+title: "Apache Camel 3.15 What's New"
+date: 2022-02-04
+authors: [davsclaus, orpiske]
+categories: ["Releases"]
+preview: Details of what we have done in the Camel 3.15 release.
+---
+
+Apache Camel 3.15 has just been [released](/blog/2022/02/RELEASE-3.15.0/).
+
+This release has **dropped** support for Java 8, and therefore Java 11 is
required.
+
+Because this is first release where we upgrade from Java 8 to 11, then some
effort has been made
+to migrate various Maven plugins and settings to make this upgrade possible.
+
+This release introduces a set of new features and noticeable improvements that
we will cover in this blog post.
+
+### Camel Route source file:line
+
+When Camel startup then the DSL parser will now include the source file and
line number
+for every EIPs in the routes. (Java DSL requires to turn this on).
+
+The illustration below shows message tracing outputting in the log which
file:line the
+message is being routed at:
+
+
+
+Using this also allows Camel to give the exact route location,
+such as where an exception was thrown during routing.
+
+That is not all, as this also makes it possible to build route debugger for
all the DSLs.
+
+### Route Debugger
+
+Camel now comes with support for route debugger for tooling.
+
+The Camel IDEA plugin already supports this, which makes it possible
+to do step by step debugging in Java, XML, YAML, Groovy, Kotlin routes.
+
+
+
+You can read more about the debugger in this [blog
post](/blog/2021/12/camelDebuggerForIntelliJ/).
+
+The Camel Tooling team is currently working on debugging support for other
IDEs such as VSCode and Eclipse.
+
+### Alternative Dynamic Router
+
+An alternative Dynamic Router EIP has been implemented as a new component.
+You can find details about this from this [blog
post](/blog/2022/01/dynamic-router-eip-component/).
+
+### Running Camel K locally
+
+The `camel-yaml-dsl` is now capable of loading Camel K source files
(Integration and Binding), meaning you
+can run and test locally integrations that are intended for Camel K.
+
+This works well with Camel JBang, meaning that you can get a _Camel K like_
development
+experience, running locally without the needed for a Kubernetes cluster.
+
+For example, to run the Camel K examples, you can a Camel route written in
Kotlin directly from GitHub with:
+
+ camel run
https://github.com/apache/camel-k/blob/main/examples/languages/routes.kts
+
+### Camel JBang
+
+We continue to innovate and make running Camel quickly and easily with JBang
better and better.
+
+In this release we added support for easily enabling the following features
from the command line:
+
+- `--jfr` - To enable Java Flight Recorder that will record and save to disk
on exit.
+- `--trace` - Enables the Camel tracing logging to the console
+- `--health` - Enables health checks that are available on
`http://localhost:8080/health` endpoint.
+- `--console` - Includes the new Camel developer console (Very early
prototype, plain text mode only)
+
+We also made it easy to run using wildcards, for example to run with all files
included from current dir:
+
+ camel run *
+
+You can also run directly from GitHub via:
+
+ camel run
https://github.com/apache/camel-examples/tree/main/examples/jbang
+
+The `--reload` option has been improved, and in the next release Camel can
also do updates to Java classes.
+However, in this release the reloading is only Camel route source files.
+
+See more details at the [Camel JBang documentation](/manual/camel-jbang.html)
+
+### Developer Console
+
+This release comes with an early prototype of the new Camel Developer Console.
+The developer console is intended for development purposes, by giving relevant
+information to the developer about the running Camel application.
+
+The console is based on a pluggable architecture (similar to health-checks),
which
+makes it possible for individual components to provide their own consoles, and
also
+to make 3rd-party consoles as well.
+
+Camel will come with a set of out-of-the-box consoles, such as general
information
+about the Camel version, which components are in use, real-time metrics of the
routed
+messages, and details of the last N throw exceptions etc.
+
+We will continue to work on this functionality in the upcoming releases.
+
+We also plan to integrate with [Quarkus Dev
UI](https://quarkus.io/guides/dev-ui),
+so you will have a lot of Camel consoles when using Camel on Quarkus.
+
+### Camel UI Designer
+
+The [Camel Karavan](https://github.com/apache/camel-karavan) project is
progressing nicely, and during the development we have identified
+a number of _mistakes_ in the route model in Camel that has been improved and
corrected.
+
+This overall makes it easier to build custom Camel tooling as there are less
_model hacks_ you may need to
+implement in the tool.
+
+The changes to the model may affect users when upgrading, so make sure to read
the [upgrade guide](/manual/camel-3x-upgrade-guide-3_15.html).
+
+### Camel Kafka
+
+We refactored the commit management code to simplify the maintenance, reduce
the incidence of bugs and support the new features planned for future releases.
+
+The Kafka client was upgraded to version 3.1.0. The Kafka component remains
backwards compatible with older Kafka versions.
+
+### Quarkus
+
+The upcoming Camel Quarkus 2.8 release will be upgraded to Camel 3.15.
+
+### Spring Boot
+
+We have upgraded to the latest Spring Boot 2.6 release.
+
+### Better Java 17 support
+
+Although Java 17 is not officially supported, we did improve a few Camel
components to make them work with Java 17.
+The official support is for Java 11.
+
+### New components
+
+This release has a number of new components:
+
+- `camel-dynamic-router` - The Dynamic Router component routes exchanges to
recipients, and the recipients (and their rules) may change at runtime.
+- `camel-huaweicloud-frs` - Face Recognition Service (FRS) is an intelligent
service that uses computers to process, analyze, and understand facial images
based on human facial features.
+- `camel-knative` - Send and receive events from Knative.
+- `camel-milo` - Connect to OPC UA servers using the binary protocol for
browsing the node tree.
+- `camel-cloudevents` - Camel support for the CloudEvents specification
+- `camel-jsh-dsl` - Camel DSL with JavaShell
+
+## Upgrading
+
+Make sure to read the [upgrade
guide](/manual/camel-3x-upgrade-guide-3_15.html) if you are upgrading from a
previous Camel version.
+
+## Release Notes

+You can find more information about this release in the with a list of JIRA
tickets resolved in the release:
