All major and minor releases are briefly explained below.

For richer information consult the commit log on github with referenced pull requests.

We do not include break-fix version release in this file.

### v2.2.0
- [Add support for excapeLiteral and escapeIdentifier in both JavaScript and the native bindings](https://github.com/brianc/node-postgres/pull/396)

### v2.1.0
- Add support for SSL connections in JavaScript driver
 - this means you can connect to heroku postgres from your local machine without the native bindings!
- [Add field metadata to result object](https://github.com/brianc/node-postgres/blob/master/test/integration/client/row-description-on-results-tests.js)
- [Add ability for rows to be returned as arrays instead of objects](https://github.com/brianc/node-postgres/blob/master/test/integration/client/results-as-array-tests.js)

### v2.0.0

- Properly handle various PostgreSQL to JavaScript type conversions to avoid data loss:

```
PostgreSQL | pg@v2.0 JavaScript | pg@v1.0 JavaScript
--------------------------------|----------------
float4     | number (float)     | string
float8     | number (float)     | string
int8       | string             | number (int)
numeric    | string             | number (float)
decimal    | string             | number (float)
```

If you are unhappy with these changes you can always [override the built in type parsing fairly easily](https://github.com/brianc/node-pg-parse-float).
