+## Group hierarchy on CoValue creation
+
+When creating CoValues that contain other CoValues using plain JSON objects, Jazz not only creates
+the necessary CoValues automatically but it will also manage their group ownership.
+
+<CodeGroup>
+```ts twoslash
+import { co, z } from "jazz-tools";
+
+// ---cut---
+const Task = co.plainText();
+const Column = co.list(Task);
+const Board = co.map({
+  title: z.string(),
+  columns: co.list(Column),
+});
+
+const board = Board.create({
+  title: "My board",
+  columns: [
+    ["Task 1.1", "Task 1.2"],
+    ["Task 2.1", "Task 2.2"],
+  ],
+});
+```
+</CodeGroup>
+
+For each created column and task CoValue, Jazz also creates a new group as its owner and
+adds the referencing CoValue's owner as a member of that group. This means permissions for nested CoValues 
+are inherited from the CoValue that references them, but can also be modified independently for each CoValue
+if needed.
+
+<CodeGroup>
+```ts twoslash
+import { co, z, Group, Account } from "jazz-tools";
+
+const alice = {} as unknown as Account;
+const bob = {} as unknown as Account;
+const Task = co.plainText();
+const Column = co.list(Task);
+const Board = co.map({
+  title: z.string(),
+  columns: co.list(Column),
+});
+// ---cut---
+const writeAccess = Group.create();
+writeAccess.addMember(bob, "writer");
+
+// Give Bob write access to the board, columns and tasks
+const board = Board.create({
+  title: "My board",
+  columns: [
+    ["Task 1.1", "Task 1.2"],
+    ["Task 2.1", "Task 2.2"],
+  ],
+}, writeAccess);
+
+// Give Alice read access to one specific task
+const task = board.columns[0][0];
+const taskGroup = task._owner.castAs(Group);
+taskGroup.addMember(alice, "reader");
+```
+</CodeGroup>
+
+If you prefer to manage permissions differently, you can always create CoValues explicitly:
+
+<CodeGroup>
+```ts twoslash
+import { co, Group, z, Account } from "jazz-tools";
+
+const bob = {} as unknown as Account;
+const Task = co.plainText();
+const Column = co.list(Task);
+const Board = co.map({
+  title: z.string(),
+  columns: co.list(Column),
+});
+
+// ---cut---
+const writeAccess = Group.create();
+writeAccess.addMember(bob, "writer");
+const readAccess =  Group.create();
+readAccess.addMember(bob, "reader");
+
+// Give Bob read access to the board and write access to the columns and tasks
+const board = Board.create({
+  title: "My board",
+  columns: co.list(Column).create([
+    ["Task 1.1", "Task 1.2"],
+    ["Task 2.1", "Task 2.2"],
+  ], writeAccess),
+}, readAccess);
+```

-**Jazz is a toolkit for building backendless apps**. You get data without needing a database — plus auth, permissions, files and multiplayer without needing a backend. Jazz lets you do everything right from the frontend and you'll ship better apps, faster.
+**Jazz is a new kind of database** that's **distributed** across your frontend, containers, serverless functions and its own storage cloud.
 
-Instead of wrestling with databases, APIs, and server infrastructure, you work with **CoValues** ("collaborative values") — your new cloud-synced building blocks that feel like local state but automatically sync across all devices and users in real-time.
+It syncs structured data, files and LLM streams instantly, and looks like local reactive JSON state.

-
-Most apps rebuild the same thing: shared state that syncs between users and devices. Jazz starts from that shared state, giving you:
-
-- **No backend required** — Focus on building features, not infrastructure
-- **Real-time sync** — Changes appear everywhere immediately
-- **Multiplayer by default** — Collaboration just works
-- **Local-first** — Your app works offline and feels instant

-Think Figma, Notion, or Linear — but you don't need years to build a custom stack.

 # cojson
 
+## 0.16.6
+
+### Patch Changes
+
+- 67e0968: Fix content streaming chunking, now chunks should be splitted always respecting the MAX_RECOMMENDED_TX_SIZE
+- ce9ca54: Chunk CoPlainText content to avoid generating bg messages when the user past a megabytes of text
+- 4b99ff1: Add a multi-storage scheduler to avoid conflicting store operations when having multiple storage instances open on the same database
+- ac5d20d: Add ingress and egress metering
+- 9bf7946: Added a TTL based optional garbage collection for covalues
+
+## 0.16.5
+
+### Patch Changes
+
+- 3cd1586: Makes the key rotation not fail when child groups are unavailable or their readkey is not accessible.
+
+  Also changes the Group.removeMember method to not return a Promise, because:
+
+  - All the locally available child groups are rotated immediately
+  - All the remote child groups are rotated in background, but since they are not locally available the user won't need the new key immediately
+
+- 267f689: Groups: fix the readkey not being revealed to everyone when doing a key rotation
+
+## 0.16.4
+
+### Patch Changes
+
+- f9d538f: Fix the error raised when extending a group without having child groups loaded
+- 802b5a3: Refactor local updates sync to ensure that the changes are synced respecting the insertion order
