In a discussion on David Green’s blog Chris Aniszczyk suggested that EGit might be interested in a contribution of the GitHub Mylyn connector originally developed by Christian Trutz.
Both Christian and David (who added new features to the connector at) expressed their interest in contributing their work to EGit (see also).
The work on Mylyn Github connector continues under umbrella of EGit and this project will be hibernated.
