+title: "Apache Camel 3.20 What's New"
+date: 2022-12-21

+categories: ["Releases"]
+preview: Details of what we have done in the Camel 3.20 release.
+---
+
+Apache Camel 3.20 has just been [released](/blog/2022/12/RELEASE-3.20.0/).
+
+This release introduces a set of new features and noticeable improvements that we will cover in this blog post.
+
+## Camel Core
+
+The Split EIP has been optimized to perform faster and reduced overhead when splitting by a String literal or a regular expression.
+
+When working with EIPs you may want to temporarily disable one or more EIPs. Today you have to comment out code, or remove the EIPs.
+We have now introduced the `disabled` option which you quickly can enable on EIPs to turn off.
+The Rest DSL also has the new `disabled` option to quickly turn off specific Rest endpoints/verbs.
+
+The _tracer_ now outputs message bodies that are stream caching based, so users can see the content easily.
+
+Routes can now have `prefixId` specified, which is a prefix to assign every node IDs in the route.
+This makes it easy to separate node IDs when you have many routes, or are using route templates.
+
+### Data Format DSL
+
+The Data Format DSL is a builder API that allows using type safe construction of Camel Data Formats, .
+and is exclusively available as part of the Java DSL.
+
+The DSL can be accessed directly from the `RouteBuilder` thanks to the method `dataFormat()`.
+
+### Language DSL
+
+The Language DSL is a builder API that allows using type safe construction of Camel Languages,
+and is exclusively available as part of the Java DSL.
+
+The DSL can be accessed directly from the `RouteBuilder` thanks to the method `expression()`.
+
+## Camel JBang (Camel CLI)
+
+In this release we continue the expansion of Camel CLI.
+
+Camel JBang now uses standard Maven for downloading JARs instead of using the ShrinkWrap project.
+
+We have reduced the configuration summary _logging noise_ when using Kamelets.
+
+Custom type converters are now detected by Camel JBang when downloading new JARs.
+
+Camel JBang makes using `camel-micrometer` work out of the box, by automatic
+creating a `MeterRegistry` if none is provided.
+
+When using Rest DSL with api-doc enabled, then Camel JBang will automatically download `camel-openapi-java` if needed.
+
+Camel JBang now has shell completions which can be installed with the `camel completion` command,
+to generate bash/zsh scripts.
+
+The `camel export` command now supports Gradle as build-tool instead of Maven.
+
+We have also added new commands to easily get details about:
+- metrics
+- health-checks
+- inflight messages
+- blocked messages
+- quickly check total message/failure (easily parseable in shell scripting)
+
+The `camel doc main` command shows all the _main_ option in tables.
+
+Camel JBang will now compile `csimple` languages on startup, if in use.
+
+Added `camel run --code='...'` to quickly run some Java DSL code.
+
+There is a lot more that Camel JBang can do, so make sure to read the [Camel JBang documentation](/manual/camel-jbang.html).
+It is also a good idea to run `camel --help` to list all available commands.
+
+There you can also find information on how to get JBang installed and how to install the Camel app in JBang.
+
+### Camel Open Telemetry
+
+Camel can now correct associate spans across both synchronous and asynchronous endpoints.
+
+### Camel YAML DSL
+
+The `camel-yaml-dsl` schema now includes error handler and route configuration.
+
+Fixed a bug preventing the intercept EIP to work when used in YAML DSL.
+
+### Camel Kafka
+
+Many bug fixes and smaller improvements.
+
+### New Components
+
+There are 8 new components:
+
+- `camel-etcd3` - Get, set, delete or watch keys in etcd v3 key-value store.
+- `camel-influxdb2` - Interact with InfluxDB v2, a time series database.
+- `camel-js` - Evaluates a JavaScript expression
+- `camel-kubernetes-events` - Perform operations on Kubernetes Events and get notified on Events changes
+- `camel-plc4x` - Read and write to PLC devices
+- `camel-rocketmq` Send and receive messages from RocketMQ cluster
+- `camel-swift` - Encode and decode SWIFT MT/MX messages
+- `camel-wal` - Camel WAL component for the Resume API
+
+### Spring Boot
+
+We have upgraded to the latest Spring Boot 2.7 release.
+
+The `camel-micrometer-starter` now have additional auto configuration options,
+to easily configure micrometer settings.
+
+## Upgrading
+
+Make sure to read the [upgrade guide](/manual/camel-3x-upgrade-guide-3_20.html) if you are upgrading from a previous Camel version.
+
+## Release Notes
+
+You can find more information about this release in the list of JIRA tickets resolved in the release:
+
+- [Release notes 3.20](/releases/release-3.20.0/)
+
+## Camel 4 is coming
+
+A new major version of Camel is planned for the first half of 2023 with a bunch of amazing main goals such as the support of Spring 6, Spring Boot 3, and Quarkus 3.
+It will be proposed as a major version due to the Jakarta migration that brings breaking changes.
+
+Regarding Camel 3, we still plan to release LTS versions twice a year, but be aware that most of our efforts will be focused on Camel 4, so don't expect too many improvements and features inside.
+
+For more information about Camel 4 and the future of Camel 3, stay tuned, a dedicated blog post will be available soon.
