 [[migration-4.1-4.2]]
 === Changes between 4.1 and 4.2
 
-For an overview of the changes in Spring Integration 4.2 since version 4.1, please see <<whats-new>>.
+Please be sure to also see the https://github.com/spring-projects/spring-integration/wiki/Spring-Integration-4.1-to-4.2-Migration-Guide[Migration Guide]
+for important changes that might affect your applications.
+Migration guides for all versions back to _2.1_ can be found on the https://github.com/spring-projects/spring-integration/wiki[Wiki].
+
+[[x4.2-new-components]]
+=== New Components
+
+[[x4.2-JMX]]
+==== Major Management/JMX Rework
+
+A new `MetricsFactory` strategy interface has been introduced.
+This, together with other changes in the JMX and management infrastructure provides much more control over management
+configuration and runtime performance.
+
+However, this has some important implications for (some) user environments.
+
+For complete details, see <<metrics-management>> and <<jmx-42-improvements>>.
+
+[[x4.2-mongodb-metadata-store]]
+==== MongoDB Metadata Store
+
+The `MongoDbMetadataStore` is now available. For more information, see <<mongodb-metadata-store>>.
+
+[[x4.2-secured-channel-annotation]]
+==== SecuredChannel Annotation
+
+The `@SecuredChannel` annotation has been introduced, replacing the deprecated `ChannelSecurityInterceptorFactoryBean`.
+For more information, see <<security>>.
+
+[[x4.2-security-context-propagation]]
+==== SecurityContext Propagation
+
+The `SecurityContextPropagationChannelInterceptor` has been
+introduced for the `SecurityContext` propagation from one message flow's Thread to another.
+For more information, see <<security>>.
+
+
+[[x4.2-file-splitter]]
+==== FileSplitter
+
+The `FileSplitter`, which splits text files into lines, was added in 4.1.2.
+It now has full support in the `int-file:` namespace; see <<file-splitter>> for more information.
+
+[[x4.2-zk]]
+==== Zookeeper Support
+
+Zookeeper support has been added to the framework to assist when running on a clustered/multi-host environment.
+
+* ZookeeperMetadataStore
+* ZookeeperLockRegistry
+* Zookeeper Leadership
+
+See <<zookeeper>> for more information.
+
+[[x4.2-barrier]]
+==== Thread Barrier
+
+A new thread `<int:barrier/>` component is available allowing a thread to be suspended until some asynchronous event
+occurs.
+
+See <<barrier>> for more information.
+
+[[x4.2-stomp]]
+==== STOMP Support
+
+STOMP support has been added to the framework as _inbound_ and _outbound_ channel adapters pair.
+See <<stomp>> for more information.
+
+[[x4.2-codec]]
+==== Codec
+A new `Codec` abstraction has been introduced, to encode/decode objects to/from `byte[]`.
+An implementation that uses Kryo is provided.
+Codec-based transformers and message converters are also provided.
+
+See <<codec>> for more information.
+
+[[x4.2-prepared-statement-setter]]
+==== Message PreparedStatement Setter
+
+A new `MessagePreparedStatementSetter` functional interface callback is available for the `JdbcMessageHandler`
+(`<int-jdbc:outbound-gateway>` and `<int-jdbc:outbound-channel-adapter>`) as an alternative to the
+`SqlParameterSourceFactory` to populate parameters on the `PreparedStatement` with the `requestMessage` context.
+
+See <<jdbc-outbound-channel-adapter>> for more information.
+
+[[x4.2-general]]
+=== General Changes
+
+[[x4.2-wire-tap]]
+==== Wire Tap
+
+As an alternative to the existing `selector` attribute, the `<wire-tap/>` now supports the `selector-expression` attribute.
+
+[[x4.2-file-changes]]
+==== File Changes
+
+See <<files>> for more information about these changes.
+
+===== Appending New Lines
+
+The `<int-file:outbound-channel-adapter>` and `<int-file:outbound-gateway>` now support an `append-new-line` attribute.
+If set to `true`, a new line is appended to the file after a message is written.
+The default attribute value is `false`.
+
+===== Ignoring Hidden Files
+
+The `ignore-hidden` attribute has been introduced for the `<int-file:inbound-channel-adapter>` to pick up or not
+the _hidden_ files from the source directory.
+It is `true` by default.
+
+===== Writing InputStream Payloads
+
+The `FileWritingMessageHandler` now also accepts `InputStream` as a valid message payload type.
