Hi !
Let me introduce myself, This is K K Chaturvedi working as a Scinetist at
IASRI and currently doing PhD in Computer Science Depratment of University
of Delhi, India.
I am writing a research article for which I need the release history of
GNats bug tracking tool. I will also be thanksful to you, if you can
provide me the yearwise download history of the GNats by the users. I am
looking for the information of yearwise number of downloads as well as
yearwise releases of the tool. Your site/resource will be duly
acknowledged in the article.
