- server: inherited roles for PG queries and subscription
- server: fix issue when a remote relationship's joining field had a custom GraphQL name defined (fix #6626)
- cli: add support for rest endpoints
- cli: support mssql sources
- cli: use relative paths in metadata !include directives
- cli: rename `--database` flag in `migrate` and `seed` command to `--database-name`
## v2.0.0-alpha.3
### Bug fixes and improvements
- server/mssql: fix malformed JSON answer on empty tables
- server/mssql: fix runtime errors when selecting geography/geometry columns
- server/mssql: supports connection pooling to sql server
- server/mssql: fix text values erroneously being parsed as varchar
- server: improve errors messages for inconsistent sources
- console: add relationship tab for mssql tables (#677)
- build: fix the packaging of static console assets (fix #6610)
## v2.0.0-alpha.2
### MSSQL support
It's now possible to add a MSSQL server as a source. For now, only read-only queries and subscriptions are supported.
See the documentation at `graphql/core/databases/ms-sql-server` for more information.
## v2.0.0-alpha.1
Bunch of bug fixes and refactor for generalized backends: https://github.com/hasura/graphql-engine/compare/v1.4.0-alpha.2...v2.0.0-alpha.1
## v1.4.0-alpha.2
### Inconsistent Metadata
Add `allow_inconsistent_metadata` option to `replace_metadata` API.
This will replace metadata even if there are inconsistency errors,
returning a 200 response code and `is_consistent` and `inconsistent_objects`
keys in the response body.
### Bug fixes and improvements
(Add entries here in the order of: server, console, cli, docs, others)
- server: fix issue of not exposing mutation functions to the admin role when function permissions are inferred (fix #6503)
- server: add "resource_version" field to metadata for concurrency control - disable lookup during migrations
- server: fix issue with queries on character column types (close #6217)
- server: optimize resolving source. Resolving a source would create connection pools every time. Optimize that to re-create connection pools only when necessary. (#609)
- server: fix issues with remote schema introspection and queries over TLS.
- console: add support for MS SQL Server
- server: Prohibit Invalid slashes, duplicate variables, subscriptions for REST endpoints
- server: Prohibit non-singular query definitions for REST endpoints
- server: better handling for one-to-one relationships via both `manual_configuration` and `foreign_key_constraint_on` (#2576)
## v1.4.0-alpha.1
### REST Endpoints
The RESTified GraphQL Endpoints API allows for the use of a REST interface to saved GraphQL queries and mutations.
Users specify the query or mutation they wish to make available, as well a URL template. Segments of the URL template can potentially capture data to be used as GraphQL variables.
See the documentation at `graphql/core/api-reference/restified` for more information.
### Heterogeneous execution
Previous releases have allowed queries to request data from either Postgres or remote schemas, but not both. This release removes that restriction, so multiple data sources may be mixed within a single query. For example, GraphQL Engine can execute a query like
```
query {
articles {
title
}
weather {
temperature
}
}
```
where the articles are fetched from the database, and the weather is fetched from a remote server.
### Support tracking VOLATILE SQL functions as mutations. (closing #1514)
Previously we could only track `STABLE` or `IMMUTABLE` functions, and only as
queries. Now the version 2 of `track_table` also supports tracking functions as
mutations:
```
{
"type": "track_function",
"version": 2,
"args": {
"function": {
"schema": "public",
"name": "some_volatile_function"
},
"configuration": {
"exposed_as": "mutation"
}
}
}
```
### Remote schema permissions
Now, permissions can be configured for remote schemas as well, which works similar
to the permissions system of the postgres tables. Fields/arguments can be removed from the
schema and arguments can also be preset to limit the role from having unrestricted
access over it.
*NOTE*: To enable remote schema permissions, the graphql-engine needs to be started
either with the server flag ``--enable-remote-schema-permissions`` or the environment
variable ``HASURA_GRAPHQL_ENABLE_REMOTE_SCHEMA_PERMISSIONS`` set to ``true``.
### Function Permissions
Before volatile functions were supported, the permissions for functions were automatically inferred
from the select permission of the target table. Now, since volatile functions are supported we can't
do this anymore, so function permissions are introduced which will explicitly grant permission to
a function for a given role. A pre-requisite to adding a function permission is that the role should
have select permissions to the target table of the function.
### `ltree` comparison operators
Comparison operators on columns with ``ltree``, ``lquery`` or ``ltxtquery`` types are now supported, for searching through data stored in a hierarchical tree-like structure.
See the documentation at `graphql/core/queries/query-filters` more details on the currently supported ``ltree`` operators.
**Example query:** Select ancestors of an `ltree` argument
```
query {
tree (
where: {path: {_ancestor: "Tree.Collections.Pictures.Astronomy.Astronauts"}}
) {
path
}
}
```
**Example response:**
```
{
"data": {
"tree": [
{
"path": "Tree"
},
{
"path": "Tree.Collections"
},
{
"path": "Tree.Collections.Pictures"
},
{
"path": "Tree.Collections.Pictures.Astronomy"
},
{
"path": "Tree.Collections.Pictures.Astronomy.Astronauts"
}
]
}
}
```
### Breaking changes
- This release contains the [PDV refactor (#4111)](https://github.com/hasura/graphql-engine/pull/4111), a significant rewrite of the internals of the server, which did include some breaking changes:
- The semantics of explicit `null` values in `where` filters have changed according to the discussion in [issue 704](https://github.com/hasura/graphql-engine/issues/704#issuecomment-635571407): an explicit `null` value in a comparison input object will be treated as an error rather than resulting in the expression being evaluated to `True`. For instance: `delete_users(where: {id: {_eq: $userId}}) { name }` will yield an error if `$userId` is `null` instead of deleting all users.
- The validation of required headers has been fixed (closing #14 and #3659):
- if a query selects table `bar` through table `foo` via a relationship, the required permissions headers will be the union of the required headers of table `foo` and table `bar` (we used to only check the headers of the root table);
- if an insert does not have an `on_conflict` clause, it will not require the update permissions headers.
- This release contains the remote schema permissions feature, which introduces a breaking change:
Earlier, remote schemas were considered to be a public entity and all the roles had unrestricted
access to the remote schema. If remote schema permissions are enabled in the graphql-engine, a given
remote schema will only be accessible to a role ,if the role has permissions configured for the said remote schema
and be accessible according to the permissions that were configured for the role.
### Bug fixes and improvements
(Add entries here in the order of: server, console, cli, docs, others)
- server: add `request` field to webhook POST body containing the GraphQL query/mutation, its name, and any variables passed (close #2666)
- server: fix a regression where variables in fragments weren't accepted (fix #6303)
- server: output stack traces when encountering conflicting GraphQL types in the schema
- server: add `--websocket-compression` command-line flag for enabling websocket compression (fix #3292)

