Update CHANGELOG.md
Include entries about updating dependencies and fixing the ARM issue
contain the string `firecracker` to prevent from running non-firecracker
binaries.
- Rust toolchain upgraded from 1.52.1 to 1.64.0.
+- Switched to specifying our dependencies using caret requirements instead
+ of comparison requirements.
+- Updated all dependencies to their respective newest versions.
### Fixed
- Fixed the bad handling of kernel cmdline parameters when init arguments
where provided in the `boot_args` field of the JSON body of the
PUT `/boot-source` request.
+- Fixed a bug on ARM64 hosts where the upper 64bits of the V0-V31 FL/SIMD
+ registers were not saved correctly when taking a snapshot, potentially
+ leading to data loss. This change invalidates all ARM64 snapshots taken
+ with versions of Firecracker <= 1.1.3.
