# Revision History for Microkit

## Release 2.4.0

This release contains security and bug fixes.
This release is breaking.

### Breaking changes

* seL4 has been updated from 16.0.0 to 17.0.0, which includes breaking
changes for virtual machines. Please see the
[kernel's changelog](https://github.com/seL4/seL4/releases/tag/17.0.0)
for upgrade notes.

### Security

* Reply capabilities no longer have grant reply permission. Previously a
server could send capabilities over a reply.
* PDs no longer get their parent's fault endpoint capability. Previously,
in 2.3.1, a PD could send its parent fake faults with arbitrary messages.
In 2.3.0 and earlier, a PD could receive, and so consume, fault IPCs
meant for the parent.

### Bug fixes

* VMs on x86-64 now work with more than 1 VM per system and in the SMP
configuration of `x86_64_generic_vtx`. This was a known issue in 2.3.1
and earlier, caused by a bug in seL4 that was fixed in
[PR 1732](https://github.com/seL4/seL4/pull/1732).

## Release 2.3.1

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