I want to program in D, but I am not sure if I should go with Version 1.0 or with Version 2.0. What would you recommend? Some more specific questions: Is there a list of the language changes from 1.0 to 2.0? Are there any plans for a 2.0 gdc (the GNU compiler) frontend?

If you want something to work without code modification 1.0 would be the way to go. For cutting-edge features (see below) go with 2.0, but be aware that this comes at the cost of possibly breaking backwards compatibility in newer versions.Some more specific questions: Is there a list of the language changes from 1.0 to 2.0?Currently it's mostly stuff to do with final/const/invariant and the fact that class invariants now need "()" to be added to avoid an ambiguity caused by this. For a complete list (and changes in future versions, once they materialize), compare the changelogs for the 2.0 and 1.0[*] branches (http://www.digitalmars.com/d/changelog.html and http://www.digitalmars.com/d/1.0/changelog.html#new1_017, respectively). For this purpose, you can probably ignore the "Bugs Fixed" sections and focus on "New/Changed Features". [*]: starting at 1.017Are there any plans for a 2.0 gdc (the GNU compiler) frontend?I don't know about this one. It might depend on how much work it'd be, since keeping up with Walter seems to be a lot of work already with just one branch...

In my opinion it would make sense to have a seperate list which documents the language changes from 1.0 to 2.0. ~MichaelSome more specific questions: Is there a list of the language changes from 1.0 to 2.0?Currently it's mostly stuff to do with final/const/invariant and the fact that class invariants now need "()" to be added to avoid an ambiguity caused by this.

The DMD 2.0 compiler is highly experimental, and only has the first of the new features. Only use it if you want to help contribute to the development of 2.0.
