What is is it in yet?

"Is it in yet?" is a common phrase used, often humorously, to ask if a software feature, game, or other project has reached a specific stage of completion or integration. It essentially inquires about whether something has been implemented, merged into a codebase, or has become available to users. The phrase often carries an expectation of impatience or anticipation, particularly in software development environments. It can also be used in a playful manner to inquire about the release or availability of a product.
