# Changelog 2023 03 16

### Fractional compute sizes

Added support for fractional Compute Units (CU), enabling configuration of compute endpoints with a quarter or half CU. Each CU allocates approximately 4 GB of RAM. <img src="../img/site-assets/neon.com/docs/changelog/fractional_computes.png" alt="Fractional compute sizes">

### Fixes & improvements

- API: Added a `suspend_timeout_seconds` property to the Endpoint API, which specifies the duration of inactivity (in seconds) after which a compute endpoint is automatically suspended.
- UI: Adjusted the labels and text on the **Edit Compute Endpoint** dialog.
- UI: Added support for Pro Plan customers to change payment details. Payment details can be changed by editing the **Payment method** on the **Billing** page in the Neon Console.
- UI: Added a **Request subscription cancellation** button to the **Billing** page in the Neon Console, which opens an **Unsubscribe** dialog. Customers can use the dialog to submit a plan cancellation request.
- UI: Revised the cancellation warning on the **Billing** page in the Neon Console.
- UI: Added a safety limit of 20 active compute endpoints. When the limit is exceeded, an endpoint is created but not activated.
- UI: When creating a branch, a complete connection string with the user name, password, and database name is now provided in the **Connection Details** dialog that is shown after branch creation.
- UI: Added a **Usage** widget to the Neon **Dashboard** for monitoring project usage. The usage widget tracks metrics such as **Active time**, **Compute time**, **Project storage**, **Branches**, and **Current data size**.
- UI: Added more domains to the console's Content Security Policy (CSP) HTTP response headers to enhance Neon Console security. CSP headers provide an additional layer of security for web pages by allowing a website to control what resources (such as scripts, stylesheets, and images) can be loaded and executed on its pages.
