Full Release Notes

### Added

* [#4287](https://github.com/firecracker-microvm/firecracker/issues/4287): Document a caveat to the jailer docs when using the `--parent-cgroup` option, which results in it being ignored by the jailer. Refer to the [jailer documentation](./docs/jailer.md#caveats) for a workaround.

### Changed

* [#4191](https://github.com/firecracker-microvm/firecracker/pull/4191): Refactored error propagation to avoid logging and printing an error on exits with a zero exit code. Now, on successful exit "Firecracker exited successfully" is logged.

### Fixed

* [#4277](https://github.com/firecracker-microvm/firecracker/pull/4277): Fixed a bug that ignored the `--show-log-origin` option, preventing it from printing the source code file of the log messages.
* [#4179](https://github.com/firecracker-microvm/firecracker/pull/4179): Fixed a bug reporting a non-zero exit code on successful shutdown when starting Firecracker with `--no-api`.
* [#4271](https://github.com/firecracker-microvm/firecracker/pull/4271): Fixed a bug where Firecracker would log "RunWithApiError error: MicroVMStopped without an error: GenericError" when exiting after encountering an emulation error. It now correctly prints "RunWithApiError error: MicroVMStopped *with* an error: GenericError".
* [#4270](https://github.com/firecracker-microvm/firecracker/pull/4270): Fixed a bug introduced in #4047 that limited the `--level` option of logger to Pascal-cased values (e.g. accepting "Info", but not "info"). It now ignores case again.
* [#4295](https://github.com/firecracker-microvm/firecracker/pull/4295): Fixed a bug in the asynchronous virtio-block engine that rendered the device non-functional after a PATCH request was issued to Firecracker for updating the path to the host-side backing file of the device.
