v0.10.0

New features in v0.10.0

• Add cfn-flow update to update existing stacks. 🎉 This allows more flexibility modify stateful backing resources with cfn-flow. ⚠️ Note that updating stacks conflicts with the idea of immutable infrastructure, so it's intended to be used sparingly. Added in #17.
• Show stack outputs when deploying or updating stacks. #16. 🙆‍♀️
• cfn-flow delete now polls for stack events instead of exiting before the stack is fully deleted. #18 😌

v0.9.0

v0.9.0 adds the ability to reference another stack's output as input parameters in cfn-flow.yml. This is useful to easily include values from backing templates in your deployments. See #14.
