The implementation of condition variables specific to Windows XP and Windows Server 2003 was removed from the source code because MySQL is not supported on those platforms as of MySQL 5.6.Note
This change has the following implication: Previously, Connector/C 6.1, while not officially supported on Windows XP or Windows Server 2003, could be used on those platforms. This is no longer possible.
Static libraries built with VS2008, VS2010, VS2012 are now distributed as part of Connector/C packages for Windows: ZIP and MSI. New directories named
vs11located under the
libdirectory contain static libraries and corresponding pdb files built with VS2008, VS2010, and VS2012, respectively.
MySQL now supports the use of protocol trace plugins: client-side plugins that implement tracing of communication between a client and the server that takes place using the client/server protocol. Protocol trace plugins use the client plugin API.
In MySQL source distributions, a test protocol trace plugin is implemented in the
test_trace_plugin.ccfile in the
libmysqldirectory. This can be examined as a guide to writing other protocol trace plugins.
CLIENT_CONNECT_WITH_DBflag was improperly handled in the C client library. This could lead to a malformed packet sent to the server. (Bug #17351732)
mysql_real_connect()C API function could leak memory if it failed. (Bug #17337684)
mysql_options()C API function could leak memory if called more than once with the
MYSQL_SET_CLIENT_IPoption. (Bug #17297012)
The Connector/C RPM package was missing the following files:
perror. (Bug #17261610)
The Connector/C MSI package was missing the following files:
INFO_BIN. (Bug #17261526)
On Windows, a MySQL client program that simply used
#include <mysql.h>could not be compiled due to missing Windows declarations in that file. The same program would compile on other platforms. (Bug #16409270)

libmysql.dlllibrary was missing several symbols:
mysql_plugin_options. (Bug #69204, Bug #16797982)