## v1.3.3
### Server - Support for mapping session variables to default JWT claims
Some auth providers do not let users add custom claims in JWT. In such cases, the server can take a JWT configuration option called `claims_map` to specify a mapping of Hasura session variables to values in existing claims via JSONPath or literal values.
Example:-
Consider the following JWT claim:
```
{
"sub": "1234567890",
"name": "John Doe",
"admin": true,
"iat": 1516239022,
"user": {
"id": "ujdh739kd",
"appRoles": ["user", "editor"]
}
}
```
The corresponding JWT config can be:
```
{
"type":"RS512",
"key": "<The public Key>",
"claims_map": {
"x-hasura-allowed-roles": {"path":"$.user.appRoles"},
"x-hasura-default-role": {"path":"$.user.appRoles[0]","default":"user"},
"x-hasura-user-id": {"path":"$.user.id"}
}
}
```
### Metadata Types SDK
The types and documentation comments for Metadata V2 have been converted into JSON/YAML Schema, and used to autogenerate type definitions for popular languages.
This enables users to build type-safe tooling in the language of their choice around Metadata interactions and automations.
Additionally, the JSON/YAML Schemas can be used to provide IntelliSense and autocomplete + documentation when interacting with Metadata YAML/JSON files.
For a more comprehensive overview, please see [the readme located here](./contrib/metadata-types/README.md)
**Sample Code**
```ts
import { TableEntry } from "../generated/HasuraMetadataV2";
const newTable: TableEntry = {
table: { schema: "public", name: "user" },
select_permissions: [
{
role: "user",
permission: {
limit: 100,
allow_aggregations: false,
columns: ["id", "name", "etc"],
computed_fields: ["my_computed_field"],
filter: {
id: { _eq: "X-Hasura-User-ID" },
},
},
},
],
};
```

### Breaking changes
#### PDV
This release contains the [PDV refactor (#4111)](https://github.com/hasura/graphql-engine/pull/4111), a significant rewrite of the internals of the server, which did include some breaking changes:
- The semantics of explicit `null` values in `where` filters have changed according to the discussion in [issue 704](https://github.com/hasura/graphql-engine/issues/704#issuecomment-635571407): an explicit `null` value in a comparison input object will be treated as an error rather than resulting in the expression being evaluated to `True`.

