If they are mutated a deprecation warning is emitted. + These warnings can be enabled with `-W:deprecated` or by setting `Warning[:deprecated] = true`. + To disable this change, you can run Ruby with the `--disable-frozen-string-literal` + command line argument. [[Feature #20205]] + +* `it` is added to reference a block parameter. [[Feature #18980]] + +* Keyword splatting `nil` when calling methods is now supported. + `**nil` is treated similarly to `**{}`, passing no keywords, + and not calling any conversion methods.

[[Misc #18984]] + + + +## Compatibility issues + +Note: Excluding feature bug fixes. + +* Error messages and backtrace displays have been changed. + * Use a single quote instead of a backtick as a opening quote. [[Feature #16495]] + * Display a class name before a method name (only when the class has a permanent name). [[Feature #19117]] + * `Kernel#caller`, `Thread::Backtrace::Location`'s methods, etc. are also changed accordingly. + ``` + Old: + test.rb:1:in `foo': undefined method `time' for an instance of Integer + from test.rb:2:in `
