Improvements
- [Daylight saving time (DST)] Updated: DST changes for Paraguay. For more information, see the Daylight Saving Time & Time Zone Blog.
- [GB18030-2022] This update adds support for this amendment.
- [Temporary files] This update enables system processes to store temporary files in a secure directory "C:\\Windows\\SystemTemp" via either calling GetTempPath2 API or using .NET's GetTempPath API, thereby reducing the risk of unauthorized access.
- [Open Secure Shell (OpenSSH) (known issue)] Fixed: The service fails to start, which stops SSH connections. There is no detailed logging, and you must run the sshd.exe process manually.
