-Deprecation: #85821 - boostrap methods
-======================================
-
-See :issue:`85821`
-
-Description
-===========
-
-The following methods of :php:`TYPO3\CMS\Core\Core\Boostrap` have been marked as deprecated. Some of
-them will just change their visibility from public to protected in TYPO3 v10 and thus should not
-be called externally any longer:
-
-* :php:`TYPO3\CMS\Core\Core\Boostrap::usesComposerClassLoading()`
-* :php:`TYPO3\CMS\Core\Core\Boostrap::getInstance()`
-* :php:`TYPO3\CMS\Core\Core\Boostrap->configure()`
-* :php:`TYPO3\CMS\Core\Core\Boostrap::checkIfEssentialConfigurationExists()`
-* :php:`TYPO3\CMS\Core\Core\Boostrap->setEarlyInstance()`
-* :php:`TYPO3\CMS\Core\Core\Boostrap->getEarlyInstance()`
-* :php:`TYPO3\CMS\Core\Core\Boostrap->getEarlyInstances()`
-* :php:`TYPO3\CMS\Core\Core\Boostrap::loadConfigurationAndInitialize()`
-* :php:`TYPO3\CMS\Core\Core\Boostrap->initializePackageManagement()`
-* :php:`TYPO3\CMS\Core\Core\Boostrap::populateLocalConfiguration()`
-* :php:`TYPO3\CMS\Core\Core\Boostrap::disableCoreCache()`
-* :php:`TYPO3\CMS\Core\Core\Boostrap::initializeCachingFramework()`
-* :php:`TYPO3\CMS\Core\Core\Boostrap->setRequestType()`
-* :php:`TYPO3\CMS\Core\Core\Boostrap::setFinalCachingFrameworkCacheConfiguration()`
-
-
-Impact
-======
-
-This deprecation is only interesting for code that interferes with early core boostrap.
-Those may trigger PHP :php:`E_USER_DEPRECATED` error.
-
-
-Affected Installations
-======================
-
-Instances using early boostrap code may be affected by this. Those should strive for
-using the general entry method :php:`Bootstrap::init()` instead.
-
-
-Migration
-=========
-
-See changes on the typo3/testing-framework which formerly used early instance
-bootstrap calls for an example on how existing code can be refactored to use
-the top level :php:`Bootstrap::init()` instead.
