Debian Project has just announced the first update of the fixed distribution Debian 9 (code name “stretch”).
The first update mainly adds security fixes, along with some adjustments for serious problems seen from the first 9 release.
Security patches have already been published separately.
Note that the point release is not a new version of Stretch, according to distribution developers, but it only updates some of the packages included. So there is no need to throw away the old Stretch ISOs.
After installation, packages can be upgraded to current versions using one of the updated mirrors of Debian Project.
Those who frequently install updates from security.debian.org will not need to update many packages as most updates are included in the point release.
The new ISO installations will be available soon in regular repositories.
Upgrading an existing installation to this revision can be accomplished by adding the system managements packages of one of the Debian Project's many updated HTTP mirrors.
So if you want to upgrade first before receiving all the repositories of the distribution, you can add one of the updated mirrors.
