Please note that the point release does not constitute a new version of Debian 9 but only updates some of the packages included. There is no need to throw away old “stretch” media. After installation, packages can be upgraded to the current versions using an up-to-date Debian mirror.
Those who frequently install updates from security.debian.org won’t have to update many packages, and most such updates are included in the point release.
New installation images will be available soon at the regular locations.
Upgrading an existing installation to this revision can be achieved by pointing the package management system at one of Debian’s many HTTP mirrors. A comprehensive list of mirrors is available at:
