### What?
Fixes potential errors when passed to `sanitizeRelationships` `ref`
could potentially be a non object (for example `string`) because of
having in the database data in old structure.
```
"Cannot create property 'a' on string 'B'",
```
### Why?
Necessary particularly for the migration script, as it migrates
everything including versions that can have outdated data.
### How?
Ensures passed `ref` is an `object`.
### What?
Upgrades mongoose from 6 to latest `v8.8.1`
Fixes https://github.com/payloadcms/payload/issues/9171
### Why?
Compatibilty with Mongodb Atlas
### How?
- Updates deps
- Changed ObjectId from bson-objectid to use `new Type.ObjectId` from
mongoose for compatibility (only inside of db-mongodb)
- Internal type adjustments
https://github.com/payloadcms/payload/discussions/9088
BREAKING CHANGES:
All projects with existing data having versions enabled, or relationship or upload fields will want to create the predefined migration that converts all strings to ObjectIDs where needed. This can be created using `payload migrate:create --file @payloadcms/mongodb/relationships-v2-v3`.
For projects making use of the exposed Models from mongoose, review the
upgrade guides from [v6 to
v7](https://mongoosejs.com/docs/7.x/docs/migrating_to_7.html) and [v7 to
v8](https://mongoosejs.com/docs/migrating_to_8.html) and make
adjustments as needed.

The mongodb adapter `updateOne` method accepts an `options` argument
that allows query options to be passed to mongoose. This parameter was
added in https://github.com/payloadcms/payload/pull/8397 to support the
`upsert` operation.
This `options` parameter can also be useful when using the database
adaptor directly without going through the local api. It is true that
the Mongoose models could be used directly in such situations, but the
adapter methods include a lot of useful functionality, like for instance
the sanitization of document and relationship ids, so it is desirable to
be able to use the adapter functions while still being able to provide
mongoose query options (e.g. `{timestamps: false}`).
This PR adds the same options parameter to the other update methods of
the mongodb adapter.
### What?
Uses the `collection.dbName` property for the Mongoose model, if
defined.
### Why?
Currently, `collection.dbName` is used for the version name but not for
the actual collection name. Additionally, `autoPluralization` modifies
the `dbName` regardless. This behavior is inconsistent and contradicts
the documentation.
### How?
- Utilize `collection.dbName` instead of `collection.slug`.
- Disable `autoPluralization` for collections with a defined `dbName`.
Related: https://github.com/payloadcms/payload/discussions/9058
**BREAKING CHANGES**
If a `dbName` was previously provided, it will now be used as the
MongoDB collection name instead of the collection `slug`.
`autoPluralization` will not be applied to `dbName`.

