# Changelog 2023 07 13

### Fixes & improvements

- Control Plane: The polling interval for a branch deletion operation was decreased from approximately 20 seconds to 1 second. A branch deletion operation typically takes a few seconds but appeared to take longer due to the polling delay.
- UI: Fixed the code example copy button in the **Connection Details** widget, which failed to remain stationary while scrolling.

### Database and role management via SQL

Neon now supports database and role management via SQL. You can now manage databases and roles from the [Neon SQL Editor](/guides/postgres-get-started-query-with-neon-sql-editor) or an SQL client, such as [psql](/guides/postgres-connect-query-with-psql-editor). Previously, databases and roles could only be managed in the Neon Console. <img src="../img/site-assets/neon.com/docs/changelog/create_database_sql.jpg" alt="Create database via SQL">

With this change, you can grant and revoke privileges for Postgres roles as you would in a stand-alone Postgres installation.

Additionally, roles created in the Neon Console, CLI, and API are now automatically granted membership in a `neon_superuser` role. This role defines the privileges required to perform tasks in Neon such as creating databases, roles, and extensions. To learn more, see [The neon\_superuser role](/guides/manage-operate-manage-roles#the-neon_superuser-role).

### Improved experience for Prisma Migrate users

Users of Prisma Migrate no longer need to manually create a shadow database in Neon.

When using the `prisma migrate dev` command, Prisma Migrate automatically creates and deletes a "shadow" database. This database enables Prisma Migrate to generate new migrations and detect schema drift, ensuring that no manual changes have been made to the development database.

Previously, running `prisma migrate dev` without manually creating and configuring a shadow database in Neon would return the following error:

```text
Error: A migration failed when applied to the shadow database Database error: Error querying the database: db error: ERROR: permission denied to create database
```

The reason for this error was that it was not possible in Neon to create and delete databases via SQL. To work around this issue, you had to manually create a shadow database in Neon and specify the connection string of that database in your `schema.prisma` file using the `shadowDatabaseUrl` variable. For example:

```text
datasource db {
provider  = "postgresql"
url       = env("DATABASE_URL")
directUrl = env("DIRECT_DATABASE_URL")
shadowDatabaseUrl = env("SHADOW_DATABASE_URL")
}
```

With support for managing databases via SQL, this workaround is no longer required. You can now remove the `shadowDatabaseUrl` variable from your `schema.prisma` file.
