# CopyStorm/Medic 10.65.1

Release Date: 28-Apr-2026

This is a minor feature and bug fix release. As always, existing CopyStorm/Medic configuration files are backwards compatible.

#### Patch Levels

### 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. Medic jobs using a login type that does not support API 65 will automatically fall back to API 64, and an exception will be logged at the start of each job as a reminder to migrate.

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 your jobs from running - it is informational, and indicates that CopyStorm/Medic 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](/frequently-asked-questions/usage/where-does-copystorm-store-passwords/salesforce-oauth-login-types.md).

### New Features

#### Headless Support for Delete Records Tool

The Delete Records tool now supports headless execution, enabling automated and scripted delete workflows without a user interface.

#### Custom Relationship Support for Delete Records Tool

The Delete Records tool now supports XML-configured custom relationships, allowing delete operations to traverse non-standard object relationships.

#### Database Logging for Delete Records Tool

The Delete Records tool now writes job activity to the database log, improving audibility and troubleshooting for delete operations.

### Bug Fixes & Optimizations

#### Refresh Columns Memory Management Improvement

Reduced memory consumption during Refresh Columns and Refresh Formulas operations.

#### Invalid XML Character Issue Handling

Fixed an issue where invalid XML characters in partition data could cause read or write failures.

#### Customer Key Error Message Improvement
