The text announces the release of Developer Preview 3 (DP3) of N1QL, a query language from Couchbase, highlighting its significant enhancements for creating complex data applications. The notable feature of this release is the introduction of JOIN operations, which enable the combination of related data objects, such as Customers and their Purchases, using INNER and OUTER joins. Additionally, the release includes NEST and UNNEST clauses for handling data in various structured formats, along with new array functions that simplify document model development. Users are encouraged to explore the documentation and utilize resources like a blog by Don Pinto and an online tutorial for further learning, while also registering for an upcoming N1QL webinar for more insights.
