The Camel `4.0.x` is a LTS release that is supported for 1 year. + +This blog post highlights some noteworthy new features and improvements in Camel v4. + +The features are based on work since January 2023, which was the time, where we switched `main` branch +to be Camel v4 based, and our effort was focused primary on Camel v4. + +### 1) Major Goals + +The need for Camel 4 is mainly driven by Java open source projects migrating from `javax` to `jakarta` APIs +and to keep up with popular runtimes such as Spring Boot and Quarkus. + +1. Migrate from `javax` -> `jakarta` (JEE 10) +2. Java 17 as minimum +3. Spring Boot 3 +4. Quarkus 3 + +Camel 4 requires Java 17. Support for Java 21 is planned for next LTS released by end of this year. + +### 2) Dependency updates + +We have upgraded all 3rd party dependencies to their latest releases where possible. + +### 3) Performance optimizations + +We have improved the performance of the internal Camel routing engine and framework. + +You can find more details in this blog post [camel 4 performance improvements](/blog/2023/05/camel-4-performance-improvements.html). + +### 4) Camel Spring Boot + +Camel 4 is at the time of release, tested with the latest Spring Boot 3.1.2 release. + +This release also comes with our first basic (and very limited) support for Spring Boot native (AOT compilation). +See more in the [aot-basic](https://github.com/apache/camel-spring-boot-examples/tree/main/aot-basic) example. + +### 5) Camel Quarkus + +The Camel Quarkus project is working on a new release with Camel 4 support, expected later this month. +Stay tuned for their release announcements. + +### 6) Camel Main + +For users that just want to run standalone Camel, then we have `camel-main` that are constantly being improved. +The foundation in `camel-main` is reused by Camel Spring Boot, Camel Quarkus, and Camel JBang as well. + +For Camel 4 we have made it possible to easily include an embedded HTTP server with the new `camel-platform-http-main` module. +See more in the [camel-main](https://github.com/apache/camel-examples/tree/main/examples/main) example. + +### 7) Camel JBang + +A lot of improvements was put into `camel-jbang`. The `camel` CLI is now able to easily run with different Camel versions, Review Comment: were put instead of was put -- This is an automated message from the Apache Git Service.
