**Full Changelog**: https://github.com/nats-io/nats.rs/compare/async-nats/v0.34.0...async-nats/v0.35.0


# 0.34.0

## Overview

This release introduces performance improvements (thanks to poll_recv_many #1189), improves resilience of
ordered consumers by recreating them in more cases while having less server calls. It also adds some new features.

## Breaking Changes
Breaking changes are minor, however, all are worth mentioning.

* Don't expose BoxFuture in public API by @oscarwcl in https://github.com/nats-io/nats.rs/pull/1167

This change simplifies lifetimes of Boxed Futures, by making them static. It should not affect most users,
and if it does, removal of the lifetime should be a quick fix.

* Add check for max payload size when publishing messages by @Jarema in https://github.com/nats-io/nats.rs/pull/1211

The client was not checking if the message payload size was not exceeding the limits of the server it is connected to.
While doing the fix, the error returned was changed into one consistent with others: a struct with enum of possible
error variants under `kind()` method, of which one is `MaxPayloadExceeded`. This should not break users,
as before there was no enum in the first place, but it is a breaking change.

* Add stream name check to all stream management methods by @Jarema in https://github.com/nats-io/nats.rs/pull/1214

It added new enum variant to Consumer and Stream error kinds. Breaking for those who match those errors in exhaustive manner.

* Remove clone in message split method by @AbstractiveNord in https://github.com/nats-io/nats.rs/pull/1172

This changes to be a `mut self` from `self` while removing unnecessary clone.

# 0.33.0
## Overview

This release introduces last planned breaking changes and stabilizes the async API.

### Subject in publish methods
The biggest change is how subjects are handled. Until now, publish was of type `String`:
```rust
client.publish("subject".to_string(), "data".into()).await?;
```
This was easy to understand and reason about, but had two downsides:
1. It was always allocating
2. It was cumbersome for codebases working with `&'static str`

The signature has been change into:
```rust
// Signature
async fn publish(subject: impl ToSubject, payload: Bytes)
// Usage
client.publish("subject", "data".into()).await?;
```
This is not only more concise, but also allows avoiding allocations when subject is `static`,
or when it is `Subject` type that can be cheaply cloned leveraging memory optimized `bytes::Bytes` mechanism under the hood.

### Service API improvements
Beyond that, there were a lot of improvements to Service API to address cross-language compatibility issues.
All structures are now tested against common cross-language json schemas.
Thanks @jadamcrain for all the feedback, issues nad PRs related to Service API!

### Docs improvements
Despite every method having documentation with examples, we were aware that sometimes its hard to navigate the docs to find what someone is looking for.
This was addressed by adding module-level docs.

## Added
* Add subject type by @caspervonb in https://github.com/nats-io/nats.rs/pull/952 & @Jarema in  https://github.com/nats-io/nats.rs/pull/1147

**Full Changelog**: https://github.com/nats-io/nats.rs/compare/async-nats/v0.30.1...async-nats/v0.32.0

# 0.31.0
This release focuses on improvements of heartbeats in JetStream Consumers.

Heartbeats are a tool that tells the user if the given consumer is healthy but does not get any messages or if the reason for no message is an actual problem.
However, if the user was not polling the `Stream` future for the next messages for a long time (because it was slowly processing messages), that could trigger idle heartbeats, as the library could not see the heartbeat messages without messages being polled.

This release fixes it by starting the idle heartbeat timer only after Stream future is polled (which usually means calling `messages.next().await`).

## What's Changed
* Fix unwrap from `HeaderName::from_str` call by @caspervonb in https://github.com/nats-io/nats.rs/pull/1032

**Full Changelog**: https://github.com/nats-io/nats.rs/compare/async-nats/v0.29.0...async-nats/v0.30.0

# 0.29.0
## Overview

This release focuses on preparing for the 1.0.0 release.

The main highlight is Core NATS concrete errors.
There are also security improvements (@paolobarbolini thanks for your help!) and JetStream API improvements.

## Concrete Errors

New errors returned by Core NATS methods are not boxed anymore.
They themselves are not enums, but follow more flexible approach of `std::io::Error` and expose `kind()` method to get the enum.
All enums implement `PartialEq` for more straightforward assertions.

