# 0.4.0
## Breaking
- Make `Mapper::map_to` and `Mapper::identity_map` unsafe because it is possible to break memory safety by passing invalid arguments.
- Rename `FrameAllocator::alloc` to `allocate_frame` and `FrameDeallocator::dealloc` to `deallocate_frame`.
- Remove `From<os_bootinfo::FrameRange>` implementation for `PhysFrameRange`
- The `os_bootinfo` crate is no longer used by the `bootloader` crate.
- It is not possible to provide an implementation for all `os_bootinfo` versions.
## Other
- Update to 2018 edition
# 0.3.6
- Add a `SIZE` constant to the `Page` type
- Add two interrupt tests to the `testing` sub-crate