This fixes a peer dependency error in our monorepo, as
eslint-plugin-jsx-a11y finally supports eslint v9.
Additionally, this officially adds TypeScript 5.6 support for
typescript-eslint.
Previously, when filtering the internal link relationship in lexical by
typing in the relationship field, it would throw an error, as that
relationship field has a relation to "date-fields".
Currently, Payload renders all custom components on initial compile of
the admin panel. This is problematic for two key reasons:
1. Custom components do not receive contextual data, i.e. fields do not
receive their field data, edit views do not receive their document data,
etc.
2. Components are unnecessarily rendered before they are used
This was initially required to support React Server Components within
the Payload Admin Panel for two key reasons:
1. Fields can be dynamically rendered within arrays, blocks, etc.
2. Documents can be recursively rendered within a "drawer" UI, i.e.
relationship fields
3. Payload supports server/client component composition
In order to achieve this, components need to be rendered on the server
and passed as "slots" to the client. Currently, the pattern for this is
to render custom server components in the "client config". Then when a
view or field is needed to be rendered, we first check the client config
for a "pre-rendered" component, otherwise render our client-side
fallback component.
But for the reasons listed above, this pattern doesn't exactly make
custom server components very useful within the Payload Admin Panel,
which is where this PR comes in. Now, instead of pre-rendering all
components on initial compile, we're able to render custom components
_on demand_, only as they are needed.
To achieve this, we've established [this
pattern](https://github.com/payloadcms/payload/pull/8481) of React
Server Functions in the Payload Admin Panel. With Server Functions, we
can iterate the Payload Config and return JSX through React's
`text/x-component` content-type. This means we're able to pass
contextual props to custom components, such as data for fields and
views.
## Breaking Changes
1. Add the following to your root layout file, typically located at
`(app)/(payload)/layout.tsx`:
```diff
/* THIS FILE WAS GENERATED AUTOMATICALLY BY PAYLOAD. */
/* DO NOT MODIFY IT BECAUSE IT COULD BE REWRITTEN AT ANY TIME. */
+ import type { ServerFunctionClient } from 'payload'
import config from '@payload-config'
import { RootLayout } from '@payloadcms/next/layouts'
import { handleServerFunctions } from '@payloadcms/next/utilities'
import React from 'react'
import { importMap } from './admin/importMap.js'
import './custom.scss'
type Args = {
children: React.ReactNode
}
+ const serverFunctions: ServerFunctionClient = async function (args) {
+ 'use server'
+ return handleServerFunctions({
+ ...args,
+ config,
+ importMap,
+ })
+ }
const Layout = ({ children }: Args) => (
<RootLayout
config={config}
importMap={importMap}
+ serverFunctions={serverFunctions}
>
{children}
</RootLayout>
)
export default Layout
```
2. If you were previously posting to the `/api/form-state` endpoint, it
no longer exists. Instead, you'll need to invoke the `form-state` Server
Function, which can be done through the _new_ `getFormState` utility:
```diff
- import { getFormState } from '@payloadcms/ui'
- const { state } = await getFormState({
- apiRoute: '',
- body: {
- // ...
- },
- serverURL: ''
- })
+ const { getFormState } = useServerFunctions()
+
+ const { state } = await getFormState({
+ // ...
+ })
```
## Breaking Changes
```diff
- useFieldProps()
- useCellProps()
```
More details coming soon.

### What?
Adds full support for the point field to Postgres and Vercel Postgres
adapters through the Postgis extension. Fully the same API as with
MongoDB, including support for `near`, `within` and `intersects`
operators.
Additionally, exposes to adapter args:
*
`tablesFilter`https://orm.drizzle.team/docs/drizzle-kit-push#including-tables-schemas-and-extensions.
* `extensions` list of extensions to create, for example `['vector',
'pg_search']`, `postgis` is created automatically if there's any point
field
### Why?
It's essential to support that field type, especially if the postgres
adapter should be out of beta on 3.0 stable.
### How?
* Bumps `drizzle-orm` to `0.36.1` and `drizzle-kit` to `0.28.0` as we
need this change https://github.com/drizzle-team/drizzle-orm/pull/3141
* Uses its functions to achieve querying functionality, for example the
`near` operator works through `ST_DWithin` or `intersects` through
`ST_Intersects`.
* Removes MongoDB condition from all point field tests, but keeps for
SQLite
Resolves these discussions:
https://github.com/payloadcms/payload/discussions/8996https://github.com/payloadcms/payload/discussions/8644
### What?
Moved the logic for copying the data.id to data._id to the mongoose
adapter.
### Why?
If you have any hooks that need to set the `id`, the value does not get
sent to mongodb as you would expect since it was copied before the
beforeValidate hooks.
### How?
Now data._id is assigned only in the mongodb adapter's `create`
function.
BREAKING CHANGES:
When using custom ID fields, if you have any collection hooks for
beforeValidate, beforeChange then `data._id` will no longer be assigned
as this happens now in the database adapter. Use `data.id` instead.
### What?
Fixes issue with incorrect `totalDocs` value when an aggregation is used
for `find`.
Previously, `limit: 5` for example always returned `totalDocs: 5`.
### Why?
`totalDocs` must be returned correctly.
### How?
Removes `$limit` from the pipeline, as `Model.aggregatePaginate` handles
it by itself.
### What?
Makes it possible to filter join documents using a `where` added
directly in the config.
### Why?
It makes the join field more powerful for adding contextual meaning to
the documents being returned. For example, maybe you have a
`requiresAction` field that you set and you can have a join that
automatically filters the documents to those that need attention.
### How?
In the database adapter, we merge the requested `where` to the `where`
defined on the field.
On the frontend the results are filtered using the `filterOptions`
property in the component.

