Tableau Release Notes
Tableau Public has become the gathering point for many of the best-respected, most influential and most creative members of the data community. This means that the visualisations found in Tableau Public also include the highest tier of creativity and quality. With the new Hire Me button, we are better enabling authors to indicate that they are available for work and customers to see which authors are available to hire.
