WordPress Functions Compatibility Data

The wp_functions_compatibility check uses a generated dataset:

• includes/Vars/wp-functions-since.json

That file maps WordPress function names to the WordPress version where they were introduced (@since). The check compares those versions with the plugin's minimum supported WordPress version (Requires at least).
