Feature Enhancements
- Handle auto cache invalidation for 4x build upgrades - Toolbar (GA-33) (GA-34):
We've upgraded the toolbar to automatically handle browser cache during 4x build upgrades, ensuring smooth logins and reliable access.
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.

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.