### What?
Fixes `select` handling for properties inside of unnamed tabs using the
mongodb adapter.
Additionally, refactors `traverseFields` in drizzle to reuse logic from
groups / collapsible or rows if unnamed.
### Why?
`select` must work for any fields.
### How?
Fixes the `'tab'` case in `buildProjectionFromSelect` to handle when the
field is an unnamed tab.
Adds extra tests for named tabs / unnamed.
### What?
Properly specifies `$lookup.from` when the collection name is singular.
### Why?
MongoDB can pluralize the collection name and so can be different for
singular ones.
### How?
Uses the collection name from the driver directly
`adapter.collections[slug].collection.name` instead of just `slug`.
Adds `select` which is used to specify the field projection for local
and rest API calls. This is available as an optimization to reduce the
payload's of requests and make the database queries more efficient.
Includes:
- [x] generate types for the `select` property
- [x] infer the return type by `select` with 2 modes - include (`field:
true`) and exclude (`field: false`)
- [x] lots of integration tests, including deep fields / localization
etc
- [x] implement the property in db adapters
- [x] implement the property in the local api for most operations
- [x] implement the property in the rest api
- [x] docs

### What?
Fixes the issue with `in` querying when the collection has a join field.
### Why?
When using `.aggregate`, MongoDB doesn't cast a comma delimited value
for the `$in` operator to an array automatically as it's not handled by
Mongoose.
### How?
Sanitizes the incoming value to an array if it should.
Fixes https://github.com/payloadcms/payload/issues/8901
### What?
Allow specifying the defaultSort and defaultLimit to use for populating
a join field
### Why?
It is much easier to set defaults rather than be forced to always call
the join query using the query pattern ("?joins[categories][limit]=0").
### How?
See docs and type changes
This change adds support for sort with multiple fields in local API and
REST API. Related discussion #2089

This PR makes a more clear gap between `version_createdAt` /
`version_updatedAt` and `createdAt` / `updatedAt` columns / fields in
mongodb.
- `createdAt` - This should be a new value in a new version. Before this
change it was the same all the time. Should remain the same on autosave.
- The same for `updatedAt`, but it should be updated on every change
(including autosave)
- `version_createdAt` - Should remain equal to `createdAt` from the
parent collection / table
- `version_updatedAt` - On a latest version it makes sense this be the
same as `updatedAt` from the parent collection / table, as all the
`version_*` fields should be just synced with it
- Adds the upsert method to the database interface
- Adds a mongodb specific option to extend the updateOne to accept
mongoDB Query Options (to pass `upsert: true`)
- Added upsert method to all database adapters
- Uses db.upsert in the payload preferences update operation
Includes a test using payload-preferences
## Description
- Adds a new "join" field type to Payload and is supported by all database adapters
- The UI uses a table view for the new field
- `db-mongodb` changes relationships to be stored as ObjectIDs instead of strings (for now querying works using both types internally to the DB so no data migration should be necessary unless you're querying directly, see breaking changes for details
- Adds a reusable traverseFields utility to Payload to make it easier to work with nested fields, used internally and for plugin maintainers
```ts
export const Categories: CollectionConfig = {
slug: 'categories',
fields: [
{
name: 'relatedPosts',
type: 'join',
collection: 'posts',
on: 'category',
}
]
}
```
BREAKING CHANGES:
All mongodb relationship and upload values will be stored as MongoDB ObjectIDs instead of strings going forward. If you have existing data and you are querying data directly, outside of Payload's APIs, you get different results. For example, a `contains` query will no longer works given a partial ID of a relationship since the ObjectID requires the whole identifier to work.

## Description
Adds `virtual` property to the fields config. Providing `true`
completely disables the field in the DB, which is useful for [Virtual
Fields](https://payloadcms.com/blog/learn-how-virtual-fields-can-help-solve-common-cms-challenges)
Disables abillity to query by a field with `virtual: true`.
Currently, they bloat the DB with unused tables / columns, which may as
well introduce additional joins.

