OBS Studio 32.2.0 Released with SDR&to HDR Composer Sniffnet 1.5.1 added Latency Check Ubuntu 26.04 DEB

Sniffnet, the popular network traffic monitoring software, released new 1.5.1 version today.

The new version of this free open-source software added some minor new features, translation updates, and fixed some issues.

Without the requirement of running ping command from terminal, the new version now displays Latency row in the connection details page.

To avoid extra traffic for every captured connection, user needs to do a single click on the button to measure the latency from local computer to the destination IP. And, it will cache the result for per remote IP while the app is running.

This version also improved the IP blacklists import by adding CIDR ranges support. Previously, it only supports exact IPv4/IPv6 addresses, such as 8.8.8.8 and 2001:db8::1.

Now, CIDR ranges that represent a block of IP addresses are also support. Meaning you can import IP blacklists contain something look like 1.2.3.0/24 that represents IP from 1.2.3.0 to 1.2.3.255, and 2001:db8::/32 for all IPv6 addresses whose first 32 bits are 2001:0db8.

And, it improved the import feedback by showing status details such as no blacklist file selected, file read error, no valid IP/CIDR entries found, and successful load with parsed entry counts.