+
+===== HeadDirectoryScanner
+
+The `HeadDirectoryScanner` can now be used with other `FileListFilter` s.
+
+===== Last Modified Filter
+
+The `LastModifiedFileListFilter` has been added.
+
+===== WatchService Directory Scanner
+
+The `WatchServiceDirectoryScanner` is now available.
+
+===== Persistent File List Filter Changes
+
+The `AbstractPersistentFileListFilter` has a new property `flushOnUpdate` which, when set to true, will `flush()` the
+metadata store if it implements `Flushable` (e.g. the `PropertiesPersistingMetadataStore`).
+
+[[x4.2-class-package-change]]
+==== Class Package Change
+
+The `ScatterGatherHandler` class has been moved from the `org.springframework.integration.handler` to the `org.springframework.integration.scattergather`.
+
+==== TCP Changes
+
+[[x4.2-tcp-serializers]]
+===== TCP Serializers
+
+The TCP `Serializers` no longer `flush()` the `OutputStream`; this is now done by the `TcpNxxConnection` classes.
+If you are using the serializers directly within user code, you may have to `flush()` the `OutputStream`.
+
+[[x4.2-tcp-server-exceptions]]
+===== Server Socket Exceptions
+
+`TcpConnectionServerExceptionEvent` s are now published whenever an unexpected exception occurs on a TCP server socket (also added to 4.1.3, 4.0.7).
+See <<tcp-events>> for more information.
+
+[[x4.2-tcp-server-port]]
+===== TCP Server Port
+
+If a TCP server socket factory is configured to listen on a random port, the actual port chosen by the OS can now
+be obtained using `getPort()`.
+`getServerSocketAddress()` is also available.
+
+See <<connection-factories>> for more information.
+
+[[x4.2-tcp-gw-rto]]
+===== TCP Gateway Remote Timeout
+
+The `TcpOutboundGateway` now supports `remote-timeout-expression` as an alternative to the existing `remote-timeout` attribute.
+This allows setting the timeout based on each message.
+
+Also, the `remote-timeout` no longer defaults to the same value as `reply-timeout` which has a completely different meaning.
+
+See <<tcp-ob-gateway-attributes>> for more information.
+
+[[x4.2-tcp-ssl]]
+===== TCP SSLSession Available for Header Mapping
+
+`TcpConnection` s now support `getSslSession()` to enable users to extract information from the session to add to
+message headers.
+
+See <<ip-msg-headers>> for more information.
+
+
+[[x4.2-tcp-events]]
+===== TCP Events
+
+New events are now published whenever a correlation exception occurs - for example sending a message to a
+non-existent socket.
+
+The `TcpConnectionEventListeningMessageProducer` is deprecated; use the generic event adapter instead.
+
+See <<tcp-events>> for more information.
+
+[[x4.2-inbound-channel-adapter-annotation]]
+==== @InboundChannelAdapter
+
+Previously, the `@Poller` on an inbound channel adapter defaulted the `maxMessagesPerPoll` attribute to `-1` (infinity).
+This was inconsistent with the XML configuration of `<inbound-channel-adapter/>` s, which defaults to 1.
+The annotation now defaults this attribute to 1.
+
+[[x4.2-api-changes]]
+==== API Changes
+
+`o.s.integration.util.FunctionIterator` now requires a `o.s.integration.util.Function` instead of a
+`reactor.function.Function`.
+This was done to remove an unnecessary hard dependency on Reactor.
+Any uses of this iterator will need to change the import.
+
+Of course, Reactor is still supported for functionality such as the `Promise` gateway; the dependency was removed for those users who don't need it.
+
+[[x4.2-jms-changes]]
+==== JMS Changes
+
+===== Reply Listener Lazy Initialization
+
+It is now possible to configure the reply listener in JMS outbound gateways to be initialized on-demand and stopped
+after an idle period, instead of being controlled by the gateway's lifecycle.
+
+See <<jms-outbound-gateway>> for more information.
+
+===== Conversion Errors in Message-Driven Endpoints
+
+The `error-channel` now is used for the conversion errors, which have caused a transaction rollback and message redelivery previously.
+
+See <<jms-message-driven-channel-adapter>> and <<jms-inbound-gateway>> for more information.
+
+===== Default Acknowledge Mode
+
+When using an implicitly defined `DefaultMessageListenerContainer`, the default `acknowledge` is now `transacted`.
+`transacted` is recommended when using this container, to avoid message loss.
+This default now applies to the message-driven inbound adapter and the inbound gateway, it was already the
+default for jms-backed channels.
