Jan 1, 2026January 2026 monthly summary for themeum/tutor: Key features delivered include input handling improvements for payment settings, including input trimming to remove whitespace (notably in passwords), and enhanced form switch flexibility to allow undefined values, increasing component resilience. Currency module expanded to include Rwandan Franc (RWF). A dependency regression was fixed by reverting the js-yaml bump (4.1.0 -> 4.1.1) and removing added peer dependency declarations to restore stability. These changes enhance checkout reliability, broaden currency coverage, and reduce risk in builds.
