How do you know wether your Linux server (which has no desktop update notifier or unattended security updates running) does need to be updated? Of course an
apt-get update && apt-get --dry-run upgrade
might give an indication. But what of the package upgrades do stand for security risks and whose are only simple bugfixes you do not care about?
Check using APT
One useful possibility is apticron which will tell you which packages should be upgraded and why. It presents you the package ChangeLog to decided wether you want to upgrade a package or not. Similar but less details is cron-apt which also informs you of new package updates.

h5ai is a modern file indexer for HTTP web servers with focus on your files.
