 ## Zig Version Support Matrix
 
-|  Refname  | libuv Version  | Compatible Zig Version(s) |
-|-----------|----------------|---------------------------|
-| `v1.50.0` | `1.50.0`       | `0.14.0`, `0.15.0-dev`    |
-|  `main`   | `1.51.0`       | `0.14.0`, `0.15.0-dev`    |
+> [!IMPORTANT]
+> Compatible zig versions labeled `-dev` are maintained on a best-effort basis and are likely to break as the compiler and zig build system develop. Tag-based refs are immutable and will not be updated when the zig build system has a backward incompatible change.
