The recently imposed "must be logged in" restriction is a response to increased bot traffic on the site. This affects search, commits, and vuxml pages.
Search engines are not blocked. Try using "site:www.freshports.org" and your search terms.
After the ports freeze to fix some stuff, the freeze is over. I have some work to do before FreshPorts can start processing commits again before it can start processing again. I've created an issue for that.

Description:
diffsnap is a lightweight, on-demand snapshot scheduler for OpenZFS where snapshots are generated only when a configured change threshold is met. It supports per-dataset scheduling intervals, retention counts, recursive snapshots, and minimum byte thresholds. The utility is completely daemonless, uses native zfs commands, handles locking to prevent overlapping runs, and safely prunes old snapshots matching only its own prefix context.
