variable that controls whether to use row-based or
statement-based binary logging. Added the
server options for binary logging control. See
option to mysqld to control how many seconds
the server should wait for the TCP/IP port to become free if it
cannot be opened.
A new statement,
generated by mysqlbinlog to represent
row-based events in binary log files. The statement argument, a
base 64-encoded string, is decoded by the server to determine
the data change indicated by the corresponding event.
Two new Hungarian collations are included:
ucs2_hungarian_ci. These support the correct
sort order for Hungarian vowels. However, they do not support
the correct order for sorting Hungarian consonant contractions;
we expect to fix this issue in a future release.
Added the XML functions
ExtractValue() returns the
content of a fragment of XML matching a given XPath expression.
UpdateXML() replaces the element
selected from a fragment of XML by an XPath expression supplied
by the user with a second XML fragment (also user-supplied), and
returns the modified XML. See XML Functions.
