Debian doesn’t follow a fixed release schedule, and that makes it somewhat hard to know exactly when a new release will be available. Debian 10, codename Buster, was released on July 6, 2019.
At any given time, there is one stable release of Debian, which has the support of the Debian security team. The new stable point release 10.9 mainly adds corrections for security issues, along with a few adjustments for serious problems.
What’s new in Debian 10.9
- Brings SBAT support to the FWUPD (daemon which allows session software to update device firmware) packages.
- Remove avahi-daemon-check-dns mechanism, which is no longer needed.
- Updated intel-microcode.
- Cloud-init, the initialization system for infrastructure cloud instances, now avoid logging generated passwords to world-readable log files.
In addition to the above, a complete list of changes can be fond in the official announcement.
How to update to to the latest stable version
Please note that the point release does not constitute a new version of Debian 10 but only updates some of the packages included.

apt update && apt upgradeIn addition, the unattended-upgrades package can be configured to perform unattended upgrades to automatically install updated packages and/or security updates. This simple tutorial will show you how to configure your Debian system to receive automatic security updates.