- if an insert does not have an `on_conflict` clause, it will not require the update permissions headers.
#### Remote Relationship
In this release, a breaking change has been introduced:
In a remote relationship query, the remote schema will be queried when all of the joining arguments
are **not** `null` values. When there are `null` value(s), the remote schema won't be queried and the
response of the remote relationship field will be `null`. Earlier, the remote schema
was queried with the `null` value arguments and the response depended upon how the remote schema handled the `null`
arguments.
### Bug fixes and improvements
(Add entries here in the order of: server, console, cli, docs, others)
- server: allow remote relationships joining `type` column with `[type]` input argument as spec allows this coercion (fixes #5133)
- server: add action-like URL templating for event triggers and remote schemas (fixes #2483)
- server: change `created_at` column type from `timestamp` to `timestamptz` for scheduled triggers tables (fix #5722)
- server: allow configuring timeouts for actions (fixes #4966)
- server: fix bug which arised when renaming a table which had a manual relationship defined (close #4158)
- server: limit the length of event trigger names (close #5786)
**NOTE:** If you have event triggers with names greater than 42 chars, then you should update their names to avoid running into Postgres identifier limit bug (#5786)
- server: enable HASURA_GRAPHQL_PG_CONN_LIFETIME by default to reclaim memory
- server: fix issue with tracking custom functions that return `SETOF` materialized view (close #5294) (#5945)
- server: allow remote relationships with union, interface and enum type fields as well (fixes #5875) (#6080)
- server: Fix fine-grained incremental cache invalidation (fix #6027)
This issue could cause enum table values to sometimes not be properly reloaded without restarting `graphql-engine`. Now a `reload_metadata` API call (or clicking “Reload enum values” in the console) should consistently force a reload of all enum table values.
- server: fix event trigger cleanup on deletion via replace_metadata (fix #5461) (#6137)
**WARNING**: This can cause significant load on PG on startup if you have lots of event triggers. Delay in starting up is expected.
- console: add notifications (#5070)
- cli: fix bug in metadata apply which made the server aquire some redundant and unnecessary locks (close #6115)
- cli: fix cli-migrations-v2 image failing to run as a non root user (close #4651, close #5333)
- cli: fix issue with cli binary on latest Mac (Big Sur) (fix #5462)

## `v1.3.0-beta.1`
### Relay
The Hasura GraphQL Engine serves [Relay](https://relay.dev/en/) schema for Postgres tables which has a primary key defined.
The Relay schema can be accessed through `/v1beta1/relay` endpoint.
[Add docs links][add console screenshot for relay toggle]
### Remote Joins
Remote Joins extend the concept of joining data across tables, to being able to join data across tables and remote schemas.
It works similar to table relationships. Head to the `Relationship` tab in your table page and define a remote relationship:
1. give a name for the relationship
2. select the remote schema
3. give the join configuration from table columns to remote schema fields.
[Add docs links][add console screenshot]
### Scheduled Triggers
A scheduled trigger can be used to execute custom business logic based on time. There are two types of timing events: cron based or timestamp based.
A cron trigger will be useful when something needs to be done periodically. For example, you can create a cron trigger to generate an end-of-day sales report every weekday at 9pm.
You can also schedule one-off events based on a timestamp. For example, a new scheduled event can be created for 2 weeks from when a user signs up to send them an email about their experience.

