-### Building and Testing
+### Building and Unit Testing
 
->**Note**: Build and test instructions have recently changed. The ```pom.client.xml``` file is no
-> longer in the root of the repository and should be not be used as an aggregator moving forward.
-
-This repository uses Maven to build the various modules that make up the Azure SDK for Java. You can build the entire set of modules by running the following command from the root of the repository:
-
-```
-mvn -Dgpg.skip clean install
-```
-
-This will build, test and install all of the modules into your local Maven cache. Optionally, you
-can also skip unit test execution by issuing the following command. This can be useful when you
-just want to try out a quick change without having to worry about unit tests.
-
-```
-mvn -Dgpg.skip -DskipTests clean install
-```
-
-If you only want to work on one module, you may opt to build just that module and its dependencies (e.g. com.azure:azure-messaging-eventhubs):
-
-```
-mvn -Dgpg.skip -DskipTests -pl com.azure:azure-messaging-eventhubs -am
-```
-
-The ```-pl``` switch takes a comma seperated list of fully qualified module names and the ```-am```
-switch tells Maven to _also make_ all of the dependencies within the repository that it depends on. If
-you are making changes across two modules you can tell Maven to build them both like this:
-
-```
-mvn -Dgpg.skip -DskipTests -pl com.azure:azure-messaging-eventhubs,com.azure:azure-core-amqp -am
-```
-
-Some parts of the SDK have multiple modules for a particular service, if you want to avoid typing
-in all those module names for the ```-pl``` switch you can just target the appropriate POM file
-(e.g. sdk/eventhubs/pom.xml) and execute the following command.
-
-```
-mvn -f sdk/eventhubs/pom.xml -Dgpg.skip clean install
-```
-
-Note that any dependencies for those modules will need to be in the Maven cache so will want to run
-the first command listed above once to get the cache primed with all the dependencies.
-
->**Note**: Refer to [wiki](https://github.com/Azure/azure-sdk-for-java/wiki/Building) for learning about how to build using Java 11 
->and [this wiki](https://github.com/Azure/azure-sdk-for-java/wiki/Unit-Testing) for guidelines on unit testing
+Refer to the [build wiki](https://github.com/Azure/azure-sdk-for-java/wiki/Building) for learning how to build Java SDKs

 ## Key concepts
 ### Certificate
-  Azure Key Vault supports certificates with secret content types(`PKCS12` & `PEM`). The certificate can be backed by keys in key vault of types(`EC` & `RSA`). In addition to the certificate policy, the following attributes may be specified:
-* enabled: Specifies whether the certificate is enabled and useable.

+* enabled: Specifies whether the certificate is enabled and usable.
 * created: Indicates when this version of the certificate was created.
 * updated: Indicates when this version of the certificate was updated.
 
-### Certificate Client:
-The Certificate client performs the interactions with the Azure Key Vault service for getting, setting, updating, deleting, and listing certificates and its versions. The client also supports CRUD operations for certificate issuers and contacts in the key vault. An asynchronous and synchronous, CertificateClient, client exists in the SDK allowing for selection of a client based on an application's use case. Once you've initialized a Certificate, you can interact with the primary resource types in Key Vault.

 ## Troubleshooting
 ### General
-Certificate Vault clients raise exceptions. For example, if you try to retrieve a certificate after it is deleted a `404` error is returned, indicating resource not found. In the following snippet, the error is handled gracefully by catching the exception and displaying additional information about the error.
+Azure Key Vault Certificate clients raise exceptions. For example, if you try to retrieve a certificate after it is deleted a `404` error is returned, indicating the resource was not found. In the following snippet, the error is handled gracefully by catching the exception and displaying additional information about the error.
 
 ```java

 } catch (ResourceNotFoundException e) {
     System.out.println(e.getMessage());
 }
 ```
 
-### Default HTTP Client
-All client libraries by default use the Netty HTTP client. Adding the above dependency will automatically configure 
-the client library to use the Netty HTTP client. Configuring or changing the HTTP client is detailed in the
-[HTTP clients wiki](https://github.com/Azure/azure-sdk-for-java/wiki/HTTP-clients).

 ### Default SSL library
-All client libraries, by default, use the Tomcat-native Boring SSL library to enable native-level performance for SSL 
-operations. The Boring SSL library is an uber jar containing native libraries for Linux / macOS / Windows, and provides 
-better performance compared to the default SSL implementation within the JDK. For more information, including how to 
-reduce the dependency size, refer to the [performance tuning][performance_tuning] section of the wiki.

