LogGraphic 1.16.4 release notes

Release date: September 18, 2026

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.

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.

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.

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.
