## = 1.11.0 (11.05.2020) =
Starting with PCL 1.11, PCL uses `std::shared_ptr` and `std::weak_ptr` instead of the
boost smart pointers. The change leverages type aliases included with the 1.10.0
release. PCL 1.11 also introduces `pcl::index_t` which should be used for the size
of point types instead of `int`, `std::size_t`, etc. EOL for deprecated features
is also explicitly mentioned in the deprecation compile time warnings
