Released in late 2025, this version introduces groundbreaking performance improvements, a completely redesigned user interface, and powerful new features that position ERPNext as a serious contender against enterprise giants like SAP and Oracle.

Whether you're considering upgrading from v15 or evaluating ERPNext for the first time, this comprehensive guide covers everything you need to know about the most significant release in ERPNext's history.

The headline feature of ERPNext v16 is Frappe Caffeine – a revolutionary caching architecture that delivers up to 2x faster page loads and report generation. This isn't just incremental improvement; it's a fundamental reimagining of how ERPNext handles data.

One of the most requested features, the new Stock Reservation System allows businesses to reserve inventory against sales orders, ensuring committed stock isn't inadvertently allocated to other orders.
