 A WebSocket server and client for Zig — a fork of
 [karlseguin/websocket.zig](https://github.com/karlseguin/websocket.zig) by Karl
-Seguin, maintained for Zig **0.16**.
+Seguin, maintained for Zig **0.17** (0.16: use the v0.1.x tags).

 ## what this fork changes
 
-- Zig **0.16** `std.Io` threaded through the server: `WorkerState.init(allocator, io, config)`.
+- Zig **0.17** `std.Io` threaded through the server: `WorkerState.init(allocator, io, config)`.
 - `Server.runIo` for callers that own a `std.Io` listener and task lifecycle.
 - plain HTTP fallback dispatch on the same listener used for WebSocket upgrades.
 - bounded, independently configurable WebSocket-client and ordinary-HTTP drain
   periods for `runIo` and blocking-mode shutdown.
-- a 0.16-compatible test runner.
+- a 0.17-compatible test runner.
 
 Otherwise it tracks upstream. Full upstream documentation (server + client
 examples, options, migration links) is preserved below; the additions above are
