News from the ChangeLog:
Functionality added or changed:
* Added the XML functions ExtractValue() and UpdateXML().
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 Section 12.9, "XML Functions."
* Added the --base64-output option to mysqlbinlog to print all binary
log entries using base64 encoding. This is for debugging only. Logs
produced using this option should not be applied on production
* Added the --port-open-timeout 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. (Bug #15591 (http://bugs.mysql.com/15591))
* Two new Hungarian collations are included: utf8_hungarian_ci and
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; this issue will be fixed
in a future release.
* Plugins can now have status variables, that are shown in SHOW
* InnoDB: Comparison of indexed VARCHAR CHARACTER SET ucs2 COLLATE
ucs2_bin columns using LIKE could fail.
(Bug #14583 (http://bugs.mysql.com/14583))
* Creating a trigger caused a server crash if the table or trigger
database was not known because no default database had been
selected. (Bug #14863 (http://bugs.mysql.com/14863))
* Issuing a DROP USER command could cause some users to encounter a
hostname is not allowed to connect to this MySQL server error.
(Bug #15775 (http://bugs.mysql.com/15775))
* The --plugin_dir option was not working. Also fix error with
specifying parser name for fulltext.
(Bug #16068 (http://bugs.mysql.com/16068))
* Attempting to insert into a table partitioned by LIST a value less
than any specified in one of the table's partition definitions
resulted in a server crash. In such cases, mysqld now returns ERROR
1500 (HY000): Table has no partition for value v , where v is the
out-of-range value. (Bug #15819 (http://bugs.mysql.com/15819))
* The Windows package, "mysql-noinstall-5.1.5-alpha-win32.zip",
contains just the "mysqld-max.exe" and "mysqld-max-nt.exe" binaries;
because "mysqld.exe", "mysqld-nt.exe", and "mysqld-debug.exe" have
not been built for this version. If you previously used one of the
latter binaries, you may need to adapt your settings.