+
+See <<jms-message-driven-channel-adapter>> and <<jms-inbound-gateway>> for more information.
+
+===== Shared Subscriptions
+
+Namespace support for shared subscriptions (JMS 2.0) has been added to message-driven endpoints and the
+`<int-jms:publish-subscribe-channel>`.
+Previously, you had to wire up listener containers as `<bean/>` s to use shared connections.
+
+See <<jms>> for more information.
+
+[[x4.2-conditional-pollers]]
+==== Conditional Pollers
+Much more flexibility is now provided for dynamic polling.
+
+See <<conditional-pollers>> for more information.
+
+[[x4.2-amqp-changes]]
+==== AMQP Changes
+
+===== Publisher Confirms
+
+The `<int-amqp:outbound-gateway>` now supports `confirm-correlation-expression` and `confirm-(n)ack-channel`
+attributes with similar purpose as for `<int-amqp:outbound-channel-adapter>`.
+
+===== Correlation Data
+
+For both the outbound channel adapter and gateway, if the correlation data is a `Message<?>`, it will be the basis
+of the message on the ack/nack channel, with the additional header(s) added.
+Previously, any correlation data (including `Message<?>`) was returned as the payload of the ack/nack message.
+
+===== The Inbound Gateway properties
+
+The `<int-amqp:inbound-gateway>` now exposes the `amqp-template` attribute to allow more control over an external bean
+for the reply `RabbitTemplate` or even provide your own `AmqpTemplate` implementation.
+In addition the `default-reply-to` is exposed to be used if request message doesn't have `replyTo` property.
+
+See <<amqp>> for more information.
+
+[[x4.2-xpath-splitter]]
+==== XPath Splitter Improvements
+
+The `XPathMessageSplitter` (`<int-xml:xpath-splitter>`) now allows the configuration of `output-properties`
+for the internal `javax.xml.transform.Transformer` and supports an `Iterator` mode (defaults to `true`) for the xpath
+evaluation `org.w3c.dom.NodeList` result.
+
+See <<xml-xpath-splitting>> for more information.
+
+[[x4.2-http-changes]]
+==== HTTP Changes
+
+===== CORS
+
+The HTTP Inbound Endpoints (`<int-http:inbound-channel-adapter>` and `<int-http:inbound-gateway>`) now allow the
+configuration of _Cross-Origin Resource Sharing (CORS)_.
+
+See <<http-cors>> for more information.
+
+===== Inbound Gateway Timeout
+
+The HTTP inbound gateway can be configured as to what status code to return when a request times out.
+The default is now `500 Internal Server Error` instead of `200 OK`.
+
+See <<http-response-statuscode>> for more information.
+
+===== Form Data
+
+Documentation is provided for when proxying `multipart/form-data` requests.
+See <<http>> for more information.
+
+[[x4.2-gw]]
+==== Gateway Changes
+
+===== Gateway Methods can Return CompletableFuture<?>
+
+When using Java 8, gateway methods can now return `CompletableFuture<?>`.
+See <<gw-completable-future>> for more information.
+
+===== MessagingGateway Annotation
+
+The request and reply timeout properties are now `String` instead of `Long` to allow configuration with property
+placeholders or SpEL. See <<messaging-gateway-annotation>>.
+
+[[x4.2-aggregator-changes]]
+==== Aggregator Changes
+
+===== Aggregator Performance
+
+This release includes some performance improvements for aggregating components (aggregator, resequencer, etc),
+by more efficiently removing messages from groups when they are released.
+New methods (`removeMessagesFromGroup`) have been added to the message store.
+Set the `removeBatchSize` property (default `100`) to adjust the number of messages deleted in each operation.
+Currently, JDBC, Redis and MongoDB message stores support this property.
+
+===== Output Message Group Processor
+
+When using a `ref` or inner bean for the aggregator, it is now possible to bind a `MessageGroupProcessor` directly.
+In addition, a `SimpleMessageGroupProcessor` is provided that simply returns the collection of messages in the group.
+When an output processor produces a collection of `Message<?>`, the aggregator releases those messages individually.
+Configuring the `SimpleMessageGroupProcessor` makes the aggregator a message barrier, were messages are held up
+until they all arrive, and are then released individually. See <<aggregator>> for more information.
+
+==== (S)FTP Changes
+
+===== Inbound channel adapters
+
+You can now specify a `remote-directory-expression` on the inbound channel adapters, to determine the directory
+at runtime.
+See <<ftp>> and <<sftp>> for more information.
