LSB 5.0

The LSB workgroup is happy to announce the release of LSB 5.0, including specifications, development tools, and tests.

This release is dedicated to the memory of Christopher Yeoh, a long-time friend and colleague, and a contributor to LSB from the earliest days. Without his dedication this work would not have been possible.
