OpenSTV version 1.3 is now available. Select "Download OpenSTV" from the top of this page to get download links.

The most significant changes in this release are the following:

• Redesigned OpenSTV user interface: (1) User can only run an election from a saved ballot file (previously, you could use a ballot file in memory). (2) User can edit/create ballots in a separate Ballot File Editor window and save them to a file.
• Can save election results in HTML.
• More explanatory output for Condorcet elections.
• Added subclasses for different ballot types to make it easier to support new types.
• Changes under the hood that make OpenSTV easier to maintain.
