Changelog

Installers — unified cross-platform release

Shared install library (lib/native-install.sh) — upgrade-safe installs (no manual chmod)
Windows installer — GUI wizard (install-gui.ps1) + CLI (install.ps1) for WSL2 / Git Bash
Homebrew tap — brew tap vowlang/tap && brew trust vowlang/tap && brew install vow
All platforms — darwin-arm64, darwin-amd64, linux-amd64, linux-arm64 tarballs on install.vowlang.dev

JSON — JavaScript-style objects and arrays

Dynamic JSON in Vow now matches JavaScript ergonomics:

Feature	Example
Object literals	`{ title: "hi", count: 42 }`
Array literals	`var xs: JsonValue = [{ id: 1 }, { id: 2 }]`
Dot / bracket read	`doc.title`, `doc["title"]`, `arr[0]`
Dot / bracket write	`obj.title = "x"`, `obj["n"] = 42` (primitives auto-wrap)
Helpers	`json.get_string(doc, "title", "untitled")`

Import json from the stdlib. Full guide: JSON tutorial. Demo app: hello-app.

vow compiler — JsonValue globals, watch mode

Global JsonValue initializers — var items: JsonValue = [...] now works at runtime (array/object literals are initialized before main)
vow run --watch — delegates to vds for live reload during development
vow run binary isolation — each run uses a unique temp binary so recompiles do not stomp a running server

vow-serve 0.1.1 — vds live reload fixes

vds loads grants.toml automatically (same as vow run)
Restarts wait for the listen port to free before binding
Kills the previous process cleanly on file change

vow-web-server 0.3.4 — accept loop fix (definitive)

Fixed accept error code 2 — retrying log spam after the first page load. The single-threaded HTTP runtime now always sends Connection: close (no keep-alive reuse on one pending socket), and transient accept/bind failures retry inside C instead of bubbling to the Vow listen loop.

vow-web-server 0.3.3 — accept loop fix

Fixed a bug where idle HTTP keep-alive connections caused accept error code 2 — retrying log spam after the first page load. The runtime now retries transient accept failures internally; hello-app and other servers stay quiet while waiting for the next request.

vow-web-server 0.3.0 — Express-like API

vow-web-server@0.3.0 ships an Express-aligned registration style while keeping the v0.2 immutable builder for existing projects.

New API

Express	vow-web-server v0.3
`express()`	`server()`
`express.Router()`	`router()`
`app.use(mw)`	`use_middleware(app, mw)`
`app.use('/api', router)`	`use_middleware(app, "/api", router)`
`express.json()` / `logger()` / `urlencoded()` / `cors()`	`json()` / `logger()` / `urlencoded()` / `cors(origin)`
Custom middleware	`middleware(fn)` + `next(req)` / `halt(resp)`
`app.get/post/…`	`get(app, path, h)` — reassign handle each step
`app.listen(port)`	`serve(app, rt, port)`

Other changes

vow create my-api --web — scaffolds a packaged API with vow-web-server@0.3.0, /health + /hello, and grants.toml
Route and middleware registration returns an updated handle — use var app = vws.server(); app = vws.get(app, …) like Express reassignment patterns
Legacy app() / use_log / mount API unchanged — no breaking changes for v0.2 projects
