## Changes from previous versions
### API changes
This version comes with the following changes to the APIs:
**New API to replay a service task after a Cloud Connector failure**
In the case where a service task has failed due to a failure in a Cloud Connector, it's possible to replay the task and send a new integration request to the connector. You need to provide the execution id and the definition id of the service task (id in the XML file):
```
POST /rb/admin/v1/executions/{executionId}/replay/service-task
{
"flowNodeId": "flowNodeId"
}
```
**Adds the group parameter to the user search API**
* `GET /v1/identity/users?group=hr`
**Retrieves all the roles of a user from Keycloak**
* `GET /v1/identity/roles`
The API works in a similar way to a proxy and makes a call to the keycloak API to get the roles and return them.
Example response:
```
{
"globalAccess": {
"roles": [
"ACTIVITI_USER",
"ACTIVITI_DEVOPS"
]
},
"applicationAccess":
[
{
"name": "simpleapp",
"roles": [
"ACTIVITI_USER"
]
},
{
"name": "myapp",
"roles": [
"ACTIVITI_USER"
]
}
]
}
```
**Variables marked as displayable can be returned in the** `/tasks` **and** `/process-instances` **query service endpoints**
In order to be returned in the response body of tasks and process instances, the variables should be marked as displayable in modeling app and be referenced in the`variableDefinitions` query parameter:
Example request for tasks:\
`GET /query/v1/tasks?variableDefinitions=fa22874c-ea1a-4243-9edf-33738ec5efd3&variableDefinitions=29a55c30-fb90-4224-ad42-e9fd275d5ed6`

### Improvements
Previously, if a connector failed a new integration request was not sent. Now you can send a new integration request so the process instance can continue its execution.
### Software Updates
* Updated Spring Boot version to 2.7.0.
* Updated Spring Cloud version to 2021.0.2.
### Bug fixes
* When you ran an application with `spring.jpa.open-in-view=false`, the query in `org.activiti.cloud.services.query.rest.ProcessInstanceService#findAllWithVariables` did not enable the filter `variableDefinitionIds` and subsequently returned all variables. Now the filter limits the returned variables.
* Identity endpoints in the modeling service were only available to users with role `Modeler`. Now all the endpoints are available to all authenticated users.
