### RBS
* Generics type parameters can be bounded ([PR](https://github.com/ruby/rbs/pull/844)).
```rbs
# `T` must be compatible with the `_Output` interface.
# `PrettyPrint[String]` is ok, but `PrettyPrint[Integer]` is a type error.
class PrettyPrint[T < _Output]
interface _Output
def <<: (String) -> void
end
attr_reader output: T
def initialize: (T output) -> void
end
```
* Type aliases can be generic. ([PR](https://github.com/ruby/rbs/pull/823))
```rbs
# Defines a generic type `list`.
type list[T] = [ T, list[T] ]
| nil
type str_list = list[String]
type int_list = list[Integer]
```
* [rbs collection](https://github.com/ruby/rbs/blob/master/docs/collection.md) has been introduced to manage gems’ RBSs.
* Many signatures for built-in and standard libraries have been added/updated.
* It includes many bug fixes and performance improvements too.
See the [CHANGELOG.md](https://github.com/ruby/rbs/blob/master/CHANGELOG.md) for more information.