-Agreement (CLA) declaring that you have the right to, and actually do, grant us the rights to use your contribution. For
-details, visit https://cla.microsoft.com.
-
-When you submit a pull request, a CLA-bot will automatically determine whether you need to provide a CLA and decorate
-the PR appropriately (e.g., label, comment). Simply follow the instructions provided by the bot. You will only need to
-do this once across all repositories using our CLA.
-
-## Code of conduct
-
-This project has adopted the [Microsoft Open Source Code of Conduct](https://opensource.microsoft.com/codeofconduct/).
-For more information see the [Code of Conduct FAQ](https://opensource.microsoft.com/codeofconduct/faq/) or contact
-[opencode@microsoft.com](mailto:opencode@microsoft.com) with any additional questions or comments.
-
-## Getting started
-
-Before working on a contribution, it would be beneficial to familiarize yourself with the process and guidelines used
-for the Azure SDKs so that your submission is consistent with the project standards and is ready to be accepted with
-fewer changes requested. In particular, it is recommended to review:
-
-- [Azure SDK README][github-general], to learn more about the overall project and processes used.
-- [Azure SDK Design Guidelines][design-guidelines], to understand the general guidelines for the SDKs across all
-  languages and platforms
-- [Azure SDK Design Guidelines for Java][java-spec], to understand the guidelines specific to the Azure SDKs for Java.
-
-## Development environment setup
-
-### Prerequisites
-
-- Java Development Kit (JDK) with version 8 or above
-- [Maven][maven]
-- Git
-- Microsoft Azure subscription
-    - You can create a free account at: https://azure.microsoft.com
-
-## Building all the client libraries
-
-Open a command prompt/terminal:
-1. Execute `git clone https://github.com/Azure/azure-sdk-for-java.git`
-2. Traverse to the repository root.
-3. Execute `mvn compile -f pom.client.xml`
-4. Install the tooling and build the product by executing:
-    * `mvn install -Dinclude-non-shipping-modules -DskipTests -Dgpg.skip -f pom.client.xml`
-
-## Building only the Azure SDK client library for Service Bus
-
-After building the tooling and solution once from the section, [Building all the client libraries](#building-all-the-client-libraries), you can build just the Azure SDK client library for Service Bus by
-executing:
-1. `mvn compile -f servicebus\azure-messaging-servicebus\pom.xml`
-
-## Running tests
-
-After following instructions in [Building all the client libraries](#building-all-the-client-libraries), you can run the
-unit tests by executing:
-1. `mvn test -f servicebus\azure-messaging-servicebus\pom.xml`
-
-For unit tests, there are no special considerations; these are self-contained and execute locally without any reliance
-on external resources. These tests are run for all PR validations.
-
-### Running integration tests
-
-Integration tests have dependencies on live Azure resources and require setting up your development environment prior
-to running. Known in the Azure SDK project commonly as "Live" tests, these tests only run when the
-[`TestMode`][test-mode] is equal to [`TestMode.RECORD`][test-mode-record]. The Live tests read information from the
-following environment variables:
-
-- AZURE_TEST_MODE
-    - Can be either "RECORD" or "PLAYBACK". If AZURE_TEST_MODE is equal to "RECORD", then the tests will run against the
-      live service.
-- AZURE_SERVICEBUS_CONNECTION_STRING
-    - The connection string to the Azure Service Bus instance. This is required when running tests in RECORD mode. It must
-      contain the name of the Service Bus instance (the `EntityPath=` component must be in the connection string).
-
-## Logging output
-
-Log messages can be seen in the output window by:
-1. Setting `AZURE_LOG_LEVEL` to the desired verbosity. Log levels can be found in [ClientLogger][log-level]
-1. Adding an implementation of [slf4j][slf4j] to the classpath. Implementations can be found under section "[Binding with a
-   logging framework at deployment time][slf4j-implementations]".

