+=======================================================
+Important: #84105 - Streamline deprecation log handling
+=======================================================
+
+See :issue:`84105`
+
+Description
+===========
+
+TYPO3 now comes with default configuration, in which deprecation logging is disabled.
+This means if you update to the latest TYPO3 version, you need to change your development
+configuration to enable deprecation logging in case you need it.
+
+Enabling the deprecation log can be done in Install Tool. Navigate to "Settings",
+click on "Choose Preset" in "Configuration Presets" pane, open "Debug Settings", select "Debug"
+and submit with "Activate preset".
+Disabling deprecation log can be done by selecting the "Live" preset instead.
+
+Please note, that these steps only enable/disable the FileWriter, which comes with TYPO3 default configuration.
+If you manually configured **additional** writers for the `TYPO3.CMS.deprecations` logger, you need to manually remove
+them to completely disable deprecation logging.
+
+This is how the LOG section in :file:`LocalConfiguration.php` looks like with disabled deprecation logging:
+
+.. code-block:: php
+
+ 'LOG' => [
+ 'TYPO3' => [
+ 'CMS' => [
+ 'deprecations' => [
+ 'writerConfiguration' => [
+ \TYPO3\CMS\Core\Log\LogLevel::NOTICE => [
+ \TYPO3\CMS\Core\Log\Writer\FileWriter::class => [
+ 'disabled' => true,
+ ],
+ ],
+ ],
+ ],
+ ],
+ ],
+ ],
+
+Any other log writer can be disabled as well, by providing a `disabled` option with a truthy value.