(close #1914)
### Allow access to session variables by computed fields (fix #3846)
Sometimes it is useful for computed fields to have access to the Hasura session variables directly. For example, suppose you want to fetch some articles but also get related user info, say `likedByMe`. Now, you can define a function like:
```
CREATE OR REPLACE FUNCTION article_liked(article_row article, hasura_session json)
RETURNS boolean AS $$
SELECT EXISTS (
SELECT 1
FROM liked_article A
WHERE A.user_id = hasura_session ->> 'x-hasura-user-id' AND A.article_id = article_row.id
);
$$ LANGUAGE sql STABLE;
```
and make a query like:
```
query {
articles {
title
content
likedByMe
}
}
```
Support for this is now added through the `add_computed_field` API.
Read more about the session argument for computed fields in the [docs](https://hasura.io/docs/latest/graphql/core/api-reference/schema-metadata-api/computed-field.html).
### Manage seed migrations as SQL files
A new `seeds` command is introduced in CLI, this will allow managing seed migrations as SQL files
#### Creating seed
```
# create a new seed file and use editor to add SQL content
hasura seed create new_table_seed
# create a new seed by exporting data from tables already present in the database
hasura seed create table1_seed --from-table table1
# create from data in multiple tables:
hasura seed create tables_seed --from-table table1 --from-table table2
```
#### Applying seed
```
# apply all seeds on the database:
hasura seed apply
# apply only a particular seed
hasura seed apply --file 1234_add_some_seed_data.sql
```
### Bug fixes and improvements
(Add entries here in the order of: server, console, cli, docs, others)

## `v1.2.0`
Include the changelog from **v1.2.0-beta.1**, **v1.2.0-beta.2**, **v1.2.0-beta.3**, **v1.2.0-beta.4**, **v1.2.0-beta.5**
Additional changelog:
### CLI: Support servers with self-signed certificates (close #4564) (#4582)
A new flag `--certificate-authority` is added so that the CA certificate can be
provided to trust the Hasura Endpoint with a self-signed SSL certificate.
Another flag `--insecure-skip-tls-verification` is added to skip verifying the certificate
in case you don't have access to the CA certificate. As the name suggests,
using this flag is insecure since verification is not carried out.

## `v1.2.0-beta.5`
### server: backend only insert permissions
Introduces optional `backend_only` (default: `false`) configuration in insert permissions
(see [api reference](https://deploy-preview-4224--hasura-docs.netlify.com/graphql/manual/api-reference/schema-metadata-api/permission.html#insertpermission)).
If this is set to `true`, the insert mutation is accessible to the role only if the request
is accompanied by `x-hasura-use-backend-only-permissions` session variable whose value is set to `true` along with the `x-hasura-admin-secret` header.
Otherwise, the behavior of the permission remains unchanged.
This feature is highly useful in disabling `insert_table` mutation for a role from frontend clients while still being able to access it from a Action webhook handler (with the same role).
(rfc #4120) (#4224)
### server: debugging mode for non-admin roles
For any errors the server sends extra information in `extensions` field under `internal` key. Till now this was only
available for `admin` role requests. To enable this for other roles, start the server with `--dev-mode` flag or set `HASURA_GRAPHQL_DEV_MODE` env variable to `true`:
```bash
$ graphql-engine --database-url <database-url> serve --dev-mode
```
In case you want to disable `internal` field for `admin` role requests, set `--admin-internal-errors` option to `false` or or set `HASURA_GRAPHQL_ADMIN_INTERNAL_ERRORS` env variable to `false`
```bash
$ graphql-engine --database-url <database-url> serve --admin-internal-errors false
```
This feature come in handy during development when you may want to see detailed errors irrespective of roles.
**Improved internal errors for Actions**:
(This is a **breaking change** with previous 1.2.0-beta releases)
The `internal` field for action errors is improved with more debug information. It now includes `request`,
`response` and `error` fields instead of just `webhook_response` field.
Before:
```json
{
"errors": [
{
"extensions": {
"internal": {
"webhook_response": {
"age": 25,
"name": "Alice",
"id": "some-id"
}
},
"path": "$",
"code": "unexpected"
},
"message": "unexpected fields in webhook response: age"
}
]
}
```
After:
```json
{
"errors": [
{
"extensions": {
"internal": {
"error": "unexpected response",
"response": {
"status": 200,
"body": {
"age": 25,
"name": "Alice",
"id": "some-id"
},
"headers": [
{
"value": "application/json",
"name": "Content-Type"
},
{
"value": "abcd",
"name": "Set-Cookie"
}
]
},
"request": {
"body": {
"session_variables": {
"x-hasura-role": "admin"
},
"input": {
"arg": {
"age": 25,
"name": "Alice",
"id": "some-id"
}
},
"action": {
"name": "mirror"
}
},
"url": "http://127.0.0.1:5593/mirror-action",
"headers": []
}
},
"path": "$",
"code": "unexpected"
},
"message": "unexpected fields in webhook response: age"
}
]
}
```
### cli: add support for .env file
ENV vars can now be read from .env file present at the project root directory. A global flag, `--envfile`, is added so you can explicitly provide the .env filename, which defaults to `.env` filename if no flag is provided.
**Example**:
```
hasura console --envfile production.env
```
The above command will read ENV vars from `production.env` file present at the project root directory.
(close #4129) (#4454)
### console: allow setting post-update check in update permissions
Along with the check for filtering rows that can be updated, you can now set a post-update permission check that needs to be satisfied by the updated rows after the update is made.
<add-screenshot>
(close #4142) (#4313)
### console: support for Postgres [materialized views](https://www.postgresql.org/docs/current/rules-materializedviews.html)
Postgres materialized views are views that are persisted in a table-like form. They are now supported in the Hasura Console, in the same way as views. They will appear on the 'Schema' page, under the 'Data' tab, in the 'Untracked tables or views' section.
(close #91) (#4270)
### docs: map Postgres operators to corresponding Hasura operators
Map Postgres operators to corresponding Hasura operators at various places in docs and link to PG documentation for reference.
For example, see [here](https://hasura.io/docs/latest/graphql/core/api-reference/schema-metadata-api/syntax-defs.html#operator).

