amqp-0.22.2: changelog.md

### Version 0.22.2

* replace `connection` dependency with `crypton-connection`

### Version 0.22.1

* fix a potential deadlock in `closeConnection`

### Version 0.22.0

* `closeChannel` now uses a `ChannelClosedException` to kill the channel-thread instead of `ThreadKilled`. This fixes a bug in 0.21.0 that led to errors being printed on the screen when `closeChannel` was called.

### Version 0.21.0

* added method `isNormalChannelClose`
* Channels that have no explicit exception handlers (added using `addChannelExceptionHandler`) will now print all exceptions to `stderr`, even if those are not of type `ChannelClosedException`. This is an uncommon situation, so it should not have an observable effect for most users.

### Version 0.20.0

* `fromURI` now activates TLS if the URI starts with `ampqs://`. Previously it only changed the port, without activating TLS.
* `fromURI` now supports multi-broker URIs in the form of `amqp://user:pass@host-1:port-2,host-2:port-2/vhost`

### Version 0.19.1

* add `nackMsg` and `nackEnv` methods

### Version 0.19.0

* change `FVString` to be binary instead of UTF-8 encoded

### Version 0.18.3

* respond to `channel.close` messages from the server with `channel.close_ok`

### Version 0.18.2

* support `connection` 0.3 and drop support for `network` < 2.6

### Version 0.18.1

* new function `addConnectionBlockedHandler` to be notified when the connection is blocked (due to the server being resource-constrained)

### Version 0.18.0

* `ConnectionClosedException` and `ChannelClosedException` now specify whether the close was normal (user-initiated) or abnormal (caused by an AMQP exception)
* channels that are abnormally closed and have no exception handler (set using `addChannelExceptionHandler`) will now print the error to `stderr`
* new function `getServerProperties` to get the RabbitMQ server-properties
* `consumeMsgs'` now allows setting a consumer-cancellation-callback

### Version 0.17.0

* When the server asynchronously closed a channel, this was (erroneously) internally represented as a `ConnectionClosedException`. It is now represented as a `ChannelClosedException`. This could affect you if you explicitly match on `ConnectionClosedException` or `ChannelClosedException` in your code, for example when using `addChannelExceptionHandler`.

### Version 0.16.0

* new `coName` field in `ConnectionOpts` to specify a custom name that will be displayed in the RabbitMQ web interface

### Version 0.15.1

* export the `AckType` data-type and constructors

### Version 0.15.0

* The way channels are closed internally was changed. This may affect you if you have installed an exception handler inside the callback passed to `consumeMsgs`. Specifically, the exceptions used internally to close channels are now wrapped inside `ChanThreadKilledException`. You should make sure to re-throw this exception if you did catch it.

### Version 0.14.1

* show all exceptions if no host can be connected to

### Version 0.14.0

* publishMsg now returns the message sequence-number
* new `TLSCustom` field in `TLSSettings`

* add (Read, Ord, Eq, Show) instances for most data-types

### Version 0.4.1

### Version 0.4

* Data.Text is now used instead of Strings. Using the _OverloadedStrings_ extension will make upgrading easier
* the field-types in Network.AMQP.Types should now be more compatible with RabbitMQ
* hostnames passed to openConnection will now be resolved
* basic QoS support
* exceptions thrown in a callback will not erroneously close the channel anymore
