## 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
