Release Notes - **Release date: May 7, 2026** ### Improvements - We clarified the error message when upgrading solutions with files that have paths that are too long. ### Fixes - We fixed an issue where import and export mappings incorrectly showed consistency errors for microflows with unmapped optional parameters. Optional parameters now use their default values when not provided in the payload. Converter microflows must have exactly one required parameter which receives the value to be converted and may have additional optional parameters. (Ticket 250969) - We fixed an issue when an older offline client (from a Mendix version below 10.24.17) would fail to synchronize with an **HTTP 560 (Invalid JSONRequest)** error, preventing the offline app from loading. (Ticket 274811) - We added Microsoft-related MIME types. (Tickets 276471, 276598, 276604, 276958)
