Apr 1, 2026

April 2026 monthly snapshot across wso2/identity-apps and wso2/product-is focusing on UX improvements, data integrity, and release tooling. Key outcomes include frontend UI/performance and localization enhancements for outbound provisioning, robust handling of complex multi-valued attributes across Console and MyAccount, and clearer account recovery messaging in MyAccount. Strengthened release traceability with changesets for release tracking and batch updates, plus a security/UX improvement to hide the delete option for the logged-in user in the Console. In addition, a set of stability and quality fixes were delivered (lint fixes, email verification flow improvements, password update error handling, mobile number deletion guard in MyAccount, review-comment fixes) supported by test infrastructure stabilization via pre-creation cleanup steps. The combined effect reduces provisioning friction, improves data quality, enhances security, and strengthens deployment and testing processes.
