Release Notes - **Release date: April 21, 2026** ### Improvements - We improved performance when Studio Pro exports pages and layouts for the React client during deployment. Apps with many pages, layouts, or snippet calls now deploy significantly faster. ### Fixes - We fixed an issue where offline data was lost when upgrading a native mobile app from 10.18 → 10.24+ directly, or from 10.18 → 10.19–10.23 → 10.24+. The database is now automatically migrated from legacy storage paths during upgrade. (Ticket 274811) - We fixed an issue where an app could reject valid localized dates for custom date patterns that use month names. This affected patterns with abbreviated month names such as `dd MMM yyyy` and standalone abbreviated month names such as `dd LLL yyyy`, so values like the Dutch `16 mrt 2027 10:02` could be treated as invalid. - We fixed an issue where MxBuild incorrectly reported that the modern web client bundler stopped unexpectedly, while the React client bundler completed normally without errors.
