I’m trying to add a version history of BeOS to the Wikipedia article, however, resources are lacking (even through Google). Then again, I find the whole Wikipedia article on BeOS to be lacking, especially in the overall features of BeOS.
Anyone have a list of versions and dates (and maybe the significance of each version) to share? I’ll be sure to add it immediately to the article.
There is an history in the French page, mostly based on my webpage.
You may use Babelfish to have a rough translation
