How can I get a list of non-beta bowlers?

When I run bower list

it includes the beta versions listed, which doesn't help if I'm trying to stay stable. Like this:

├─┬ ember#1.13.4 (latest is 2.0.0-beta.2)
│ └── jquery#1.11.3 (2.1.4 available, latest is 3.0.0-alpha1+compat)
├─┬ ember-cli-shims#0.0.3
│ └── ember#1.13.4 (latest is 2.0.0-beta.2)
├── ember-cli-test-loader#0.1.3
├─┬ ember-data#1.13.5
│ └── ember#1.13.4 (latest is 2.0.0-beta.2)
├─┬ ember-load-initializers#0.1.5
│ └── ember#1.13.4
├── ember-qunit#0.4.1
├─┬ ember-qunit-notifications#0.0.7
│ └── qunit-notifications#0.0.6
├─┬ ember-resolver#0.1.18
│ └── ember#1.13.4 (2.0.0-beta.2 available)
├── jquery#1.11.3 (latest is 3.0.0-alpha1+compat)
├── loader.js#3.2.1
└── qunit#1.18.0

      

        
        
        
      

    

Is there a convenient way to exclude beta from the list?
