
- Dialog improvements
Some dialogs had big improvements. For one, most dialogs now remember their size when you resize them and reappear at that size next time you open them.
Next to that it's now possible to save your tool option preferences so you can reload them later on.
Color dialogs now show colored previews in the slider so you'll now to what color you'll be changing if you move the sliders. It also remembers the last 20-something colors you've picked so you'll won't be needing that color droplet that much anymore.
- QuickMask
Something I've been wanting for a long time is more preferences for the QuickMask. The QuickMask is that small little rectangle in the lower left corner of an open image which, if you press it, will show you the current selection you've made as a mask. You can then proceed to use normal drawing tools on the mask to change the selection. Really neat, except for one thing: it wasn't possible to change the mask color. It would always be red. This fact rendered it useless (for me at least). It would get impossible to see the difference between mask and non-mask. (perhaps I'm a bit colorblind or something?). This however has been fixed. You can now select the color for the mask, and even set it's opacity. yay!
- Templates
A completely new feature in the Gimp are templates. You can save an image as a template and then base other images on that template. Quite a nice feature if it only saved the image and not just the dimensions of the image. All it seems to do is remember the height and width, nothing more. Perhaps I'm not using it correctly 'cause it seems like a pretty useless feature like it is now.
- Text
Text is always dynamic now. Not much else has changed. Oh yeah, the text properties are now easier settable from the tool options.
- Faster
Loading and Saving images seems somehow faster. Taking a screenshot of a 1600×1200 screen also seems faster. But that might have something to do with me upgrading the RAM in my system. (Sidenote: after about 20 minutes, things went pretty sour.. check below)
Not everthing's great.
Even though the new features are excellent, I've still got some gripes with the new Gimp. Some of these are old issues which I had hoped they would have fixed. Others are just missing in the new version while they were present in the old..
Conclusion
So.. in conclusion.. The new interface simply rocks. It can be improved here or there, but overall it's simply supurb. I expected some more new features and was a bit disappointed when there weren't many. There's still some bugs in the new gimp, but that's to be expected.
I've also got the feeling that I missed a lot of the new features. I do know that everything I used to do in the gimp proved to be no problem in the new Gimp. This fact shows that they did a really great job in improving the interface without having to alienate the old users. A job well done, Gimp programmers. Kudo's to you!
/me is a happy little gimper.
