Feature releaseReleased February 23, 2026

Structr 6.2.0

Structr 6.2.0 is a feature release with a major highlight: the new integrated documentation system is now shipped directly with Structr, providing comprehensive, searchable documentation right inside the UI. This release also introduces DoS protection for production hardening, improved global search with result highlighting, a comprehensive OAuth refactoring, and numerous bugfixes.

New Integrated Documentation System

The most significant addition in Structr 6.2.0 is the completely new built-in documentation system, fully integrated into the Structr UI. This replaces the previous external documentation with a comprehensive, always-available reference that ships directly with the platform and evolves together with it.

The new documentation features a dramatically improved structure and navigation, full-text search across all articles, Markdown-formatted function detail sections with code snippets, and extensive coverage of system types, services, built-in traits, and all built-in functions. New and heavily revised articles cover topics like URL Routing, Prefetching, RSS Feeds, Event Action Mapping, the Data Model, and Getting Started, among many others.
