| Issue Area | Previous Behavior (Pre-24.4.120) | Fix in v24.4.120 |
|------------|----------------------------------|-------------------|
| Connection Timeouts | Long-running queries would drop during refresh, losing all unsaved work. | Timeout handling is significantly improved; large datasets now refresh without random disconnects. |
| Parameter Binding | Named parameters in SQL (e.g., @startDate) failed when reusing the same cell reference across multiple queries. | Parameter mapping is now persistent. No more “parameter not found” errors on second refresh. |
| Excel 365 (Current Channel) | Add-ins would occasionally fail to load or freeze on the “Loading data” spinner. | Full compatibility with the latest Excel 365 monthly channel builds. |
| Data Type Preserving | Date/time columns sometimes reverted to plain text or general format after refresh. | Column formatting (including custom number formats) now survives a refresh. |
