Fort Firewall 3.20.4 has been released as a maintenance update, introducing features such as a style-sheet option, text-based network editing, and support for ARM64 architecture, while also updating its SQLite engine. This release is part of a rapid redesign cycle that has reworked various functionalities, including groups and speed limits, since version 3.20.0. However, users must disable Windows Core Isolation (Memory Integrity/HVCI) for the software to function, a requirement that has been misunderstood in some reviews. Despite being a solo project, the developer maintains a strong pace of updates and transparency, ensuring the code remains auditable and accessible to the community
Fort Firewall 3.20.4 Released: New Release Brings Style-Sheet Option and ARM64 Support
Fort Firewall 3.20.4 as a small maintenance release, adding a style-sheet option, text-based network editing, an updated SQLite engine, and an ARM64-aware Inno Setup installer. It lands within an aggressive 3.20 redesign cycle that reworked Groups, speed limits, schedules, and the Filter Simulator. The catch hasn't changed: Fort still requires Windows Core Isolation (Memory Integrity/HVCI) to be switched off, a real security trade-off. Worth noting that a popular third-party review got that requirement backwards, so check the official docs before trusting secondary sources.
