The second release candidate of Deepin V23 is now available for downloading and testing. The release offers new features and optimizations, such as the "Backup Update" toggle button, updated system fonts, and improved video decoding compatibility. The package also contains a new nvidia-graphics-drivers package and a new installer trial mode. The display style of the encrypted network lock icon has been changed to match the interface when the machine is not locked.

Basic package upgrades include corrections for known security flaws, increased performance and multithreading capabilities, and improved internationalization support. Compiler improvements have been performed, and Python interaction with Version 3.12 has been enhanced for faster execution and memory economy. Package management capabilities and performance have been improved, as well as the efficiency and reliability of the package management tool.

deepin V23 RC2 Is Officially Released 

The official release of deepin V23 RC2 is here! We invite everyone to try it out and provide feedback. We also thank every member of the deepin community for their ideas and suggestions. Together, let's strive to create an open-source operating system that is beautiful, easy to use, and reliable!

 【New Features and Optimizations】

• Added "Backup Update" toggle feature: Access the Control Center - Update Settings - Other Settings, and turn off the toggle to perform system updates without backing up the system (use with caution).
• Newly integrated system fonts include WenQuanYi Micro Hei, WenQuanYi Zheng Hei, and WenQuanYi dot-matrix Song.
• Updated the closed-source nvidia-graphics-drivers package.
• Optimized to enhance video decoding compatibility, supporting decoding of multiple video streams and playback of videos in various resolutions.
• Optimized to reduce the number of snapshots to prevent the /boot/ partition from being filled up by kernel snapshots due to backups.
• Optimized the installer trial mode to support selection of system language and keyboard layout before entering the system (currently, "Time Zone" must be selected after entering the system).
• Optimized the display style of the encrypted network lock icon on the lock screen interface, which was too small; it has been modified to be consistent with the interface when the system is not locked.
