[released](/blog/2024/05/RELEASE-4.6.0/).
This release introduces a set of new features and noticeable improvements that
we will cover in this blog post.
-## Camel Core
+## Camel JBang
-TODO:
+We fixed some issues using Camel JBang with Windows, but we would still like
more feedback from Windows users.
-## Camel Main
+Camel JBang is __primary__ intended to be Camel standalone only. However, we
added
+support for running with Spring Boot or Quarkus directly.
-TODO:
+You use the `--runtime` option to specify which platform to use, as shown
below:
-## Camel JBang
+ $ camel run foo.camel.yaml --runtime=spring-boot
-We fixed some issues using Camel JBang with Windows, but we would still like
more feedback from Windows users.
+And for Quarkus:
+
+ $ camel run foo.camel.yaml --runtime=quarkus
+
+There are several limitations, one would be that Spring Boot and Quarkus
cannot automatically detect new components and download JARs.
+(you can stop and run again to update dependencies).
+
+You can now also configure logging levels per package name in
`application.properties` as shown below:
+
+ logging.level.org.apache.kafka = DEBUG
+ logging.level.com.foo.something = TRACE
+
+You can also do this using Quarkus _style_:
-TODO: Run with runtime
-TODO: logging level in application.properties
-TODO: datasource spring-boot style
+ quarkus.log.category."org.apache.kafka".level = DEBUG
+ quarkus.log.category."com.foo.something".level = TRACE
+And we also made it possible to define JDBC `DataSource` using Spring Boot
_style_ directly in `application.properties` as follows:
+
+ spring.datasource.url=
jdbc:sqlserver://db.example.net:1433;databaseName=test_db
+ spring.datasource.username=user
+ spring.datasource.password=password
+
spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver

## Rest DSL with contract first
-TODO:
+The Rest DSL has been improved with a _contract first_ approach using vanilla
OpenAPI specification.
+
+The _contract first_ approach requires you to have an existing OpenAPI v3
specification file.
+This contract is a standard OpenAPI contract, and you can use any existing API
design tool to build such contracts.
+
+This makes it super easy to define Rest DSL in Camel from an existing OpenAPI
specification file, all you do
+is to declare this small piece of Rest DSL code:
+
+For example in Java DSL:
+
+ public void configure() throws Exception {
+ rest().openApi("petstore-v3.json");
+ }
+
+The `petstore-v3.json` is the OpenAPI specification file, and Camel will
automatically parse and map each API endpoint
+to a Camel route with the `direct:operationId` convention.
+
+During development of these API endpoints in Camel you can tell Camel to
ignore missing routes, so you can build, run, and test
+this one API at a time.
+
+Here is an example for Camel Spring Boot:
https://github.com/apache/camel-spring-boot-examples/tree/main/openapi-contract-first
+And here is an example for YAML DSL with JBang:
