TWAIN DSM v2.5
This is release 2.5.0 of the TWAIN Data Source Manager. There haven't been any code changes, they've just been rebuilt to update their version numbers. In this case tracking to version 2.5 of the TWAIN Specification.
Releases accompany updates to the TWAIN Specification, even when there are no actual code changes in the DSM. We do this to reduce confusion even though all DSMs must interoperate with any application or data source, regardless of their supported TWAIN Protocol.
