Technic as a single player pack no longer has a point. With the changes made to minecraft, there is no longer a need for a line between multi and single. As such, the name "Technic" has been repurposed as to cover the entire brand of Technic products, and the functioning current modpacks, in chronological order is Tekkit Classic, Tekkit Lite, and the newest Tekkit, which is the most up to date. Anything 'missing' has been intentionally removed, as it has either not been updated at the same rate as other mods, or the team felt it wasn't fitting the theme.
