# What is a Community Preview Feature?

A Community Preview feature is a component of Intel® Threading Building Blocks (Intel® TBB) that is being introduced to gain early feedback from developers. Comments, questions and suggestions related to Community Preview features are encouraged and should be submitted to the forums at www.threadingbuildingblocks.org.

The key properties of a CP feature are:

- It must be explicitly enabled. It is off by default.

- It is intended to have a high quality implementation.

- There is no guarantee of future existence or compatibility.

- It may have limited or no support in tools such as correctness analyzers, profilers and debuggers.

### Caution

A CP feature is subject to change in the future. It may be removed or radically altered in future releases of the library. Changes to a CP feature do NOT require the usual deprecation and deletion process. Using a CP feature in a production code base is therefore strongly discouraged.
