# CS:Govern 1.65.1

Release Date: 28-Apr-2026

This is a Salesforce API version upgrade release. As always, existing CS:Govern configuration files are backwards compatible.

## Patch Levels

| Date        | Patch Level      |
| ----------- | ---------------- |
| 28-Apr-2026 | Original Release |

## Important: Salesforce Username/Password Login Deprecated

Salesforce API version 65 deprecates the SOAP username/password login endpoint. Customers should migrate to an external client application configured with OAuth. CS:Govern execution using a login type that does not support API 65 will automatically fall back to API 64, and an exception will be logged when running tasks.

This exception can not be eliminated until OAuth authentication is used. 

**Salesforce API Version Fallback for Username/Password Logins**

The "Fallback API Detected" error does **not** stop jobs from running - it is informational, and indicates that CopyStorm is not able to use the most recent Salesforce API features. The error will be resolved when updating to JWT (or other OAuth) authentication.

Please reference [Salesforce OAuth Login Types.](https://learn.capstorm.com/frequently-asked-questions/usage/where-does-copystorm-store-passwords/salesforce-oauth-login-types)

## Salesforce API Update

This release updates CS:Govern to use Salesforce API version 65.
