+<span class="maintainers">Maintained by [@IsaacWoods](https://github.com/IsaacWoods)</span>
+
+The `acpi` repository contains crates for parsing the ACPI tables – data structures that the firmware of modern computers use to relay information about the hardware to the OS. We merged the following changes this month:

+
+The `ovmf-prebuilt` project provides pre-built [edk2](https://github.com/tianocore/edk2) releases to make it easier to set up OVMF. We merged the following improvement this month:
