+[Last month](../2024-08), we talked about the major milestone of the `v0.22`
+release of the `multiboot2` crate, where all Undefined Behaviour (UB) and a
+bunch of safety and memory issues have been removed / fixed. After a short
+grace-period of one month, we now yanked all prior releases. As all of them
+contain UB, sensitive low-level software can break in subtle ways.
+
+We hope that all users can have a smooth migration to `v0.22` or above
+(with Rust 1.70 from June 2023 as MSRV). If there are problems, we
+are happy to temporarily unyank certain versions or create a `v0.22.x`
+with a lower MSRV. We can discuss this
+[here](https://github.com/rust-osdev/multiboot2/issues/237).
+
+Further, we released `v0.23` which contains dependency bumps and missing
+tags. Specifically:
+- ApmTag
+- BootdevTag
+- NetworkTag
+
+Please find more in the [changelog](https://github.com/rust-osdev/multiboot2/blob/main/multiboot2/CHANGELOG.md).