## `v1.2.0-beta.3`
### console: manage Postgres check constraints
Postgres Check constraints allows you to specify that the value in a certain column must satisfy a Boolean (truth-value) expression. They can be used to put in simple input validations for mutations and with this release, these constraints can now be added while creating a table or later from Modify tab on the console.
**Example**:
When a product is created, ensure that the price is greater than zero. The SQL would look like this:
```sql
CREATE TABLE products (
product_id UUID DEFAULT gen_random_uuid(),
name TEXT,
price NUMERIC CONSTRAINT positive_price CHECK (price > 0)
);
```
To create this table with Hasura Console, on the 'Add a new table' screen, after adding all the columns, scroll down to 'Check constraints' section and 'Add a new check constraint' with the following properties:
- Constraint name: `positive_price`
- Check expression: `price > 0`
Read more about check constraints on [Postgres Docs](https://www.postgresql.org/docs/12/ddl-constraints.html#DDL-CONSTRAINTS-CHECK-CONSTRAINTS).
(close #1700) (#3881)
### CLI: V2 migrations architecture
A new CLI migrations image is introduced to account for the new migrations workflow. If you're have a project with `version: 2` in `config.yaml`, you should use the new image: `hasura/graphql-engine:v1.2.0-cli-migrations-v2`. Mount the migrations at `/hasura-migrations` and metadata at `/hasura-metadata`.
See [upgrade docs](https://hasura.io/docs/latest/graphql/core/migrations/upgrade-v2.html).

## `v1.2.0-beta.1`
### Hasura Actions
Actions are a way to extend Hasura’s auto-generated mutations with entirely custom ones which can handle various use cases such as data validation, data enrichment from external sources and any other complex business logic.
A new mutation can be created either by defining its GraphQL SDL or by deriving it from an existing Hasura-generated mutation. The resolver is exposed to Hasura as a webhook which can be called synchronously or asynchronously. This release also includes an ever evolving codegen workflow to make managing the custom resolvers easier.
Read more about actions in the [docs](https://docs.hasura.io/1.0/graphql/manual/actions/index.html).
(#3042) (#3252) (#3859)
### Downgrade command
A new command is added to the server executable for downgrading to earlier releases. Previously, if you ran a newer Hasura version and wanted to go back to an old version on the same database, you had to stop Hasura, run some SQL statements and start Hasura again. With the new `downgrade` command, these SQL statements can be run automatically.
**Example**: Downgrade from `v1.2.0` to `v1.0.0`:
```bash
# stop hasura v1.2.0
# run the following command:
docker run hasura/graphql-engine:v1.2.0 graphql-engine --database-url <db-url> downgrade --to-v1.0.0
# start hasura v1.0.0
```
Read more about this command in the [docs](https://hasura.io/docs/latest/graphql/core/deployment/downgrading.html#downgrading-hasura-graphql-engine).
(close #1156) (#3760)
### Expiration of connections authenticated by WebHooks
When using webhooks to authenticate incoming requests to the GraphQL engine server, it is now possible to specify an expiration time; the connection to the server will be automatically closed if it's still running when the expiration delay is expired.
Read more about it in the [docs](https://hasura.io/docs/latest/graphql/core/auth/authentication/webhook.html).
