+## Hibernate Search + Elasticsearch (Preview)
+
+`quarkus.hibernate-search.elasticsearch.automatic-indexing.synchronization.strategy` has been renamed to `quarkus.hibernate-search.automatic-indexing.synchronization.strategy`.
+
+If you are using our Hibernate Search + Elasticsearch extension, there's a good chance you will need to adjust your configuration.
+
+## Neo4j (Preview)
+
+The Neo4j driver was updated to the Final 4.0 version and they have renamed a few classes, most notably `org.neo4j.driver.reactive.RxResult.RxStatementResult` has been renamed to `org.neo4j.driver.reactive.RxResult`.
+
+## Gradle plugin
+
+We now recommend using Gradle 6.0.1+. Starting from this version the Gradle plugin is no longer deployed in Maven Central, therefore some minor changes in your Gradle project might be needed. 
+
+### Changes in the `settings.gradle` file
+
+Let's start by changing the `settings.gradle` file. It should be changed from (`rootProject.name` value may vary depending on your project name):
+
+```gradle
+pluginManagement {
+    repositories {
+        mavenLocal()
+        mavenCentral()
+        gradlePluginPortal()
+    }
+    resolutionStrategy {
+        eachPlugin {
+            if (requested.id.id == 'io.quarkus') {
+                useModule("io.quarkus:quarkus-gradle-plugin:1.0.1.Final")
+            }
+        }
+    }
+}
+
+rootProject.name='my-project'
+```
+to: 
+```gradle
+pluginManagement {
+    repositories {
+        mavenLocal()
+        mavenCentral()
+        gradlePluginPortal()
+    }
+    plugins {
+      id 'io.quarkus' version "${quarkusPluginVersion}"
+    }
+}
+rootProject.name='my-project'
+```
+
+NOTE: the `plugins{}` method is not supported in Gradle 5.x. In this case make sure to explicitly declare the plugin version in the `build.gradle` file.
+
+### Changes in the `build.gradle` file
+
+Change your `build.gradle` file to use the plugin DSL format, from:
+
+```gradle
+// this block is necessary to make enforcedPlatform work for Quarkus plugin available
+// only locally (snapshot) that is also importing the Quarkus BOM
+buildscript {
+    repositories {
+        mavenLocal()
+    }
+    dependencies {
+        classpath "io.quarkus:quarkus-gradle-plugin:${quarkusPluginVersion}"
+    }
+}
+
+plugins {
+    id 'java'
+}
+
+apply plugin: 'io.quarkus'
+```
+to: 
+```gradle
+plugins {
+   id 'java'
+   id 'io.quarkus'
+}
+
+```
+
+## Extension framework
+
+### Updated configuration framework
+
+Our configuration framework got a big update to fix a number of issues all around.
+
+The main consequence of this change is that you will need to mark optional collections and maps as `Optional` in your config classes (that means `Optional<List<String>>` for instance).
+
+### GizmoAdaptor
+
+The `GizmoAdaptor` class has been renamed to `GeneratedClassGizmoAdaptor`, due to the introduction of `GeneratedBeanGizmoAdaptor`.

+## Hibernate ORM
+
+* `quarkus.hibernate-orm.log.bind-param` is deprecated and has been renamed `quarkus.hibernate-orm.log.bind-parameters`. The former will be removed at a later stage.
+
+## Hibernate Search ORM + Elasticsearch (Preview)
+
+* You should update your Maven/Gradle dependencies: replace any occurrence of the artifact ID `hibernate-search-elasticsearch` with `hibernate-search-orm-elasticsearch`
+* You should update your configuration: replace any occurrence of the prefix `quarkus.hibernate-search.` with `quarkus.hibernate-search-orm.
+* Many deprecated methods and classes were removed. For more information: https://in.relation.to/2020/11/04/hibernate-search-6-0-0-CR1/#breaking_changes
+* Async/reactive methods now return `CompletionStage` instead of `CompletableFuture`. To convert a `CompletionStage` to a `Future`, call `.toCompletableFuture()`.`
+
+## MongoDB
+
+* The name of the default client is now `<default>` instead of the previous `__default__` to be more consistent with the rest of the code base. It shouldn't have too many consequences but typically the health checks now expose the new name.

