   At this point, build each project (`mvn clean install -Pfastinstall`) and check for generated changes that should be committed.
   
   NOTE: TODO: Is there a step of setting up CI or the regen bot?
   Should maven snapshots be deployed?

  +=== Changes to other subprojects
  +
  +Be sure the subprojects using the latest release of main camel are aware that they need to update to the latest version, including documentation updates.
  +Any reference to the main camel documentation should use a version set in the subproject antora.yml component descriptor(s).
  +This may be set automatically from another source such as a maven `pom.xml`.
  +
  +Subproject changes are likely to involve code as well as documentation changes and need to be done by a subproject expert.
  +This section only attempts to describe the documentation changes needed.
   
   In the `camel-quarkus` project examine the root `pom.xml` of every version used in the website.
   There will be a property entry like:
  
positive.code: In `camel-spring-boot/docs/components/antora.yml`::
  In `camel-spring-boot/docs/spring-boot/antora.yml`::
  
  * Change `version` to the branch name e.g. `3.12.x`
  * Remove the `prerelease` flag line
  * If the new branch is LTS, set the display-version to e.g. `3.12.x (LTS)`.
  * If the new branch is not LTS, remove the `display-version` line.
  
  In `camel-karaf:tooling/camel-karaf-docs-maven-plugin/src/main/java/org/apache/camel/karaf/maven/ExtMvelHelper.java`::
  
negative.code: == After a new release branch is created
  
  This will always be a branch from `main`.
  Changes to the new branch, say `camel-3.13.x`, will be needed.
  The changes are almost the same whether the new branch is LTS or not.
  
  === Changes to the new branch (`3.13.x`) in synchronized projects
  
  For each of the projects, `camel`, `camel-karaf`, `camel-spring-boot`, locate the section for the project in the `camel-website` `antora-playbook.yml` and adjust the version in the component descriptor for each start path.
