Using Subversion
Subversion is an open source version control system.
In addition to the standard version control system functions described in Using Common Functions, you can select Tools > Subversion > Describe to display commit log messages for a revision.
By default, you are prompted to confirm that you want to submit changes. To suppress the prompt, select Edit > Preferences > Version Control > Subversion, and then deselect the Prompt on submit check box.
To show whitespace changes in annotation views, deselect the Ignore whitespace changes in annotation check box.
You can use Git as a client for a Subversion server. For more information, see Using Git with Subversion.
