#192 the async_nats crate has been merged into the main nats crate, under the `asynk` module name. - #192 the `jetstream::IntervalTree` type has been made private in anticipation of built-in FIFO (ordered) message processing functionality built on top of different internal structures. # 0.10.1 ## Improvements -

#177 Add `request_timeout` support for async-nats # 0.9.14 ## New Features - #173 `Options::with_static_credentials` adds support for static credential files for use in environments where they are injected into the process by means other than an on-disk file. - #174 `IntervalTree` now has the methods `min`, `max`, and `gaps` for getting the minimum, maximum, and non-contiguous gaps for the tracked intervals, for use in situations where users may want to implement their own deduplication strategies. # 0.9.13 ## Bug Fixes -

#164 `Consumer::process_timeout` properly times out from all branches. - #164 `Consumer::pull_opt` now properly checks the `Consumer.deliver_subject`. # 0.9.8 ## Bug Fixes - #161 When attempting to send a message with headers to a server that does not support headers, an error is now properly returned instead of silently dropping the message. # 0.9.7 ## Improvements - Improved error log output and avoid panicking when problems are encountered while parsing the JetStream reply subject. # 0.9.6 ## New Features - JetStream consumers are now better supported through the `Consumer::process*` methods, which also perform message deduplication backed by an interval tree. # 0.9.5 ## New Features - JetStream consumer and message acknowledgement is now supported via the `jetstream` feature. # 0.9.4 ## Bug Fixes - #150 fixed a bug with no_echo. # 0.9.3 ## Improvements - #141 use TCP_NODELAY on the connection to the server. -

Add `Options::client_cert()`. # 0.8.2 ## Bug Fixes - Flush outstanding messages when `Connection` is dropped. - Call callbacks configured by `Options`. - Shutdown only when the last `Connection` is dropped. # 0.8.1 ## Improvements - Remove `async-dup` dependency. - Update dependencies, notably `nkeys` to v0.0.11. ## Bug Fixes - Fix a bug due to which TLS authentication was not working. - Shutdown the client thread when `Connection` is dropped. # 0.8.0 ## New Features - Add `asynk::Message::respond()`. - Add `Options::with_nkey()`. ## Improvements - Update the `smol` dependency. ## Breaking Changes - Remove `crossbeam-channel` from the public API. # 0.7.4 ## Improvements * Remove the `MutexGuard` held across await points inside `cleanup_subscriptions()` to allow futures returned by async methods to implement `Send`. # 0.7.3 ## New Features * Expose the `asynk` module with the async client API. # 0.7.2 ## Bug Fixes * Implement `Subscription::close` and `Subscription::unsubscribe` correctly, which would previously do nothing. # 0.7.1 ## Bug Fixes * Fix a deadlock in `Subscription` when concurrently receiving the next message and draining. ## Misc * Add `--auth-token` flag to the `nats-box` example. # 0.7.0 ## New Features * Support has been added for NATS Headers via the `Connection::publish_with_reply_or_headers` method. ## Breaking Changes * The underlying TLS implementation has been switched from native-tls to rustls. The previously exported TLS functionality has been removed, and now you can supply certificates with the `Options::add_root_certificate` method. # 0.6.0 ## New Features * An experimental async `Connection` is now available to adventurous explorers by calling `Options::connect_async`. ## Breaking Changes * `ConnectionOptions` has been renamed `Options`. * The minimum supported Rust version (MSRV) is now 1.40.0. # 0.5.0 ## Breaking Changes * #60 `ConnectionOptions` construction has been simplified, and the `with_user_pass`, `with_token`, and `with_credentials` methods have been changed to being constructors for the type, rather than producing intermediate states. # 0.4.0 ## New Features * #57 The `drain` method has been added to the `Connection` and `Subscription` structs. ## Breaking Changes * #36 `Connection::close` is now infallible and has no return value * #36 The redundant `Subscription::close` has been removed. The same functionality exists in `Subscription::unsubscribe`. * bumped the MSRV to 1.39.0 in anticipation of possible async support. # 0.3.2 ## Misc * The minimum supported Rust version (MSRV) is now made explicit, and lowered to version 1.37.0 from 1.42.0. Crate version 0.3.1 has been yanked due to it having silently broken older Rust versions than 1.42.0. # 0.3.1 ## New Features * #19 TLS support has been added. # 0.3 ## New Features * #16 Implement reconnection logic. * #16 Buffer outbound data when in a disconnected state. * #16 Learn about new servers using the received INFO block. * #16 Callback functions may be provided via the new `Options::set_disconnect_callback` and `Options::set_reconnect_callback` which will be executed when the connection to a server has been terminated or when a new connection has been established afterward. ## Breaking Changes * #11 `Connection::new` has been renamed `Options::new`. * #13 The various iterators have been replaced with concrete implementations: `Iter`, `IntoIter`, `TimeoutIter` which ensure that the backing `Subscription` is not closed while they are in use.
