+Improve CommonJS/ESM compatibility
+
+Since this release, all server utilities will be CommonJS by default unless they have referenced ESM modules in the code. For instance, `next-docs-zeta/middleware` is now a CommonJS file. However, some modules, such as `next-docs-zeta/server` requires ESM-only package, hence, they remain a ESM file.
+
+Notice that the extension of client-side files is now `.js` instead of `.mjs`, but they're still ESM.
+
+**Why?**
+
+After migrating to `.mjs` Next.js config file, some imports stopped to work. The built-in Next.js bundler seems can't resolve these `next` imports in external packages, causing errors when modules have imported Next.js itself (e.g. `next/image`) in the code.
+
+By changing client-side files extension to `.mjs` and using CommonJS for server-side files, this error is solved.

+Create `PageTreeBuilder` API
+
+The old `buildPageTree` function provided by 'next-docs-zeta/contentlayer' is now removed. Please use new API directly, or use the built-in `createContentlayer` utility instead.

+- import { buildPageTree } from 'next-docs-zeta/contentlayer'
++ import { createPageTreeBuilder } from 'next-docs-zeta/server'