The `BlockField` type is not representative of the underlying "blocks"
field type, which is plural, i.e. `BlocksField`. This is a semantic
change that will better align the type with the field.
## Breaking Changes
Types related to the `blocks` field have change names. If you were using
the `BlockField` or related types in your own applications, simply
change the import name to be plural and instead of singular.
Old (singular):
```ts
import type {
BlockField,
BlockFieldClient,
BlockFieldValidation,
BlockFieldDescriptionClientComponent,
BlockFieldDescriptionServerComponent,
BlockFieldErrorClientComponent,
BlocksFieldErrorServerComponent,
BlockFieldLabelClientComponent,
BlockFieldLabelServerComponent,
} from 'payload'
```
New (plural):
```ts
import type {
BlocksField,
BlocksFieldClient,
BlocksFieldValidation,
BlocksFieldDescriptionClientComponent,
BlocksFieldDescriptionServerComponent,
BlocksFieldErrorClientComponent,
BlocksFieldErrorServerComponent,
BlocksFieldLabelClientComponent,
BlocksFieldLabelServerComponent,
} from 'payload'
```
Dedicated adapter for Vercel Postgres
- Uses the `@vercel/postgres` package under the hood.
- No `pg` dependency, speeds up invocation
- Includes refactoring all base postgres functionality into a
`BasePostgresAdapter` type, which will ease implementation of [other
adapters supported by
drizzle-orm](https://orm.drizzle.team/docs/get-started-postgresql)
## Usage
```ts
import { buildConfig } from 'payload'
import { vercelPostgresAdapter } from '@payloadcms/db-vercel-postgres'
export default buildConfig({
db: vercelPostgresAdapter({
pool: {
connectionString: process.env.DATABASE_URI,
},
}),
// ...rest of config
})
```
### Automatic Connection String Detection
Have Vercel automatically detect from environment variable (typically
`process.env.POSTGRES_URL`)
```ts
export default buildConfig({
db: postgresAdapter(),
// ...rest of config
})
```
Supports `hasMany` upload fields, similar to how `hasMany` works in
other fields, i.e.:
```ts
{
type: 'upload',
relationTo: 'media',
hasMany: true
}
```

