Upgrade Notes
*************

* The default value of "max_overflow" config option has been
  increased from 10 to 50 in order to allow OpenStack services heavily
  using DBs to better handle spikes of concurrent requests and lower
  the probability of getting a pool timeout issue.

  This change potentially leads to increasing of the number of open
  connections to an RDBMS server. Depending on the configuration, you
  may see "too many connections" errors in logs of OpenStack services
  / RDBMS server. The max limit of connections can be set by the means
  of these config options:

  http://dev.mysql.com/doc/refman/5.7/en/server-system-
  variables.html#sysvar_max_connections
  http://www.postgresql.org/docs/current/static/runtime-config-
  connection.html#GUC-MAX-CONNECTIONS
