# NEWS for Ruby 3.2.0
This document is a list of user-visible feature changes
since the **3.1.0** release, except for bug fixes.
Note that each entry is kept to a minimum, see links for details.
## Language changes
* Anonymous rest and keyword rest arguments can now be passed as
arguments, instead of just used in method parameters.
[[Feature #18351]]
```ruby
def foo(*)
bar(*)
end
def baz(**)
quux(**)
end
```
* Constant assignment evaluation order for constants set on explicit
objects has been made consistent with single attribute assignment
evaluation order. With this code:
```ruby
foo::BAR = baz
```
`foo` is now called before `baz`. Similarly, for multiple assignment
to constants, left-to-right evaluation order is used. With this
code:
```ruby
foo1::BAR1, foo2::BAR2 = baz1, baz2
```
The following evaluation order is now used:
1. `foo1`
2. `foo2`
3. `baz1`
4. `baz2`
[[Bug #15928]]
