 In this month, we released a new version 0.8.3 which includes [a bug fix](https://github.com/rust-osdev/xhci/pull/132) reported and committed by [@Yuna-Tomi](https://github.com/Yuna-Tomi). The bug was that `EventRingDequeuePointerRegister::event_ring_dequeue_pointer()` did not return the correct address. Thanks for the contribution!.

+
+The `multiboot2` crate provides abstraction types for the multiboot information structure (MBI) of multiboot2 
+bootloaders. The latest release of the `multiboot2`-crate is now `v.0.13.2` (was `v0.13.1`). It contains minor 
+improvements, such as that `TagType` implements `Ord`.
