The number of changes associated with the roadmap spring-framework-6 update are significant enough to warrant a new major release:

• Migrate to spring-framework-6, which requires changing to Jakarta Enterprise Edition (Tomcat 10 and Jetty 12)
• Migrate to spring-security 6 necessitating the replacement of spring-security-oauth and spring-security-keycloak plugins
• Changing to Java 17 minimum
• Replacing our Java Advanced Imaging raster processing engine with for ImageN (mixing in JAI-Ext operators for a complete solution)
• Updating tp Wicket 10, which will require implementing our own dialogs.

We have held off making a new major release for two reasons addressed below:

• Making a new major release results in a non trivial expense for those who need to do a formal configuration management procedure before updating a major version.

  It has been fifteen years since GeoServer 2.0 was released. You should probably do a formal review more often than that. With the amount of change proposed an any feedback from your formal review process would be of benefit to the GeoServer project team.

• Aspirational goal to only update the version number when we changed the data directory compatibility.

  While change of data directory marked the boundary between GeoServer 1 and GeoServer 2. The user experience change from STRUTS to Wicket was more significantly noticed by Users.

Assuming crowdfunding appeal is successful the proposal is:

• Change from <major>.<minor>.<incremental>: 2.22-M0, 2.22-RC, 2.22.0 2.22.1

  Treating SNAPSHOT like an incremental dot release: 2.22-SNAPSHOT

  Tagging off the branch:

  2.22.x: 2.22-SNAPSHOT -- 2.22-SNAPSHOT
               \              \
               2.22-RC        2.22.0
                (tag)          (tag) 
  

• Change to <major>.<minor>.<incremental>-<qualifier>: 3.0-M0, 3.0-RC, 3.0.0 3.0.1

  Handling SNAPSHOT as a qualifier: 3.0.0-SNAPSHOT

  Tagging on the branch:

  3.0.x: 3.0.0-SNAPSHOT -- 3.0.0-RC -- 3.0.0-SNAPSHOT -- 3.0.0 -- 3.0.0-SNAPSHOT
                            (tag)                         (tag)
  

This approach is compatible with maven release plugin:

mvn --batch-mode release:update-versions -DautoVersionSubmodules=true -DdevelopmentVersion=3.0.0-RC

Data directory and configuration:

• data directory structure remains unchanged
• data object definition remains unchanged, for jdbc-config

REST API changes:

• http://localhost:8080/geoserver/rest/ - forwards to v1 below
• http://localhost:8080/geoserver/rest/v1