## Added
* Add support for stream subject transform by @n1ghtmare in https://github.com/nats-io/nats.rs/pull/867
* Add retaining server list order option by @Jarema in https://github.com/nats-io/nats.rs/pull/890

## Fixed

* Fix reconnect burst on auth failure by @Jarema in https://github.com/nats-io/nats.rs/pull/890

## Changed

* @marcusirgens made their first contribution in https://github.com/nats-io/nats.rs/pull/864
* @paolobarbolini made their first contribution in https://github.com/nats-io/nats.rs/pull/872

Once again, thanks @abalmos & @NorbertBodziony for helping out with replicating the issues around fetch.
Also big thanks @paolobarbolini for the very detailed report and reproduction for TLS issue and @n1ghtmare for debugging Windows related issues.

Your contributions are invaluable to the NATS ecosystem.

**Full Changelog**: https://github.com/nats-io/nats.rs/compare/async-nats/v0.28.0...async-nats/v0.29.0

# 0.28.0
## Overview
This release prepares the client for 2.10.0 server release and adds some fixes and improvements.

To use the new features before the server 2.10.0 release, enable `server_2_10` feature.

## Breaking Changes
### To enable NAK with backoff, `AckKind::NAK` enum variant was changed

What was before:
```rust
AckKind::Nak
```

now is:
```rust
AckKind::Nak(Option<std::time::Duration>)
```
Which means a standard NAK example
```rust
let message = messages.next().await?;
message.ack_kind(AckKind::Nak).await?;
```
Now should be used like this
```rust
let message = messages.next().await?;
message.ack_kind(AckKind::Nak(None)).await?;
```
or with custom NAK
```rust
message.ack_kind(AckKind::Nak(Some(std::time::Duration::from_secs(10))).await?;
```
### Consumer info cluster field is now `Option`
This field is provided only in clustered mode, so it's now properly inline with that.

### Consumer `idle heartbeat` error does not terminate iterator
This change does not require any action from the users who want to continue using client
as they do now, but those who would like to try continuing working with consumer,
even if it returned `idle heartbeats`, now they can.

**Full Changelog**: https://github.com/nats-io/nats.rs/compare/async-nats/v0.22.1...async-nats/v0.23.0

# 0.22.1
## Overview
A patch release, including early feedback to 0.22.0.

## Breaking Changes

Unfortunately, last release included a typo in `retry_on_initial_release`.
This patch fixes it.
We decided to make a normal patch release without yanking as we're pre 1.0.0 verison.
To avoid similar situations in the future, spellecheck lint will be added before next release.

## Changed
* Flush on publish ack await by @Jarema in https://github.com/nats-io/nats.rs/pull/708
## Fixed
* Fix typo in retry_on_initial_connect by @Jarema in https://github.com/nats-io/nats.rs/pull/713
## Added
* Setup cargo deny to check licenses by @corbinu in https://github.com/nats-io/nats.rs/pull/703

# 0.22.0
## Overview
This release introduces a number of changes and two breaking changes:

### JetStream publish
Used to return ack:
```rust
let ack = jetstream.publish().await.unwrap();
```
But while adding publish that does not wait for acknowledgment before returning,
we realized that we can leverage [IntoFuture](https://doc.rust-lang.org/std/future/trait.IntoFuture.html), so the new API is:
```rust
// This publishes the message, but do not wait until ack is received.
let future_ack = jetstream.publish().await.unwrap();
// to receive the acknowledge, `await()` the returned value:
let ack = future_ack.await().unwrap();
```
### Event logging
After adding initial retry on connect option, `Event::Reconnect` didn't make much sense.
Hence it was renamed to `Event::Connected`, which describes the current state without implications about the previous one.
For consistency, `Event::Disconnect` was renamed to `Event::Disconnected`.

## Breaking changes
* Defer publish acknowledgments by @Jarema in https://github.com/nats-io/nats.rs/pull/644

# 0.18.0
## Overview
This release focuses on fixes and improvements, with addition of ordered Push Consumer.

# 0.17.0
## Overview
This release focuses on two main things:
* Refactor of JetStream API
* Fix of slow connect (thanks @brooksmtownsend for reporting this!)

The changes in JetStream API make usage of builder more intuitive and seamless.
Before, you had to call
```rust
// before changes
let messages = consumer.stream().await?;
// or use a shortcut
let messages = consumer.messages().await?;

// after changes
let messages = consumer.stream().messages().await?;
// or with options
let messages = consumer.stream().max_bytes_per_bytes(1024).messages().await?;
```
