• ALTER TABLE did not take advantage of fast alterations that might otherwise apply to the operation to be performed, if the table contained temporal columns found to be in pre-5.6.4 format (TIME,        DATETIME, and TIMESTAMP columns without support for fractional seconds precision). (Bug #72997, Bug #18985760)

• avoid_temporal_upgrade controls whether ALTER TABLE implicitly upgrades temporal columns found to be in pre-5.6.4 format.
  

• show_old_temporals controls whether SHOW CREATE TABLE output  includes comments to flag temporal columns found to be in pre-5.6.4 format.
  

• Statement digesting as done previously by the Performance Schema  is now done at the SQL level regardless of whether the Performance Schema is compiled in and is available to other aspects of server operation that could benefit from it.  Bug #18304086, Bug #20015246.
