Intel to Discontinue First-Generation Thunderbolt 3 Controllers
 

Intel this week announced plans to discontinue its first generation Thunderbolt 3 controllers it launched in 2015, coming as a consequence of an industry transition from leaded to lead-free components. The company has had newer controllers in its fleet for quite a while, so it should not be a problem for PC makers to switch to them as they migrate to newer Intel platforms, such as Cannon Lake or Coffee Lake.
