- Fixed two local vulnerabilities: CVE-2022-21394 (Severity 6.5 out of 10) and CVE-2022-21295 (Severity 3.8). The second vulnerability appears only on the Windows platform. Details on the nature of the problems have not yet been given.
- The virtual machine manager has resolved issues with OS/2 stability in guest systems in environments with new AMD processors (problems arose due to the lack of a TLB flush operation in OS/2).

- An issue with incorrect positioning of the mouse cursor in text mode has been resolved in guests.
- Guest Control improves Unicode handling and resolves issues with copying directories between the host environment and the guest system.
