Latest Updates
View all releases- Form Builder:
- Fixed issue where the same field could be added multiple times to a form. Fields already added to the form are now displayed as disabled (grayed out with a checkmark icon) in the "Available Fields" sidebar instead of being hidden or clickable. This prevents duplicate field entries and provides clear visual feedback about which fields are already in use.
- Name Database (Baza imion):
- New settings page for managing first names with gender assignments for grammatical personalization.
- Dynamic grammar syntax {{male_form|female_form}} for automatic gender-based word forms in emails and SMS.
- GenderService for centralized gender detection from name database with pattern-based fallback for Polish names.
- Support for country-specific name datasets (PL, DE, CZ, SK, FR, IT).
- Import/export functionality for name data (CSV format).
- Affiliate Program Module:
- Implemented complete affiliate marketing system (AffiliateProgram, AffiliateOffer, Affiliate, AffiliateCommission).
