- Improved auto-generated list/form/search views with priority fields, two-column form layout, statusbar widget, notebook for O2M fields - Enhanced fields_get with currency_field, compute, related metadata - Fixed session handling: handleSessionInfo/handleSessionCheck use real session from cookie instead of hardcoded values - Added read_progress_bar and activity_format RPC stubs - Improved bootstrap translations with lang_parameters - Added "contacts" to session modules list Server starts successfully: 14 modules, 93 models, 378 XML templates, 503 JS modules transpiled — all from local frontend/ directory.
