MySQL Connector/C++ 8.0.12 has been released
Dear MySQL users,
MySQL Connector/C++ 8.0.12 is the second GA release version of the MySQL Connector/C++ 8.0 series.
Connector/C++ 8.0 can be used to access MySQL implementing Document Store or in a traditional way, using SQL queries. It allows writing both C++ and plain C applications using X DevAPI and X DevAPI for C. It also supports the legacy API of Connector/C++ 1.1 based on JDBC4.
To learn more about how to write applications using X DevAPI, see "X DevAPI User Guide"
For generic information on using Connector/C++ 8.0, see
https://dev.mysql.com/doc/dev/connector-cpp/
Note: For X DevAPI applications, Connector/C++ 8.0 requires MySQL Server 5.7.12 or higher with X Plugin enabled. For applications that use the legacy JDBC API, Connector/C++ 8.0 can use MySQL Server 5.5 or higher, and X Plugin is not required.
To download MySQL Connector/C++ 8.0.12, see the "Generally Available (GA) Releases" tab at

Changes in MySQL Connector/C++ 8.0.12 (2018-07-27, General Availability)
* Installation Notes
* Packaging Notes
* Security Notes
* X DevAPI Notes
* Bugs Fixed
Installation Notes
* Because the Microsoft Visual C++ 2017 Redistributable installer deletes the Microsoft Visual C++ 2015 Redistributable registry keys that identify its installation, standalone MySQL MSIs may fail to detect the Microsoft Visual C++ 2015 Redistributable if both it and the Microsoft Visual C++ 2017 Redistributable are installed. The solution is to repair the Microsoft Visual C++ 2017 Redistributable via the Windows Control Panel to recreate the registry keys needed for the runtime detection. Unlike the standalone MSIs, MySQL Installer for Windows contains a workaround for the detection problem.
Packaging Notes
* An RPM package for installing ARM 64-bit (aarch64) binaries of Connector/C++ on Oracle Linux 7 is now available in the MySQL Yum Repository and for direct download. Known Limitation for this ARM release: You must enable the Oracle Linux 7 Software Collections Repository (ol7_software_collections) to install this package, and must also adjust the libstdc++7 path. See Yum's Platform Specific Notes (http://dev.mysql.com/doc/refman/8.0/en/linux-installation-yum-repo.html#yum-install-platform-specifics) for additional details.
* Installers for Connector/C++ are now available in these formats: MSI packages (Windows); RPM packages (Linux); DMG packages (macOS).
Security Notes
* yaSSL is no longer included in Connector/C++ source distributions. wolfSSL may be used as a functionally equivalent alternative that has a GPLv2-compatible license. In addition, wolfSSL (like OpenSSL) supports the TLSv1.2 protocol, which yaSSL does not. To build Connector/C++ using wolfSSL, use the -DWITH_SSL=path_name CMake option, where path_name indicates the location of the wolfSSL sources. For more information, see Source Installation System Prerequisites (http://dev.mysql.com/doc/connector-cpp/8.0/en/connector-cpp-installation-source-prerequisites.html), and Connector/C++ Source-Configuration Options (http://dev.mysql.com/doc/connector-cpp/8.0/en/connector-cpp-source-configuration-options.html).
X DevAPI Notes
* Connector/C++ now supports NOWAIT and SKIP LOCKED lock contention modes to be used with lockExclusive() and lockShared() clauses of CRUD find/select operations (see Locking Read Concurrency with NOWAIT and SKIP LOCKED (http://dev.mysql.com/doc/refman/8.0/en/innodb-locking-reads.html#innodb-locking-reads-nowait-skip-locked)), and a default lock contention mode. The following list names the permitted constants. For each item, the first and second constants apply to X DevAPI and X DevAPI for C, respectively.
+ LockContention::DEFAULT, LOCK_CONTENTION_DEFAULT: Block the query until existing row locks are released.
+ LockContention::NOWAIT, LOCK_CONTENTION_NOWAIT: Return an error if the lock cannot be obtained immediately.
+ LockContention::SKIP_LOCKED, LOCK_CONTENTION_SKIP_LOCKED: Execute the query immediately, excluding from the query items that are locked. For X DevAPI and X DevAPI for C applications, lock mode methods accept these lock contention constants as a parameter. For X DevAPI applications, lock mode methods can be called without this parameter, as before; this is equivalent to passing a lock mode of DEFAULT.
* Connector/C++ now supports the SHA256_MEMORY authentication mechanism for connections using the X Protocol. For X DevAPI applications, SessionOption::AUTH supports the new value AuthMethod::SHA256_MEMORY. For X DevAPI for C applications, the session option MYSQLX_OPT_AUTH supports the new value MYSQLX_AUTH_SHA256_MEMORY. These new values request using the sha256_memory authentication mechanism when creating a session.
* For compliance with the Core DevAPI, these Connector/C++ changes were made:
+ getAffectedItemsCount() was moved from Result to Result_common.
+ Collection.modify(condition).arrayDelete() was removed.
+ getAffectedRowsCount() was removed. Use getAffectedItemsCount() instead.
+ getWarningCount() was renamed to getWarningsCount().
Bugs Fixed
* utf8mb4 character data was handled incorrectly. (Bug #28240202)
* Session creation had a memory leak. (Bug #27917942)
* When configuring to build Connector/C++ with the legacy connector, CMake did not account for the MYSQL_CONFIG_EXECUTABLE option. (Bug #27874173, Bug #90389)
* Improper error handling for unknown hosts when creating a session could result in unexpected application exit. (Bug #27868302)
* The mysqlx_row_fetch_one() X DevAPI for C function could fail to return for large result set exceeding the maximum packet size. Now such result sets produce an error. (Bug #27732224)
Enjoy and thanks for the support!
