Feb 1, 2026February 2026 (2026-02) — Focused on API clarity, stability, and build reliability across React Spectrum. Key features delivered include API clarity for the Table component, enabling smoother developer workflows and clearer data attributes, and improvements to local documentation builds. Additional improvements targeted accessibility and overall UI stability, while fixes to date handling and layout logic reduce edge-case risk for end users. Highlights: - Table API clarity: Rename colIndex to columnIndex in the Table component, with tests updated; aligns API with naming conventions and improves maintainability. (commit ba42d1850a1024edbcb0435d01ca2bf715f4729a) - DateField robustness: Fix keyboard cycling across Japanese eras and daylight saving time; add tests for times with placeholder zoned date times. (commit 12263afecad762074d7278625b16e59aac298ab1) - Docs/build reliability: Enable local documentation builds with the use of the 'use client' directive, ensuring docs render React components correctly. (commit 5959e26522eed27788d771cfbeea692a32772cdd) - Accessibility/UI polish: Update text color for selected table cells in S2 to improve contrast and accessibility. (commit 5abd94d4cf2990959bbae7771f1de19c9aa163b0) - UI stability fixes: Revert pressed-state customization and offset calculation changes to restore stable interaction and behavior in scroll/overlay scenarios. (commits 8b7f090ae5f12abefeb9291689b246fefc693871; 47858e06adcb8cd61eddaebb5cd007206f0995cc) - UI submenu positioning: Fix v3 submenu positioning for non-viewport containers, reverting unstable changes to ensure consistent overlays. (commit 0efd2d49f0b597b35c2ea46a7c5189c70da682d7)
