#### New Features

- You can now rename local symbols in R files
(#13749). Renaming symbols
across files is still unsupported, but will be implemented soon.

- The "Go to Definition" and "Find References" gain support for local
symbols in R files (#8631).
You can now use these functionalities to jump to where a variable is
defined (e.g. via `<-` or a function parameter), or see all references
to a variable in a function.

#### Bug Fixes

- N/A
