The H-Store project is pleased to announce the release of the freshest and most dope version of its transaction processing database management system. The major enhancements in the system are related to anti-caching<\/a> and recovery. We have also begun exploring how to port H-Store to work on non-volatile memory<\/a> storage devices.<\/p>\n
