### Bug Fixes

24-
* The 5.6 host_summary and x$host_summary views incorrectly had the column with COUNT(DISTINCT accounts.user) named unique_hosts instead of unique_users (Contributed by Jesper Wisborg Krogh)

* The 5.6 `host_summary` and `x$host_summary` views incorrectly had the column with `COUNT(DISTINCT accounts.user)` named `unique_hosts` instead of `unique_users` (Contributed by Jesper Wisborg Krogh)
29+
* Both the `format_time` and `format_bytes` took a BIGINT as input, and output VARCHAR, but BIGINT could be too small for aggregated values for the inputs. Now both functions both use TEXT as their inp
30+
* The `format_time` function displayed values in minutes incorrectly
31+
* The `sys_config` related triggers had no DEFINER clause set
