 # [1.8.0] - 2020-12-04
 
 This patch introduces `async_std::channel`, a new submodule for our async channels implementation. `channels` have been one of async-std's most requested features, and have existed as "unstable" for the past year. We've been cautious about stabilizing channels, and this caution turned out to be warranted: we realized our channels could hang indefinitely under certain circumstances, and people ended up expressing a need for unbounded channels.
