 ## next
 
-- breaking: drop nextjs < 12.0.0 and react < 17.0.2 in [#1983](https://github.com/i18next/next-i18next/pull/1983) 
+Although it is a major, existing code should not be impacted. Only the install. 
+Read also the [UPGRADING](https://github.com/i18next/next-i18next/blob/master/UPGRADING.md) document
+to know more.
+
+- **breaking**: react-i18next and i18next are now peer-dependencies and must be installed
+  in the consuming app, see [#1966](https://github.com/i18next/next-i18next/pull/1966)
+  
+  ```bash
+  npm install react-i18next i18next --save  # NPM
+  yarn add react-i18next i18next            # Yarn
+  pnpm add react-i18next i18next --save     # PNPM
+  ```
+  
+  If you encounter any issue, please read the [Troubleshoot](https://github.com/i18next/next-i18next/blob/master/TROUBLESHOOT.md) doc.
+
+- **new:**: Upgrade to [i18next v22](https://github.com/i18next/i18next/releases) and react-i18next v12, see [#1966](https://github.com/i18next/next-i18next/pull/1966)
+- **breaking**: drop nextjs < 12.0.0 and react < 17.0.2 in [#1983](https://github.com/i18next/next-i18next/pull/1983) 
 - breaking: drop node 12.x support, requires 14.x. Recommended minimum to `^14.13.1`, 
   see [#1974](https://github.com/i18next/next-i18next/pull/1974)
 - fix: Fix types for appWithTranslation [#1987](https://github.com/i18next/next-i18next/pull/1987)

+## Version 13.x
+
+Both `i18next` and `react-i18next` have been moved to [peerDependencies](https://github.com/npm/rfcs/blob/main/implemented/0030-no-install-optional-peer-deps.md)
+and must be installed part of `next-i18next`. When upgrading don't forget to add them to your dependencies:
+
+```bash
+npm install react-i18next i18next --save  # NPM
+yarn add react-i18next i18next            # Yarn
+pnpm add react-i18next i18next --save     # PNPM
+```
+
+This move was done in the hope to avoid issues regarding duplicates. See the
+[TROUBLESHOOT](https://github.com/i18next/next-i18next/blob/master/TROUBLESHOOT.md#multiple-instances)
+for more info. In the future it will also allow to support multiple ranges.
