These are the major user-visible changes in 1.0:
- A greeter dialog was added, similar to the ones used by cgoban or gGo.
- There is now a "Learn Go" button that brings up beginner tutorials in a slideshow view.
- Engine configuration in the preferences is a little more friendly.
- Edit mode works differently. Depending on the situation, an edited position can be appended to or inserted before the current node, or replace a previous edit.
- The board window now has menu items for undo/redo.
- When playing on IGS, the comments box now allows chatting even after a match has completed, making it unnecessary to find the opponent's talk tab.
- Corrected a bug when parsing nmatch preferences on IGS.
