 ## 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.
+
+`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.
 
-* 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).
