Currently there are two supported baselines of Remoting.
Remoting 3 is a new baseline introduced in Jenkins 2.27.
Major changes:
- Java 7 is a new target JVM, the new remoting version is not guaranteed to work properly on Java 9 and versions below Java 7
- New JNLP4-connect protocol, which improves performance and stability compared to the JNLP3 protocol
Remoting 3 does not have full binary compatibity with Remoting 2 (see Remoting 3 Compatibility Notes).
Remoting 2 is a deprecated version, which was used in Jenkins till the 2.27 release.
It is not being offered in new releases of Jenkins.
This version is still being maintained, because it is being used in Jenkins LTS and several other projects.
Maintenance approach:
- The branch reached its End of Life on May 01, 2017.
- Changes may be backported and released upon request. See the Contributing Page.
- New releases may include bugfixes, security fixes and performance enhancements
- There is no plans to introduce new features in Remoting 2.x
Changelogs for Remoting 2.x releases are available here.
