Fort Firewall has released version 3.20.3 to address a traffic-counting regression from the previous version 3.20.0, which caused traffic statistics to display blank due to registration failures of new inspection filters. The update also includes a portable-mode prompt for removing the service upon quitting, fulfilling a user request from March 2025. The changelog features several interface and usability improvements, but the primary focus remains on restoring traffic counting functionality. This rapid patching reflects Fort's fast-paced development, transitioning from infrequent releases to four updates within a single week

Fort Firewall 3.20.3 Ships Quick Fix for Traffic-Counting Regression

Fort Firewall 3.20.3 is primarily to repair a traffic-counting regression introduced in the v3.20.0 rewrite just five days earlier. The bug caused new inspection filters to fail registration on some systems, which left the statistics panel and bandwidth graph completely blank. The update also adds a portable-mode prompt that asks whether to remove the service on quit, completing a trace-free cleanup workflow requested in March 2025. Open-source developer Nodir Temirkhodjaev distributed the fix as signed installers in 64-bit, 32-bit, and ARM64 builds.
