Release Note

While the API has not been changed since the previous major release, we incremented the major version number of libqrencode to 4 because the implementation of the library has been largely changed.

This release improves the performance and memory footprints of code generation.

Now you can build libqrencode with CMake.

If you build the test programs, please note that the required SDL version has been changed from 1.2 to 2.0.

v4.0.0-rc3

If no problems are found, we'll release the official release of version 4.0.0 with minor documents modification.
