 ## [Unreleased]
 
+## [0.4.0] - 2026-11-03
+
+### Added
+- A top-level `write` option turns writes on for every exposed table at once: `write: true`, or `{ create, update, delete, bulk }`. A resource's own `write` replaces it, and views stay read-only unless their resource allows writes.
+- Every write example in the docs states its status, and the security page describes sensitive columns and how to serve one.

 `write: true` allows create, update and delete of every visible column. A list allows only the columns named. Generated and identity columns are never writable, and neither is a key on update.
 
+## Writes on every table
+
+For an API that writes everywhere, set `write` once, beside `expose`:
+
+```ts
+createREST({
+    db,
+    expose: { schemas: ['app'] },
+    write: true,
+    resources: {
+        audit_log: { write: false },
+        users: { write: { update: ['name'] } },
+    },
+});
+```
+
+It applies to every exposed table; views stay read-only until their resource allows writes, since many views cannot be written. A resource that sets its own `write` uses it instead: `write: false` keeps one table read-only, a column list narrows another. `write: { create: true, update: true, delete: true, bulk: true }` adds updates and deletes by filter everywhere.
+
+What is never writable stays so: hidden and sensitive columns, generated columns, and keys on update; a bulk request still needs a filter. Who may write is decided by your `authorize` hook, which receives every write with its action: see [Security](./security.md#hooks).
