 _Go MySQL Driver_ is an implementation of Go's `database/sql/driver` interface. You only need to import the driver and can use the full [`database/sql`](https://golang.org/pkg/database/sql/) API then.

 Use `mysql` as `driverName` and a valid [DSN](#dsn-data-source-name)  as `dataSourceName`:
+
 ```go
-import "database/sql"
-import _ "github.com/go-sql-driver/mysql"
+import (
+	"database/sql"
+	"time"
+
+	_ "github.com/go-sql-driver/mysql"
+)
+
+// ...

 db, err := sql.Open("mysql", "user:password@/dbname")
+if err != nil {
+	panic(err)
+}
+// See "Important settings" section.
+db.SetConnMaxLifetime(time.Minute * 3)
+db.SetMaxOpenConns(10)
+db.SetMaxIdleConns(10)
 ```

 [Examples are available in our Wiki](https://github.com/go-sql-driver/mysql/wiki/Examples "Go-MySQL-Driver Examples").

+### Important settings
+
+`db.SetConnMaxLifetime()` is required to ensure connections are closed by the driver safely before connection is closed by MySQL server, OS, or other middlewares. Since some middlewares close idle connections by 5 minutes, we recommend timeout shorter than 5 minutes. This setting helps load balancing and changing system variables too.
+
+`db.SetMaxOpenConns()` is highly recommended to limit the number of connection used by the application. There is no recommended limit number because it depends on application and MySQL server.
+
+`db.SetMaxIdleConns()` is recommended to be set same to `db.SetMaxOpenConns()`. When it is smaller than `SetMaxOpenConns()`, connections can be opened and closed much more frequently than you expect. Idle connections can be closed by the `db.SetConnMaxLifetime()`. If you want to close idle connections more rapidly, you can use `db.SetConnMaxIdleTime()` since Go 1.15.

 The connection pool is managed by Go's database/sql package.

The read, write, and dial timeouts for each individual connection are configured with the DSN parameters [`readTimeout`](#readtimeout), [`writeTimeout`](#writetimeout), and [`timeout`](#timeout), respectively.

 ## `ColumnType` Support

 * `Get` and `Select` to go quickly from query to struct/slice

 In addition to the [godoc API documentation](http://godoc.org/github.com/jmoiron/sqlx),
-there is also some [standard documentation](http://jmoiron.github.io/sqlx/) that
+there is also some [user documentation](http://jmoiron.github.io/sqlx/) that
 explains how to use `database/sql` along with sqlx.

 ## Recent Changes

-* The [introduction](https://github.com/jmoiron/sqlx/pull/387) of `sql.ColumnType` sets the required minimum Go version to 1.8.
+1.3.0:

-* sqlx/types.JsonText has been renamed to JSONText to follow Go naming conventions.
+* `sqlx.DB.Connx(context.Context) *sqlx.Conn`
+* `sqlx.BindDriver(driverName, bindType)`
+* support for `[]map[string]interface{}` to do "batch" insertions
+* allocation & perf improvements for `sqlx.In`

-This breaks backwards compatibility, but it's in a way that is trivially fixable
-(`s/JsonText/JSONText/g`).  The `types` package is both experimental and not in
-active development currently.
+DB.Connx returns an `sqlx.Conn`, which is an `sql.Conn`-alike consistent with
+sqlx's wrapping of other types.

-* Using Go 1.6 and below with `types.JSONText` and `types.GzippedText` can be _potentially unsafe_, **especially** when used with common auto-scan sqlx idioms like `Select` and `Get`. See [golang bug #13905](https://github.com/golang/go/issues/13905).
+`BindDriver` allows users to control the bindvars that sqlx will use for drivers,
+and add new drivers at runtime.  This results in a very slight performance hit
+when resolving the driver into a bind type (~40ns per call), but it allows users
+to specify what bindtype their driver uses even when sqlx has not been updated
+to know about it by default.

 ### Backwards Compatibility

-There is no Go1-like promise of absolute stability, but I take the issue seriously
-and will maintain the library in a compatible state unless vital bugs prevent me 
-from doing so.  Since [#59](https://github.com/jmoiron/sqlx/issues/59) and 
-[#60](https://github.com/jmoiron/sqlx/issues/60) necessitated breaking behavior, 
-a wider API cleanup was done at the time of fixing.  It's possible this will happen
-in future;  if it does, a git tag will be provided for users requiring the old
-behavior to continue to use it until such a time as they can migrate.
+Compatibility with the most recent two versions of Go is a requirement for any
+new changes.  Compatibility beyond that is not guaranteed.
+
+Versioning is done with Go modules.  Breaking changes (eg. removing deprecated API)
+will get major version number bumps.