+## Log min-level
+
+If you are using TRACE (or DEBUG too if using 1.11.0.Final or 1.11.1.Final - changed in 1.11.2.Final) log level, we made an important change in our logging layer: a new build-time `min-level` configuration property was introduced that sets the minimum log level you will be able to use at runtime.
+
+So if you are logging at TRACE level for some loggers, setting `min-level` to TRACE is required.
+
+## Non-application endpoints moved to their own namespace
+
+[Path resolution for configurable endpoints](https://quarkus.io/blog/path-resolution-in-quarkus/) changed in this release. This transition was a little rough. There are some differences in behavior between 1.11.0.Final, when this was introduced, and 1.11.5.Final, when issues were resolved. 
+
+By default, non-application endpoints, like health and metrics, are now grouped under `/q`.
+
+Convenience redirects from previous URLs to new namespaced URLs can be enabled and disabled by setting:  
+`quarkus.http.redirect-to-non-application-root-path=false`
+
+Disable the Quarkus non-application endpoints by setting the non-application endpoint root to be the same as the http root: 
+`quarkus.http.non-application-root-path=${quarkus.http.root-path}`
+
+You can customize the root used for non-application endpoints by setting `quarkus.http.non-application-root-path` to an alternative path. 
+
+As of 1.11.5.Final, leading slashes in configured paths are significant. Please see [Path resolution in Quarkus](https://quarkus.io/blog/path-resolution-in-quarkus/) for more details and examples.
+
+## Jackson
+
+The default `ObjectMapper` obtained via CDI and consumed by the Quarkus extensions now ignores unknown properties (by disabling the `DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES` feature).
+
+See https://quarkus.io/guides/rest-json#jackson for more details about how to go back to the previous behavior.
+
+## Kubernetes Client
+
+We upgraded the Kubernetes Client to version 5. Please refer to the [Kubernetes Client migration guide](https://github.com/fabric8io/kubernetes-client/blob/master/doc/MIGRATION-v5.md) for more information.
+
+## Hibernate Search ORM + Elasticsearch
+
+* The default required status for Elasticsearch indexes is now `yellow`. If you have specific requirements and need to wait for indexes to be `green` on startup, set `quarkus.hibernate-search.elasticsearch.schema-management.required-status` to `green`.
+* [Queries](https://docs.jboss.org/hibernate/search/6.0/reference/en-US/html_single/#troubleshooting-logging-query)
+and [requests](https://docs.jboss.org/hibernate/search/6.0/reference/en-US/html_single/#troubleshooting-logging-elasticsearch-request)
+are now logged at the `TRACE` level instead of the `DEBUG` level.
+
+## MongoDB Panache
+
+* A recent change was made to MongoDB panache to bring it in to conformity with the Hibernate Panache behavior.  Public field accesses on `MongoEntity` and `ReactiveMongoEntity` types are now wrapped with the appropriate `get` or `set` methods.  In general, you will like not see any difference in your application.  However, if you have written a custom `get` or `set` method you may notice a change in behavior if those custom methods deviate from the standard `get`/`set` paradigm.  See [this issue](https://github.com/quarkusio/quarkus-quickstarts/pull/726) for an example of something you might run in to.

+## quarkus-smallrye-jwt-build
+
+A new `quarkus-smallrye-jwt-build` extension has been introduced allowing users to generate JWT tokens without having to depend on `quarkus-smallrye-jwt` extension which is used for verifying JWT tokens.
+
+## GraalVM 20.3
+
+We upgraded the base container image to build native executables to GraalVM 20.3.
+
+However, we hit a regression in the ImageIO support so if you are using ImageIO and seeing errors such as `UnsatisfiedLinkError: no awt in java.library.path`. This regression is specific to GraalVM 20.3.0 and will be fixed in GraalVM 20.3.1. Your options are:
+
+* Go back to GraalVM 20.2 until we upgrade to GraalVM 20.3.1: `quarkus.native.builder-image=quay.io/quarkus/ubi-quarkus-native-image:20.2.0-java11`
+* Use [Mandrel](https://github.com/graalvm/mandrel/releases) in which we backported some additional ImageIO support from GraalVM master: `quarkus.native.builder-image=quay.io/quarkus/ubi-quarkus-mandrel:20.3-java11`
