Features
- Commits as true atomic operations (interrupted commit operations in CVS would cause repository inconsistency or corruption).
- Renamed/copied/moved/removed files retain full revision history.
- The system maintains versioning for directories, renames, and file metadata (but not for timestamps). Users can move and/or copy entire directory-trees very quickly, while retaining full revision history.
- Versioning of symbolic links.
- Native support for binary files, with space-efficient binary-diff storage.
- Apache HTTP Server as network server, WebDAV/Delta-V for protocol. There is also an independent server process called svnserve that uses a custom protocol over TCP/IP.
- Branching as a cheap operation, independent of file size (though Subversion itself does not distinguish between a branch and a directory)
- Natively client–server, layered library design.
- Client/server protocol sends diffs in both directions.
- Costs proportional to change size, not to data size.
- Parsable output, including XML log output.
- Open source licensed — Apache License in the projected 1.7 release; prior versions use a derivative of the Apache Software License, v1.1
- Internationalized program messages.
- File locking for unmergeable files ("reserved checkouts").
- Path-based authorization.
- Language bindings for C#, PHP, Python, Perl, Ruby, and Java.
- Full MIME support — users can view or change the MIME type of each file, with the software knowing which MIME types can have their differences from previous versions shown.
- Merge tracking - Merges between branches will be tracked, this allows automatically merging between branches without telling Subversion what (doesn't) need to be merged.

Famous quotes containing the word features:
““It looks as if
Some pallid thing had squashed its features flat
And its eyes shut with overeagerness
To see what people found so interesting
In one another, and had gone to sleep
Of its own stupid lack of understanding,
Or broken its white neck of mushroom stuff
Short off, and died against the windowpane.””
—Robert Frost (1874–1963)
“These, then, will be some of the features of democracy ... it will be, in all likelihood, an agreeable, lawless, particolored commonwealth, dealing with all alike on a footing of equality, whether they be really equal or not.”
—Plato (c. 427–347 B.C.)
“All visible objects, man, are but as pasteboard masks. But in each event—in the living act, the undoubted deed—there, some unknown but still reasoning thing puts forth the mouldings of its features from behind the unreasoning mask. If man will strike, strike through the mask!”
—Herman Melville (1819–1891)
