ScyllaDB release: version 1.1.2

ScyllaDB 1.1.2, released by the ScyllaDB team on June 9, 2016, is a bugfix update for the ScyllaDB 1.1 stable branch, ensuring backward compatibility and supporting rolling upgrades. The release addresses several issues, including fixing a network interrupt pinning error in scylla_setup that was leading to performance degradation in ScyllaDB AMI, and reducing memory usage during data streaming between nodes, which previously resulted in error messages related to memory allocation. The update emphasizes improvements in system performance and stability, with contributions from team members Asias He and Pekka Enberg, and provides links for users to get started with the new version, upgrade from previous versions, and report any problems encountered.
