We are proud to release v12.0.4, a massive milestone in the 12.x release series.

Highlights and core enhancements:

• support for very fast range queries over triples
• ISO8601 date, time, and interval predicates (Allen interval algebra) for WOQL
• schema context elements now managed atomically, introduced JSON for @context and @metadata elements in the schema.
• @context value as IRI in schema context, is provided as JSON-LD header value in document API if set (custom context)
• system is now prepared for heavy-duty enterprise usage overall (especially in enterprise version)
• at least 10% performance increase or more for reasoning-heavy workloads thanks to swipl 10 and other changes
• significant investment in lean memory usage and memory defragmentation for handling heavy sustained workloads