+
+===== Gateway Partial Results
+
+When use FTP/SFTP outbound gateways to operate on multiple files (`mget`, `mput`), it is possible for an exception to
+occur after part of the request is completed.
+If such a condition occurs, a `PartialSuccessException` is thrown containing the partial results.
+See <<ftp-outbound-gateway>> and <<sftp-outbound-gateway>> for more information.
+
+===== Delegating Session Factory
+
+A delegating session factory is now available, enabling the selection of a particular session factory based on some
+thread context value.
+
+See <<ftp-dsf>> and <<sftp-dsf>> for more information.
+
+===== Default Sftp Session Factory
+
+Previously, the `DefaultSftpSessionFactory` unconditionally allowed connections to unknown hosts.
+This is now configurable (default false).
+
+The factory now requires a configured `knownHosts` file unless the `allowUnknownKeys` property is `true` (default
+false).
+
+See <<sftp-unk-hosts>> for more information.
+
+===== Message Session Callback
+
+The `MessageSessionCallback<F, T>` has been introduced to perform any custom `Session` operation(s) with the
+`requestMessage` context in the `<int-(s)ftp:outbound-gateway/>`.
+
+See <<ftp-session-callback>> and <<sftp-session-callback>> for more information.
+
+
+==== Websocket Changes
+
+`WebSocketHandlerDecoratorFactory` support has been added to the `ServerWebSocketContainer`
+to allow chained customization for the internal `WebSocketHandler`.
+See <<web-sockets-namespace>> for more information.
+
+==== Application Event Adapters changes
+
+The `ApplicationEvent` adapters can now operate with `payload` as `event` directly allow omitting custom
+`ApplicationEvent` extensions.
+The `publish-payload` boolean attribute has been introduced on the `<int-event:outbound-channel-adapter>` for this
+purpose.
+See <<applicationevent>> for more information.

-It is now possible to configure the reply listener in JMS outbound gateways to be initialized on-demand and stopped
-after an idle period, instead of being controlled by the gateway's lifecycle.
-
-See <<jms-outbound-gateway>> for more information.
-
-===== Conversion Errors in Message-Driven Endpoints
-
-The `error-channel` now is used for the conversion errors, which have caused a transaction rollback and message redelivery previously.
-
-See <<jms-message-driven-channel-adapter>> and <<jms-inbound-gateway>> for more information.
-
-===== Default Acknowledge Mode
-
-When using an implicitly defined `DefaultMessageListenerContainer`, the default `acknowledge` is now `transacted`.
-`transacted` is recommended when using this container, to avoid message loss.
-This default now applies to the message-driven inbound adapter and the inbound gateway, it was already the
-default for jms-backed channels.
-
-See <<jms-message-driven-channel-adapter>> and <<jms-inbound-gateway>> for more information.
-
-===== Shared Subscriptions
-
-Namespace support for shared subscriptions (JMS 2.0) has been added to message-driven endpoints and the
-`<int-jms:publish-subscribe-channel>`.
-Previously, you had to wire up listener containers as `<bean/>` s to use shared connections.
-
-See <<jms>> for more information.
-
-[[x4.2-conditional-pollers]]
-==== Conditional Pollers
-Much more flexibility is now provided for dynamic polling.
-
-See <<conditional-pollers>> for more information.
-
-[[x4.2-amqp-changes]]
-==== AMQP Changes
-
-===== Publisher Confirms
-
-The `<int-amqp:outbound-gateway>` now supports `confirm-correlation-expression` and `confirm-(n)ack-channel`
-attributes with similar purpose as for `<int-amqp:outbound-channel-adapter>`.
-
-===== Correlation Data
-
-For both the outbound channel adapter and gateway, if the correlation data is a `Message<?>`, it will be the basis
-of the message on the ack/nack channel, with the additional header(s) added.
-Previously, any correlation data (including `Message<?>`) was returned as the payload of the ack/nack message.
-
-===== The Inbound Gateway properties
-
-The `<int-amqp:inbound-gateway>` now exposes the `amqp-template` attribute to allow more control over an external bean
-for the reply `RabbitTemplate` or even provide your own `AmqpTemplate` implementation.
-In addition the `default-reply-to` is exposed to be used if request message doesn't have `replyTo` property.
-
-See <<amqp>> for more information.
-
-[[x4.2-xpath-splitter]]
-==== XPath Splitter Improvements
-
-The `XPathMessageSplitter` (`<int-xml:xpath-splitter>`) now allows the configuration of `output-properties`
-for the internal `javax.xml.transform.Transformer` and supports an `Iterator` mode (defaults to `true`) for the xpath
-evaluation `org.w3c.dom.NodeList` result.
