     -- PHPCBF always uses this setting to reduce memory
     -- Setting $recordErrors in custom reports no longer supported
 
+  - Squiz LowercasePHPFunctionsSniff now uses the internal function list so it can ignore included global functions
+    -- This can happen if functions are defined by calling vendor/autoload.php
+    -- Thanks to Michael Butler for the patch
   - Fixed bug #945 : Incorrect indent behavior using deep-nested function and arrays
   - Fixed bug #961 : Two anonymous functions passed as function/method arguments cause indentation false positive
   - Fixed bug #1007 : Squiz Unreachable code detection is not working properly with a closure inside a case
