+============================================================
+Documentation of breaking changes, deprecations and features
+============================================================
+
+
+Motivation and goals
+====================
+
+Spreading information about important core changes has been a problematic issue ever since. With the switch to the
+new release cycle with version 7 of the TYPO3 CMS core this situation should be improved.
+
+A dedicated changelog of important changes is established to inform users, developers and other core related
+teams or projects:
+
+ - Overview for documentation team which changes trigger documentation changes.
+
+ - Overview for Release Managers and other "Spread the word" related works on important changes.
+
+ - Hints for extension developers, integrators and project developers whose own code areas may need adjustments on core updates.
+
+ - Standardized format for easy usage in scripts like a core migration or release notes system.
+
+This new structure also replaces the NEWS.md file.
+
+Different changelog types
+=========================
+
+A changelog handles one of these change types:
+
+ - Breaking change: A patch moved or removed a specific part of core functionality that may break extensions if they use this part. Removal of deprecated code or an interface change are good examples of this type.
+
+ - Deprecation: A patch deprecates a certain core functionality for a planned removal.
+
+ - Feature: A patch adds new functionality.
+
+Casual bug fixes do not need changelog files, but every change that may be of special interest for extension developers
+or documentation writers should receive an entry. The changelog file must be provided as part of the patch that
+introduces the change.
+
+
+Location
+========
+
+New changelog files should be added to the "master" directory. If a version is to be released, all files in this directory
+will be moved to a directory that is named after the release number. This way it can be easily seen which change was
+introduced in which released core version.
+
+
+Filename convention
+===================
+
+<type>-<forgeIssueNumber>-<UpperCamelCaseDescription>.rst
+
+
+File content
+============
+
+Like other documentation, changelog files are done in ReST, see `TYPO3 wiki ReST syntax`_ for more details.
+
+ - All types contain a "Description" section that should give a short summary on which core part was affected by the change.
+
+ - All types contain an "Impact" section that describes the possible impact of a change. An example is "Frontend output may change", "Configuration of xy is easier" or "Backend will throw a fatal error".
+
+ - Types "Deprecation" and "Breaking" contain an "Affected installations" section that describes when and if a TYPO3 instance is affected by a change. Example: "Extension xy is in use" or "TypoScript functionality xy is used" or "System is based on PHP 5.3".
+
+ - Types "Deprecation" and "Breaking" contain a "Migration" section to describe best practices on how to cope with a specific change.

+============================================================
+Breaking: #42543 - Default TypoScript Removed
+============================================================
+
+Description
+===========
+
+The default TypoScript :ts:`styles.insertContent` was removed without substitution.
+
+
+Impact
+======
+
+Frontend output may change.
+
+
+Affected installations
+======================
+
+A TYPO3 instance is affected if own TypoScript operates with :ts:`styles.insertContent`. This is pretty unlikely since the styles segment was hidden in the TypoScript Object Browser.
+
+
+Migration
+=========
+
+Either remove usage of :ts:`styles.insertContent` or add a snippet at an early point in TypoScript for backwards compatibility.
+
+::
+
+  styles.insertContent = CONTENT
+  styles.insertContent {
+    table = tt_content
+    select {
+      orderBy = sorting
+      where = colPos=0

+=========================================
+
+Description
+===========
+
+File EXT:felogin/pi1/class.tx_felogin_pi1.php was removed.
+
+
+Impact
+======
+
+ - A require in PHP of this file throws a fatal error.
+
+ - An includeLibs TypoScript setting to this file raises a warning.
+
+
+Affected installations
+======================
+
+A TYPO3 instance is affected if a 3rd party extension requires EXT:felogin/pi1/class.tx_felogin_pi1.php or if an includeLibs TypoScript setting to this file is set.
+
+
+Migration
+=========
+
+Remove the require line in PHP and includeLibs line in TypoScript, they are obsolete.

+Handling of $GLOBALS['TBE_STYLES']['loginBoxImage_rotationFolder'] and $GLOBALS['TBE_STYLES']['loginBoxImage_author'] was dropped.

+
+
+Migration
+=========
+
+Remove these options and their usage from the affected 3rd party extension or unload the extension.

+Feature: #60064 - Logging Framework Introspection Processor
+===========================================================
+
+Description
+===========
+
+The introspection processor of the logging framework was extended to log the full PHP backtrace and not only the last
+element of a backtrace.
+
+Two options were added to enable this feature:
+
+ - :code:`appendFullBackTrace`, boolean, not mandatory` Add full backtrace to the log
+
+ - :code:`shiftBackTraceLevel`, integer, default 0, not mandatory` Removes the given number of entries from the top of the backtrace stack.
+
+Impact
+======
+
+The introspection processor behaves as before as long as the feature is not explicitly configured.
