The Debian project is pleased to announce the fifth update of its stable distribution Debian 12 (codename bookworm). This point release mainly adds corrections for security issues, along with a few adjustments for serious problems. Security advisories have already been published separately and are referenced where available.

Please note that the point release does not constitute a new version of Debian 12 but only updates some of the packages included. There is no need to throw away old bookworm media. After installation, packages can be upgraded to the current versions using an up-to-date Debian mirror.

After 1 year, 9 months, and 28 days of development, the Debian project is proud to present its new stable version 12 (code name "bookworm").

"bookworm" will be supported for the next 5 years thanks to the combined work of the Debian Security team and the Debian Long Term Support team.

kexec是Linux内核的一种机制，它允许从当前运行的内核启动新内核。kexec会跳过由系统固件执行的引导加载程序阶段和硬件初始化阶段，直接将新内核加载到主内存并立即开始执行。这避免了与完全重新启动相关的漫长时间，并且可以通过最小化停机时间来帮助系统满足高可用性要求。
