# Unreleased
# 0.4.0-alpha.1 - 2019-08-11
* **Pin projection has become a safe operation.**
* `#[unsafe_project]` has been replaced with `#[pin_project]`.
* The `Unpin` argument has been removed - an `Unpin` impl is now generated by default.
* Drop impls must be specified with `#[pinned_drop]` instead of via a normal `Drop` impl.
* `Unpin` impls must be specified with an impl of `UnsafeUnpin`, instead of implementing the normal `Unpin` trait.
* Made `#[project]` attribute disabled by default.
