Does SourceForge automatically resolve conflicts in documents made by multiple concurrent editors?

If you store your documents in CVS, Subversion, or some other SCM tool, then that tool will handle conflict resolution per its normal means. However, if you are using the Document Manager component of SourceForge, then there is no automated means within the product to prevent another user from uploading a newer version of a given document that does not contain the changes you just uploaded. To prevent this, we recommend you use the document locking feature of SourceForge to prevent others from editing a document you are editing.
