### Portal
- Bug (#2424): Fixed an issue where a supervisor had the rights to cancel a specific process request even when the supervisor process participant `Cancel requests` permission was disabled.
- Bug (#2605): Fixed an issue where a cancelled action would store the delegatee as the aborted user instead of the actual user (delegator) in delegation mode.

### Notifications
- Enhancement (#2433): Request data numeric values are now always formatted in text using a language culture in email notifications.

- Bug (#2608): Fixed an issue where a delegatee could cancel another request of their delegator where the specific request was not intentionally delegated to them in delegation mode.
- Bug (#2610): Fixed an issue where a delegatee could not access a request of their delegator in delegation mode.
- Bug (#2624): Fixed an issue where a standard user was able to create a new request in test mode.

### Upgrade scripts
- Change (#2598): All `alter table column` queries now use `SQL_Latin1_General_CP1_CI_AS` collation for SQL Server in our database upgrade scripts.
### Notes
- All of the Node.js modules (`GraphQL v2.0.1`, `Webhooks v4.0.1`, `Auth v1.0.0`, and `SCIM v1.0.0`) now require Node.js **version `10.15.3 LTS`**.
### Reminders
- **Microsoft Windows Server 2008 is no longer supported as of WorkflowGen version 7.11.0.** We recommend migrating to Windows Server 2012 or later.
- **Microsoft SQL Server 2008 is no longer supported as of WorkflowGen version 7.10.0.** While SQL Server 2008 is still compatible with WorkflowGen, support for any performance issues or bugs resulting from using SQL Server 2008 will no longer be provided.

We have just upgraded to 7.15.2 but we now get the following error when trying to export a process:
Cannot resolve the collation conflict between “Latin1\_General\_CI\_AS” and “SQL\_Latin1\_General\_CP1\_CI\_AS” in the UNION operation.

Hello David,
You need to set your database collation as `SQL_Latin1_General_CP1_CI_AS`, you can follow the following procedure:
> [@I receive the following SQL error when accessing WorkflowGen: A SQL error has occurred .Net SqlClient Data Provider: Invalid column name ‘RES’](https://discuss.workflowgen.com/t/i-receive-the-following-sql-error-when-accessing-workflowgen-a-sql-error-has-occurred-net-sqlclient-data-provider-invalid-column-name-res/497):
>
> Solution If you receive an SQL error indicating .NET SqlClient Data Provider: Invalid column name RES, it’s likely because your SQL Server database collation is set to Latin1\_General\_BIN, which is not compatible for use with WorkflowGen. We suggest changing your WorkflowGen database collation to the default SQL\_Latin1\_General\_CP1\_CI\_AS, since the database installation script uses this collation. To do this: Back up your WorkflowGen database. Stop all WorkflowGen services and the IIS web …

We just followed this procedure to change the collation but we still get the same error when trying to export a process.

You need to identify columns which provide the error and change the collation for these columns.
You can execute the following request to identify columns:
```sql
DECLARE @DatabaseCollation VARCHAR(100) = 'SQL_Latin1_General_CP1_CI_AS'
SELECT
t.Name 'Table Name',
c.name 'Col Name',
c.collation_name
FROM
sys.columns c
INNER JOIN
sys.tables t ON c.object_id = t.object_id
INNER JOIN
sys.types ty ON c.system_type_id = ty.system_type_id
WHERE
t.is_ms_shipped = 0
AND
c.collation_name <> @DatabaseCollation
```