Allow a compound index to be used for upload collections via a
`filenameCompoundIndex` field. Previously, `filename` was always treated
as unique.
Usage:
```ts
{
slug: 'upload-field',
upload: {
// Slugs to include in compound index
filenameCompoundIndex: ['filename', 'alt'],
},
}
```
This PR makes three major changes to the codebase:
1. [Component Paths](#component-paths)
Instead of importing custom components into your config directly, they
are now defined as file paths and rendered only when needed. That way
the Payload config will be significantly more lightweight, and ensures
that the Payload config is 100% server-only and Node-safe. Related
discussion: https://github.com/payloadcms/payload/discussions/6938
2. [Client Config](#client-config)
Deprecates the component map by merging its logic into the client
config. The main goal of this change is for performance and
simplification. There was no need to deeply iterate over the Payload
config twice, once for the component map, and another for the client
config. Instead, we can do everything in the client config one time.
This has also dramatically simplified the client side prop drilling
through the UI library. Now, all components can share the same client
config which matches the exact shape of their Payload config (with the
exception of non-serializable props and mapped custom components).
3. [Custom client component are no longer
server-rendered](#custom-client-components-are-no-longer-server-rendered)
Previously, custom components would be server-rendered, no matter if
they are server or client components. Now, only server components are
rendered on the server. Client components are automatically detected,
and simply get passed through as `MappedComponent` to be rendered fully
client-side.
## Component Paths
Instead of importing custom components into your config directly, they
are now defined as file paths and rendered only when needed. That way
the Payload config will be significantly more lightweight, and ensures
that the Payload config is 100% server-only and Node-safe. Related
discussion: https://github.com/payloadcms/payload/discussions/6938
In order to reference any custom components in the Payload config, you
now have to specify a string path to the component instead of importing
it.
Old:
```ts
import { MyComponent2} from './MyComponent2.js'
admin: {
components: {
Label: MyComponent2
},
},
```
New:
```ts
admin: {
components: {
Label: '/collections/Posts/MyComponent2.js#MyComponent2', // <= has to be a relative path based on a baseDir configured in the Payload config - NOT relative based on the importing file
},
},
```
### Local API within Next.js routes
Previously, if you used the Payload Local API within Next.js pages, all
the client-side modules are being added to the bundle for that specific
page, even if you only need server-side functionality.
This `/test` route, which uses the Payload local API, was previously 460
kb. It is now down to 91 kb and does not bundle the Payload client-side
admin panel anymore.
All tests done
[here](https://github.com/payloadcms/payload-3.0-demo/tree/feat/path-test)
with beta.67/PR, db-mongodb and default richtext-lexical:
**dev /admin before:**
**dev /admin after:**
---
**dev /test before:**
**dev /test after:**
---
**build before:**
**build after::**
### Usage of the Payload Local API / config outside of Next.js
This will make it a lot easier to use the Payload config / local API in
other, server-side contexts. Previously, you might encounter errors due
to client files (like .scss files) not being allowed to be imported.
## Client Config
Deprecates the component map by merging its logic into the client
config. The main goal of this change is for performance and
simplification. There was no need to deeply iterate over the Payload
config twice, once for the component map, and another for the client
config. Instead, we can do everything in the client config one time.
This has also dramatically simplified the client side prop drilling
through the UI library. Now, all components can share the same client
config which matches the exact shape of their Payload config (with the
exception of non-serializable props and mapped custom components).
This is breaking change. The `useComponentMap` hook no longer exists,
and most component props have changed (for the better):
```ts
const { componentMap } = useComponentMap() // old
const { config } = useConfig() // new
```
The `useConfig` hook has also changed in shape, `config` is now a
property _within_ the context obj:
```ts
const config = useConfig() // old
const { config } = useConfig() // new
```
## Custom Client Components are no longer server rendered
Previously, custom components would be server-rendered, no matter if
they are server or client components. Now, only server components are
rendered on the server. Client components are automatically detected,
and simply get passed through as `MappedComponent` to be rendered fully
client-side.
The benefit of this change:
Custom client components can now receive props. Previously, the only way
for them to receive dynamic props from a parent client component was to
use hooks, e.g. `useFieldProps()`. Now, we do have the option of passing
in props to the custom components directly, if they are client
components. This will be simpler than having to look for the correct
hook.
This makes rendering them on the client a little bit more complex, as
you now have to check if that component is a server component (=>
already has been rendered) or a client component (=> not rendered yet,
has to be rendered here). However, this added complexity has been
alleviated through the easy-to-use `<RenderMappedComponent />` helper.
This helper now also handles rendering arrays of custom components (e.g.
beforeList, beforeLogin ...), which actually makes rendering custom
components easier in some cases.
## Misc improvements
This PR includes misc, breaking changes. For example, we previously
allowed unions between components and config object for the same
property. E.g. for the custom view property, you were allowed to pass in
a custom component or an object with other properties, alongside a
custom component.
Those union types are now gone. You can now either pass an object, or a
component. The previous `{ View: MyViewComponent}` is now `{ View: {
Component: MyViewComponent} }` or `{ View: { Default: { Component:
MyViewComponent} } }`.
This dramatically simplifies the way we read & process those properties,
especially in buildComponentMap. We can now simply check for the
existence of one specific property, which always has to be a component,
instead of running cursed runtime checks on a shared union property
which could contain a component, but could also contain functions or
objects.

## Description
Prior to this change, the `defaultValue` for fields have only been used
in the application layer of Payload. With this change, you get the added
benefit of having the database columns get the default also. This is
especially helpful when adding new columns to postgres with existing
data to avoid needing to write complex migrations. In MongoDB this
change applies the default to the Mongoose model which is useful when
calling payload.db.create() directly.
This only works for statically defined values.

**BREAKING:**
- The `deepMerge` exported from payload now handles more complex data and
is slower. The old, simple deepMerge is now exported as `deepMergeSimple`
- `combineMerge` is no longer exported. You can use
`deepMergeWithCombinedArrays` instead
- The behavior of the exported `deepCopyObject` and `isPlainObject` may
be different and more reliable, as the underlying algorithm has changed
