The Debian project is pleased to announce the fourth update of its
stable distribution Debian 9 (codename "stretch"). 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 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
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:
