Sep 1, 2025September 2025 monthly summary for haiilo/catalyst focused on stability, accessibility, and maintainability. Key features delivered include (1) Accessibility improvement: CatTooltip aria-describedby to enhance screen reader support, and (2) Dependency modernization: updated TypeScript, Babel, Stencil, and dev tools across relevant packages for stability and security. Major bugs fixed include (1) Tooltip interaction stability across devices and lifecycle, addressing reconnection of event listeners, cross-device listener addition, and cleanup on DOM disconnection to prevent orphaned tooltips, (2) Dropdown focus trap deactivation when the dropdown is removed from the DOM to prevent memory leaks, (3) CatDate lifecycle alignment to fix test warnings by switching initialization to the correct lifecycle stage, and (4) Form layout preservation within form groups to avoid overriding existing horizontal settings. Overall impact and accomplishments: Improved user experience with reliable UI interactions across devices, reduced runtime leaks and flaky tests, and a cleaner, more maintainable codebase. This work demonstrates strong cross-device event handling, robust lifecycle management, accessibility engineering, lint/style discipline, and proactive dependency governance.

Jun 1, 2025June 2025 – Haiilo/Catalyst: focused on reliability and correctness of the datetime UI component. Implemented a critical bug fix to ensure the time value updates correctly after a date change, addressing scenarios where time input could become stale after applying date-based limits. This change improves accuracy, data integrity, and user trust in the datetime functionality, and reduces edge-case failures in production.

May 1, 2025May 2025 performance highlights for haiilo/catalyst: Delivered an Adaptive CatTabs UI with responsive tab overflow via a More button, accompanied by refined width visibility calculations and guards to apply adjustments only when adaptive is enabled. Upgraded the framework (Stencil) and improved event data flow to support fromDropdown in catChange even when using cat-tabs. Also fixed non-adaptive tab behavior to ensure stable navigation across viewports, contributing to a smoother user experience and reduced edge-case issues.

Apr 1, 2025April 2025 (2025-04) monthly summary for haiilo/catalyst: Focused on improving testability, input masking, and dynamic UI behavior to accelerate release readiness and reduce QA cycles. Key features delivered include testId props for core components to enable automated tests, migration to cleave-zen with configurable date/time masks, and delayed initialization for the cat-dropdown trigger to support dynamically rendered triggers. Major bugs fixed: none identified in this period; no blocking issues reported. Impact: strengthens the foundation for automated testing, provides more flexible input handling, and improves UI performance and scalability. Technologies/skills demonstrated: UI component architecture, testability tooling, modernized input masking (cleave-zen), and dynamic component initialization patterns; alignment with CI/test automation and performance considerations.
