# May 26 Release (v21.20)
We are pleased to announce the release of **Fusion** **v21.20**. This update focuses on improving the connection management experience with greater flexibility and transparency, enhancing system observability through more detailed logging, and delivering meaningful performance gains for large-scale data operations.
***
## New Features & Improvements :sparkles:
### Connected App Selection & Error Handling
To help users avoid login issues caused by missing or misconfigured Connected Apps on Salesforce, we have introduced the following improvements to the connection management experience.
#### Connected App Selection
* A new **Connected App to Call** dropdown is now available in the connection dialog.
* When editing an existing connection, users can modify the **Connection Name** and the **Connected App to Call**.
* The **Login Mode** (e.g., Sandbox, Production, Community) is locked and cannot be changed in Edit Mode.
Connected App Selection
#### Re-Authentication Warning
* Changing the Connected App Type on an existing connection requires you to log in again.
* Selecting **Yes** keeps the new selection and triggers the re-authentication flow upon saving.
* Selecting **No** reverts the dropdown back to the previous value immediately.
* This confirmation dialog is not shown when creating a brand new connection.
Re-Authentication Warning
#### Improved Error Handling
* Connection failures during add or edit operations now display a descriptive validation error dialog instead of failing silently.
* The error dialog clearly explains the reason for the failure (e.g., *"Valorx Fusion Managed Package is not installed"* or *"Missing object permissions"*).
* If the connection attempt is manually cancelled by the user, no error dialog is shown.

## RECOMMENDATION
These changes allow the users to conveniently update the Fusion Windows client while they are planning to upgrade the [managed package v2.2](/valorx-fusion/versions-and-release-notes/fusion-managed-packages/version-2.2.md). We highly encourage customers to upgrade the managed package as soon as possible.

### Detailed Logging for Auto Update in Valorx Home Logs
The Auto Update process now provides detailed logging in the **Valorx Home Logs** panel, giving users better visibility into the steps and outcomes of automatic update operations.

### Performance Optimization of Clear Task
The **Clear Task** operation has been optimized to significantly reduce execution time when clearing record IDs based on specific conditions. This improvement is particularly impactful when handling large volumes of records, resulting in better overall performance and reduced processing overhead.
