Preview features
****************

A preview feature is a component of oneTBB introduced to receive early feedback from
users.

The key properties of a preview feature are:

- It is off by default and must be explicitly enabled.
- 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 preview feature is subject to change in future. It might be removed or significantly
    altered in future releases. Changes to a preview feature do NOT require
    usual deprecation and removal process. Therefore, using preview features in production code
    is strongly discouraged.
