Migrate from `javax` -> `jakarta` (JEE 10) +2. Java 17 as minimum +3. Spring Framework 6 +4. Spring Boot 3 +5. Quarkus 3 + +## Release Goals +6. Release only what is ready (JEE10 / Java17) + This means that Camel components that are not ready (yet) will be dropped in a release until they are ready. +7. Release Camel Core + Camel Spring Boot together +8. Move Camel Karaf to Apache Karaf as karaf-camel sub-project + +## Major Goals +9. Support Java 17 features such as records, multiline strings, and what else +10. EIP model without JAXB dependency (is possible) +11. Endpoint URI parsing (do not use `java.net.URI`) +12. Deprecate `message.getIn()` use `getMessage()` instead +13. Deprecate/Remove camel-cdi +14. Deprecate/Remove MDC logging (complex and buggy and does not fit modern app development) + +## Minor Goals +15. Remove MEP `InOptionalOut` (not in use) +16. Remove JUnit 4 support + +## Dropping Java 11 support + +Some users have asked whether Camel v4 can support Java 11. Because Spring Framework 6 is +requiring Java 17, then this is _tricky_ as a number of Camel components rely on Spring. + +Java 21 LTS is to be released in September 2023, meaning that Camel v4 +should be forward-facing and prepare to support Java 21 instead of 11. + +Users that must use Java 11, can use Camel v3 and then later +upgrade to Camel v4 when they are ready to upgrade Java as well. + +## Timeline + +The timelines are _estimates_ and the number of releases can vary depending on need +and how far we are in the process. In other words Camel v4 can be released sooner than +the estimates. + +- Feb 2023: Camel 4.0 milestone 1 +- Mar 2023: Camel 4.0 milestone 2 +- Apr 2023: Camel 4.0 RC1 +- May 2023: Camel 4.0 LTS (LTS until 4.1 release) +- Aug 2023: Camel 4.1 LTS (LTS until Jun 2024) +- Oct 2023: Camel 4.2 +- Dec 2023: Camel 4.3 LTS + +For Camel 3 then we slow down in releases and provide 2 LTS releases per year. Review Comment: So, to simplify it, it could rather be something more or less like: "For Camel 3, only LTS versions are released twice a year"? -- This is an automated message from the Apache Git Service.
