## GENERAL
With the final releases 4.0.0 and 3.5.1, we are setting a clear milestone in the continued development of the B2Bsellers Suite. Version 4.0.0 is now officially released and marks the start of the next generation, no longer in RC status and with full product approval.
Version 4.0.0 provides the technological foundation for upcoming features and stands for a modernized architecture, improved performance, and future proof development of the B2Bsellers Suite. The focus is clearly on sustainable scalability and a stable base for new features.
In parallel, version 3.5.1 is released as a targeted update for the 3.x line. It delivers important bug fixes and optimizations for existing installations and ensures that users of older versions can continue to benefit from stable and reliable operation.
## Focus on the Future: Version 4.0.0
With **4.0.0** we are continuing our work on the new generation of the B2Bsellers Suite. This release is all about greater efficiency, data transparency, and smarter process support.
- **Reworked budget function:** Budget management has been completely redesigned and now offers significantly more clarity, control, and flexibility. Companies can manage budgets centrally, adjust limits dynamically, and track usage in real time. We show how this works in practice in our [**Video about the new budget function**](https://youtu.be/jdGtCbB-1QY).
- **Catalog and price list export (available upon request):** Another new feature is the option to export product catalogs and price lists in various standard formats—individually upon request. Supported export formats: **CSV**, **BMECAT**, **Datanorm 4**, **Datanorm 5** and **EDIFACT Pricecat** This makes it even easier to integrate product and price data into external systems and exchange it with trading partners.
