| 5 | Tedious is a pure-Javascript implementation of the [TDS protocol](http://msdn.microsoft.com/en-us/library/dd304523.aspx),
|
| 6 | which is used to interact with instances of Microsoft's SQL Server. It is intended to be a fairly slim implementation of the protocol, with not too much additional functionality.
|

|
| 8 | **NOTE: New columns are nullable by default as of version 1.11.0**
|
| 9 |
|
| 10 | Previous behavior can be restored using `config.options.enableAnsiNullDefault = false`. See [pull request 230](https://github.com/tediousjs/tedious/pull/230).
|

|
| 12 | **NOTE: Default login behavior has changed slightly as of version 1.2**
