Version 1.2 (2014-06-03)

Changes:

• We switched back to a "rolling release". go get installs the current master branch again
• Version v1 of the driver will not be maintained anymore. Go 1.0 is no longer supported by this driver
• Exported errors to allow easy checking from application code
• Enabled TCP Keepalives on TCP connections
• Optimized INFILE handling (better buffer size calculation, lazy init, ...)
• The DSN parser also checks for a missing separating slash
• Faster binary date / datetime to string formatting
• Also exported the MySQLWarning type
• mysqlConn.Close returns the first error encountered instead of ignoring all errors
• writePacket() automatically writes the packet size to the header
• readPacket() uses an iterative approach instead of the recursive approach to merge splitted packets

New Features:

• RegisterDial allows the usage of a custom dial function to establish the network connection
• Setting the connection collation is possible with the collation DSN parameter. This parameter should be preferred over the charset parameter
• Logging of critical errors is configurable with SetLogger
• Google CloudSQL support

Bugfixes:

• Allow more than 32 parameters in prepared statements
• Various old_password fixes
• Fixed TestConcurrent test to pass Go's race detection
• Fixed appendLengthEncodedInteger for large numbers
• Renamed readLengthEnodedString to readLengthEncodedString and skipLengthEnodedString to skipLengthEncodedString (fixed typo)

Version 1.1 (2013-11-02)

Changes:

• Go-MySQL-Driver now requires Go 1.1
• Connections now use the collation utf8_general_ci by default. Adding &charset=UTF8 to the DSN should not be necessary anymore
• Made closing rows and connections error tolerant. This allows for example deferring rows.Close() without checking for errors
• []byte(nil) is now treated as a NULL value. Before, it was treated like an empty string / []byte("")
• DSN parameter values must now be url.QueryEscape'ed. This allows text values to contain special characters, such as '&'.
• Use the IO buffer also for writing. This results in zero allocations (by the driver) for most queries
• Optimized the buffer for reading
• stmt.Query now caches column metadata
• New Logo
• Changed the copyright header to include all contributors
• Improved the LOAD INFILE documentation
• The driver struct is now exported to make the driver directly accessible
• Refactored the driver tests
• Added more benchmarks and moved all to a separate file
• Other small refactoring

New Features:

• Added old_passwords support: Required in some cases, but must be enabled by adding allowOldPasswords=true to the DSN since it is insecure
• Added a clientFoundRows parameter: Return the number of matching rows instead of the number of rows changed on UPDATEs
• Added TLS/SSL support: Use a TLS/SSL encrypted connection to the server. Custom TLS configs can be registered and used

Bugfixes:

• Fixed MySQL 4.1 support: MySQL 4.1 sends packets with lengths which differ from the specification
• Convert to DB timezone when inserting time.Time
• Splitted packets (more than 16MB) are now merged correctly
• Fixed false positive io.EOF errors when the data was fully read
• Avoid panics on reuse of closed connections
• Fixed empty string producing false nil values
• Fixed sign byte for positive TIME fields

Version 1.0 (2013-05-14)

Initial Release
