(@alexdowad) Style/EmptyLinesAroundClassBody,Style/EmptyLinesAroundModuleBody, andStyle/EmptyLinesAroundBlockBodyaccept an empty body with no blank line, even if configured toempty_linesstyle. This is because the empty lines only serve to provide a break between the header, body, and footer, and are redundant if there is no body. (@alexdowad)- #2554:
Style/FirstMethodArgumentLineBreakhandles implicit hash arguments without braces;Style/FirstHashElementLineBreakstill handles those with braces. (@alexdowad) Style/TrailingCommahas been split intoStyle/TrailingCommaInArgumentsandStyle/TrailingCommaInLiteral. (@alexdowad)- RuboCop returns process exit code 2 if it fails due to bad configuration, bad CLI options, or an internal error. If it runs successfully but finds one or more offenses, it still exits with code 1, as was previously the case. This is helpful when invoking RuboCop programmatically, perhaps from a script.
