+Breaking: #88741 - cHash calculation in indexed search removed
+==============================================================
+
+See :issue:`88741`
+
+Description
+===========
+
+When indexing a page, the indexer of `Indexed search` previously kept the used cHash and the
+used "cHashParams" for storing search entries. This is not necessary anymore, as Site Handling now
+contains the relevant arguments already in the search entry as well. This can be removed now.
+
+In addition, when setting up an Indexing configuration, the option to respect cHash is removed,
+as this is done automatically when needed.
+
+The public property :php:`TYPO3\CMS\IndexedSearch\Indexer->cHashParams` has been removed.
+
+The sixth method argument of :php:`TYPO3\CMS\IndexedSearch\Indexer->backend_initIndexer()`
+has been removed.
+
+The following database fields are unused and have been removed:
+
+* :sql:`index_config.chashcalc`
+* :sql:`index_phash.cHashParams`
+
+The database field :sql:`index_debug.debuginfo` now contains data stored in a JSON-formatted string
+instead of a serialized PHP string.
+
+
+Impact
+======
+
+Manual database queries accessing the database fields will result in SQL errors.
+
+In addition, accessing the removed property or using the sixth argument of the changed public method
+will have no effect anymore.
+
+
+Affected Installations
+======================
+
+TYPO3 installations using Indexed Search and custom configuration or extending functionality
+of Indexed Search.
+
+
+Migration
+=========
+
+No migration needed, as everything works as before. The data is now stored in
+the database field as JSON-encoded string `index_phash.static_page_arguments`.
+
+In case of using debug information for Indexed Search (index with enabled debug information),
+where data was previously stored in `index_debug.debuginfo` as serialized PHP string,
+indexing needs to be rebuilt, but only to render the debug information properly in the TYPO3 Backend
+module. If debug information is not enabled, re-indexing is not necessary.
