 ===== Backward Incompatible Changes ===== ===== Backward Incompatible Changes =====
-None, only interactive sessions are affected, and only when this functionality is enabled and a callback is installed.+ 
 +Only interactive sessions (''php -a'') are affected, by a difference in the output sent to stdout. The dumping of expression results can be disabled entirely with the ini setting ''cli.enable_interactive_shell_result_function = Off'', or temporarily by calling ''readline_interactive_shell_result_function(null)'' 
 + 
 +In interactive sessions, this will start calling [''__debugInfo()''|https://www.php.net/manual/en/language.oop5.magic.php#object.debuginfo] when calling ''var_dump()'' on objects, which may throw or have other side effects after the expression is evaluated.
