I committed some bad code changes to my SVN sever using TortoiseSVN.
Now the head revision is 155, but I would like to delete the last 2 revisions so that the head revision is 153. In other words, I would like to "undo" my last two commits.
How can I do this using TortoiseSVN? Does an option exist in the TortoiseSVN menu, or do I need to use the command line?
