LogGraphic 1.16.4 release notes
Release date:
Target: Kali Linux Rolling / amd64 (x86_64)
Debian package version: 1.16.4-20260918075854
Added and fixed in 1.16.4
- Added a compact ADDRESS FLOW panel to the main dashboard. It shows deliveries between email addresses separately from MAIL FLOW, which shows traffic between servers.
- Thin lines connect sender and recipient nodes at their vertical centers.
- Follows the main search, event type filter and playback time. Shows up to six recent deliveries, newest first; the visible count depends on panel height.
- Supports LIVE updates and real-time traffic animation. Increasing log playback speed does not accelerate the particles.
- Shows the sender's source IP and hostname. Hover for full addresses, timestamp, delivery outcome, Postfix server and registration-country information.
- Click the panel to open the existing detailed address-flow window, which uses its own full-period view and filters.
- A newly added panel, or a reset layout, places ADDRESS FLOW in a separate row immediately below the metric cards. Previously saved ADDRESS FLOW positions and sizes are preserved.
- Choose Edit > Show and go to ADDRESS FLOW to reveal the panel and scroll to it.
- Supports visibility toggles, drag-and-drop placement, resizing and saved layouts. Preview copies are limited to six records.
Key improvements included when upgrading from the previously published 1.13.0
- 1.16.3: Fixed invalid memory deallocation during LIVE parsing after many malformed NOQUEUE log entries. Unified queue metadata and retention-order management and added regression tests.
- 1.16.2: Fixed world-map line endpoints appearing outside their countries.
- 1.16.1: Added incoming/outgoing directions and real-time animation to the world map.
- 1.16.0: Removed the demo feature. Added a log start date and time to limit display and statistics. Bounded retained LIVE data and reduced duplicate copies between windows.
Upgrade
Run these commands on a Kali machine with the repository already configured:
sudo apt update
sudo apt install --only-upgrade loggraphic
apt update refreshes package information. Run the second command to upgrade the app itself.
For a new installation, use sudo apt install loggraphic.
Quit and reopen LogGraphic after upgrading, then select Edit > Show and go to ADDRESS FLOW.
Check version 1.16.4 in the Help menu's version dialog.
To use the app in English, choose Settings > Language > English and restart the app.
Validation and limitations
- Mac and Kali builds succeeded; all four CTest tests passed on both platforms.
- Tests cover independent ADDRESS FLOW placement, bounded preview size, exclusion of future events and exclusion of records with missing addresses.
- The 1.16.3 memory fix was verified with ASan/UBSan and the original 20,001-line reproducer.
- Full GUI acceptance testing on Kali and long-running LIVE monitoring against a real server were not performed for this release.
- The compact panel only shows delivery outcomes with both sender and recipient addresses recorded.
- Country labels include registration information and country-code domain estimates; they do not guarantee an IP address's physical location.
- The GUI requires a Kali desktop session or configured display forwarding.
