# NEWS for Ruby 4.1.0
|
|
|
|
This document is a list of user-visible feature changes
|
|
since the **4.0.0** release, except for bug fixes.
|
|
|
|
Note that each entry is kept to a minimum, see links for details.
|
|
|
|
## Language changes
|
|
|
|
## Core classes updates
|
|
|
|
Note: We're only listing outstanding class updates.
|
|
|
|
* Method
|
|
|
|
* `Method#source_location`, `Proc#source_location`, and
|
|
`UnboundMethod#source_location` now return extended location
|
|
information with 5 elements: `[path, start_line, start_column,
|
|
end_line, end_column]`. The previous 2-element format `[path,
|
|
line]` can still be obtained by calling `.take(2)` on the result.
