+=============================================
+Deprecation: #99633 - GeneralUtility::_POST()
+=============================================
+
+See :issue:`99633`
+
+Description
+===========
+
+The method :php:`\TYPO3\CMS\Core\Utility\GeneralUtility::_POST()` has
+been marked deprecated and should not be used any longer.
+
+Modern code should access GET and POST data from the PSR-7
+:php:`\Psr\Http\Message\ServerRequestInterface`, and should avoid accessing
+super-globals :php:`$_GET` and :php:`$_POST`
+directly. This will avoid future side-effects when using sub-requests. Some
+:php:`GeneralUtility` related helper methods like :php:`_POST()` violate this,
+using them is considered a technical debt. They are being phased out.
+
+
+Impact
+======
+
+Calling the method from PHP code will trigger a PHP deprecation notice.
+
+
+Affected installations
+======================
+
+TYPO3 installations with third-party extensions using :php:`GeneralUtility::_POST()`
+are affected. This typically occurs in TYPO3 installations which
+have been migrated to latest TYPO3 Core versions and
+haven't been adapted properly yet.
+
+The extension scanner will find usages with a strong match.
+
+
+Migration
+=========
+
+:php:`GeneralUtility::_POST()` is a helper method that retrieves
+incoming HTTP body parameters / `POST` parameters and returns the value.
+
+The same result can be achieved by retrieving arguments from the request object.
+An instance of the PSR-7 :php:`ServerRequestInterface` is handed over to
+controllers by TYPO3 Core's PSR-15 :php:`\TYPO3\CMS\Core\Http\RequestHandlerInterface`
+and middleware implementations, and is available in various related scopes
+like the frontend :php:`\TYPO3\CMS\Frontend\ContentObject\ContentObjectRenderer`.
+
+Typical code:
+
+..  code-block:: php
+
+    use TYPO3\CMS\Core\Utility\GeneralUtility;
+
+    // Before
+    $value = GeneralUtility::_POST('tx_scheduler');
+
+    // After
+    $value = $request->getParsedBody()['tx_scheduler']);
