This has been generated running the following Sniffs, all them part of the Moodle's CodeSniffer standard: - PSR12.Functions.ReturnTypeDeclaration - PSR12.Functions.NullableTypeDeclaration - moodle.Methods.MethodDeclarationSpacing - Squiz.Whitespace.ScopeKeywordSpacing All them are, exclusively, about correct spacing, so the changes are, all them, only white space changes. Only exceptions to the above are 3 changes what were setting the return type in a new line, and, when that happens, the closing parenthesis (bracket) has to go to the same line than the colon.
