🆕 You can now sponsor LuLu/Objective-See Foundation:

LuLu v4.0.1

🔎 Improved Logging
Per request, added a dedicated debug log msg that shows: Process → Endpoint → Rule → Decision.

To filter on, from Terminal, run:

log stream --level debug --predicate 'subsystem == "com.objective-see.lulu" && composedMessage BEGINSWITH "[LULU]"'

🚮 Rules UI
Reverted logic that would hide HTTP/S ports for endpoint rules, as it was a bit confusing to determine whether rule was then for all ports, or just the HTTP/S ones.

👥 New Feature: Profiles (#574)

A profile defines a set of rules and settings. Once activated, the profile's settings apply LuLu-wide and can be modified via LuLu's Settings panes. Any changes to settings or rules (as well as any new rules) will apply only to that profile.

⏸️ New Feature: Disable Rules (#353)
Either individual rules, or all rules for an entire process can now be disabled

✅ macOS 26 Compatibility Improvements

🪟 Rule's Window Improvements
'Hamburger' menu added contain rule options, such as disable, delete, view paths, etc.
Hitting delete on your keyboard, on a selected rule, will also delete the rule. Also, default ports (80/443) are hidden in rules to make the UI cleaner.

🚮 Rule Cleanup
Expired and temporary rules now automatically cleaned up / removed

🇮🇹 Additional Localization(s)
Italian

✍🏼 Improved Passive Rule Creation (#782)
Passive mode rule creation now prioritizes domain names over IP addresses. Now, when passive mode creates rules automatically, they will show meaningful names like github.com instead of 140.82.112.3:443.

🔗 Changes to VirusTotal Integration
Due to an API key being deprecated, VirusTotal button now open's VirusTotal's report in default browser
