redb 4.0 Released: XML Routes, Lazy References, Unique Keys and WS-Trust Across the Ecosystem
The redb ecosystem has delivered a major simultaneous release across all core components, bringing redb.Core, redb.Route, redb.Tsak and redb.Identity to version 4.0.0. The update introduces declarative XML routing, lazy object references, unique key constraints, and a full WS-Trust SOAP facade while closing multiple security issues reported through external audits and community feedback. Seventy-six NuGet packages, seven container images and platform archives for Windows and Linux are now available, with the Pro edition remaining free and license-free throughout the 4.x line. Significant internal changes include a unified expression language, support for modern data formats such as Protobuf and Avro, and improved handling of distributed caches and OpenTelemetry metrics. Security hardening covers header sanitization in all identity facades, consent-page protections, dashboard access controls and a switch to bcrypt password hashing. Existing clusters must be stopped before upgrade because mixed versions are not supported, and large databases require a maintenance window for schema changes and partial index creation.
