+title: "Apache Camel 4.3 What's New"
+date: 2023-12-18
+authors: [davsclaus,gzurowski,orpiske,apupier]
+categories: ["Releases"]
+preview: Details of what we have done in the Camel 4.3 release.
+---
+
+Apache Camel 4.3 (non LTS) has just been [released](/blog/2023/12/RELEASE-4.3.0/).
+
+This release introduces a set of new features and noticeable improvements that we will cover in this blog post.
+
+## Camel Core
+
+Added basic support for Java 21 virtual threads. Note this is experimental and there is more work to complete
+to have full support for virtual threads. More details at [threading model](/manual/threading-model.html).
+
+The simple language can now work better with JSon and XML with inlined jq/jsonpath/xpath functions. This
+can be used for basic message transformation. You can find an examples at:
+
+- [json transformation](https://github.com/apache/camel-kamelets-examples/tree/main/jbang/json-transform)
+- [xml transformation](/components/next/languages/xpath-language.html#_transforming_a_xml_message)
+
+We plan to record a video on doing basic message transformation with json and xml with live updates using Camel JBang.
+
+We added `debugStandby` option to allow route debugging a running Camel application on demand. Being in standby mode
+has no overhead and only when debugging is activated then Camel runs in debugging mode, which can then be deactivated
+to go back to run in normal mode.
+
+## Camel Main
+
+Added support for Prometheus in the new `camel-micrometer-prometheus` component, that makes it possible to expose
+metrics in Prometheus format.
+
+This can be configured in `application.properties`:
+
+- Micrometer and Prometheus options using `camel.metrics.`
+
+## DSL
+
+We added the following EIPs:
+
+- `setHeaders` EIP to make it easier and less verbose to set multiple headers from the same EIP.
+- `convertHeaderTo` EIP to make it easy to convert header value to a specific type.
+
+The `throttler` EIP has been refactored to throttle based on concurrent requests instead of sliding window.
+
+We improved configuring beans, that can now support builder beans, that are used to build the actual bean.
+For example in the following YAML notice how the `builderClass` refers to class responsible for building the target bean:
+
+```yaml
+- beans:
+ - name: myCustomer
+ type: com.mycompany.Customer
+ builderClass: com.mycompany.CustomerBuilder
+ properties:
+ name: "Acme"
+ street: "Somestreet 42"
+ zip: 90210
+ gold: true
+- from:
+ uri: "timer:yaml"
+ parameters:
+ period: "5000"
+ steps:
+ - bean:
+ ref: myCustomer
+ method: summary
+ - log: "${body}"
+```
+
+The builder class is required to have a build method that Camel invokes. The name of the method is `build` by default.
+
+To see more see the following examples:
+
+- https://github.com/apache/camel-kamelets-examples/tree/main/jbang/bean-builder
+- https://github.com/apache/camel-kamelets-examples/tree/main/jbang/bean-inlined-code
+
+## Camel JBang (Camel CLI)
+
+We have continued investing in Camel JBang, and this time we have some great new stuff in the release.
+
+We have added support for using JBang style for declaring dependencies by using `//DEPS ` code comments, as shown
+in the following Java file:
+
+```java
+//DEPS org.apache.camel:camel-bom:4.3.0@pom
+//DEPS org.apache.camel:camel-endpointdsl
+//DEPS org.apache.camel:camel-kubernetes
+//DEPS org.apache.camel:camel-aws2-s3
+
+import org.apache.camel.builder.endpoint.EndpointRouteBuilder;
+
+public class foo extends EndpointRouteBuilder {
+
+ @Override
+ public void configure() {
+ from(timer("trigger").delay(1000).repeatCount(1))
+ // something that may use Java APIs from Kubernetes
+ }
+}
+```
+
+You can now also easily use JBang way of editing source code in your favorite editor, such as `jbang edit -b foo.java`.
+You can see more in the [jbang-edit example](https://github.com/apache/camel-kamelets-examples/tree/main/jbang/jbang-edit).
+
+TODO: JBang Transform message
+
+We have improved the `camel export` to avoid starting some services that was not needed, which could potentially
+cause the export to tail or take longer time.
+
+Camel JBang now accurately reports resolved vs download for dependency resolution. Previously it may report downloading
+but the dependency was resolved from local disk. You can also run in `--verbose` mode that shows verbose details
+for dependency resolution that can be useful for troubleshooting.
+
+Camel JBang export to `camel-main` can now configure authentication for container image registries.
+
+Camel JBang is also improved in hot reload mode `--dev` to let Java compiler compile all changed files in same compilation unit.
Review Comment:
I do not understand what it means. Can you clarify it a bit please?