 ## Key concepts
 
 You can interact with the primary resource types within a Service Bus Namespace, of which multiple can exist and
-on which actual message transmission takes place, the namespace often serving as an application container:
-
-* [Queue][queue_concept]: Allows for Sending and Receiving of messages, ordered first-in-first-out.  Often used for
-point-to-point communication.
+on which actual message transmission takes place. The namespace often serves as an application container:
 
-* [Topic][topic_concept]: As opposed to Queues, Topics are better suited to publish/subscribe scenarios.  A topic can
-be sent to, but requires a subscription, of which there can be multiple in parallel, to consume from.
-
-* [Subscription][subscription_concept]: The mechanism to consume from a Topic.  Each subscription is independent, and
-receaves a copy of each message sent to the topic.
+* A **[queue][queue_concept]** allows for the sending and receiving of messages, ordered first-in-first-out. It is often
+  used for point-to-point communication.
+* A **[topic][topic_concept]** is better suited to publisher and subscriber scenarios. A topic publishes messages to
+  subscriptions, of which, multiple can exist simultaneously.
+* A **[subscription][subscription_concept]** receives messages from a topic. Each subscription is independent and
+  receives a copy of the message sent to the topic.
 
 ## Examples
 
-### Create a sender or receiver using connection string
-
-The easiest means for doing so is to use a connection string, which is created automatically when creating an Service Bus
-namespace. If you aren't familiar with shared access policies in Azure, you may wish to follow the step-by-step guide to
-[get an Service Bus connection string][service_bus_connection_string].
+### Send messages
 
-Both the asynchronous and synchronous Service Bus sender and receiver clients can be created using
-`ServiceBusClientBuilder`.The examples are explained blow.
+You'll need to create an asynchronous [`ServiceBusSenderAsyncClient`][ServiceBusSenderAsyncClient] or a synchronous
+[`ServiceBusSenderClient`][ServiceBusSenderClient] to send messages. Each sender can send messages to either a queue or
+a topic.

+#### Receive a batch of messages
 
-<!-- embedme ./src/samples/java/com/azure/messaging/servicebus/ReadmeSamples.java#L35-L41 -->
+The snippet below creates a `ServiceBusReceiverClient` to receive messages from a topic subscription. It returns a batch
+of messages when 10 messages are received or until 30 seconds have elapsed, whichever happens first.
+
+<!-- embedme ./src/samples/java/com/azure/messaging/servicebus/ReadmeSamples.java#L81-L94 -->
 ```java
-String connectionString = "<< CONNECTION STRING FOR THE SERVICE BUS NAMESPACE >>";
-ServiceBusReceiverAsyncClient receiver = new ServiceBusClientBuilder()
-    .connectionString(connectionString)
+ServiceBusReceiverClient receiver = new ServiceBusClientBuilder()
+    .connectionString("<< CONNECTION STRING FOR THE SERVICE BUS NAMESPACE >>")
     .receiver()
     .topicName("<< TOPIC NAME >>")
     .subscriptionName("<< SUBSCRIPTION NAME >>")
+    .receiveMode(ReceiveMode.PEEK_LOCK)
+    .buildClient();
+
+IterableStream<ServiceBusReceivedMessageContext> messages = receiver.receive(10, Duration.ofSeconds(30));
+messages.forEach(context -> {
+    ServiceBusReceivedMessage message = context.getMessage();
+    System.out.printf("Id: %s. Contents: %s%n", message.getMessageId(),
+        new String(message.getBody(), StandardCharsets.UTF_8));
+});
+```
+
+#### Receive a stream of messages
+
+The asynchronous `ServiceBusReceiverAsyncClient` continuously fetches messages until the `subscription` is disposed.
+
+<!-- embedme ./src/samples/java/com/azure/messaging/servicebus/ReadmeSamples.java#L101-L115 -->
+```java
+ServiceBusReceiverAsyncClient receiver = new ServiceBusClientBuilder()
+    .connectionString("<< CONNECTION STRING FOR THE SERVICE BUS NAMESPACE >>")
+    .receiver()
+    .queueName("<< QUEUE NAME >>")
     .buildAsyncClient();
+
+Disposable subscription = receiver.receive().subscribe(context -> {
+    ServiceBusReceivedMessage message = context.getMessage();
+    System.out.printf("Id: %s%n", message.getMessageId());
+    System.out.printf("Contents: %s%n", new String(message.getBody(), StandardCharsets.UTF_8));
+}, error -> {
+        System.err.println("Error occurred while receiving messages: " + error);
+    }, () -> {
+        System.out.println("Finished receiving messages.");
+    });
+```
+
+### Settle messages
+
+When a message is received, it can be settled using any of the `complete()`, `abandon()`, `defer()`, or `deadLetter()`
+overloads. The sample below completes a received message from synchronous `ServiceBusReceiverClient`.
+
+<!-- embedme ./src/samples/java/com/azure/messaging/servicebus/ReadmeSamples.java#L130-L135 -->
+```java
+receiver.receive(10).forEach(context -> {
+    ServiceBusReceivedMessage message = context.getMessage();
+
+    // Process message and then complete it.
+    receiver.complete(message);
+});
 ```
+There are four ways of settling messages:
+  - Complete - causes the message to be deleted from the queue or topic.
+  - Abandon - releases the receiver's lock on the message allowing for the message to be received by other receivers.
+  - Defer - defers the message from being received by normal means. In order to receive deferred messages, the sequence 
+number of the message needs to be retained.
+  - Dead-letter - moves the message to the [dead-letter queue](https://docs.microsoft.com/azure/service-bus-messaging/service-bus-dead-letter-queues). This will prevent the message from being received again. 
+In order to receive messages from the dead-letter queue, a receiver scoped to the dead-letter queue is needed.
 
-### Sending messages
 
-You'll need to create an asynchronous [`ServiceBusSenderAsyncClient`][ServiceBusSenderAsyncClient] or
-a synchronous [`ServiceBusSenderClient`][ServiceBusSenderClient] to send message. Each sender can send message to either, a queue,
-or topic.
+### Send and receive from session enabled queues or topics
 
-* [Sending a message asynchronously][sample-send-async-message].
-* [Sending a message asynchronously using active directory credential][sample-send-async-aad-message].
-* [Send message in batch synchronously][sample-send-batch-messages].
+> Using sessions requires you to create a session enabled queue or subscription. You can read more about how to
+> configure this in "[Message sessions][message-sessions]".
 
-### Receiving messages
+Unlike non-session-enabled queues or subscriptions, only a single receiver can read from a session at any time. When a
+receiver fetches a session, Service Bus locks the session for that receiver, and it has exclusive access to messages in
+that session.
 
-You'll need to create an asynchronous [`ServiceBusReceiverAsyncClient`][ServiceBusReceiverAsyncClient] or

+Create a `ServiceBusSenderClient` for a session enabled queue or topic subscription. Setting `.setSessionId(String)` on
+a `ServiceBusMessage` will publish the message to that session. If the session does not exist, it is created.
+
+<!-- embedme ./src/samples/java/com/azure/messaging/servicebus/ReadmeSamples.java#L148-L151 -->
+```java
+ServiceBusMessage message = new ServiceBusMessage("Hello world".getBytes())
+    .setSessionId("greetings");
+
+sender.send(message);
+```
+
+#### Receive messages from a session
+
+Receivers can fetch messages from a specific session or the first available, unlocked session. The first snippet creates
+a receiver for a session with id "greetings". The second snippet creates a receiver that fetches the first available
+session.
+
+<!-- embedme ./src/samples/java/com/azure/messaging/servicebus/ReadmeSamples.java#L158-L163 -->
+```java
+ServiceBusReceiverAsyncClient receiver = new ServiceBusClientBuilder()
+    .connectionString("<< CONNECTION STRING FOR THE SERVICE BUS NAMESPACE >>")
+    .sessionReceiver()
+    .queueName("<< QUEUE NAME >>")
+    .sessionId("greetings")
+    .buildAsyncClient();
+```
+
+<!-- embedme ./src/samples/java/com/azure/messaging/servicebus/ReadmeSamples.java#L170-L174 -->
+```java

 ## Troubleshooting
 
 ### Enable client logging
 
-You can set the `AZURE_LOG_LEVEL` environment variable to view logging statements made in the client library. For
-example, setting `AZURE_LOG_LEVEL=2` would show all informational, warning, and error log messages. The log levels can
-be found here: [log levels][LogLevels].
+Azure SDK for Java offers a consistent logging story to help aid in troubleshooting application errors and expedite
+their resolution. The logs produced will capture the flow of an application before reaching the terminal state to help
+locate the root issue. View the [logging][logging] wiki for guidance about enabling logging.
 
 ### Enable AMQP transport logging

 exception occurred and if possible, how to mitigate this exception. A list of all the AMQP exceptions can be found in
 [OASIS AMQP Version 1.0 Transport Errors][oasis_amqp_v1_error].
 
