Incompatible Change; Important Change: The
FEDERATEDstorage engine is now disabled by default in the
.cnffiles shipped with MySQL distributions (
my-medium.cnf, and so forth). This affects server behavior only if you install one of these files. (Bug #37069)
References: See also Bug #32575.
On Windows 64-bit systems, temporary variables of
longtypes were used to store
ulongvalues, causing key cache initialization to receive distorted parameters. The effect was that setting
key_buffer_sizeto values of 2GB or more caused memory exhaustion to due allocation of too much memory. (Bug #36705)
UPDATEstatements that used a temporary table could fail to update all qualifying rows or fail with a spurious duplicate-key error. (Bug #36676)
EXPLAIN EXTENDED, execution of an uncorrelated
INsubquery caused a crash if the subquery required a temporary table for its execution. (Bug #36011)
