Overview Download Prereleases

Download prerelease versions

Prerelease versions are builds from active development, published after significant bug fixes or when new features are added. They give you early access to what's coming and help us catch issues before a wider release. Please report anything you find!

Installing a prerelease version opts you into the prerelease update channel. You can switch back by installing a stable release or by changing the channel in the override configuration file for software_update.toml.

Release Notes

May 19, 2026

Little Snitch for Linux 1.1-pre1 (1010001)

This version introduces a major new feature: automatic software update notifications. When a new version of Little Snitch becomes available, you will now be notified directly in the UI.

Because this feature involves more moving parts than it might appear to, we are rolling it out in a prerelease first. Installing this prerelease version will automatically switch you to the prerelease update channel, meaning you will receive notifications for prereleases only. Once this feature ships in a stable release, installing that stable version will return you to the stable channel.

We recognise that automatic update checks raise privacy concerns for some users. You can disable this feature by creating an empty file at:

/var/lib/littlesnitch/override/config/software_update.toml

If you do so, you can stay up to date by monitoring our download page or subscribing to GitHub releases instead.

The update behaviour can be fully customised by editing software_update.toml in the config override directory. This allows redistributors to point to alternative update channels or disable automatic update checks entirely.
