Key improvements: - **Auto-cache cleanup**: When an agent is not logged in, non-essential cookies and storage from older builds are cleared—while preserving critical authentication, SSO, and CRM data. - **Login page refresh**: The system auto-refreshes the login page to load the latest version; if already open during upgrade, agents see a prompt to reload. - **No manual intervention**: Agents log in normally without refreshing manually, preventing login failures, UI inconsistencies, runtime errors, and stale data issues. **User Impact** - Smoother, hassle-free upgrades with reliable logins. - No disruptions or manual steps required. **Document **[Link](https://exotel.atlassian.net/wiki/spaces/ECC/pages/1426620431/Auto+Cache+Invalidation+for+4x+Build+Upgrades+-+Toolbar)** (Internal) ** **** # Technical Tasks There were no technical tasks performed in this release. # Bug Fixes ## System Common - ***is\_maskable patch handling in new and existing customers (GA-36):*** - **Issue:** Phone-related fields (such as phone1, phone2) were being masked unintentionally in CTI popups when addCustomerInfoToCRMUrl was enabled, even when data masking was not configured in the setup. - **Fix:** The logic has been updated to ensure that phone fields are masked only when masking is explicitly enabled in the setup. - **Impact:** This prevents unintended encryption of phone data and ensures consistent behavior across CTI popups and CRM integrations. - ***App Server Startup Stability (SL-17865):*** - **Issue:** An issue was reported where the App Server failed to start after applying a new database patch. - **Fix:** Necessary changes were implemented to ensure compatibility with the updated database patch, resolving server initialization failures. # Limitations and Known Issues - No new limitations or known issues have been reported for this specific release. # Browser and Platform Compatibility - **Chrome Version : Version 142.0.7444.176 (Official Build) (arm64)** # Contact Support For issues or queries, please contact Exotel contact center Support via the support portal or through designated email channels.
