- switchover top: added `Conns` column which stands for `Established connections to tarantool (taken from box.stat.net().CONNECTIONS.current` - switchover top: `Cur` was renamed to `Reqs` (stands for network requests per second). - github.com/ochaton/background was imported to switchover. All meaningfull background fibers were rewritten using background library - switchover restart-replication (rr) now behaves in the same way as package-reload (pr). rr also supports --cluster and --shard flags. - Fixed fiber leaks and eval flood during `switchover watch`. - Sockets to unconnected tarantools now closed after discovery timeout exhausted. - Nothing was removed - No security changes were introdusced.
