Simplewall 3.9 Pre-Release Drops: Rule Limit Bump, Loopback Fixes, and Stability Updates
Simplewall 3.9 landed on GitHub as a pre-release build on July 21, 2026, delivering a suite of feature updates to the decade-old WFP-based firewall that now sits at 8,600 stars. The release bumps the rule expression limit to 1,024 symbols, sharpens loopback filtering to cut false blocks on local services, and adds environment variable support for portable profile paths. Henry++ also shipped memory optimizations that resolve crashes on Windows 11 24H2, refined the dark theme, and enabled network address resolution by default.

Simplewall 3.9 pre-release was released on GitHub on July 21, 2026, featuring significant updates including an increased rule expression limit to 1,024 symbols and improved loopback filtering to reduce false blocks on local services. The update also enhances portability by allowing profile paths to be saved with environment variables and enables network address resolution by default for dynamic IP users. Additionally, memory optimizations were introduced to address crashes on Windows 11 24H2, and improvements were made to the dark theme consistency across the UI. Despite lower engagement for this pre-release compared to regular maintenance builds, it reassures the community about the project's ongoing health amidst the development of a Rust reimplementation called amwall
