Andreas Klöber opened MRELEASE-1159 and commented
The release:branch goal of Maven Release Plugin should support customization of the commit message on the development resp. working copy branch which is used to bump its version (when {}updateWorkingCopyVersions == true{}).
Currently, only the commit message for the changes on the release branch is configurable via {}*scmBranchCommitComment*{}. Goal release:prepare supports customization of the commit message on the development branch as well via *scmDevelopmentCommitComment* but a similar property is missing with goal {}release:branch{}, effectively hard-coding it to {}"@{prefix} prepare for next development iteration"{}.
Affects: 3.1.1
