# Revision History for Microkit

## Release 2.3.1

This release contains a security fix, various bug fixes, and new board support.

### Security

* Endpoint and Notification capabilities now only get the rights they need.
Previously the tool gave all rights, which let a let a PD do more than
intended. For example, a client PD with a PPC to a server PD can receive
on the server's Endpoint and consume all the messages meant for the server.

### Bug fixes

* When using the domain scheduler, a VM's VCPUs are now placed in the same
domain as the VMM PD. Previously VM performance was badly degraded.
* The tool now checks that VM priority in the SDF are valid.
* The second CPU cluster on the RockPro64 is now enabled in SMP
configurations.
* The tool now reports an error for duplicate MSI or I/O APIC interrupt
sources. The kernel does not detect this, so it previously went
unnoticed.

### Board support

* Raspberry Pi 5B

### Known issue

* Currently, on x86-64, VMs will not work if you create more than 1 VM per
system or use the SMP configuration of `x86_64_generic_vtx`. This is due
to a bug in seL4, which was fixed in
[PR 1732](https://github.com/seL4/seL4/pull/1732). The fix will be brought
to Microkit on the next seL4 and Microkit release.
