9.1. Notable changes to infrastructure services
Support for Berkeley DB dynamic back end has been removed
With this release, the Berkeley DB (libdb) dynamic back end is no longer supported. The named-sdb build is no longer provided. You can use the DLZ loadable plugins for each back end, for example, sqlite3 or mysql. Those plugins are not built or shipped and have to be built from the source.
