v1.4.0 Changes
December 20, 2019
📚 API Documentation

⏱ This patch adds Future::timeout, providing a method counterpart to the 🛠 future::timeout free function. And includes several bug fixes around missing APIs. Notably we're not shipping our new executor yet, first announced on our blog.

Examples
```
use async_std::prelude::*;
use async_std::future;
use std::time::Duration;

let fut = future::pending::<()>(); // This future will never resolve.
let res = fut.timeout(Duration::from_millis(100)).await;
assert!(res.is_err()); // The future timed out, returning an err.
```
➕ Added
- ➕ Added Future::timeout as "unstable" (#600)
🛠 Fixes
- 🛠 Fixed a doc test and enabled it on CI (#597)
- 🛠 Fixed a rendering issue with the stream submodule documentation (#621)
- Write::write_fmt's future is now correctly marked as #[must_use] (#628)
- 🛠 Fixed the missing io::Bytes export (#633)
- 🛠 Fixed the missing io::Chain export (#633)
- 🛠 Fixed the missing io::Take export (#633)
v1.3.0 Changes
December 12, 2019
📚 API Documentation

This patch introduces Stream::delay, more methods on DoubleEndedStream, and improves compile times. Stream::delay is a new API that's similar to 📄 task::sleep, but can be passed as part of as stream, rather than as a separate block. This is 👉 useful for examples, or when manually debugging race conditions.

Examples
```
let start = Instant::now();
let mut s = stream::from_iter(vec![0u8, 1]).delay(Duration::from_millis(200));

// The first time will take more than 200ms due to delay.
s.next().await;
assert!(start.elapsed().as_millis() >= 200);

// There will be no delay after the first time.
s.next().await;
assert!(start.elapsed().as_millis() <= 210);
```
➕ Added
- ➕ Added Stream::delay as "unstable" (#309)
- ➕ Added DoubleEndedStream::next_back as "unstable" (#562)
- ➕ Added DoubleEndedStream::nth_back as "unstable" (#562)
- ➕ Added DoubleEndedStream::rfind as "unstable" (#562)
- ➕ Added DoubleEndedStream::rfold as "unstable" (#562)
- ➕ Added DoubleEndedStream::try_rfold as "unstable" (#562)
- stream::Once now implements DoubleEndedStream (#562)
- stream::FromIter now implements DoubleEndedStream (#562)
🔄 Changed
- ✂ Removed our dependency on async-macros, speeding up compilation (#610)
🛠 Fixes
- 🛠 Fixed a link in the task docs (#598)
- 🛠 Fixed the UdpSocket::recv example (#603)
- 🛠 Fixed a link to task::block_on (#608)
- 🛠 Fixed an incorrect API mention in task::Builder (#612)
- 🛠 Fixed leftover mentions of futures-preview (#595)
- 🛠 Fixed a typo in the tutorial (#614)
- <TcpStream as Write>::poll_close now closes the write half of the stream (#618)
v1.2.0 Changes
November 27, 2019
📚 API Documentation

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:
```
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.
- Future::join and Future::try_join can now join futures with different output types.
🛠 Fixed
- 🛠 Fixed the docs and Debug output of BufWriter.
- 🛠 Fixed a bug in Stream::throttle that made it consume too much CPU.
v1.1.0 Changes
November 21, 2019
📚 API Documentation

⏱ This patch introduces a faster scheduler algorithm, Stream::throttle, and stabilizes task::yield_now. Additionally we're introducing several more stream APIs, bringing us to almost complete parity with the standard library.

Furthermore our path submodule now returns more context in errors. So if opening a file fails, async-std will tell you which file was failed to open, making it easier to write and debug programs.

Examples
```
let start = Instant::now();

let mut s = stream::interval(Duration::from_millis(5))
    .throttle(Duration::from_millis(10))
    .take(2);

s.next().await;
assert!(start.elapsed().as_millis() >= 5);

s.next().await;
assert!(start.elapsed().as_millis() >= 15);

s.next().await;
assert!(start.elapsed().as_millis() >= 25);
```
➕ Added
- ➕ Added Stream::throttle as "unstable".
- ➕ Added Stream::count as "unstable".
- ➕ Added Stream::max as "unstable".
- ➕ Added Stream::successors as "unstable".
- ➕ Added Stream::by_ref as "unstable".
- ➕ Added Stream::partition as "unstable".
- ➕ Added contextual errors to the path submodule.
- ➕ Added os::windows::symlink_dir as "unstable".
- ➕ Added os::windows::symlink_file as "unstable".
- Stabilized task::yield_now.
🛠 Fixes
- 👀 We now ignore seek errors when rolling back failed read calls on File.
- Fixed a bug where Stream::max_by_key was returning the wrong result.
- Fixed a bug where Stream::min_by_key was returning the wrong result.
🔄 Changed
- 🛠 Applied various fixes to the tutorial.
- 🛠 Fixed an issue with Clippy.
- ⚡️ Optimized an internal code generation macro, improving compilation speeds.
- ✂ Removed an Unpin bound from stream::Once.
- ✂ Removed various extra internal uses of pin_mut!.
- Simplified Stream::any and Stream::all's internals.
- The surf example is now enabled again.
- 👉 Tweaked some streams internals.
- ⚡️ Updated futures-timer to 2.0.0, improving compilation speed.
- ⬆️ Upgraded async-macros to 2.0.0.
- 🚤 Stream::merge now uses randomized ordering to reduce overall latency.
- ⏱ The scheduler is now more efficient by keeping a slot for the next task to run. This is similar to Go's scheduler, and Tokio's scheduler.
- 🛠 Fixed the documentation of the channel types to link back to the channel function.
v1.0.1 Changes
November 12, 2019
📚 API Documentation

🐎 We were seeing a regression in our fs performance, caused by too many 🛠 long-running tasks. This patch fixes that regression by being more proactive about closing down idle threads.

🔄 Changes
- 👌 Improved thread startup/shutdown algorithm in task::spawn_blocking.
- 🛠 Fixed a typo in the tutorial.
