Version 2.00 (February 23, 2006)
Because of ExtGraph Project, it was supposed here we don't have a major update for SimpleGraph. However, ExtGraph Project is quiet for a long time.
Anyway, To improve performance and functionality of the control, most part of the code is written again. Because of that,
If you are using your own modified version of the control, or if you have derived your own graph object, you may need to rewrite your code. Otherwise, You may need to do some small changes. The good thing is that the old saved graph files are backward compatible with the new version. For the complete list of changes, please see the readme file. |
