Debian 10 "Buster" is available
With Debian 10 there are some software updates like the Linux Kernel 4.19, OpenJDK 11, Bash 5.0, PHP 7.3 and other packages. Furthermore, UEFI has been further improved and support for Secure Boot has been added, which now works without further configuration. This protects the boot process from manipulation by third parties. Also active is AppArmor, which offers a complex set of rules for restricting individual programs and thus increasing security.
Further information can be found in the official release announcement.
