 ## [Unreleased]
 
+# [1.2.0] - 2019-11-28
+
+[API Documentation](https://docs.rs/async-std/1.2.0/async-std)
+
+This patch includes some minor quality-of-life improvements, introduces a
+new `Stream::unzip` API, and adds verbose errors to our networking types.
+
+This means if you can't connect to a socket, you'll never have to wonder again
+*which* address it was you couldn't connect to, instead of having to go through
+the motions to debug what the address was.
+
+## Example
+
+Unzip a stream of tuples into two collections:
+
+```rust
+use async_std::prelude::*;
+use async_std::stream;
+
+let s  = stream::from_iter(vec![(1,2), (3,4)]);
+
+let (left, right): (Vec<_>, Vec<_>) = s.unzip().await;
+
+assert_eq!(left, [1, 3]);
+assert_eq!(right, [2, 4]);
+```
+
+## Added
+
+- Added `Stream::unzip` as "unstable".
+- Added verbose errors to the networking types.
+
+## Changed
+
+- Enabled CI on master branch.
+
+## Fixed
+
+- Fixed the docs and `Debug` output of `BufWriter`.
