March 2026
32 Commits • 18 Features
Mar 1, 2026In March 2026, cryptomator/cryptomator delivered a focused sprint of architectural improvements, security hardening, UI/UX enhancements, and expanded test coverage. The work improved reliability, security posture, and developer velocity, delivering tangible business value such as faster UI, safer host/trust handling, and a solid release baseline. Major changes included a code refactor moving logic into a dedicated controller, a smoother UI scene handling, and renaming classes/properties for clarity; security hardening with host allowUnknownHubHosts flag, default distrust of non-local HTTP, and trusted cryptomator.cloud subdomains; UI enhancements with a reset trusted hosts feature, plural labels, and improved sorting; comprehensive tests added and stabilized; deduplication improvements and consistency checks; and release/readiness steps culminating in version bump to 1.19.2 and release metadata updates. These changes reduce risk, improve data protection, and enhance user experience.
