How can i extract the author of a change which has triggered a bamboo plan into a variable

[Joseph]

In Bamboo

I would like to have a variable that refers to the author of the change that triggered the plan to execute.

My SCM is Subversion.

I've checked https://confluence.atlassian.com/display/BAMBOO/Bamboo+variables

however these is no reference to obtaining the change details (e..g. Author, commit message, version etc)

Joseph, at the moment we do not provide variables that would be substituted with change details. You can raise feature requests for this using our public issue tracker.