-The [`AmqpErrorContext`][AmqpErrorContext] in the [`AmqpException`][AmqpException] provides information about the AMQP
-session, link, or connection that the exception occurred in. This is useful to diagnose which level in the transport
-this exception occurred at and whether it was an issue in one of the producers or consumers.
-
-#### Operation cancelled exception
-
-It occurs when the underlying AMQP layer encounters an abnormal link abort or the connection is disconnected in an
-unexpected fashion. It is recommended to attempt to verify the current state and retry if necessary.
-
-### Handling transient AMQP exceptions
-
-If a transient AMQP exception occurs, the client library retries the operation as many times as the
-[AmqpRetryOptions][AmqpRetryOptions] allows. Afterwards, the operation fails and an exception is propagated back to the
-user.
-
-### Default SSL library
-
-All client libraries, by default, use the Tomcat-native Boring SSL library to enable native-level performance for SSL
-operations. The Boring SSL library is an uber jar containing native libraries for Linux / macOS / Windows, and provides
-better performance compared to the default SSL implementation within the JDK. For more information, including how to

 # Release History
 
 ## 1.0.0-beta.5 (Unreleased)
+**New features**
+- Added Text property and `getText()` to `SentenceSentiment`.
+- `Warnings` property added to each document-level response object returned from the endpoints. It is a list of `TextAnalyticsWarnings`.
+- Added `CategorizedEntityCollection`, `KeyPhrasesCollection`, `LinkedEntityCollection` for having `getWarnings()` to retrieve warnings. 
+- Added a new enum value `ADDRESS` to `EntityCategory`.
+- Text analytics SDK update the service to version `v3.0` from `v3.0-preview.1`.
 
-
+**Breaking changes**
+- Renamed `apiKey()` to `credential()` on TextAnalyticsClientBuilder.
+- Removed `getGraphemeLength()` and `getGraphemeOffset()` from `CategorizedEntity`, `SentenceSentiment`, and `LinkedEntityMatch`.
+- `getGraphemeCount()` in `TextDocumentStatistics` has been renamed to `getCharacterCount()`.
+- `getScore()` in `DetectedLanguage` has been renamed to `getConfidenceScore()`.
+- `getSubCategory()` in `CategorizedEntity` has been renamed to `getSubcategory()`.
+- `getLinkedEntityMatches()` in `LinkedEntity` has been renamed to `getMatches()`.
+- `getCode()` in `TextAnalyticsException` and `TextAnalyticsError` has been renamed to `getErrorCode()`.
+- `getCode()` in `TextAnalyticsWarning` has been renamed to `getWarningCode()`.
+- Async client returns errors, mono error or flux error but no longer throws exception. Sync client throws exceptions only.
+- Deprecated `TextDocumentInput(String id, String text, String language)` constructor, but added `setLanguage()` setter since `language` is optional.
+- Renamed `RecognizeCategorizedEntitiesResult` to `RecognizeEntitiesResult`.
+- Renamed `DocumentResult` to `TextAnalyticsResult`.
+- Removed `getServiceVersion()` from both synchronous and asynchronous clients.
+- Replaced all single input asynchronous APIs, e.x., 
+  - `TextAnalyticsPagedFlux<CategorizedEntity> recognizeEntities(String document)` to `Mono<CategorizedEntityCollection> recognizeEntities(String document)`.
+  - `TextAnalyticsPagedFlux<LinkedEntity> recognizeLinkedEntities(String document)` to `Mono<LinkedEntityCollection> recognizeLinkedEntities(String document)`.
+  - `TextAnalyticsPagedFlux<String> extractKeyPhrases(String document)` to `Mono<KeyPhrasesCollection> extractKeyPhrases(String document)`.
+- Replaced all single input synchronous APIs, e.x., 
+  - `TextAnalyticsPagedIterable<CategorizedEntity> recognizeEntities(String document)` to `CategorizedEntityCollection recognizeEntities(String document)`.
+  - `TextAnalyticsPagedIterable<LinkedEntity> recognizeLinkedEntities(String document)` to `LinkedEntityCollection recognizeLinkedEntities(String document)`.
+  - `TextAnalyticsPagedIterable<String> extractKeyPhrases(String document)` to `KeyPhrasesCollection extractKeyPhrases(String document)`.
+  
 ## 1.0.0-beta.4 (2020-04-07)
 - Throws an illegal argument exception when the given list of documents is an empty list.

 An operation result, such as `AnalyzeSentimentResult`, is the result of a Text Analytics operation, containing a 
-prediction or predictions about a single document. An operation's result type also may optionally include information
-about the input document and how it was processed. An operation result contains a `isError` property that allows to
-identify if an operation executed was successful or unsuccessful for the given document. When the operation results
-an error, you can simply call `getError()` to get `TextAnalyticsError` which contains the reason why it is unsuccessful.
