**BREAKING CHANGE:**
This bumps the **minimum required Next.js** version from 15.0.0 to
15.2.3. This update is necessary due to a critical security
vulnerability found in earlier Next.js versions, which requires an
exception to our standard semantic versioning process.
Additionally, this bumps all templates to the latest Next.js and Payload
versions.
The Payload Admin Bar is now maintained in core and released under the
`@payloadcms` scope thanks to #3684. All templates and examples that
rely on this package now install from here and have been migrated
accordingly.
The `payload-admin-bar` now supports React 19 as a result of
https://github.com/payloadcms/payload-admin-bar/pull/13. This will
suppress the React 19 warnings on install within the website templates
and various examples that rely on this package.
There were a number of things wrong or could have been improved with the
[Draft Preview
Example](https://github.com/payloadcms/payload/tree/main/examples/draft-preview),
namely:
- The package.json was missing `"type": "modue"` which would throw ESM
related import errors on startup
- The preview secret was missing entirely, with pointless logic was
written to throw an error if it missing in the search params as opposed
to not matching the environment secret
- The `/next/exit-preview` route was duplicated twice
- The preview endpoint was unnecessarily querying the database for a
matching document as opposed to letting the underlying page itself 404
as needed, and it was also throwing an inaccurate error message
Some less critical changes were:
- The page query was missing the `depth` and `limit` parameters which is
best practice to optimize performance
- The logic to format search params in the preview URL was unnecessarily
complex
- Utilities like `generatePreviewPath` and `getGlobals` were
unnecessarily obfuscating simple functions
- The `/preview` and `/exit-preview` routes were unecessarily nested
within a `/next` page segment
- Payload types weren't aliased
In an effort to keep the Examples Directory as easy to navigate as
possible, and to keep the Payload Monorepo only as verbose as it needs
to be, we need to remove all alternatives from the Examples Directory.
This includes setups that interact with Payload from a standalone
server, keeping only the Payload recommended "combined" Next.js +
Payload setups.
