# Changelog 2022 12 28

### Fixes & improvements

- API: Added a `branch_logical_size_limit` attribute to the Neon API [Project](/guides/apis-sdks-reference-api-projects-get-project) response body, which shows the logical data size limit for project branches. This attribute replaces the `logical_size_limit` attribute, which was shown in the [Branch](/guides/apis-sdks-reference-api-branches-get-project-branch) response body. The [Neon Free Tier](/guides/plans-billing-plans) limits the logical data size of a branch to 3072 MiB (3 GiB).
- API: Added the ability to delete or reassign the endpoint associated with a project's root branch. Previously, these actions could not be performed on the endpoint associated with a project's root branch. You can edit or delete an endpoint by selecting **Edit** or **Delete** from the kebab menu in the table on the **Endpoints** page.
- API: Updated descriptions and examples in the [Neon API Reference](/guides/ai-agents-on-neon-reference-api).
- API: Added validation to ensure that the name specified when creating a role does not exceed 63 bytes. Role names longer than 63 bytes caused compute startup issues.
- Control Plane: Migrated older branches that were created using the Neon API v1 to their parent project. Branches created with Neon API v1 existed as separate Neon projects. After the migration, the branches exist as Neon API v2 branch and endpoint objects that belong to a parent project. Connection strings for migrated branches, which use the old `project_id` in the hostname, are no longer valid. Instead of the `project_id`, an `endpoint_id` must be specified in the hostname. For information about constructing a valid connection string, see [Connect from any application](/guides/postgres-connect-connect-from-any-app). An email with migration instructions was sent to affected users.
- UI: Added a **Pooler enabled** toggle control to the **Edit endpoint** dialog to permit enabling or disabling connection pooling for endpoint compute instances. The same control is available on the **Create endpoint** dialog. Previously, connection pooling was enabled or disabled for a project, and the control was located in **Settings > General**. Connection pooling is disabled, by default. For more information about Neon's connection pooling feature, see [Connection pooling](/guides/postgres-connect-connection-pooling).
- UI: Completed the migration of the Neon Console from Neon API v1 to [Neon API v2](/guides/ai-agents-on-neon-reference-api). The Neon API v1 is deprecated.
- UI: Added a **Region** column to the **Projects** dialog in the Neon Console to show the region where a Neon project resides.
- UI: Improved WebSockets integration with the Neon Console, and added Websocket support for endpoint updates.
- UI: Passwords are now temporarily displayed in the **Connection Details** widget on the project **Dashboard** after project creation and password reset operations. The password is displayed until you navigate away from the Neon Console or refresh the browser.
