From the release note:

The Debian project pleased to announce the second update of its stable distribution Debian 10 (codename “buster”). 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 10 but only updates some of the packages included. There is no need to throw away old “buster” 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.
