Mar 1, 2026March 2026 monthly summary for cryptomator/cryptomator: Delivered two high-impact updates focused on security, usability, and stability. Key changes include the Decrypt File Names UI improvements and the update warning system enhancements. The Decrypt File Names workflow now uses a single dialog per vault, removes path injection risks, resets the initial list on open, clears mappings on close, and cleans up unused fields, reducing UI fragmentation and security risk. The update warning logic now displays warnings only when no update is available by leveraging isUpdateAvailable(), improving accuracy and reducing user confusion. These efforts contribute to stronger security posture, lower support risk, and more reliable vault operations. Technologies/skills demonstrated: UI lifecycle management, security hardening, input sanitization and validation, code hygiene and refactoring, and readiness for future maintenance through clearer state management.
