Nightly builds are pre-release versions of Little Snitch that include the latest bug fixes and feature enhancements.
This version uses an improved but incompatible file format to archive the current rule set and preferences. The old archive file is preserved. If you downgrade to a previous version, all changes made since this upgrade will be reverted. Backup files are still created in a backward-compatible format.
Improved handling of processes without code signature in Silent Mode. When there was a matching allow-rule for “Any Process” requiring a valid code signature, Little Snitch considered the unsigned process as case of likely tampering and inserted a high priority deny-rule. We now just skip the matching rule and act according to Silent Mode (allow or deny).
If the matching rule requires a particular code signature (from a particular developer), we still consider it as case of likely tampering and add a high priority deny rule. The process has been seen with a valid code signature before, so the code signature must have been removed.
