Jan 1, 2025January 2025 – urlaubsverwaltung/urlaubsverwaltung: Focused on quality, reliability, and runtime stability through expanded tests, input normalization, and environment alignment. Key outcomes include expanded testing for WorkingTimeCalendar (tests for WorkingDayInformation.hasHalfDayPublicHoliday and 0.5-day scenarios with a half-day coinciding with a public holiday) with a refactored test structure; robust whitespace normalization in search queries to strip and collapse whitespace (including Unicode); and a Node.js runtime upgrade to 22.13.1 across .nvmrc and .tool-versions. These changes improve accuracy of leave calculations, reliability of search, and consistency of the development/runtime environment, enabling faster releases and reduced support overhead.
