Committing

When you have completed your edits for an item, you can select Commit or Add and Commit to take this item out of the locked state and to save the current state of this item in the repository. This is equivalent to checking in the item.

Commit serves for storing a new version of an existing item (that is already under version control) in the Subversion repository.
Add and Commit brings the selected item under version control and commits it to the Subversion repository in a single operation.
