 ## Most FAQ:
 
-- Q: **Zap doesn't build with Zig master?**
-- A: <mark>**Zap depends on the latest stable release of Zig**, which is **ZIG
-  V0.11**</mark> at the moment. Contributers provide forks with v0.12/master
-  branches which I may integrate soon-ish.
-    - A2: Going "stable" is a deliberate decision. Zap is designed to be
-      depended on by professional, production-grade servers, not just toy
-      projects or Zig/Zap enthusiasts. Having zap not break with frequent
-      changes of zig master, is a feature. We experienced the catch-up game when
-      Zig 0.11 was in development and decided that it might be a big turn-off,
-      especially for professional projects.
-    - A3: We're going to add a `zig-master` branch soon. (Probably early 2024).
 - Q: **Does ZAP work on Windows?**
 - A: No. This is due to the underlying facil.io C library. Future versions of
   facil.io might support Windows but there is no timeline yet. Your best options
