The Debian Project has announced the release of Debian 10.3 and Debian 9.12. Debian’s point releases roll up all the latest updates into the disc image which allows people to install fewer updates after installing Debian on their systems. The updates don’t bring new features but include security patches and a few adjustments for serious problems.
If you’re already using Debian 9 or 10, there’s no need to reinstall them to get the latest changes bundled with the latest point releases, instead just check for available updates in the update manager or command line. If you’ve applied all of the available patches, you’re effectively running the latest images.
Some of the changes in this update include six removed packages and fixes to the Debian Installer to make it more stable. Several packages received security updates including Firefox ESR, Thunderbird, the Linux kernel, Chromium, Ruby, Wordpress, and OpenJDK. Other packages have received miscellaneous bugfixes like ClamAV, Python, systemd, and sudo.
If you’re still using Debian 9 or are thinking about installing it, keep in mind that official security updates from the Debian project end sometime this year. It will be shifted over to the long term support branch where it will be patched by volunteers and companies instead of the Debian security team. LTS support for Debian 9 will last until June 2022.
