Version 0.19 of SoCo is now feature frozen which means that it will enter a 2 week testing period before release. If someone wants to contribute to SoCo testing is a great way. You can contribute to testing in 2 ways.
2) Test that your SoCo application works with version 0.19
Development continues in the main git branch, so all testing should happen against the 0.19 branch. If you are in doubt about how to checkout, test, run and/or install this testing branch, ask a question here or in the Gitter channel:
