+
+* [fu5ha](https://github.com/fu5ha) added the `NoUninit`, `AnyBitPattern`, and
+  `CheckedBitPattern` traits. This allows for a more fine-grained level of

+  This is a "preview" of the direction that the crate will probably go in the
+  eventual 2.0 version. We're still waiting on [Project Safe
+  Transmute](https://github.com/rust-lang/project-safe-transmute) for an actual
+  2.0 version of the crate, but until then please enjoy this preview.
+* Also Fusha added better support for `union` types in the derive macros. I
+  still don't know how any of the proc-macro stuff works at all, so please
