D.1.2. Changes in MySQL 5.5.17 (19 October 2011)
------------------------------------------------


*Functionality Added or Changed*

* *Replication*: Previously, replication slaves could connect to the
master server only through master accounts that use native
authentication. Now replication slaves can also connect through
master accounts that use nonnative authentication if the required
client-side plugin is installed on the slave side in the directory
named by the slave `plugin_dir' system variable. (Bug #12897501)

* *Note `MEMORY': memory-storage-engine. table creation time is now
available in the `CREATE_TIME' column of the *Note
`INFORMATION_SCHEMA.TABLES': tables-table. table and the
`Create_time' column of *Note `SHOW TABLE STATUS':
show-table-status. output. (Bug #51655, Bug #11759349)

*Bugs Fixed*

* *InnoDB Storage Engine*: This fix improves the performance of
instrumentation code for `InnoDB' buffer pool operations. (Bug
#12950803, Bug #62294)

* *InnoDB Storage Engine*: Data from BLOB columns could be lost if
the server crashed at a precise moment when other columns were
being updated in an `InnoDB' table. (Bug #12704861)

* *InnoDB Storage Engine*: Lookups using secondary indexes could
give incorrect matches under a specific set of conditions. The
conditions involve an index defined on a column prefix, for a BLOB
or other long column stored outside the index page, with a table
using the Barracuda file format. (Bug #12601439)

* *InnoDB Storage Engine*: This fix corrects cases where the MySQL
server could hang or abort with a `long semaphore wait' message.
(This is a different issue than when these symptoms occurred
during a *Note `CHECK TABLE': check-table. statement.) (Bug
#11766591, Bug #59733)

* Internal conversion of zero to binary and back could yield a
result with incorrect precision. (Bug #12911710)

* Valgrind warnings generated by `filesort' operations were fixed.
(Bug #12856915)

* *Note `mysqld_safe': mysqld-safe. did not properly check for an
already running instance of *Note `mysqld': mysqld. (Bug
#11878394)

* The help message for *Note `mysql_install_db': mysql-install-db.
did not indicate that it supports the `--defaults-file',
`--defaults-extra-file' and `--no-defaults' options. (Bug #58898,
Bug #11765888)

* An assertion designed to detect zero-length sort keys also was
raised when the entire key set fit in memory. (Bug #58200, Bug
#11765254)

* *Note `myisampack': myisampack. could create corrupt `FULLTEXT'
indexes when compressing tables. (Bug #53646, Bug #11761180)

* A linking problem prevented the *Note `FEDERATED':
federated-storage-engine. storage engine plugin from loading.
(Bug #40942, Bug #11750417)
