96 ## Version 1.2 (2014-06-03)
100 - We switched back to a "rolling release". `go get` installs the current master branch again
101 - Version v1 of the driver will not be maintained anymore. Go 1.0 is no longer supported by this driver
102 - Exported errors to allow easy checking from application code
103 - Enabled TCP Keepalives on TCP connections
104 - Optimized INFILE handling (better buffer size calculation, lazy init, ...)
105 - The DSN parser also checks for a missing separating slash
106 - Faster binary date / datetime to string formatting
107 - Also exported the MySQLWarning type
108 - mysqlConn.Close returns the first error encountered instead of ignoring all errors
109 - writePacket() automatically writes the packet size to the header
110 - readPacket() uses an iterative approach instead of the recursive approach to merge splitted packets
114 - `RegisterDial` allows the usage of a custom dial function to establish the network connection
115 - Setting the connection collation is possible with the `collation` DSN parameter. This parameter should be preferred over the `charset` parameter
116 - Logging of critical errors is configurable with `SetLogger`
117 - Google CloudSQL support
121 - Allow more than 32 parameters in prepared statements
122 - Various old_password fixes
123 - Fixed TestConcurrent test to pass Go's race detection
124 - Fixed appendLengthEncodedInteger for large numbers
125 - Renamed readLengthEnodedString to readLengthEncodedString and skipLengthEnodedString to skipLengthEncodedString (fixed typo)
128 ## Version 1.1 (2013-11-02)
132 - Go-MySQL-Driver now requires Go 1.1
133 - Connections now use the collation `utf8_general_ci` by default. Adding `&charset=UTF8` to the DSN should not be necessary anymore
134 - Made closing rows and connections error tolerant. This allows for example deferring rows.Close() without checking for errors
135 - `[]byte(nil)` is now treated as a NULL value. Before, it was treated like an empty string / `[]byte("")`
136 - DSN parameter values must now be url.QueryEscape'ed. This allows text values to contain special characters, such as '&'.
137 - Use the IO buffer also for writing. This results in zero allocations (by the driver) for most queries
138 - Optimized the buffer for reading
139 - stmt.Query now caches column metadata
141 - Changed the copyright header to include all contributors
142 - Improved the LOAD INFILE documentation
143 - The driver struct is now exported to make the driver directly accessible
144 - Refactored the driver tests
145 - Added more benchmarks and moved all to a separate file
146 - Other small refactoring
150 - Added *old_passwords* support: Required in some cases, but must be enabled by adding `allowOldPasswords=true` to the DSN since it is insecure
151 - Added a `clientFoundRows` parameter: Return the number of matching rows instead of the number of rows changed on UPDATEs
152 - Added TLS/SSL support: Use a TLS/SSL encrypted connection to the server. Custom TLS configs can be registered and used
156 - Fixed MySQL 4.1 support: MySQL 4.1 sends packets with lengths which differ from the specification
157 - Convert to DB timezone when inserting `time.Time`
158 - Splitted packets (more than 16MB) are now merged correctly
159 - Fixed false positive `io.EOF` errors when the data was fully read
160 - Avoid panics on reuse of closed connections
161 - Fixed empty string producing false nil values
162 - Fixed sign byte for positive TIME fields
