bower install error due to description length and 'main' field containing minified files

I tried to install by `bower install angular-swing --save`, but bower throws two errors:

```bower invalid-meta The "description" is too long, the limit is 140 characters```
```bower invalid-meta The "main" field cannot contain minified files```
The specification for `bower.json` files is here https://github.com/bower/spec/blob/master/json.md
The requirements might have been changed just recently, thought I'm not sure as I'm fairly new to this.
