# Feature Freeze

One week before a release, the release branch goes into a state of code freeze. At this point only critical release
blocking bugs are addressed. Additional changes that are targeted for new features and capabilities will not be merged.

### Other forms of asynchronous code

This style of using `async` and `await` is relatively new in the language.

But it makes working with asynchronous code a lot easier.
