### Improved User Experience During Initial Matrix Load

We’ve introduced performance and UI enhancements to handle large datasets more gracefully during Matrix load. Depending on the Matrix type, the system now shows clear progress messages, loading indicators, and limits lazy loading.

These changes help ensure smoother loading and better visibility into progress during Matrix generation.

### Optimized Matrix Queries for Better Performance

We've implemented subquery support in record selection and Matrix rendering. This enhances performance and ensures more efficient data handling — especially when working with large datasets.

### Matrix Rendering Limits

To ensure optimal performance and user experience, matrix rendering now follows defined limits based on matrix type. These limits help manage large data sets and provide clear guidance when limits are exceeded.

#### Single Object Matrix Limits

* **Y-axis (row) max limit:** 300,000 records
* **X-axis max limit:** 120 columns

#### Two & Three Object Matrix Limits

* **Y-axis (row) max limit:** 20,000 records
* **Data records max limit:** 300,000
* **X-axis max limit:** 120 columns

## 🐞 <mark style="color:blue;">Bug Fixes</mark>

We've addressed several issues in this update to improve your experience. Here are the details of the bug fixes included:

### **Matrix Timeline Shows Incorrect Dates Due to Time Zone Mismatch**

We've resolved an issue where the Matrix timeline displayed different date ranges compared to Salesforce. This was caused by a mismatch between the user's system time zone and Salesforce's locale. Dates will now consistently reflect the correct range across systems.

### **Unable to Assign Users to a Matrix in Wave Extension**

We fixed a bug where users could not be assigned to a Matrix — the AssignedUser field appeared empty in both the UI and network logs. User assignments now work as expected and are retained.

This hotfix release improves Matrix accuracy, stability, and performance. As always, thank you for your continued feedback — it helps us make Wave even better for you!
