+- [(`rust-osdev/volatile`) Various improvements for the new design](https://github.com/rust-osdev/volatile/pull/28)
 
-_No tasks were proposed for this section._
+  We are currently discussing a new design for the `volatile` crate based on raw pointer types in order to avoid potential undefined behavior. The linked pull requests proposes an implementation where the volatile wrapper type is `Copy` and its methods take `self` by value. We haven't reached a decision yet, so if anyone has more input on this, please join the discussion. For more context, see also [PR #22](https://github.com/rust-osdev/volatile/pull/22).