-
-See <<xml-xpath-splitting>> for more information.
-
-[[x4.2-http-changes]]
-==== HTTP Changes
-
-===== CORS
-
-The HTTP Inbound Endpoints (`<int-http:inbound-channel-adapter>` and `<int-http:inbound-gateway>`) now allow the
-configuration of _Cross-Origin Resource Sharing (CORS)_.
-
-See <<http-cors>> for more information.
-
-===== Inbound Gateway Timeout
-
-The HTTP inbound gateway can be configured as to what status code to return when a request times out.
-The default is now `500 Internal Server Error` instead of `200 OK`.
-
-See <<http-response-statuscode>> for more information.
-
-===== Form Data
-
-Documentation is provided for when proxying `multipart/form-data` requests.
-See <<http>> for more information.
-
-[[x4.2-gw]]
-==== Gateway Changes
-
-===== Gateway Methods can Return CompletableFuture<?>
-
-When using Java 8, gateway methods can now return `CompletableFuture<?>`.
-See <<gw-completable-future>> for more information.
-
-===== MessagingGateway Annotation
-
-The request and reply timeout properties are now `String` instead of `Long` to allow configuration with property
-placeholders or SpEL. See <<messaging-gateway-annotation>>.
-
-[[x4.2-aggregator-changes]]
-==== Aggregator Changes
-
-===== Aggregator Performance
-
-This release includes some performance improvements for aggregating components (aggregator, resequencer, etc),
-by more efficiently removing messages from groups when they are released.
-New methods (`removeMessagesFromGroup`) have been added to the message store.
-Set the `removeBatchSize` property (default `100`) to adjust the number of messages deleted in each operation.
-Currently, JDBC, Redis and MongoDB message stores support this property.
-
-===== Output Message Group Processor
-
-When using a `ref` or inner bean for the aggregator, it is now possible to bind a `MessageGroupProcessor` directly.
-In addition, a `SimpleMessageGroupProcessor` is provided that simply returns the collection of messages in the group.
-When an output processor produces a collection of `Message<?>`, the aggregator releases those messages individually.
-Configuring the `SimpleMessageGroupProcessor` makes the aggregator a message barrier, were messages are held up
-until they all arrive, and are then released individually. See <<aggregator>> for more information.
-
-==== (S)FTP Changes
-
-===== Inbound channel adapters
-
-You can now specify a `remote-directory-expression` on the inbound channel adapters, to determine the directory
-at runtime.
-See <<ftp>> and <<sftp>> for more information.
-
-===== Gateway Partial Results
-
-When use FTP/SFTP outbound gateways to operate on multiple files (`mget`, `mput`), it is possible for an exception to
-occur after part of the request is completed.
-If such a condition occurs, a `PartialSuccessException` is thrown containing the partial results.
-See <<ftp-outbound-gateway>> and <<sftp-outbound-gateway>> for more information.
-
-===== Delegating Session Factory
-
-A delegating session factory is now available, enabling the selection of a particular session factory based on some
-thread context value.
-
-See <<ftp-dsf>> and <<sftp-dsf>> for more information.
-
-===== Default Sftp Session Factory
-
-Previously, the `DefaultSftpSessionFactory` unconditionally allowed connections to unknown hosts.
-This is now configurable (default false).
-
-The factory now requires a configured `knownHosts` file unless the `allowUnknownKeys` property is `true` (default
-false).
-
-See <<sftp-unk-hosts>> for more information.
-
-===== Message Session Callback
-
-The `MessageSessionCallback<F, T>` has been introduced to perform any custom `Session` operation(s) with the
-`requestMessage` context in the `<int-(s)ftp:outbound-gateway/>`.
-
-See <<ftp-session-callback>> and <<sftp-session-callback>> for more information.
-
-
-==== Websocket Changes
-
-`WebSocketHandlerDecoratorFactory` support has been added to the `ServerWebSocketContainer`
-to allow chained customization for the internal `WebSocketHandler`.
-See <<web-sockets-namespace>> for more information.
-
-==== Application Event Adapters changes
-
-The `ApplicationEvent` adapters can now operate with `payload` as `event` directly allow omitting custom
-`ApplicationEvent` extensions.
-The `publish-payload` boolean attribute has been introduced on the `<int-event:outbound-channel-adapter>` for this
-purpose.
-See <<applicationevent>> for more information.
